TYPICAL BRIDGED SETUP
CONNECTING THE SYSTEM
The following diagrams illustrate typical connections. Although these illustrations show
XLR’s for inputs and 1/4” plugs for outputs, a variety of alternative connectors are available.
For most stage setups, mono (not stereo) is recomended. The reason for this is the audi-
ence on the left will not hear the same program material the audience on the right hears if
the program is done in true stereo.
INPUT CONNECTIONS
The preferred method of connecting input signals is with balanced XLR’s (two conductors
plus a shield wire, such as Carvin professional XLR cables). Balanced input signals provide
the highest gain and best noise rejection. 1/4” stereo cables are also capable of providing
balanced input by using a stereo plug (tip-positive, ring-negative & sleeve-ground). Not all
sources provide balanced outputs. If this is the case, standard 1/4” input cables work fine
with cable lengths under 25 feet (single conductor plus shield) providing there is no ground
loop in the system.

SPEAKER CONNECTIONS
There are two 1/4” speaker jacks available for speaker connections (one for each channel).
Additionally, there are two pairs of binding posts that not only allow for high current con-
nections to speakers but are also used for “bridging” the amps output (see rear panel sec-
tion 14 & 15). Use heavy gauge wire for all speaker connections (no lighter than 16 gauge
up to 50’, Carvin’s PH50). Caution: Never use shielded cable (microphone or instrument
input cable) to connect speakers. These cables will not handle the required current and may
cause your amplifier to oscilate because of the internal shield.
