DPM AO-1
2ch analog audio output module
- 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
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.
