HARDWARE CONTROLS — BACK PANEL
As the knob is turned clockwise, the control will subtract sidechain level from the unit being adjusted, and add sidechain
level to the opposing unit. If there stereo signal going into both units is extremely close in nature already, it is common for
little or no adjustment to be needed. It is good to reference the WA-2A's gain reduction in Stereo Mode to the amount
of gain reduction it performs on the same input material in Stand Alone mode (link cable removed). If the amount of gain
reduction in Stereo Mode is heavier than when in Stand Alone mode (link cable removed), the Stereo Link Adjust can
be used to reduce the sidechain level. Sidechain signal is generated by raising the Peak Reduction control of a given
unit. Normally, on a stereo source, you will want both units to have the same level of Peak Reduction applied, in order
to create a sidechain signal that is summed of equal parts left and right; however, by setting peak reduction only on one
unit, a type of 'ducking' effect can be produced where the two compressors only respond to the sidechain signal of the unit
in which Peak Reduction is applied. In this scenario, one unit would be considered a 'master' unit, with the second unit
following its direction. In other words, both units would only respond to a transient peak received by the master unit. In
a normal stereo situation, there would be no master unit; as the sidechain signal of both units would be equally summed.
In other words, both units would respond evenly to a transient peak that occurred on either the left or the right channel.
Typically, this is ideal for stereo bus use.
4. With a test signal or music running into both units, begin to turn up Peak Reduction both units
until you see gain reduction being displayed on the VU meters. Both meters should normally track
very close to one another, if the meters are calibrated and if Peak Reduction is set identically on both
units. If there is a visible difference in gain reduction, the Stereo Link Adjust control can be used to
compensate for this.
The two units will now operate as a stereo-linked pair. To return units to normal operation, simply
remove the Stereo Link cable and check that the Stereo Link controls for both units have been returned
to the Stand Alone position.
Stereo Link Input Jack
Connect 2 WA-2A units together using this jack, with one shielded TRS (balanced, 3 pin) ¼ inch
patch cable, of no more than two feet in length.
Balanced Output
This connection provides a transformer-coupled, balanced, line level output for the WA-2A via both
XLR and ¼ inch TRS. The outputs are wired in parallel, and it is not recommended to use both
outputs at the same time. For unbalanced operation, short XLR pin 3 to pin 1 on your XLR cable via
a jumper (requires soldering), or simply use an unbalanced (mono) ¼ inch TS patch cable, which
effectively creates the same configuration.
