Power Switch - SWR Baby Blue II Owner's Manual

FAILED DUE TO CONTINUOUS CLIPPING OF THE POWER AMP WILL NOT BE COVERED UNDER
WARRANTY! Occasional clipping of the power amp (no more than every fourth or fifth note) will not harm the
internal speakers. Turning down the Master Volume will correct this situation.

POWER SWITCH

Pressing the Power Switch to the ON position activates the Baby Blue's electronics as indicated by the red
LED lighting.

BALANCED XLR OUT
The Balanced XLR Out is a true balanced output whose level is set by the XLR Pad directly to the left. The
signal appearing at the XLR jack is governed by the position of the Line/Direct switch directly below the jack.
In the LINE position, all front panel controls are functional and the signal is essentially the same that is being
sent to the internal power amplifier. If you are using an effect, this will also appear mixed in the signal when
you are in the LINE mode. In the DIRECT position, the Balanced out becomes an active TUBE direct box. No
front panel controls are functional and once again, the level is adjusted by the XLR Pad.
When using the Balanced Out for recording, optimum results can be achieved by DRIVING THE TAPE DECK
DIRECT. Of course, if this is not possible, the Baby Blue will work in any other situation. Whenever possible,
use the XLR Pad to adjust working levels. The use of input pads on consoles can deteriorate sound quality.
A ground lift is built into the XLR Pad control. To lift (remove) the ground connection, pull the knob outward
until it clicks.
If a persistent hum exists after trying both positions of the ground lift function, there is probably a problem
with the AC wiring or just a dirty AC line. If this is the case, we suggest using an isolation transformer
between the Baby Blue and the wall socket.
Wiring for the XLR connector is as follows: Pin 1 = ground, Pin 2 = +, Pin 3 = - (American Standard)
XLR PAD
The XLR Pad adjusts the level (volume) appearing at the XLR connector. Volume increases as the control is
turned clockwise. The XLR Pad has a built in ground lift for the balanced out. Pulling the knob outward
disconnects the ground (pin 1).
If you are in the LINE position and change the Gain control on the front panel, the level will also change at
the balanced output. You may readjust the record level if necessary with the XLR Pad without affecting any
other function.
LINE/DIRECT SWITCH
In the Line position, the signal going to the power amp also appears at the Balanced out jack and all front
panel controls are functional. In the Direct position, a direct signal from the input jacks appears at the XLR
connector. For further information, see "Balanced XLR Out" above. When using this switch, make sure it is all
the way to the left or right and not in a "half way" position.
NOTE: Turn off transients appear at the record outs when the amplifier is turned off. It is recommended
that equipment that is being used in conjunction with the record outs be turned down, off, or disconnected
BEFORE the Baby Blue is turned off.
LINE OUT
The Line Out jack is located POST EQ and PRE Master Volume in the block diagram. This function will allow
