UICk Start
1. Install the processor into the rack.
2 . Connect AC power to the unit, and turn on the power.
3. Connect the analogue and / or digital audio inputs.
4 . Select the analogue or digital input as the source of the processing with the 'INPUT SELECTION' parameter
which can be found in the 'INPUT' menu. Apply audio and observe the input meters. For analogue inputs, adjust
the 'INPUT’ menus 'INPUT LEVEL CONTROL' so that the input meters do not clip. We recommend setting the
mixing board or audio source to full level output (even clipping) prior to adjusting this control. This ensures that
the processor's A/D converter will not clip under any conditions.

USE
:
5 . Select the pre-emphasis setting for your region (input menu). 75 µs for USA and 50 µs for Europe.
6 . Connect the audio outputs as required and set the output level and de-emphasis settings for the analogue and
digital outputs to match any external links, stereo encoders, or transmitters that require left and right audio inputs
or an AES/EBU input. Make sure the output mode is set to FM for the output in question.
7 . If you are using the MPX Output (preferred), navigate to the ‘STEREO’ menu and adjust the ‘MPX OUTPUT
LEVEL’ to match the transmitter (or link device) that follows the processor. Adjust for 100% modulation with
audio.
8 . Select a factory preset (see Managing presets).

5 . Set the pre-emphasis setting to OFF from the input menu.
6 . Connect the audio outputs as required and set the de-emphasis for the analogue and digital outputs to OFF,
MODE to DR and set the output levels for the analogue and digital outputs to match the equipment that the proc-
essor is connected to.
7 . Select a factory preset (see Managing presets).
8 . Navigate to the look-ahead menu and adjust the SHELF EQ control to suit. This sets the brightness of the DR
outputs sound.

6 . Connect the audio outputs as required and set the de-emphasis for the analogue and digital outputs to OFF,
MODE to DR and set the output levels for the analogue and/or digital outputs to match the DR equipment that
the processor is connected to (EG: codec/computer).
7 . If you are using the MPX Output, (preferred) navigate to the ‘STEREO’ menu and adjust the MPX ‘LEVEL’
Output to match the transmitter (or link device) that follows the processor. If one of the analogue or digital out-
puts needs to feed another piece of equipment that cant take a composite MPX input then make sure you select
FM mode for that output with the appropriate de-emphasis setting to match the corresponding piece of a equip-
ment in the FM chain.
8 . Select a factory preset (see Managing presets).
9 . Navigate to the look-ahead menu and adjust the SHELF EQ control to suit. This sets the brightness of the DR
outputs sound.
NOTE: The front panel headphone jack connects to the analogue outputs so the sound may be excessively
bright if pre-emphasis is engaged and de-emphasis on the analogue outputs is set to off.
