Chevin A2000 - Input Signal Connections; Output Connections and Speakon Wiring

All inputs on the amplifier are electronically balanced and can accept signals from balanced and
unbalanced sources.
■ A750 / A1000 / A1500 / A2000 / A2500 / A3000 / A5000 / A6000 / Q900 amplifiers have male
and female XLR connectors on the input of each channel. These connectors are wired in parallel.
■ Q6 amplifiers have one female XLR connector on the input of each channel.
Nota Bene:
● The amplifiers are not mixing amplifiers - do not directly connect any channel to more than one
signal source.
● Maintain the same phase polarity on all equipment in the signal chain.
PIN 1 GROUND, connects directly to chassis
PIN 2 HOT (+)
PIN 3 COLD ( - )
■ Fit XLR connectors at both ends of the cable.
■ PIN 1 connects via the cable braid (screen). Always connect the screen at both ends of the
cable.
■ PINS 2 & 3 connect via the two signal wires of the cable.
■ At the source end of the cable, the cable screen and cold (-) signal wire connect to the chassis
of the source equipment via the sleeve of the jack plug / phono connector or PIN 1 of the
XLR-type plug.
■ The signal carrying conductor, which connects to PIN 2 of the XLR plug at the amplifier end,
connects to the hot output terminal of the source equipment via the tip of the jack plug, the pin
of the phono connector or whichever XLR PIN carries the signal.
Connection is made to the amplifier’s load via Neutrik Speakon sockets. As with input connectors,
maintain phase polarity throughout the system.
■ A750 / A1000 / A1500 / A2000 / A3000 / Q900: 2 parallel-connected Speakon sockets per
channel, wired as follows:
1+ = HOT 2+ = NO CONNECTION
1 - = COLD 2 - = GROUND
■ A2500 / A5000 / A6000: 2 parallel connected Speakon sockets per channel, wired as follows:
1+ = HOT 2+ = NO CONNECTION
1 - = COLD (NOT GROUND) 2 - = COLD (NOT GROUND)
● The A2500 / A5000 / A6000 outputs are permanently connected in bridge mode.
Both hot and cold outputs carry high level signal. Further bridging is impossible.
● Do not connect any part of the A2500 /A5000/ A6000 outputs to ground.
● Take care when using loudspeaker controllers or processors.
