10.5 Equalisation
For use with active equalised Bose
®
loudspeakers, please use the Panaray

System Digital Controller or the
appropriate EQ cards. The EQ cards must be EQ card series II-s. To install the cards, the amplifier must be
opened. For instructions, please refer to the EQ card manual which comes with the card.
11.Loudspeaker Output Connections
The impedance of the connected loudspeaker line could be between 2 Ohm and 16 Ohm. The minimal
connected loudspeaker impedance is 2 Ohm. In BRIDGE operation mode the minimal connected
impedance must be 4 Ohm.
11.1 Output wiring
Use heavy gauge wire for speaker connections. The greater the distance between the amplifier and the
speakers, the larger the diameter the wire should be. This will minimize power losses across the wire and
improve damping of the speaker. Wire thickness specifications (gauges) get larger as the wire gets
thinner. So a 14-gauge wire is thicker than 18-gauge wire.
11.2 Output Connectors
The Loudspeaker cables should be connected to the PHOENIX output connectors. Channel numbers and
the polarity are labeled on the connectors.
11.3 100 Volt Systems
For 100 Volt applications, the speaker output connections may be connected to a transformer package
Trapack 2 or Trapack 4. See table below.
