Using the 1/4" TRS Input as a “Thru” Connector
Because the XLR connector and the 1/4" TRS
connector are in parallel, you can use the 1/4" TRS jack
as a “Thru” connector to pass the input signal on to
another amplifi er’s input (see Figure below).
In MONO and BRIDGE modes,
INPUT A and INPUT B are connected
together in parallel. This allows you
to use INPUT B as a “Thru” connector
to daisy-chain the input signal to
another amplifi er.
Output Wiring
Use heavy gauge, stranded wire for connecting
speakers to the Speakon outputs jacks. As the
distance between the amplifi er and the speakers
increases, the thickness of the wire should also
increase. Speaker wire has resistance, and when
electricity passes through a resistor, power is lost. The
thicker the wire, the less resistance it offers, and the
more power actually gets to the speaker.
The thickness of the wire is rated in gauges. Use the
chart at the right to determine the correct gauge of
wire to use according to the distance between the
speakers and the amplifi er, and the impedance of
the load the amplifi er is driving. This ensures that the
power lost across the speaker wire is less than 0.5 dB.
Note: If you use an unbalanced
1/4" TS cable to daisy-chain the TRS
input jack to another amplifi er, you
will unbalance the XLR input on the
Juice amplifi er. This negates the
benefi ts associated with balanced
lines and inputs.
