With normal programme level running through the CX335, rotate the Gain control so that

the output level on the Left and Right channel VU meters measures about the same in

Bypass mode as it does with the Compressor operational. Then rotate the Peak Limiter

control to a position where the peak LED only flashes occasionally to capture very high

level peaks for speaker protection. Normally this will be at a level just below the clip level

of the following amplifier with programme passing though the unit at full level.

With this configuration, the louder the input then the more compression will take place. A

distinguishable increase in average overall volume should be noted, although the peak

output level should be slightly lower.

1.02 Hard knee, Fast time constants

This mode of operation will be slightly more noticeable (especially with high Ratio

settings) as the point where compression takes effect is at a definite audio level.

Depress the Hard switch. Set the Threshold to somewhere between 5dB and 8dB

LOWER than your maximum input level. Set the Ratio control at about 5:1 or even higher,

if you require compression of the audio signal, but 20:1 or higher if you require

compression and limiting. The higher the ratio the more audible the compression will be!

Set the Peak Limiter to a position where the pointer reads a similar value to the maximum

audio input. Turn the Gain control so that the output level on the VU meters measures

about the same in Bypass mode as it does with the Compressor operational.

With this configuration, quieter signals should pass through the compressor un-

processed, (no Gain Reduction taking place) but louder input signals above the Threshold

level will have a significant amount of compression (many LEDS lit on the Gain Reduction

meter). The Peak Limit LED will flicker ON more often than would normally be expected,

especially with very percussive tracks at high level. No perceived effect will be noticed

until very high input levels are used, then the CX335 will take control to preserve system

integrity and prolong the life of the audiences' hearing.

1.03 Intelligent Limiter

Due to the programme dependant nature of the compressor section and its split

frequency stereo side chain, the preferred method of limiting is to use the compressor

section with a ratio of infinity to 1.

Depress the Hard switch. Set the Threshold to the level where limiting is to commence.

Set the Ratio control fully clockwise. Set the Peak Limiter to a position where the pointer

reads a similar value to the maximum level permissible before any following amplifiers will

clip. This should be higher than the compressor limiter threshold by several Dbs. Turn the

Gain control so that the output level on the VU meters measures about the same in

Bypass mode as it does with the Compressor operational.

With this configuration, quieter signals will pass through the compressor un-processed,

(no Gain Reduction taking place) but louder input signals above the Threshold level will
