Selecting Output Wire and Connectors
It is recommended you use high quality 16 AWG, 2 or 4 conductor, heavy gauge, CL2 or
CL3 rated, 100% Oxygen-Free Copper (OFC) speaker wire. CL2 and CL3 ratings refer to
the cable jacket’s fire resistance and the voltage capacity of the wire. While both cables
have the same flame resistance capability, the CL2 cable can handle voltage spikes of up
to 150 volts while the CL3 can handle up to 300 volts. When using the 70V/100V speaker
zone output screw connectors, use terminal forks up to 10 AWG (recommended) or bare
wire. Below is a chart to help you select the appropriate size wire based on the amp to
speaker distance.
The RCS350-6 features one RCA line output. We recommend you use high quality RCA
cables such as Rockville’s RNRTR, RNRMR, or RCDR series.
Selecting Input cables
There are three ¼˝ balanced TRS mic inputs and two RCA inputs on the RCS350-6. We
recommend you use high quality Rockville cables like the RCXMB, RCXFB, or RCTR series
¼˝ TRS cables and the RNRTR, RNRMR, or RCDR series RCA cbales.
Rack Mounting
This unit should be on the bottom of the rack or above any equipment that does not
produce heat. Be sure to provide at least 1 RU (Rack Unit, 1.75˝) of space above and below.
Preferably, the side wall should be at least 2˝ from the sides of the amplifier and the back
of the rack should be open. This will ensure a source of cool air to all sides of the amplifier.
Setup
The RCS350-6’s 70V and 100V connections can be set up in a variety of ways. Please note
that utilizing direct speaker connections and speaker zone connections simultaneously is
not recommended and will cause damage to the amplifier and the speakers.
Connections
Multi-Zone 70V Speaker Output (Screw Connectors)
You may connect any number of 70-volt speakers to each zone as long as the total output
for any one zone does not exceed 100 watts and the overall total output of the zones does
not exceed 350 watts. As with the direct outputs, best practice is to allow for about 10 –
20% “head room” or extra power. So, the total output power of the speakers connected to
any one zone should not exceed 80 – 90 watts, and the total power output of all the zones
combined should not exceed 270 – 280 watts.

ATTENTION:
Check local code requirements

CAUTION: Never use shielded cable for output wiring.
WARNING: For low impedance loads only.
