IV. Trigger In
This input (Fig. 8) is designed for a mono 3.5mm plug to accept a trigger voltage coming in from an external source.
Any voltage ranging from 3-30 volts, AC or DC, will cause the amplifier to turn on when the Power switch is in the Trigger mode.

V. Unit On
This output (Fig. 9) provides a constant 12 volts DC when the amplifier is powered on. This is useful for powering on external equipment with the
D460.

VI. Speaker Impedance
This switch (Fig. 10) allows for the adjusting of the impedance of the amplifier. By default the amplifier will be set at 8 ohms. This is fine if you are
powering a pair of 8 ohm speakers, or a single stereo speaker rated at 8 ohms. In installations where 2 pairs of 8 ohm speakers will be used, or a
pair of 4 ohm speakers are being utilized, the impedance of the amplifier should be set to 4 ohms.
