Having connected signal inputs and outputs as required, set the unit as follows-

Threshold, Ratio, Attack, Release

Output Gain

Display Switch

Output Switch

Peak Limit

Stereo Link

Display

Expander

Adjust input signal level on preceding equipment to show 0 dB on display, peaking

to +2.

Change output switch to 'norm' and display switch to GR. Adjust Threshold, Ratio,

Attack and Release to give the required compression characteristics and read the

gain reduction on the display.

Change output switch to VU and adjust output gain for optimum reading on the

display.

If the Peak Limiter is required, adjust output gain so that the limiter operates on

signal peaks only. It is important to remember that the peak limiter is connected

after the output gain control so care should be taken to avoid 'pushing' the gain

controls for more level, particularly when treating stereo signals.

For stereo operation, switch in the stereo link and set up as above, making sure

that all controls are the same for both channels. GR. displays will show the same

readings, except when excessive peak limiting occurs on either channel.

If ambient noise is 'pumped' up to an unacceptable degree during compression,

change expander switch to 'norm' and adjust the expander threshold so that the

noise is removed. The expander threshold should be set below the compressor

threshold level to avoid interaction.

Set ratio and attenuation to suit the particular application. When used on a final

mix, set threshold as low as possible but above unwanted noise. Ratio should be

1:2 and attenuation at 10 to 20 dB. This will provide a gentle expansion which will

minimise drop out effects during a fade. However, drums would be better with a

1:5 or 1:20 ratio and 20 or 40 dB attenuation using a higher threshold level. For

vocals, set threshold so as to remove breath and headphone noise and set ratio

a 1:2 or 1:5 with attenuation of 20 or 40 dB.

In all cases, attack is automatic and release is controlled by the compressor.

These suggestions are for guidance only. The final adjustments should be made

to suit the particular application and conditions.
