6. MONITOR OUT JACK
This 1/4" phone jack delivers the signal from the monitor mixing bus to feed external monitor speaker
system driven by external amplifier.
This jacks have a output level of +4dB.
7. PHONES CONTROL
This control adjusts the level of the stereo signal delivered from the PHONES jack.
8. PHONES JACK
This jack delivers the main program signal to a pair of 40Ω stereo monitor headphones. The volume of the
output signal is adjusted by the PHONES control.
1. POWER SWITCH
This switch turns the CA-6220/8220's power supply on
and off. The power LED will light when the power is on.
2. PROTECT LED
1
Indicates when protection circuit turns on. When the
amplifier outputs have the state of fault in the circuit
protection LED indicator illuminate red color.
3. PHANTOM ON/OFF SWITCH AND LED INDICATOR
The PHANTOM ON/OFF switch turns the phantom
2
power feature on and off. When turned on, this function
supplies +48V power to the positive and negative ter-
minals of the balanced XLR connector via 6.8kΩ current-
3
limiting/isolation resistors for use by phantom powered
condenser microphones.
The PHANTOM LED indicator lights when phantom power
is on.
4. EFFECT RETURN CONTROLS
These controls adjust the level of the signals that are
4
received at the corresponding EFFECT RETURN jacks (or
from the internal digital signal processor, when the DSP is
used in place of external input to the EFFECT RETURN 2
5
jack).RETURN control adjust the level of the signal that is
mixed into main program on the master mixing bus.
RETURN 2 TO MONITOR control sets the level of the signal
that is mixed into the Monitor bus, where it is mixed with
6
other signals for output by the MONITOR OUT jack.
5. MONITOR OUTPUT LEVEL CONTROL
7 This control adjusts the overall output levels of the monitor
mix that are set up using the MONITOR control of each
input channel. The same monitor mix signal is sent to the
8 MONITOR OUT jack.
This control should be used to optimally match the monitor
mix output levels to the input sensitivity of the power ampli-
fiers used.
