Frequently Asked Questions - CA120HZ Ecler
What is the CA120HZ used for?
The CA120HZ is a professional audio receiver with an integrated crossover, ideal for powering passive subwoofers and full-range speakers in sound reinforcement systems.
What is the power output of the CA120HZ?
It delivers 2 x 120 W RMS into 8 ohms, or 2 x 200 W RMS into 4 ohms.
How do I connect a subwoofer to the CA120HZ?
Use the XLR or RCA input for the signal, then use the high-pass output (if available) for satellite speakers and the low-pass output for the subwoofer.
Can I bridge the CA120HZ for more power?
No, the CA120HZ is not bridgeable. It operates in stereo mode only.
What crossover frequencies are available?
The crossover frequency is adjustable from 20 Hz to 300 Hz via a rear panel potentiometer. The slope is typically 24 dB/octave.
How do I set the gain correctly?
Turn the input level controls fully counterclockwise, then gradually increase while playing audio until the desired level is reached without clipping (the Clip LED should not light continuously).
Does the CA120HZ have a low-cut filter?
Yes, it has a switchable low-cut filter (infrasonic filter) at 30 Hz to protect subwoofers from subsonic frequencies.
What should I do if the unit overheats?
Check that the fan is not blocked and that the ventilation slots are clear. Reduce the signal level or lower the ambient temperature. If the problem persists, contact service.
Can I use the CA120HZ with 70V/100V lines?
No, it is designed for low-impedance speakers (4-8 ohms) and is not suitable for constant-voltage systems without an external transformer.
Where can I download the full manual?
You can download the PDF manual for free from the Ecler website or from notice-facile.com.
