The Rear Panel - Crate CPB150 User Manual

The Rear Panel:

9. SPEAKER OUTPUTS: Use these jacks to
connect the amplifier to your speaker cabi-
nets. Observe the wattage and impedance rat-
ings adjacent to each jack. The Mono output is
to be used when the Bridge Mono switch (#10)
is depressed. The Right and Left jacks are to
be used when running the amplifier in the
stereo mode.
NOTE: Do not operate the unit with stereo
cabinets that have a common shield.
Operating the unit with this type of cabinet
will activate the protection circuitry caus-
ing the unit to shut down.
10. BRIDGE MONO: This switch, when
depressed, sends the left channel to both
power amplifiers and their outputs to the Mono
Speaker Output jack (#9). When this switch is
in the out position, the amplifier is in the stereo
mode and the left and right signals are sent to
the Left and Right Speaker Output jacks (#9).
11. LEVEL: Use this control to adjust the level
of the signal at the Line Out jack (#12).
12. LINE OUT: Use this balanced XLR jack to
send a line level signal to another amplifier, the
house mixing board, or a recording console.
(The signal at the Line Out jack is enhanced
by the speaker simulator circuitry for superior
sound.)

13. CD INPUT: Use these RCA jacks to con-
nect the outputs of a CD (or MP3) player to the
amplifier. The level of the signal into these
jacks must be controlled by the source.
14. LINE IN RIGHT / LEFT/MONO / EFFECTS
LOOP SND/RTN: Use these jacks to perform
the following: (1) Send a line level signal into
the amplifier for processing – for stereo sig-
nals, use both jacks; for a mono signal, use the
"Left/Mono" jack. (2) Connect an external
effects device to the amplifier by means of a
1/4" T/R/S Y-cord inserted into the Effects Loop
Snd/Rtn jack. (See page 6 for additional infor-
mation.) These jacks are post eq, post Level.
15. POWER: Use this switch to turn the ampli-
fier on (top of the switch depressed) and off
(bottom of the switch depressed).
16. AC LINE IN: Connect the AC power cord
securely into this jack. The grounded power
cord should only be plugged into a grounded
power outlet that meets all applicable electri-
cal codes and is compatible with the voltage,
power and frequency requirements stated on
the rear panel. Do not attempt to defeat the
safety ground connection!
