CONTROLS & CONNECTIONS

2.4 Gain

•

Gain

When compressing a signal, Gain reduction usually results in an overall reduction of

level. The Gain control allows you to restore the loss in level which occurs due to the

amount of compression used. (like readjusting the volume.)

2.5 Bypass & Link

•

Bypass

Activating the Bypass effectively removes all processing being performed by your ACP-

88 and returns the signal to unity gain. You should use Bypass often when setting up

your ACP-88 to compare the 'before and after' results of the signal processing effecting

your audio signal. Bypass affects both the Gate and the Compressor. When

Bypassed, the Link function is interrupted for that channel and essentially breaks the

link in your linking 'chain'.

•

Link

When the Link button is engaged (pushed in) the LED labeled LINK becomes active

indicating this channel has become the slave of the channel to its immediate left (The

Link LED is only active when the signal is present in the Linked channel). All of the

controls for the Linked channel become disabled and metering occurs by way of the

Gain reduction meter of the channel to the left (Exception: the LED meter of the

Slaved channel is still useful to indicate the presence or lack of signal). Essentially, the

left channel is still the Master and the channel with the Link button pushed in is the

Slave channel in a stereo linked pair. If multiple Link buttons are pushed in, then the

channel farthest to the left of the multiple Linked channels (without its link button pushed

in) becomes the Master for the multiple Linked channels. In this case, all metering

should be referred to the Master channel's meter.

*IMPORTANT: When a channel is Linked (link button pushed in), all of it's controls

are inactive. The Link LED is active. Also, even though the meters on the Linked

channel are still operational (presence or lack of signal), all metering should be

referred to the Master channel's meter for the Gain reduction level of the Linked

channels!
