CARVIN XC3000 - BI-AMPLIFYING WITH THE XC3000; MONO BI-AMP CONFIGURATION; STEREO BI-AMP CONFIGURATION

MONO BI-AMPING
If your system requires only mono bi-amplification, you will utilize only one side of the XC3000 “CHANNEL ONE”.
Simply plug your full range frequency source into the “CHANNEL ONE” 1/4 “ PHONE or XLR input connector at the
rear panel of the XC3000. Then connect the “LOW OUT” and “HIGH OUT” XLR jacks to the input of your power ampli-
fier. Note: If a stereo amplifier is used, you will male your connections to either side “Channel 1” or “Channel 2” of
the amplifier as respectively used in connection to the horns and woofers of your sound system.
Depress the “2 WAY / 3 WAY” selector switch on the front panel of the XC3000 so that the unit will operate in BI-
Amp mode. Now set the “GAIN” of “CHANNEL ONE” to “0” dB (center of rotation). Set the “LOW LEVEL” and “HIGH
LEVEL” controls to -∞ (off position). Adjust the “LOW / HIGH” frequency selector knob to the approximate desired
crossover point. If the desired crossover frequency is above 1kHz, depress the “x10” multiplier switch.
Now power up your system. Note: your power amplifiers should be the last piece of equipment to turn on, and the
first piece to turn off when applying and removing power from a sound system. Send a typical full range signal into
the XC3000 and slowly bring up the “LOW LEVEL” control until the desired volume level is realized. Then bring up the
“HIGH LEVEL” control until the highs and lows sound well balanced. Now you can fine tune the crossover frequency by
adjusting the “LOW / HIGH” frequency selector knob.
STEREO BI-AMPING
Stereo bi-amplification works in exactly the same manner as in mono bi-amping except that you have two full range
input sources (stereo inputs). Make one connection from the stereo source to one side (CHANNEL ONE) of the XC3000
and connect the other source to (CHANNEL TWO) of the XC3000. The crossover frequency separation will work in
the exact same manner as in mono biamplification, however, “CHANNEL ONE” will bi-amplify one side of your stereo
system. Note: In stereo biamplification you will have to utilize four separate power amplifiers or two stereo ampli-
fiers. This will be required to amplify both low pass (woofer) and high pass (horn) signals to your stereo speaker
array. As a general rule, the high pass amplifiers of your stereo speaker array only have to be 1 / 3 the wattage of
the low pass amplifiers due to the higher efficiency and lower power consumption of the horns. Be sure to adjust the
gain controls and level controls for each channel so that the “PEAK” indicator LED does not flash. Also be careful to
note the position of the (1X / 10X) switch per channel, and the respective frequency crossover point in order not to
deliver harmful low frequencies to the horn arrays.
