Using the 1/4" TRS INPUT 1s 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 amplifier’s input (see Figure below).
In MONO and BRIDGE modes, 
INPUT 1 and INPUT 2 are 
connected together in parallel. 
This allows you to use INPUT 2 as a 
“Thru” connector to daisy-chain the 
input signal to another amplifier.
Output Wiring
Use heavy gauge, stranded wire for connecting 
speakers to the Speakon outputs jacks. As the 
distance between the amplifier 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 amplifier, and the impedance of 
the load the amplifier 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 
amplifier, you will unbalance the 
XLR input on the Juice amplifier. 
This negates the benefits 
associated with balanced lines 
and inputs.
