gAIN STRUCTURE SETUP fOR ACTIvE SPEAkERS
Optimizing gain structure is an important step in minimizing noise and
preventing signal overload (clipping). There are three level controls on
the panel of active CLR speakers. After connecting all the devices in your
signal chain and powering up (remember CLR last on, first off), follow the
procedure below to insure optimal gain structure.
1. S et the Master and both Input level controls to their lowest
1
(CCW) settings.
2. I f you will be using two input signals, perform this step with the one
2
you expect to be louder. (Note: You will hear little or no sound during
this step.) Apply the hottest (loudest) signal you expect to generate.
Increase the Input level control for that channel until you see the LED
adjacent to that input connector light up. Turn down the level until the
LED goes out and never lights.
3. A djust the Master level for the desired volume and the second Input
3
level (if used) for the desired mix. There is no need to adjust the
Input levels beyond this point. The amp has the ability to reach its
maximum output level with the input level set as prescribed above.
Overdriving the input by setting the input level too high will result
in audible clipping.
PASSIvE CAb AND WEDgE OPERATINg INSTRUCTIONS
Passive CLRs are equipped with two combo connectors (Neutrik Speakon
and 1/4" jack). These connectors are wired in parallel and are intended
to enable the user to "daisy chain" a second CLR to a single power
amplifier. Keep in mind that the combined impedance of two CLRs in
this configuration is 4 ohms and make certain that the power amplifier
is rated to drive this impedance. Caution: under no circumstances should
the additional connector ever be connected to a second power amplifier.
Doing so could result in damage to one or both power amplifiers and to
the speaker(s).
