32 Input + 8 Output Modular Rack

This unit has 32 inputs + 8 outputs and is typically installed at stage side. The AD/DA conversion is 24bit/96kHz. High quality XR-1 pre-amps are provided for each input channel, which can accept both mic and line level inputs, eliminating the need for direct boxes. Phantom power and an input PAD is available for each channel.

  • - Modular “stage unit” with 32 inputs and 8 outputs on XLR connectors
  • - High Quality Pre-amps on each input channel. All new, precision-designed XR-1 preamps with massive headroom and clean, warm sound (gain range from -65 to +10 dBu typical, +28 dBu maximum input level)
  • - Audio signal and system status indicators
  • - Two REAC ports (one primary, one redundant)
  • - RS-232C interface for S-4000R Remote Controller or computer control
  • - MUTE ALL OUTPUTS button for noise-free connection of audio sources
  • - Connection port for optional redundant power supply

High Quality Pre-amps on each input channel

In an analog system, low-level microphone signals are boosted using a mic preamp only after the long, arduous journey down the analog snake. For this reason it’s difficult to avoid degradation and cross talk. The S-4000S-3208 is equipped with high quality and remote controllable XR-1 pre-amps that boost the input gain right at the microphone, where the highest quality signal is found. This ensures that your audio will sound its best. And of course once the signal is in digital form, it is immune to analog cabling losses. The XR-1 pre-amp has been specially designed for live audio applications and is made of high quality components carefully selected by Roland’s engineers.
