There are four three-pin Euro-style connectors labeled 1 through 4 providing the audio
inputs on the DPA Amplifiers. A single input can be mixed to one or a combination of
outputs. You can use from one to four of the inputs. The inputs are 10 kΩ balanced or
EN
unbalanced, with a sensitivity of either +4 or +14 dBu.
1.
Make sure your audio source devices are powered off.
2.
Wire the audio line-level source to up to four Euro-style connectors (supplied). You
may use either balanced inputs
NOTE!: The DPA Series has the capability of routing the inputs to different
outputs. Be sure that the connections you make here match the configuration
of the amplifier.
3.
Plug the connectors into the appropriate receptacles (ROUTABLE INPUTS 1, 2, 3, 4)

USB (Optional)
The USB cable (supplied) connects to a Mac or PC for use with the Amplifier Navigator software. You can update the amplifier firmware, save and
deploy configuration files, and more. Refer to the Amplifier Navigator online help for details.
NPIO/Heartbeat
There are two 3.5 mm Euro-style connectors on the rear of the amplifier.
• Heartbeat The heartbeat output supplies a square wave signal of 1 Hz @ 3.3 V. This signal can connect to a life-safety system to monitor the go/
no-go condition of the amplifier. The amplifier must be completely incapable of producing output for the heartbeat signal to stop. A missing
heartbeat alerts the life-safety system of the disabled condition. A user-initiated condition such as muting the outputs, placing the amplifier in
Standby mode, or placing the amplifier in Mute All mode, does not stop the heartbeat.
• GPO The GPO can be triggered (High or Low flag) by one of the following faults:
◦ All Faults
◦ Thermal Limiting
◦ Impedance (selectable impedance boundaries)
• GPI The GPI Input allows you to do one of the following from a remote location:
◦ Put the amplifier into Standby or Run mode,
◦ Mute or unmute all outputs, or
◦ Recall one of two Presets
