The TOA D-901 is a modular digital audio mixer designed for professional sound installations requiring flexible signal processing, audio routing, and system control. Featuring integrated digital signal processing (DSP) and configurable input/output modules, the D-901 allows system designers to build audio mixing and distribution systems for commercial and institutional applications.

The D-901 supports compatible TOA plug-in modules, allowing the mixer to accommodate different microphone, line-level, and control requirements. Its modular architecture makes it suitable for conference facilities, houses of worship, educational institutions, public venues, and other installations requiring centralized audio management.

For applications requiring physical remote level adjustment, the D-901 can be used with the TOA D-911 Remote VCA Fader Controller and the required D-984VC VCA Control Module.

Modular Input and Output Configuration

The TOA D-901 uses a modular architecture that allows compatible input and output modules to be selected according to system requirements.

This flexibility enables installers to configure the mixer for applications involving:

• Microphone inputs

• Line-level audio sources

• Multiple audio outputs

• Audio signal routing

• External control interfaces

• Commercial sound system integration

The modular design helps accommodate different installation requirements without relying on a single fixed input/output configuration.

Integrated Digital Signal Processing

The D-901 provides onboard DSP capabilities for managing audio signals within an installed sound system.

Its digital processing and routing capabilities allow installers to configure audio paths and level relationships for the application.

These capabilities are useful for systems involving multiple microphones, background music sources, paging, and distributed audio outputs.

Remote Volume Control with TOA D-911

The D-901 supports external level control through compatible TOA control components.

When equipped with the TOA D-984VC VCA Control Module, the system can be used with the TOA D-911 Remote VCA Fader Controller.

This allows operators to make audio level adjustments using physical faders without accessing the D-901 directly.

Remote control is particularly useful when the mixer is installed in an equipment rack or equipment room while day-to-day operation takes place elsewhere.

Designed for Commercial Audio Installations

The TOA D-901 is designed for permanent audio systems where signal routing, processing, and control need to be managed from a centralized mixer.

Its modular configuration supports applications such as:

• Conference room audio

• Houses of worship

• Educational facilities

• Commercial paging

• Background music systems

• Corporate AV installations

• Public venues

• Multi-room audio distribution
