OPERATION

Front panel
Channel A and B are identical.
1. POWER Switch
Turns power to the crossover on and off. Be sure to power-up before your power amplifier is turned on to
avoid loud transients which could damage your speakers or annoy your audience.
2. THRESHOLD Control
This control sets the threshold point for the compression of the input signal between -40 dBu and + 22 dBu
and thus prevents distortion and gives good protection to your amplifier and speakers. Rotating clockwise
raises the threshold, thus squeezing signals at a higher level and reducing the amount of compression or
limiting.
3. LIMITER Selector
This switch activates the limiter function.
4. INPUT LEVEL Control
To adjust the input level from - to +6 dB.
∞
5. LOW CUT Selector
This switch activates the highpassfilter and allows you to cut down unwanted low frequencies.
With the Low Cut-function, you can attenuate all signals below 30 Hz. Please keep this button pressed if you
do not need these extremely low frequencies at any rate. If your speaker-system does not support these
frequencies, there is danger of speaker damage!
6. PHASE Control
This control reverses the polarity of the Low output.
7. LOW OUTPUT LEVEL Control
Controls the output level of the Low band from - to +12 dB.
