Brax DSP – Output Analog ESS

Brax DSP – Output Analog ESS – high-end stereo analog output module

This is the top analog output option for the modular BRAX DSP: a stereo output module for the CORE Model, made in Germany and factory-installed as part of the initial configuration. It is compatible only with the BRAX DSP CORE Model.

Conversion is handled by ESS Technology’s ES9039Q2M, a 32-bit two-channel D/A converter with HyperStream IV Dual DAC technology and the SABRE HiFi architecture, credited with wide dynamic range and very low distortion. The analog stage uses a TI/BurrBrown OPA1612 op-amp with SoundPlus technology, and a dual-supply layout gives each stereo channel its own power supply.

Key Features

• ESS ES9039Q2M D/A converter: 32-bit, 2-channel, with HyperStream IV Dual DAC technology and SABRE HiFi architecture.
• TI/BurrBrown OPA1612: Op-amp with SoundPlus technology in the analog signal path.
• Dual-supply design: Separate power supply for each stereo channel.
• Seven FIR output filters: Software-configurable digital FIR filters with different characteristics.
• Switchable output voltage: 2, 4 or 8 V RMS.
• 192 kHz operation: Frequency response 10 Hz – 80 kHz.
• Excellent measured values: SNR 130 dB (A-weighted), THD+N -116 dB (0.00015 %), IMD -106 dB (0.0005 %).
• High channel separation: Crosstalk below -110 dB at 1 kHz.
• Measurements in software: Measured values are displayed in the DSP PC-Tool (from V5.05).

Inputs & Outputs

• 1 × stereo analog RCA output pair, output voltage 2 / 4 / 8 V RMS adjustable.

DSP & Sound Tuning

• Seven selectable digital FIR output filters, configured in software.
• Display of measured values requires DSP PC-Tool V5.05 or later.

Installation & Connectivity Notes

• Compatible only with the BRAX DSP CORE Model.
