probably overdriving your headphones and could ruin them. To practice silently, set the
on the back panel to the "Off" position. Any impedance stereo headphones will work, however, optimum imped-
ance is 75 ohms. Do NOT use mono headphones as they will short out a channel.
SPEAKER ON/OFF SWITCH
In the TOP position, labeled "On," both the woofer and super tweeter in the speaker system are activated. The
tweeter level can be separately controlled and/or eliminated by using the Tweeter Attenuator (described below in
"Crossover Panel Features").
The BOTTOM position, labeled "OFF" disconnects the signal going to the internal speakers and extension speaker
jack. Use this position when listening through headphones only or for silent tuning (refer to "Tuner Out" section).
The Stereo Headphones jack is always active regardless of the position of this switch.
INTERNAL CABINET JACK/PLUG
This specially-sized jack/plug assembly (in the black plastic housing) runs the signal from the amplifier to the
California Blonde's internal speakers. It should NOT be unplugged unless the chassis needs to be removed from
the unit, which should ONLY be done by a qualified technician.
EFFECTS LOOP
Separate and independent effects loops are provided for both the Instrument and Mic/Aux channels. They are
located POST EQ and PRE Reverb & Master Volume in the signal path. The level appearing at the Send jacks
is controlled by the Gain functions on the front panel. If you are getting too hot a signal at the input of your
effects unit, reduce the level of the applicable
similar overall volume levels. By using the
formance should be easily obtainable with any effects device.
Since the effects loops are on a side chain, their use should greatly reduce noise generated by effects devices (as
compared to in-line effects loops). Additional features of this type of loop can be found below under the Receive
jack section.
SEND
Run a shielded patch cable from the Send jack to the input of your effects device. This jack may be used as an
additional line level output, in which case its level is determined by the setting of the
RECEIVE
Run a shielded patch cable from the output of your effects device to the Receive jack.
One unique feature of the Receive jack is the ability to practice along with pre-recorded music. Insert a sound
source into the Receive jack (make sure it's a mono signal). Use the
the recorded music with your instrument's level. The combined signal will be heard through the internal speakers
or your headphones. The Send jack is not used.
NOTE: Inserting a plug into the Receive jack activates the Effects Blend control by receiving a
"command" through the ground created. Therefore, only a mono (2-conductor) phone plug should
be used.
If you are not getting any "effect" through the speakers, check the position of the appropriate Effects Blend con-
trol on the front panel.
BALANCED XLR LINE OUT
Being a "line" out, the signal appearing here is similar to that heard through the speaker system. All of the con-
trols on the front panel, except the
To use this feature, run an XLR cable from the Balanced Line out to the input of a mixing console, tape machine,
etc. This output is also suitable for sending a signal to a house mixer in live situations.
Wiring for the XLR connector is American standard: Pin 1= ground, Pin 2= +, Pin 3= – (minus)
STEREO OPERATION
Complete stereo operation can be achieved using the following procedure:
First, you will need an external power amp and speaker cabinet (powered "slave" enclosures are ideal for this sit-
