1. MIC input (XLR or jack)
2. LINE input (XLR or jack)
3. LINK outputs (XLR)
4. BASS EQ controls
5. TREBLE EQ controls
6. VOLUME controls
7. SIGNAL/CLIP indicators
Operation
Connect the CV-series active speaker unit to the mains using the appropriate mains IEC lead
supplied.
Combined 6.3mm jack or XLR (balanced or unbalanced) inputs are provided to connect either
a microphone, line input or both. Tone shaping is available by adjusting the BASS and TREBLE
controls and each input is governed by a VOLUME rotary control.
An XLR LINK output is provided from each input channel to link onto further active speakers.
Connect the required inputs and outputs and with the VOLUME controls down (anti-clockwise),
turn the POWER switch on. BASS and TREBLE controls should remain pointing vertically (12-oclock position). Gradually increase the volume and check that the signal is present by seeing
the SIGNAL/CLIP indicator light up green and that the sound is being delivered from the
speaker. Increase VOLUME to the required level.
When the signal level is too high, the SIGNAL/CLIP indicator will light red and the output may
sound distorted. In this eventuality, reduce the VOLUME to the point where the indicator only
lights red very briefly on the loudest peaks of the input signal(s).
Ensure that volume controls are turned down before powering down and unplug from the
mains when not in use for long periods.
