WARNING! RISK OF HAZARDOUS ENERGY!
TO REDUCE RISK OF ELECTRIC SHOCK OR FIRE DO NOT
EXPOSE TO RAIN OR MOISTURE.
NO USER SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
UNIT MUST BE EARTHED AND CORRECTLY FUSED.
Magnetic Field - Caution
If an equipment rack is to be used, we would
recommend mounting the amplifiers in the bottom of
the rack and mounting pre-amplifier and other
sensitive equipment such as the Cred Mk2 at the top
of the rack.
Do not locate sensitive high-gain equipment such as
pre- amplifier or tape decks directly above or below
amplifiers.
Because amplifiers have a high power density there is
a strong magnetic field which can induce hum into
unshielded devices that are located nearby. The field
is strongest just above and below the unit.

Channel Select Buttons
The currently selected input or output channel is shown in the top left corner of the display. Pressing
the channel select buttons scrolls through the available inputs and outputs. If operating stereo linked
the channel pair is shown. For example ‘CH A+B’ means both input A and B parameters.
Display
The LCD Displays preset and parameter information. The default screen is shown after start up and
displays the number of the current preset on the lower line of text. When navigating around the
adjustable parameters, other information is shown.
Edit Select Buttons
The name of the edit parameter page is displayed in the bottom left portion of the LCD. Pressing the
edit select buttons moves through the available parameter pages for the current input or output.
Mute Buttons
The LEDs next to the mute buttons indicate their current status. Pressing a mute button toggles
between the mute on and off.
Parameter Knobs
Up to three parameters are shown on the display. The parameter name is shown with its' current
value below. Where appropriate, parameters are grouped according to function. For example the
parametric equalisation page shows centre frequency, width and gain. Turning a parameter knob
clockwise will increase the value of a parameter, turning anti-clockwise will decrease it. Turning a
knob rapidly will cause the action to 'accelerate', so the value changes more rapidly.
Store Button
The unit has 45 preset locations. To store a preset in a location, press the store button and use the
parameter knobs to select the preset location and name the preset. Pressing the store button again
completes the task. Pressing any button other than store during the process cancels the procedure.

Front Panel
1 Input Signal Indicators
A set of three pairs of LEDs indicate signal present, +4dBu and input clip for each channel. The signal
present LEDs operate at approximately 40 dBu, giving a useful indication of even relatively low input
signal levels. The +4 dBu LEDs are intended to show nominal operating level and can also be useful
for setting system gain structure. Clip LEDs warn the user of input overload and operate at +19 dBu.
2 Preset Store and Recall
These controls provide access to the 45 presets stored within the device. Pressing the store button
allows the user to name a preset and choose which memory location it will be held in. Pressing store
button again completes the process. The Recall function operates in a similar way, pressing the recall
button allows the user to select which preset they require, pressing the button for a second time, then
confirming, recalls the new DSP settings.
Note that presets cannot be stored or recalled when Secure mode is activated.
3 Channel Select Buttons
The currently selected channel is displayed on the top left hand corner of the LCD. Pressing the
channel buttons scrolls through the available input and output channels and finally through the utility
functions and back to the default screen. If operating a stereo linked preset, the channel name will
indicate the channel pairing. For example 'A+B' means both input A and B parameters. The name of
the output will be shown briefly at the top of the display when stepping onto an output.
4 Edit Select Buttons
The currently selected edit parameter page is displayed on the bottom left corner of the LCD.
Pressing the edit select buttons moves through the available parameters for the current input or
output.
5 Text Display
Preset, channel, parameter and status information is shown on the 2x 24-character text display. In
most screens the currently selected channel is displayed on the upper line and the edit parameter on
the lower line. To simplify the display and enhance security, some parameters or parameter pages
are omitted when not relevant.

1 Power Inlet
The OHM CRED series unit should be connected to a suitable mains electricity supply using the cable
supplied. The processor has a switch mode power supply that is capable of operating with a nominal
mains voltage of 85V to 240V, 50/60Hz without re-configuration.
2 Network Expansion Port
This allows for a network card to be fitted.
3 Audio Input Connectors
All audio connections are fully balanced and wired pin-1 ground, pin-2 hot & pin-3 cold. The two
inputs have pin-1 connected directly to the chassis and feed the signal processing chains. If an
unbalanced source is used, a connection should be made between the pin-3 'cold' signal and the
4 Audio Output Connectors
The processed outputs are impedance balanced, and wired pin-1 ground, pin-2 hot and pin-3 cold. An
unbalanced input may be driven by connecting pin-3 'cold' signal to the ground connection of the
unbalanced destination input. Note that output pin-1's are ground lifted at audio frequencies but
connected to ground at RF for good EMC performance. The intention being that the amplifiers the
processor is driving should be responsible for the grounding of their input cable shields.
5 Communications Port Connector
A CRED processor may be controlled entirely from another controller, typically a Personal Computer,
running an application that is compliant with the ObCom standard. Connection will normally be made
to the controller via this serial port connector. This port is also used for updating the firmware in the
unit.
Note that the communications port is NOT disabled when the front panel is made secure using the
secure button.

Operation
Starting up
The unit will energise as soon as power is applied to the IEC inlet; there is no power switch. During the
start up process the firmware application model number and version numbers are displayed and the
outputs are muted until the unit has completed its internal checks. Once the start-up routines are
complete and the unit is ready to pass audio. The DSP signal path will be restored to the current
settings when it was last powered down and the audio signal is gradually ramped up to its correct
level.
Selecting a Factory Preset
The CRED series processors have a library of designed to suit a range of OHM
enclosures.
contain some parameters that are fixed and hidden from view; the remainder of the
DSP parameters are available for user manipulation. The number and type of hidden parameters is
dependant on the , typically crossover frequencies, output delay and some EQ's are
hidden; those settings that are a function of the loudspeaker cabinet design and should not require
adjustment for different applications.
To recall a for a particular cabinet or system, press Recall and use the left hand
parameter knob A to scroll through the available factory preset locations (as indicated by a box
symbol after the preset number). Once the appropriate preset has been selected press recall again,
at which point you will be asked to confirm the action by pressing recall for a third time. This is to
guard against accidental recall of Presets.
Factory Presets are locked so they cannot be over-written. The user can, however, store an edited
version of a Factory Preset in any free preset location.

In addition to the the unit has two further ; mono and stereo. These
are stored in locations 1 and 2 respectively, they can be used to develop settings for any
loudspeaker combination and are recalled in the same way as the described above.
These Presets are also locked but the user can name and store their own edited versions in any free
preset location.

A parameter may be adjusted when it is displayed by turning one of the three-parameter knobs. Each
of the three-parameter knobs is associated with a zone on the display. Adjusting the leftmost
parameter knob will change the value of the parameter showing in the leftmost zone of the display
and so on. Turn a knob clockwise to increase the value of a parameter, or anti-clockwise to decrease
it. The knobs are velocity-sensitive so turning a knob rapidly will cause the action to 'accelerate', so
the value changes more rapidly.
Navigation
The DSP parameters are organised by channel. The currently selected channel is shown in the top left
hand corner of the display. You can navigate between the channels by pressing the channel buttons.
Pressing the channel buttons will scroll through the channels, utilities and back to the default screen.
When using a Preset that is stereo linked, the channel selection will reflect this. For example '1&4'
indicates outputs 1 and 4. When navigating onto an output channel, the usage of the output, as
define in the factory preset, will be shown briefly at the top of the screen.
Pressing the edit navigation buttons gives access to the various pages of parameters available for
each channel. The currently selected page is shown in the bottom left hand corner of the display, this
is omitted on some pages where the function is obvious. The screen shows up to three (normally
related) parameters for a given part of the processing functions on a given channel.
The edit buttons allow you to scroll, in either direction, through the different processing pages for a
given Channel. When you go past the last page, you will be returned to the default page.
The channel buttons allow you to scroll, in either direction, through the input and output channels,
whilst trying to maintain the currently viewed processing block. If the channel you scroll to does not
have the currently viewed processing block, the next one will be shown instead.
NB. When the unit powers-up, the settings will be the same as those when the unit was last switched
off.

Stereo / Mono Formats
Stereo / Mono Formats
There is only one 'standard' layout of the processing blocks, but flexible routing and control linking
allows this layout to be adapted to a wide variety of applications.
There are two 'Formats', Mono or Stereo. With the Mono format, all outputs have unique parameter
settings, and all outputs are identical in terms of processing functions and routing capability. This is
the most flexible Format.
Stereo format pairs the inputs and outputs for stereo operation, the parameters of each member of
the pair being identical. The routing of inputs to outputs is fixed. This format is intended for
symmetrical stereo operation, eliminating the need to make identical parameter adjustments for
each channel.

With the exception of HD and Lunaray Systems all settings are based on a 1:1 ratio and for use with
CFU-A3 amplifiers with gain sensitivity set at 1.1v.
Delays are set for “flush fronts”.
Note: Delays are linked so care should be taken to address the system especially in 3 and
4 way systems IE: Saturn and HD when any adjustments are made.
“LUNARAY 1” is set up for a “soft” mid/high sound,
“LUNARAY 2” is set up for a “linear” sound
HD set up is based on 2 stacks each side.
Any room adjustments should be made on the input EQ only.
