StudioMaster AC36II 3-In / 6-Out Digital Audio Signal Processor

KEY FEATURES OF THE STUDIOMASTER AC36Ⅱ 3-IN / 6-OUT DIGITAL AUDIO PROCESSOR

1. Introduction to the StudioMaster AC36Ⅱ Digital Audio Processor

The StudioMaster AC36Ⅱ is a professional digital audio processor featuring 3 inputs and 6 outputs. It is designed to manage, distribute and optimize audio signals in professional sound systems, including live stages, auditoriums, premium karaoke venues, churches and commercial audio installations.

Equipped with a 40-bit DSP processor, 24-bit AD/DA converters and a 48kHz sampling rate, the AC36Ⅱ provides advanced signal-processing tools that allow sound engineers to control individual signal paths and fine-tune loudspeaker systems.

2. Flexible 3-Input / 6-Output Configuration

The StudioMaster AC36Ⅱ features 3 balanced XLR inputs and 6 balanced XLR outputs, allowing it to receive signals from multiple sources and distribute them to separate loudspeaker groups.

This configuration is suitable for multi-way sound systems, including subwoofers, full-range speakers and stage monitors. Users can customize signal distribution to match the size and layout of their audio systems.

3. 40-Bit DSP and 24-Bit AD/DA Conversion

The processor combines a 40-bit DSP engine with 24-bit AD/DA converters and a 48kHz sampling rate.

This digital processing architecture supports detailed equalization, crossover configuration and signal control. Engineers can fine-tune audio characteristics according to the venue, loudspeaker configuration and intended application.

4. Advanced Input and Output EQ

The AC36Ⅱ provides independent equalization tools for its input and output processing stages. Each input channel supports 5-band parametric EQ, while each output channel features 6-band parametric EQ.

These parametric equalizers allow users to adjust individual frequency ranges, address tonal imbalances and optimize the overall frequency response of the sound system.

5. Professional Crossover Processing

The StudioMaster AC36Ⅱ supports Butterworth, Linkwitz-Riley and Bessel crossover filter types, with filter slopes ranging from -6dB/oct to -48dB/oct according to the product information.

Crossover processing divides the audio signal into frequency bands suited to different loudspeaker groups. Users can configure dedicated signal paths for subwoofers, full-range speakers and other loudspeaker components.

6. Compressor and Limiter for Output Control

The output processing section includes Compressor/Limiter functions to control signal levels and help prevent signals from exceeding configured thresholds.

These tools allow engineers to manage output levels on individual channels, helping maintain stable operation and reducing the risk of excessive signal levels affecting connected equipment.

7. Noise Gate and Input Processing Tools

The AC36Ⅱ input section supports Gain, Mute, Link, High-cut, Low-cut, Noise Gate, 5-band PEQ, Phase and Delay.

These tools help adjust input levels, manage background noise, filter unwanted frequency ranges and control phase relationships between signal paths. They provide flexible adjustment options for different installation environments.

8. Delay for Loudspeaker Time Alignment

The StudioMaster AC36Ⅱ supports a delay function with a specified maximum time of over 680ms and an adjustment step of 0.021ms.

This function helps align sound arrival times between loudspeaker clusters installed at different distances. It is particularly useful in stages, auditoriums and line array systems where timing alignment contributes to consistent sound coverage.

9. Flexible Matrix Routing

Matrix routing allows users to assign input signals to selected output channels.

With its 3-input / 6-output configuration, the AC36Ⅱ can accommodate different loudspeaker system layouts. Engineers can route signals separately to subwoofers, main speakers, auxiliary loudspeakers or stage monitors as required.

10. Storage for 30 User Presets

The AC36Ⅱ supports 30 user presets and 1 factory preset, according to the product information.

Preset storage allows users to save customized processing configurations and recall suitable settings when changing operating requirements or restoring a previously configured system.

11. Clear LCD Display

The processor features a 20 × 2-character LCD display for configuration information and direct adjustment.

The display helps users monitor processing parameters and makes system setup, inspection and operation more convenient.

12. USB, RS232 and RS485 Control Connectivity

According to the detailed product description, the StudioMaster AC36Ⅱ supports USB, RS232 and RS485 control interfaces.

These connections allow the processor to be integrated into computer-based configuration workflows and compatible control systems, making it suitable for fixed installations and centralized audio management.

13. Compact 1U Rack Design

The StudioMaster AC36Ⅱ is described as a compact 1U rack processor intended for professional audio equipment installations.

Its 3-input / 6-output configuration and integrated DSP processing allow it to serve as a central unit for signal distribution, crossover management and loudspeaker adjustment. The rack design also supports neat installation alongside other professional audio equipment.

14. Applications of the StudioMaster AC36Ⅱ

With its 3-input / 6-output configuration and advanced signal-processing tools, the StudioMaster AC36Ⅱ is suitable for a variety of professional audio applications:

Professional stage and live performance sound systems.

Line array and multi-way loudspeaker systems.

Auditoriums, meeting rooms and event venues.

Commercial and premium karaoke installations.

Church and commercial sound systems.

Fixed audio installations requiring flexible signal routing and multi-zone loudspeaker management.

The StudioMaster AC36Ⅱ is a practical DSP solution for systems requiring a 3-input / 6-output processor with EQ, crossover, compressor/limiter, noise gate, delay and matrix routing capabilities.
