Connect the supplied power cable to this socket.
(3) Speakers Outputs (Amp 1 and Amp 2)
The Speaker Outputs are available as Neutrik Speakon® connectors and
standard
¼”
Jack connectors.
The minimum load that either of the amplifiers inside the GigRac 1000st
should be presented with is 4 ohms. this means that a single 4 or 8
ohm speaker can be connected to each amplifier outputs as shown in
Fig 1. Alternatively, two 8 ohm speakers can be connected in parallel to
each amplifier output, as shown in Fig 2. Two speakers connected like
this gives a combined load of 4 ohms.
Use the appropriate connector type to match the input connectors on
your loudspeakers. The GigRac 1000st is designed to work with
loudspeakers rated at either 8 ohms or 4 ohms.
Connect your loudspeakers to these outputs. The signal sent to the
Speakon® connectors and the Jack sockets is exactly the same.
