## Product description

SMART-PA8160 is an 8-channel class D power amplifier of Ambient System’s smartVES system for 100 V and 50 V loudspeaker systems. The outputs are transformer-isolated. The rated power per channel is 160 W. The channels can be bridged, giving outputs of 1 × 320 W + 6 × 160 W, 2 × 320 W + 4 × 160 W, 3 × 320 W + 2 × 160 W or 4 × 320 W.

The amplifier operates on 48 V DC, so it can be connected to a battery-backed supply. Power comes from SMART-PS48800 power supply units via the SMART-PSM48 power management unit. The power management unit includes a battery charger and meets the requirements of EN 54-4.

The rear panel has level controls for each channel, a volt-free general fault contact and the connectors. The enclosure is 2U high and is mounted in a 19-inch rack. This model has no background music (BGM) inputs. The model with background music inputs is SMART-PA8160E.
