The DPM AO-1 is 2-channel analog audio output
module for the DPM 8016 PROMATRIX CONTROLLER.
The audio signals are connected via screw-in
Euroblock connectors. The output level of both
channels can be switched internally between +6 dBu
and +18 dBu.
Linear, high-precision 24 bit converters are used for
the D/A conversion. The internal signal preparation
uses a 48-bit name length.
Other AO-1 properties:
• 109 dB dynamic range – for the best audio
performance without disruptive incidental noise
• 100 Ω symmetrical output driver – loss-free control of
multiple parallel switched output stages and long
cables
• Output relay – activation delay and rapid separation
for effective suppression of input and output noise.
Automatic control for parallel wiring in redundant
systems
• Automatic configuration – mounting changes/
deviations are detected and displayed in IRIS-Net
• Output transformer – transformers (Lundahl LL1517)
can be retrofitted as an option

Installation/configuration notes
Mounting
1. Switch off the DPM 8016 and disconnect it from the
power supply
2. Unscrew the blank panel on the back panel (2 screws
at the back)
3. Insert the DPM AO-1 module into the required slot
and fix it to the back panel with 2 screws (see the
diagram)
4. Connect the DPM 8016 to the mains and switch on
5. The DPM AO-1 module is automatically detected in
the device.
Mounting
Euroblock connecting cable – XLR
Retrofitting output transformer in output A (or
output B)
1. Remove R80 and R81 resistors (output B: R82 and
R83)
2. If necessary, unsolder the eleven soldering points for
the transformer on the circuit board
3. Bridge the two soldering points of R36 (output B:
R38) (0 W). See arrow in the diagram
4. Solder the transformer (Lundahl LL1517) at position
T1 (output B: T2)
Retrofit the output transformer
