Quick guide from the manual
The Biamp Voltera D 1200.2M is a 4-channel power amplifier with integrated high-performance DSP, designed for complex audio processing and distribution. This document provides technical specifications and interface details for professional installation and system integration.
Device Overview
The amplifier features a total output of 1200W and includes advanced DSP capabilities comparable to the TesiraFORTE series. It supports various network media formats and provides flexible channel output configurations.
Network and Connectivity
- Ports: 2 x LAN 1000 Base-T.
- Media Formats: Dante, AES67, AVB.
- Network Modes: Converged, Split, Redundant.
- PoE+ Support: Allows the processor to continue operating during a power outage if connected to a UPS-protected PoE+ switch.
- Interfaces: Tesira and VenueTune for remote control; TTP for third-party integration.
Signal Processing and Performance
The device includes sophisticated audio processing, such as 2048-tap FIR filters, 24-band IIR filters, dynamic EQ, and temperature/peak limiters with side-chaining. It features an analog redundancy function in case of digital audio loss.
Installation and Environment
- Cooling: Variable speed fan with front-to-back airflow.
- Operating Conditions: 0-40°C, 0-95% relative humidity (non-condensing), altitude up to 2000m.
- Power: 100-240 VAC, 50/60 Hz.
- Dimensions: 44 x 444 x 430 mm.
- Weight: 7.6 kg.
Front and Rear Panel Interfaces
The front panel includes status indicators for system health, device activity, and channel-specific status (mute, signal, limit, temp). The rear panel provides GPIO pins for logic/voltage control, terminal blocks for analog inputs and speaker outputs, and a detachable IEC C14 power inlet.
Practical help
Common problems
Digital audio signal loss
The device features an automatic analog redundancy function to maintain signal flow.
Power outage during operation
If connected to a UPS-protected PoE+ switch, the processor can continue to operate via PoE+ power.
Before use
- Ensure the power source is within 100-240 VAC, 50/60 Hz.
- Verify the network environment supports Dante, AES67, or AVB.
- Check that the installation site allows for front-to-back airflow for cooling.
- Ensure speaker cables are compatible with the 2-pin terminal block (up to 8 mm² / 8.2 AWG).
Specs in practice
- Total Output
- 1200W total power when all channels are driven.
- Network Latency
- AVB: 2 ms; Dante: 1/2 ms.
- Default Gain
- 29 dB (analog input to output).
