Make sure the switch is set either to full left or full right to avoid an intermittent condition.
XLR PAD CONTROL
This control sets the level present at the Balanced (XLR) Output. Turning the control counter-clockwise
reduces the overall level, while turning the control clockwise boosts the overall level. It should be noted
that turning the control fully counter-clockwise to "MIN" does not fully defeat the signal. This is normal, as
the XLR Pad is designed to provide a range of usable levels to be sent to a front-of-house or studio mixing
console.
XLR GROUND/LIFT SWITCH
Sometimes connecting to certain mixing boards or studio consoles with non-standard XLR wiring can
cause a ground loop. Your Baby Baby Blue has a switch—located on the XLR Pad Control knob—for lifting
the ground on the Balanced (XLR) Output. (It affects no other outputs.) Pulling the knob out or pushing it
back in will change the mode of operation. When the knob is in the "in" position (default setting from the
factory), ground is on Pin 1 of the Balanced Output jack as normal. When the knob is pulled to the "out"
position, the ground is lifted from Pin 1 of this output. If a persistent hum exists after trying both positions
of the ground lift, there is probably:
1. A bad cable or connection somewhere between your Balanced Output jack and the snake leading to
the mixing console
2. A dirty or miswired A/C socket
3. Mis-wired or poorly wired A/C in the building
4. fluorescent lighting directly above you or in close proximity (especially when using single-coil pickups)
5. A cell phone in your right pocket that's interacting with the electronics in your bass (don't laugh, this
actually happens!)
But, in the case of a true ground loop, this switch can often times solve the problem.
TUNER OUT JACK
The Tuner Out function—marked "To Tuner Input" on the rear of your Baby Baby Blue—allows the user to
plug their instrument tuner into this jack and "tune up" without having to unplug and go back and forth
from amp to tuner. This feature is totally isolated from the rest of the preamp and will function regardless
of the settings on the front panel. Being isolated on a side chain avoids loading down of the instrument,
which can cause a loss in dynamic range.
To use this feature, connect a shielded patch cord from the "To Tuner Input" jack on your Baby Baby Blue
to the input jack on your tuner. Turn the amplifier on and you're ready to go. If you do not wish to monitor
your sound during the tuning process, you may turn down the Master Volume.
LINE OUT JACK
This jack provides an audio output located later in the signal chain than the Effects Send jack. This signal
is post-EQ and post-effects loop, but still before (pre) the Master Volume control. You should use this jack
when using an effects device in the effects loop and wish to achieve:
1. A line level output for use in conjunction with an additional power amp or powered extension speaker
cabinet
2. An unbalanced output suitable for recording or live mixing board purposes
