so you will probably not need an additional amplifier.
Each leg of the output is protected with a 1 A slow-
blow fuse (20-mm European type). Although a three-
pin screw-terminal plug connector is provided, only
the outer two pins are used (see Figure 4.14).
The channel to monitor can only be selected with IQ
software while the unit is connected to an
IQ System.
When a selection is made, the IQ software will first turn

The IQ components in each Crown Bus loop are wired
sequentially. The loop begins and ends with the IQ
interface. The output of one IQ component “loops” to
the input of the next and so on as shown in Figure 4.13.
4.7 Using an Audio Monitor
If desired, you can audibly monitor the audio signal of
any channel with the Loudspeaker Monitor Output
shown in Figure 4.14:
Each of the SLM-8’s audio input channels connects to
a relay. The output of each relay is connected to the
fused Loudspeaker Monitor Output “bus.” Break-be-
fore-make relays are used to prevent two input chan-
nels from being shorted together.
Any of the eight channels can be connected to the
monitor output but they can only be connected one at
a time. The selection is made with IQ software. Up to
10 watts of power is available at the output connector,
