1- INTRODUCTION

The SEPsoniX FM processor is a complete, single-rack mount instrument, which contains all the necessary

functions for conventional FM broadcast audio processing. It incorporates many of the features found in the

high dollar FM processors, yet includes additional features not found in those same high-dollar devices.

Some of those features include:

•Independent compressor out – to send signals to internet streams or external monitoring.

•Programmable FM signal generator – allowing the processed output to be monitored locally on an FM

modulation monitor/FM tuner, particularly for in-studio processing requirements.

•No-latency design- this allows air talent to be able to listen to the the off-air audio in real-time.

The SEPsoniX FM processor contains the following featues:

•Stereo operation,

•Broadband, smooth-riding AGC,

•Two bands of limiting,

•Compression 'freeze'; eliminating audio breathing during gain changes,

•Ultra-fast true-stereo pre-emphasis limiter (50-75-100uS selectable)

•Stereo generator with digital balanced modulation of the 38kHz subcarrier,

•Adjustable composite transient peak suppressor with LED indicator,

•All controls front-panel multi-turn adjustments,

•LED indicators: input Vu, dual-color band limiting, HF limiting, Composite clip, Stereo ON,

•SCA/RDS input,

•XLR/Phone balanced inputs, RFI protected,

•Post-Compressor output (0 or -10db)

•Optional frequency-agile FM signal generator, 87.7-107.9MHz, 100kHz steps, -10dBm RF output level.

•90-250VAC 50-60Hz AC input

•Single 1RU enclosure 12" depth.

SEPsoniX is designed to accept unprocessed audio, direct from a program source, and not require additional

processing for desired on-air result, The functionality of the device is engineered to:

1) Control audio gain as much as 30dB, compressing the audio content and levels that may not be

normally adjusted and monitored by the user,

2) Compensate for the effects of over-modulation from the effects of high-frequency pre-emphasis,, by use

of ultra-fast pre-emphasis audio limiting, independently of L&R channels,

3) Prevent "ailising" distortions that may occur in the stereo generaton process, though the use of active

15kHz low-pass and 19kHz notch filtering of the audio,

4) Contain an FCC-compliant stereo generator,

5) Employ the use of an adjustable composite transient peak supression circuit, preventing peaks of

frequent recurrence from over-modulating the composite envelope, without affecting pilot injection,

6) Provide a stereo post-limiting output signal, for use in streaming applications, or external processed

audio source,

7) Contain a frequency-agile, PLL synthesized signal generator (if installed), capable of sending processed

audio to a modulation monitor or FM tuner, for the purpose of direct off-air monitoring,

8) Produce no measurable audio latency through the processing path.

9) Allow the user rapid setup and installation with no need for menus, touch-screens, or expansive setup

procedures.

The SEPsoniX FM processor factory-set filters, time constants, and parameters are optimized for a variety of

music formats, and create non-fatiguing audio quality, yet maintains a loudness factor in which the audio will

remain competitive yet clean. The simplified installation and setup reduces the need to spend countless hours

of adjustment, and reduces the need to undergo countless listening tests. With just a few minutes of

adjustments, the SEPsoniX processor can be ready to provide years of service.

All voltage controlled gain stages utilize digital PWM (pulse-width modulation) technology, which provides

superior gain control, eliminating the anomalies that occur with linear type gain control electroncs, virtually

temperature-independent, and extremely high gain linearity between left and right channels. Using 6x

oversampling, the need for complicated PWM filtering circuitry is minimized.

The SEPsoniX FM processor contains several basic blocks to perform the necessary functions. Refering to

the block diagram above it includes:

1) An input conditioning block, which consists of an RFI-protected audio input amplifier, adjustable to the

nominal input signal. This is simplified by observing a front-panel LED Vu meter, and setting the levels

for nominal readings. The input is then passed through a 25Hz, high-pass filter, with an 18dB/octave

slope. This will reduce any audio subsonics that typically cause undesired results in audio processing,

and on-air anomalies in some transmitters. Audio is then passed through an all-pass phase shift

network, which helps compensate for asymmetrical audio peaks.

2) A broadband automatic gain control stage automatically adjusts for long range gain changes, as much

as +/-15dB. The detection of the gain is dependent on the peak limiter stage content, and derives the

control voltage from the output of the peak limiters. This allows for smoother gain-riding with varying

program content.

3) A dual-band peak compressor, with factory-set time constants, which processes audio independently

above and below 200Hz. Time constants are factory-adjusted so that the audio compression attack time

is fast enough to respond to progam content, and a responsive release time providing a non-fatuiging

audio quality. Front-panel dual-colored LED's show the operation of the compressor stages, changing

from green (normal) to high (red). Additionally, the use of compressor 'freeze' circuitry will cause any

gain changes to be suspended whenever program content suddenly stops. This prevents the

compressors from gain-riding during silent program content, reducing the 'breating' effect of

compression release times, which results in noise build-up, and un-natural audio quality. The

independent bands are then summed together, and passed through a safety low-pass filter, which

eliminates any ailiasing distortions that may occur into the pre-emphaisis limiter, as well as any

remaining switching products from the PWM stages.

4) The next block is an ultra-fast PWM-controlled pre-emphasis limiter, which responds to instantaneous

high-frequency audio that exceeds the internal limits along the 75µS (50µS and 100µS internally

programmable) pre-emphasis curve. The limiter is only affected by high frequencies (rather than the

peak level of the pre-emphasized audio content), eliminating the possibility of modulation of high

frequency content caused by low-frequency program content. The limit threshold is set internally, so that

the limiting can occur with the correct balance between high and low-frequency program content. The

user can adjust the input gain to the high-frequency limiter, if additional emphasis is desited on the

program content, resulting in an increase in the total audio drive to the stereo generator, while

increasing the amount of pre-emphasis limiting simultaneously. The amount of high-frequency limiting is

indicated with front-panel LED's.

5) Processed audio is then routed through a 6-pole active 15kHz low-pass filter, which eliminates any

frequency material that may be outside the desired audio passband. In addition, the use of an active

19kHz notch filter reduces the chances of any audio components interfering with the stereo 19kHz pilot

signal.

6) Filtered audio is passed on to the stereo generator, which produces the stereo baseband signal. Front

panel controls can enable the stereo pilot signal, indicated by an LED. When switched to MONO, the

19kHz pilot/38kHz carrier are fully turned off, and both Left and Right channels are summed into the

main channel. This eliminates the need to combine both program channels to a single input,

occasionaly required with some conventional processors. The stereo generator utilizes the 'matrix'

technique, as opposed to the 'switching' method. This eliminates the need for a costly baseband filter,

and only needs to modulate the L-R component. When in Mono, L+R component is passed directly as a

mono composite signal. The 38kHz L-R digital balanced modulator is superior to analog modulators,

and is essentially drift-free with regard to carrier suppression and temperature variations. The stereo

generator is internally factory aligned for optimum performance, and does not require re-calibration on a

normal basis. Pilot phase and injection are adjustable with multi-turn front-panel controls.

7) A composite transient peak-supression limiter (AKA "composite clipper") protects the composite signal

from exceeding the allowable FM deviation limits set by the radio broadcasting rules. Front-panel

control adjustable, and utilizing an LED indicator, the LED provides the user a visual gauge as to the

degree of transient peak-supression occuring in the composite transient limit process. The transient

supression limiter does not affect the 19kHz pilot injection, and will not cause any effect on the 19kHz

pilot signal. The pilot signal (and a fixed external SCA/RDS input on the rear panel) are summed into

the peak-supression output, and final output of the composite signal is split, and one path routes to an

adjustable front-panel control for the main composite output on the rear panel.

8) The second split of the final output is routed to an internal frequency-agile FM signal generator (if

installed). The FM signal generator is capable of delivering an RF output to a rear panel jack, for the

purpose of monitoring the processed audio on a local FM monitor or tuner. The nominal output level

(typ. -10dBv) is sufficient to drive the receiver input of a modulation monitor, without the need for any

RF amplification to the monitor. Contained on the signal generator is a set of DIP switches to set the

frequency between 87.7-107.9Mhz in 100kHz increments, and a modulation calibration adjustrment for

final modulation adjustment.

9) The compressor output (L,R) is routed to a set of unbalanced rear-mounted jacks, for the purpose of

sending processed audio to a monitor or audio streaming device. The line output can be internally set

for either 0dB or -10dB. This audio follows the dual-band compressor output.

2- INSTALLATION

It is important that the SEPsoniX chassis be properly connected to a good earth ground. At very high

frequencies (VHF), wire leads do not provide sufficient grounding. The best method is to ground the

SEPsoniX to a well-grounded equipment rack, which should be connected to the station or building ground

with wide straping. To make a good electrical contact between the SEPsoniX chassis and eqipment rack, it

may be necessary to scrape the paint from the SEPsoniX mounting flanges and rack cabinet. If necessary,

measure the resistance between the rack and SEPsoniX chassis, and assure that it is less than 0.5 ohm.

REAR PANEL DESCRIPTION

Refer to the diagram above diagram for the rear panel description.

1- AC Power in- Connect to AC power source (90-250 VAC) using the supplied grounded IEC power cable. If

you are wiring directly to AC mains, follow this color code:

wire color function

Green or Green/Yellow: Earth (Ground)

Brown or Black AC hot

Blue or White AC neutral

note: Internal power supply is fuse protected against overloads and shorts. Do NOT replace with a fuse of

higer rating than specified.

2- Audio Inputs (L & R)- These are female XLR or female TRS 1/4" jacks, with the following pinout

xlr pin 1/4" plug description

1 sleeve earth ground

2 tip audio in +

3 ring audio in -

In a high RF environment, it is recommended that a fully-balanced source connect to the input jacks of the

SEPsoniX, using a well shielded cable (similar to Belden 8451). Connect shield of cable at both ends for best

performance. In addition, your source should also be well gounded to earth.

In low RF environments, it is best to connect the shield at one end only. Avoid unbalanced connections, but if

necessary, limit length to less than 20 feet. When connecting to an un-balanced source, do not connect the

audio (-) lead directly to the SEPsoniX chassis. Instead, tie the (-) lead at the source ground, and do not

connect the shield at the source.

SEPsoniX will operate over a wide range of audio inputs, ranging from -10dbV (re:0.775v) to +24dbV. Try to

avoid input levels greater than +20dbV, as adjusting the input level correctly may be difficult to achieve.

It is very important that the input connectors are wired in phase, otherwise your mono audio will cancel, and

you will only hear 'echos' or very hollow sounding audio in the main channel.

The audio inputs are at a 10K (bridging) resistive load, and should originate from a low impedance source

(typically 600 ohm loads from most audio equipment is standard).

3- Composite out- This output is capable of driving at least 4v p-p into a 2k load. It is recommended to use a

6' or less well shielded 50-75 ohm coaxial cable length between the SEPsoniX and FM transmitter.

4- SCA/RDS in- This 10k-ohm resistive input allows for subcarrier/multiplex insertion of the main signal, and is

mixed with the pilot injection signal in the SEPsoniX. Signals such as SCA or RDS can be inserted at this input,

and the external drive level must be adjusted for proper injection into the

multiplexed signal.

5- Post Process Out- This is an isolated post-compressor output.This

output can connect directly to most computer sound card AUX/Line level

inputs. It is recommended to use the -10dB level set for computer feeds. It

has a drive impedance of 2k ohms. Care should be taken when

connecting this output in a high RF field, and audio isolation

transformers may be needed to reduce the potential for ground loops.

This output is an unbalanced line level post-compressor output, and can

be set to either 0dB or -10dB below reference level. See diagram on

right for for the jumper detail.--------->

You can alternately connect to a streaming source, or audio amplifier,

for local/remote monitoring.

6- RF OUT- This is the RF output of the frequency-agile signal generator(if installed), and will drive a 50-75

ohm load, with an average output level of -10dBm re:1mW. This output will allow the user to monitor the audio

performance, or for use as an in-studio monitor on an FM receiver with an antenna RF input jack, such as a

modulation monitor RF input NOTE: THIS RF OUTPUT IS NOT INTENDED TO BE CONNECTED TO AN

ANTENNA FOR USE AS A TRANSMITTING DEVICE!

FRONT PANEL DESCRIPTION

Refer to the diagram above diagram for the front panel description.

1- Power indicators- These LED's will indicate when AC power is applied, and they will both illuminate. If

either LED is out, there is an internal issue with the power supply circuitry, and the unit will not operate properly.

2- Input gain controls (L&R)- These multi-turn controls adjust the audio input level, as indicated by the (3)

LED Vu meters. Adjust input for 0Vu, with peaks to +3 to +6 range. Avoid excess peaks above +6, as this will

cause higher levels of compression, which may not be desired. Input can operate at high peaks, however,

compression will be greatly increased, and may cause a more 'dense' sound.

4- Compression level indicators- These dual-colored LED's show the approximate amount of compression

for the Low and High bands. When green, this indicates approx 6dB of compression, and red is 15dB or over.

These are dependent on the program content, input levels, and spectral energy in the dynamics.

5- Drive (L&R)- These multi-turn controls increase the drive to the HF limiter, which also increases the amount

of HF limiting that will occur. Increasing the level of these controls will also increase the drive to the composite

transient supressor circuitry.

6- HF Limit indicators (L&R)- These LED's will illumunate as the intensity of HF limiting increases. The

amount of HF limiting is program and level dependent, and may vary widely with a diversity of program content.

Increasing the Drive (5) control will increase the density on the HF material, as well as increase the drive to the

composite peak supressor circuitry.

7 & 8 - Stereo/Mono selector & Stereo LED indicator- This pushbutton, when depressed, will place the

SEPsoniX in stereo mode, and when released, mono. This switch (when in MONO) disables the master

oscillator for the stereo subcarrier and pilot. The Stereo LED indicator is connected to the oscillator circuitry,

and shows active oscillation when illuminated. When in mono, the Left and Right channels are summed, and

the entire sub-carrier is shut down, only allowing main channel (L+R) to exit the SEPsoniX output.

9-Pilot Level adjustment- This multi-turn control adjusts the pilot injection level, and should be carefully set

with the proper monitoring equipment.

10- Pilot Phase adjustment- This control adjusts the phase relationship between the pilot and subcarrier

frequencies, and should be set for maximum separation between left and right channels.

11 & 12- Transient peak supressor drive (Comp Clip level) & Composite Clip indicator- This control

adjusts the amount of signal drive to the peak supressor (AKA "composite clipping") and should be used with

discretion. The Composite Clip indicator LED will illuminate on transients at the clip level, and the increased

brilliance will indicate more agressive clipping. NOTE: The use of composite clipping should be used with

discretion, as excess clipping will affect stereo separation, and increased peak distortion of severely over-

driven. Increasing the DRIVE (5) controls will also increase the amount of clipping. A variation between the

DRIVE and CLIP LEVEL can affect the density of high frequency limiting-to-clipping ratio, and subjective testing

should be conducted to obtain desired result.

Occasional flashing will be normal, and byproducts are not easily heard unless the flashing intensity is long and

steady flashing of peaks over the clip threshold. What will be noticed is a 'scratching' sound in the stereo

image, appearing in both channels simultaneously. Increased clipping will add to this sound until the separation

is degraded to a point of sonic infeiority.

13- Output level- This is the final output drive to the exciter/FM transmitter. The mult-turn control will provide

fine resolution of the audio envelope driving the exciter, and should be setup with a modulation analyzer or

other means to assure FM deviation does not exceed the legal limits.

Note: Increasing this control increases the TOTAL modulation to the transmitter, including: Pilot, External

Multiplex audio, and processed audio (post clipped).

INTERNAL CONTROLS

1- Pre-emphasis select- These jumpers, factory set

at 75µS, select the pre-emphasis curve for the pre-

emphasis range. They can be set for 50, 75, or 100µS

for left and right channels. They are located on the main

board, in the middle section. ---------------------------------->

<--

2- FM Signal Generator modulation/frequency set-

These controls are located on the FM signal generator

PC board, in front of the the rear-panel audio input PC

board. Switches are read on power-up, or when RESET

button is depressed on the PC board.

Connect modulation monitor source to RF output jack on the SEPsoniX rear panel. Set modulation to desired

level by adjusting the Modulation Gain control on the left-hand side of the board. Clockwise rotation increases

modulation percentage.

3- OPERATION

MAIN SIGNAL FLOW SETUP

To best setup the SEPsoniX desired operation, it is recommended to connect an oscilloscope to the

composite output jack before placing the unit on the air. You can also monitor the audio result from the internal

FM signal generator RF output, by conneting a radio receiver or modulation monitor to the RF output jack of

the SEPsoniX. This will prevent the chance of overmodulation or annoyances to the listeners while making

adjustments. By observing the output on the scope, you will be able to adjust output levels more

proportionately, as well as see any undesired effects of over-processed audio.

Once your SEPsoniX is installed and operational, supply desired program content to the input jacks, and

adjust front panel input gain controls to desired Vu readings. You should start to see the compression LED's

flashing green and red, depending upon program dynamics, program content, and input levels. HF limiting

LED's will also flash, depending on the levels/program content,etc., and drive level settings to the HF limiter.

You can place the SEPsoniX in Stereo, and the Stereo LED will illuminate. Set the pilot level to optimum

initial setting, as it may require re-adjustment once desired output "envelope" is set. Placing the switch in

Mono will sum left and right channels, and remove all stereo sub-carriers. (Switching between Stereo/Mono will

NOT affect any external Multiplexed insertion signals).

Optimum separation is obtained by adjusting the PILOT PHASE control. To properly adjuist, disconnect one

audio input channel, and adjust the PILOT PHASE control until the disconnected channel audio reaches a

'null'.

Observe the Composite Clip LED; increasing the HF Drive will cause the Clip LED to also increase in intensity

to some degree. Adjusting the composite clip drive level will cause the output to approach a point where

noticeable 'flat-topping' of the waveform will occur, with the pilot riding along the top of the flat-toped wave. This

is the point where the transients will not be any greater than the "flat topped" reference level.

Increasing the amount of flat-topping (by increasing either the CLIP drive or HF drive) will increase percived

loudness without increasing modulation peaks, but excess flat-topping will cause degredation of stereo

image/separation. Adjust the amount of clipping with descretion, and desired result. Excessive flat-topping may

cause audible distortion on some program content, and should be avoided as to reduce listener fatigue.

If more HF limiting is desired, you can increase the HF drive controls, and reduce the CLIP drive until a desired

sound is obtained. Subjective listening will result in the best and desired result.

Once desired output envelope is obtained, connect Composite Output to transmitter, and adjust modulation for

desired deviation with OUT control.

POST PROCESSING OUTPUT SETUP

Connect external audio device (computer, network stream, etc) to RCA jacks on rear panel. These jacks are

recessed so that accidental impacts will not damage the connectors. Since this is an unbalanced output, be

sure connections to audio devices do not produce any ground loops; it may be necessary to install audio

isolation transformers (Triad TY-145P will work well if connected to high-Z input) to reduce the chance of audio

ground loops. Observe polarity on transformers for proper phasing into equipment.

The output level is fixed at either 0dB or -10dB below reference, and can be changed with the configuration

jumpers detailed in section 2 (Installation).

FM SIGNAL GENERATOR PROGRAMMING (if installed)

The frequency selection process is set by three 4-position DIP switches. Each set controls the frequency in

decades of 100kHz, 1MHz, and 80, 90, or 100MHz increments.

Each set range is a count between 0-9, and any numbers greater than 9 will default to the value of 9. Any

attempt to set a frequency outside the range specified in the frequency limits will result in either the lowest or

highest frequency available The count uses inverted logic, where ON= 0 and OFF=1. Binary math is used to

set the desired frequency. For example, if 99.5 Mhz is desired, the DIP switches (LSB on the left) would be

0101 0110 01x0 (0.5 9 90)

The DIP switch farthest to the right is a "Locked Reset" setting, and if set to ON, will keep microprocessor

disabled in a permenant locked mode. This will prevent any setting of the RF output frequency. Leave this

switch in the OFF position when using the Signal Generator.

To program RF frequency, set DIP

switches in accordance with chart,

then either reset power, or press

RESET button on PCB. Signal

generator will then advnace to

programmed frequency, and remain

on this frequency each time the

power is cycled.

Note: Setting DIP switches greater

than 9 on 100kHz or 1MHz switches

will default to a value of 9.

note: when changing frequency, it may be necessary to re-calibrate modulation level. Due to change in

VCO voltage, modulation sensitivity changes with frequency

ADJUSTMENT RANGES:

Input range: -15 to +25dBv re: 0.775v RMS 600 ohm source

HF Drive range: up to 6dB.

Stereo Pilot range: fully adjustable at any output setting for guranteed 8-10% injection

settings.

Comp transienet limit range: up to 6dB.

Signal Genertor tuning range: any frequency from 87.7MHz to 107.9 Mhz, in 100 kHz steps.

FACTORY SETTINGS:

The SEPsoniXis factory set to the following adjustments:

Input level 0vU @ 400Hz: 0dBv re:0.775v 600 ohms

HF Drive: 50% of range (-3dB)

Output level: 4v P-P, into 1k ohm load

Mode: Stereo

Pilot injection: 9% injection of 2V RMS output level.

Composite clip level: 2dB clipping

FM generator frequency: 107.9 Mhz

FM generator audio level: Calibrated to +/- 75kHz deviation with compisite

processing and stereo pilot engaged.

ADDITIONAL PRE-PROCESSING DEVICES

It may be desired to connect additional audio tailoring to the SEPsoniX,for the purpose of additional progam

frequency equalization, dynamics processing, or other audio effects for specalized requirements. When doing

this, the additional tailoring will affect how SEPsoniX responds, including reacting to frequency emphasis,

gain-riding, or preceived loudness. Keep in mind; over-compensating for program content may or may not

provide desired results, and subjective listening tests should be conducted before determinig how much

external tailoring is needed for expected performance.

5- TROUBLESHOOTING

stereo generator calibration procedure:

If it becomes necessary to re-calibrate the stereo generator, you will need at least a 20MHz oscilloscope, and a

sinewave audio generator. To re-calibrate:

1) Connect signal generator to input terminals of device, set frequency to 400Hz, sinewave output, line

level out( 1vRMS is satisfactory),

2) Adjust input levels on front panel until dual color compressor LED's are barely indicating green

illumination.

3) Connect oscilloscope to composite output, and set waveform for visible deflection of approx 1/2 full

vertical scale range.

4) Set unit to Stereo mode, Blue stereo LED should illuminate.

5) Set pilot level fully CCW so that no obsevable pilot signal is seen on output.

6) Disconnect audio inputs, and increase sensitivity on scope so that the noise floor can be seen.

7) Adjust L-R NULL for minimum output, or as low as visibily possible. You can alternately connect a low-

frequency spectrum analyzer to the composite output, and adjust the 38kHz carrier level for minimum

output. Re-set vertical gain of oscilloscope to setting in step (3) above.

8) Connect audio Right channel and observe oscilloscope. Adjust L-R GAIN for flat baseline.

9) Increase audio frequency to 10kHz, but reduce audio generator input level by 15dB. Avoid HF limiter

LED's from illuminating, and reduce audio level further to refrain from HF limiting action.

10) Adjust L+R PHZ for as flat a baseline as possible. Reset audio generator to 400 Hz, and increase level

as in step (1) above.

11) Disconnect left audio in, and connect Left audio in.

12) Adjust L-R BAL for flat baseline

13) Repeat steps (8) and (11/12) so that baseline is equally flat for left and right channels. Repeat step

(10).
