The Line position can be used for recording directly into a tape machine as well as going directly to the studio board. An
external power amplifier with a balanced input can be driven in the Line mode.
Pin out for the XLR connector are as follows: Pin 1= ground, Pin 2= Pin 3=
ACTIVE ELECTRONIC CROSSOVER
HIGH AND LOW OUT JACKS
The Crossover High and Low out jacks have been provided for bi-amping capabilities. Present at the Low jack are all
frequencies below the point set by the Frequency Control. Present at the High jack are all frequencies above the point set
by the crossover or Frequency Control. All patching from these jacks should be done with shielded cable.
FREQUENCY CONTROL
The Frequency Control sets the crossover point or dividing point of the High and Low jacks. For example, if the Frequency
Control is set at about mid-position or 50OHz, all frequencies below 50OHz will appear at the L<)w output jack and all
frequencies above 50OHz will appear at the High output jack. Crossover slope is 12dB per octave.
USING THE INTERNAL POWER AMP FOR BI-AMPING
The internal power amp in the PB-200 may be used for amplifying either the low or high frequencies in a bi-amp system.
As a general rule., the bottom end or low frequencies should have at least twice the power that the high frequencies have.
So.,if your slave power amp has a rating of 100 watts, use it for the highs and the PB-200 for the lows. Once you have
selected the use for the PB-200,-run a patch cord from either the high or low out jack to the Power Amp In jack. This
automatically stops any other signals from going to the internal power amplifier. The level or volume of,the internal power
amp is still controlled by the Master Volume on the front panel. This allows the user to compensate for sensitivity
differences in the two power amps being used.
EQ FOOTSWITCH
Insertion of a footswitch into this jack allows the user to turn on or off the Variable Graphic Equalizer. With no,footswitch
plugged in, the Variable Graphic Equalizer is always on.
PRE AMP OUT/POIVER AMP IN JACKS
The Pre Amp Out jack is an unbalanced line out and can drive a slave power amplifier or-can be used for a patch to a
mixer, etc. The Pre Amp Out jack is before the Master Volume and its level is controlled by the Gain Control on the front
panel. The Power Amp In jack is provided for bi-amping capabilities (see Active Electronic Crossover section) and for using
the internal power amplifier by itself. Insertion of a plug into this jack automatically disconnects the preamp signal that
normally is present. The volume of the power amp is still controlled by the Master Volume control on the front panel.
USING THE PRE AMP OUT/POWER AMP IN JACKS AS AN EFFECTS LOOP
These jacks can be used as a line level effects loop. When used in this manner, the pre amp out jack becomes the "To" and
the power amp in jack becomes the "From" effects jack. Refer to "Effects Loop" for further information.
SPEAKER JACKS
Two speaker jacks are provided for hooking up your speakers. Always use good quality cable for your speakers as it is the
final link between the electronics and your speakers. It should be at least made of 18 gauge wire or heavier (the lower the
gauge, the heavier the wire) and DO NOT use shielded cable such as that used for your instrument. Minimum load for the
power amp is 4 ohms. This means that you can use one 4 ohm cabinet, two 8 ohm cabinets, or four 16 ohm enclosures.
SPEAKER FUSE
The Speaker Fuse is provided to protect your speakers in- the unlikely event of a power amp failure. Size and rating of the
fuse is 3AG, 6AMP, FAST-BLOW. Do not defeat the purpose of this feature by using a higher rated fuse.
The speaker fuse can also open if there is a fault in the speaker cable or the-speakers themselves. Therefore, it is always
wise to carry extra fuses at all times.
LINE OR MAINS FUSE
The size and rating of the Line fuse is 3AG, 4Amp, SLO-BLO. NEVER replace this fuse with one of a higher rating as it can
only cause more damage to your unit and can void your warranty.
A/C CONVENIENCE OUTLET
The A/C Convenience Outlet is provided to provide AC power to another piece of equipment. Check the power rating to
make sure that it is less than the rating written on the back panel of the PB-200.
