3] Installation
Installation into the 500 Series rack is relatively straight
forward. Ensure the rack is completely powered down
before attempting installation to prevent damage to
the module.
Choose the position in the rack to which you will install
the module. Note that the Essence has two edge
connectors that must mate with the rack connectors.
Slide the unit in so that the gold plated edge
connectors of the module align with the matching
connectors in the rack. A gentle push and the module
should slide home into the rack connectors.
Please avoid touching the gold plated edge connector
of the module to prevent sweat from tarnishing the gold
plate and thereby avoiding any connection reliability
problems in the future.
Attach the Essence front panel to the front of the rack
with screws supplied by your rack manufacturer. This is
important for mechanical rigidity. Do not over tighten
these screws to avoid stripping out the threads.
!! Important Note !!
The Essence consumes 2 slots within the 500 rack. If the
unit is installed into slot 1 and 2 of the rack, the main
audio input and output is accessed via the XLR
connectors associated with slot 1. The XLR connectors
- 5 -
associated with slot 2 can be used to insert another
device (an equalizer for example) into the side chain
path of the compressor. The male XLR is the send to
the external device, the female is the return from the
device. More on side chain insertion later in this
manual.
Once you have the module in place, apply power, test
that everything is working OK, and most importantly,
enjoy!
4] Controls and Indicators
Please refer to the picture on the following page.
[1] GAIN
This rotary control varies the output gain of the
Essence from 0 to +15dB and makes up for the loss
associated with compression. This control is bypassed
when using the S/C MON function (3).
[2] BYPASS
This switch completely removes the
compressor from the audio path connecting the input
to the output directly. The compressor is bypassed in the
I
(in) position and active in the O (out) position.
[3] S/C MON
S/C is the abbreviation for Side Chain. This
control allows you to monitor (via the Essence main
output) the audio feeding into the compressor control
circuitry. This is useful if you have an equaliser inserted
in the S/C path or are using the onboard S/C EQ.
