Instruction Manual
Description
AP Series are frequency agile TV channel processors that provide visual and aural RF carrier outputs on any Broadcast or
CATV channel in the full 50 to 550 MHz (AP xx-550B) or 750 MHz (APxx-750B) frequency range from any VHF or UHF RF
input source. They have an exceptionally low out of band noise floor that permits the construction of multiple channel
headends without auxiliary filtering. Efficient AGC assures a wide dynamic range and dual SAW filters provide superior
selectivity.
The processors are available in either 60 dBmV (AP 60-xxx) or 40 dBmV (AP 40-xxx) output versions. DIP switches for
setting the input and output frequencies are accessible from the front panel, as are the A/V ratio, output level, FCC
aeronautical offset controls and flatness control.
An external IF loop-thru enables the replacement of the standard IF signal with an alternate source of composite IF
(such as an “all-call” system) or the insertion of IF scrambling equipment. An on-board carrier substitution generator is
automatically activated upon loss of input signal. A high isolation IF switch is included to allow for an EXT IF input which
can be used for EAS capability.

Switch 2 is used to set the unit input/output channel number.
Channel setting is accomplished by setting the switch to the desired input/output chan-
nel.
Switch 2 is divided into 2 sections, the Tens section and the Ones section.
In each section, there are 4 switches labeled - 8,4,2,1. Each correspond to it’s respective
numeric value.
A simple chart, shown below, gives the corresponding switch positions for Tens position,
1 to 12 and for the Ones position 0-9.
The user sets the Tens section and the Ones section together to set the desired channel.
The artithmetic sum of the values of both the Tens section and the Ones section is equal
to the channel number to which the unit is set.
Example: For CH 116, set 11 Tens and 6 ones for 116.
For single digit channels, the Tens switch is set to zero.

(Do not insert jumper when manually switching.)
Automatic Manual
Adjustments
OUTPUT LEVEL
Connect a suitable RF indicator such as a Field Strength Meter (tuned to the visual carrier frequency) or a Spectrum
Analyzer to the RF output of the modulator or a system monitor point and adjust the Output Level control to the desired
reading of the visual carrier.
A/V CARRIER RATIO
To adjust the aural-to-visual carrier ratio, tune the RF indicator device to the aural carrier frequency and adjust the Aural
Level control to obtain the desired aural carrier level. Note that you cannot obtain a ratio smaller (that is, the aural level
relatively higher) than that of the incoming RF signal. Recommended ratio is -15 dB.
STANDBY CARRIER THRESHOLD
The Standby Carrier Threshold is factory-set for -19 dBmV. If it is necessary to set the threshold to some other level, pro-
ceed as follows before installing the AP Processor in its rack or cabinet.
1. Plug the AP Processor power cord into a 117 VAC, 60 Hz outlet. The green Power LED on the front panel will light. A
warmup period of about 30 minutes is required to stabilize the equipment.
2. Set the AP Processor to the desired input and output channels.
3. Connect a television receiver (tuned to the output channel) to the rear-panel RF OUT terminal;use the RF OUT con-
trol and attenuators as required to avoid overloading the receiver.
4. Using a variable attenuator and a signal level meter, adjust the input signal to the desired threshold level.
Connect the input signal to the RF INPUT terminal.
5. Locate the Threshold Control, R32.
6. Adjust R32 so that the picture just switches between the input signal and the standby carrier.
Use the television receiver as an indicator.
7. After making the adjustment, disconnect the power cord and input and output cabling.
8. Install the unit in its mounting location.

Option 4 - Sub-Band Output
Description
Option 4 extends the output frequency range of an AP processor to include sub-band channels T7 through T13.
This permits the unit to be used for sub-band via the return path in a two way system or as a LAN processor.
All external controls and connectors remain the same as a standard model. Video and Audio specifications for
channels T7 through T13 also conform to standard processor performance. RF specifications remain the same except
for the following:

Option 14 - ON CHANNELOCK
ON CHANNELOCK solves one of the commonly encountered problems of using an Agile Processor in the ON Channel
Mode. (e.g. channel 9 VHF input, channel 9 VHF output).
The problem being addressed manifests itself as picture “flutter” similar to the effects of signals reflected from aircraft
(although it is caused by a different phenomenon). The flutter most often occurs when the input signal is an off air
antenna or antenna/preamplifier combination.
Option 14 is intended to be invoked only when the input is channel 2 - 13 broadcast and the output channel is the same
as the input. Do not invoke Option 14 for conversions. Option 14 is invoked by Switch SW3, POSITION 1. Switch SW3,
POSITION 1 is found in the bank of front panel accessible input channel selector switches. Place Switch SW3, POSITION
1 down to invoke Option 14, up to disable Option 14. Also switch SW-1 POSITION 4 OFF when using Option 14.
As a reminder, turn “offset adjust” potentiometer fully clockwise when using this processor on the “ON Channel” mode
regardless of whether the processor has Option 14 or not.
When setting up a processor for “ON Channel” operation be certain that the switches for the output selector are as
required for “ON Channel” operation. Use the following procedure for best results when in the “ON Channel” mode and
when using Option 14.
1. Switch SW-1 POSITION 4 is switched OFF when using Option 14 and ON to adjust for frequency offsets.
2. Set Front Panel Offset Adjust Control fully clockwise.
3. Switch SW-3, POSITION 1 is down to invoke Option 14 ON. Move to the up position for Option 14 OFF.

Option 17 - Sub-Band Input for AP60
Description
The sub-band Option 17 consists of a block converter placed before the product's main RF input. The converter trans-
lates the entire T-channel band (5-50 MHz) to the high VHF TV band (173-218 MHz), and presents this as the sub-band
converter output on the rear panel. This output is coupled via a short coax jumper to the basic product's RF input. The
converter local oscillator operates at a frequency of 168.25 MHz. Therefore, at the output of the converter, standard
"T" channels appear as channel "7" for "T-7", channel "8" for "T-8", and so on. Selection of the appropriate T-channel to
be processed is made via the front panel input frequency select DIP switches following the channel "7" settings for T-7,
channel "8" settings for T-8, and so on.
A complete frequency selector chart is provided below. In addition, one may use the frequency chart supplied with the
product by following the settings for standard broadcast channels 7-13 as if they were T-7 through T-13.
The sub-channel converter has a conversion loss of approximately 8 dB. Therefore, a nominal input signal level to the
sub-band converter should be between 3 and 23 dBmV to ensure proper operation.
Connections for Sub-Band Options
1. Set the Sub-Band selector located on the back panel to the ON position.
2. Connect the cable containing the Sub-Band channels (T-7 thru T-13) to the Sub-Band input.
3. Using the supplied loop-thru cable, connect the Sub-Band output to the RF input.
4. Set Switch 1 to the STD Mode. Set the AP60 front panel switches (Input Channel Selector) for the desired
Sub-Band channel by using the chart below:
For operation of the AP60 with Non-Sub-Band channels, set the Sub-Band Selector to the OFF position and connect the
coax cable from the system to the RF Input on the back panel.

Option 12 - Automatic Broadcast Offset Correction (ABOC)
With the use of Option 12, all input offsets are fully corrected to allow precise control of output offsets. This allows
for control of FCC 21005 Offset requirements completely independent of the input offset. Using Option 12, there is no
need to measure or determine the input offset frequency whether it is broadcast or from a cable channel. All inputs up
to ±25 KHz offset are fully corrected. Once selected, the output channel will maintain that offset even if the input offset
varies. A green Front Panel Indicator shows that the ABOC is on and the input offset has been fully corrected.
Option 12, ABOC should be turned on when using an AP as a converter in the “Off-Channel” mode where the ouput
channel differs from the input channel. The input channel is selected by means of Front Panel DIP switches
corresponding to the input channel. The output channel is selected by Front Panel DIP switches and set according to the
output channel. ABOC On/Off position controls ABOC operation. With the 4th switch UP the ABOC is activated and the
output offset frequency will be maintained independent of the input offset. It is recommended that the ABOC be kept
on during “Off-Channel” operation, thus keeping the output offsets controlled.
During “On-Channel” operation, the ABOC should be switched off. In this mode, the output frequency will remain
exactly the same as the input frequency.
During “Off-Channel” operation with the ABOC off, the output offset will no longer be accurate but will be a
function of the input offset which may be unknown.

year from the date of original purchase (or such shorter period of time as may be set forth in the license agreement specific to the particular
software being licensed), with respect to iCentral™ (hardware and software) and all other software products (including embedded software)
licensed from BT, (ii)) for a period of one (1) year from the date of original purchase, with respect to all MegaPort, IPTV products and fiber

and other terms of such third party vendor’s warranty. In addition, notwithstanding the foregoing, (i) certain Closeout Products that are not

warranty for Refurbished or Closeout Products. All sales of Refurbished or Closeout Products are final.

OTHER LEGAL THEORY ARISING DIRECTLY OR INDIRECTLY FROM THE SALE, USE, INSTALLATION OR FAILURE OF ANY
PRODUCT ACQUIRED BY BUYER FROM BT.
