To terminate an ISMT speaker to Amplifier Chassis 1, Amplifier 2:
• On the target amplified audio distribution card, ter/- speaker wires to primary
Amp B f (F+) and forward – (F-) spring terminal block (ensure wires are
terminated correctly, as an ISMT speaker will not communicate when wires are
crossed)
• If a speaker loop is needed, connect return speaker wire to r (R+) and reverse
– (R-) spring terminal block
• This version of the amplifier audio distribution card (P-AADC2-G) allows the
amplifier to be connected to up to two speaker runs. If a second speaker run is needed,
wire the second speaker wire set to the secondary set of terminal blocks
