Compressor Dual Channel
Dynamic Enhancer Section (Operation)
Dynamic enhancement allows for selective replacement of high-end loss accrued through use of compression. As the sig-
nal level rises towards the threshold point where compression will occur, high frequency enhancement is added at the same
degree to which the input signal is compressed. The Compressor/Limiter accurately tracks the amount of compression in
order to compensate with the same amount of dynamic enhancement, even if there are heavy signal variations. When there
is no compression, the signal is not enhanced. For more versatility, a PROCESS control allows you to control the available
amount of dynamic enhancement.
12. PROCESS CONTROL:
The PROCESS control sets the available amount of enhancement on a relative scale between off and 6. Dynamic enhance-
ment allows you to replenish any high frequencies lost through the compression process for absolutely natural sounding
dynamics control. Enhancement is only added when compression is taking place.
13. MODE (STEREOIMONO) Switch:
The MODE switch can be used to select either Stereo of Mono operation as marked. In stereo mode, both channels opera-
te independently and all the separate channel controls are functional for both channels. In the MONO (depressed button)
mode, the controls of Channel 1 take over all the functions of Channel 2 with the exception of the IN/OUT and the PRO-
CESS control of the Dynamic Compressor Limiter.
14. INPUTS:
The COMPRESSOR is equipped with both 1/4" (6.3mm) TRS and XLR audio input jacks. These can be used for either balan-
ced or unbalanced operation as follows:
Unbalanced use of mono 1/4" plugs:
Tip = Signal, Sleeve = Ground I Shield.
Balanced use of TRS stereo 1/4" plugs:
Tip = hot (+), Ring = cold (-), Sleeve = Ground / Shield.
Balanced use with XLR connectors:
1 = Ground I Shield, 2 = hot (+), 3 = cold (-).
15. 0UTPUTS:
The audio outputs of the COMPRESSOR are XLR connectors.
Balanced XLR connectors: 1 = Ground I Shield, 2 = hot (+), 3 = cold (-).
16. OPERATING LEVEL Switch:
With the OPERATING LEVEL switch, you can select either of 2 operating levels: the - 10 dBV home recording level or the
+4 dBu professional studio level. The level meters are referenced automatically to the selected level so that optimal ope-
rating range of the meters will always be ensured.
17. FUSE HOLDER:
The IEC power socket has an integral fuse holder that takes a 20mm fuse. Always replace a blown fuse with the same type
as specified on the rear of the unit.
18.POWER CONNECTION:
A standard IEC AC power socket for connecting to the main AC supply with the power cord supplied.
19. AC VOLTAGE SELECTOR Switch:
Use the VOLTAGE SELECTOR Switch to set the unit for the proper voltage for your area, 115 VAC/60 Hz or 230 VAC/50 Hz.
(Note: Selecting the wrong voltage can damage the unit.)
20. DETECTOR LOOP INSERT:
This 1/4" TRS jack can be used as insert point to enable the unit to be controlled externally to operate frequency consci-
ous via an equalizer. You can use the connector as a pure input (mono jack connector) or as an insert (stereo jack connec-
tor). In this case, use a special insert adapter cable, which splits up one stereo into two mono jack connectors. The ring of
the DETECTOR LOOP connector carries the unit's output signal and the tip receives the processed signal from an external
unit.
