Introducing Studiomaster AC 36-II Audio Processing

Studiomaster AC 36-II is a high-end digital audio processor with 3 inputs and 6 outputs, providing flexible and precise control for professional stage, hall, and karaoke sound systems.

This product features a 40-bit DSP processor, 48kHz sampling rate, and 24-bit AD/DA conversion, allowing for high-quality, frequency-accurate audio processing.

Technical parameters of the product to consider:

• Device Type – Digital Audio Processor (DSP): This is a specialized device for processing digital audio signals, allowing deep intervention in frequency bands, phase, delay, EQ... to optimize output sound quality. DSP is the brain of professional sound systems - from high-end karaoke, performance stages to large halls.
• Number of channels – 3 Input / 6 Output: The 3-input and 6-output configuration meets complex signal processing and zoning needs. Each input can be distributed to multiple outputs with a free matrix assignment structure, suitable for multi-speaker systems (sub, full, monitor...).
• Sampling rate – 48kHz: The 48kHz sampling rate is the professional standard, enough to reproduce clear, smooth sound, suitable for both music and speech.
• Signal Processor – 40-bit DSP: The 40-bit DSP chip allows for much more precise processing than conventional 24-bit, with greater dynamics and more detailed sound range.
• AD/DA converter – 24-bit: Analog to Digital / Digital to Analog Converter 24-bit converts signals between analog and digital with high fidelity, preserving original details.
• Input EQ – 5-band PEQ: 5-band EQ input allows fine-tuning of each source such as microphone, karaoke player or mixer. Filter types can be selected: Peak, H-Shelf, L-Shelf, LP/HP, very diverse.
• Output EQ – 6-band PEQ: Allows detailed adjustment of each individual speaker according to its characteristics and installation location. Easily increase bass, cut treble, or soften mid-range depending on the space.
• Crossover – Butterworth / Linkwitz-Riley / Bessel: Supports the most popular and accurate crossover algorithms in the audio industry. Each algorithm has its own slope and sound characteristics to suit each type of speaker.
• Slope filter – -6dB/oct to -48dB/oct: The larger the filter slope, the more severe the cut-off outside the frequency range. Allows tight control of the crossover area, avoiding overlapping frequency ranges between speakers.
• Matrix Assign – Free: Allows the user to freely assign each input to any output, according to a custom matrix.
• Dimensions – 4.4 x 20.5 x 8.2 cm, Weight – 2.8kg: Compact design, easy to install in standard rack cabinets, suitable for both fixed and mobile systems.

Detailed review of Studiomaster AC 36-II

Perfect design and quality

Studiomaster AC 36-II has a compact, sturdy design with dimensions of only 4.4 x 20.5 x 8.2 cm and a weight of 2.8 kg. The entire case is made of high-quality metal to increase heat dissipation and prevent signal interference. The minimalist front interface clearly displays parameters, making it convenient to monitor operating status.

This device is designed with 1U rackmount standard, suitable for installation in cabinets or for carrying to performances, installing mobile systems. From appearance to connection port layout, everything shows professionalism and is suitable for sound systems with high durability requirements.

Digital signal processing (DSP) performance

With a 40-bit DSP processor and a 48kHz sampling rate, the Studiomaster AC 36-II delivers superior audio processing performance. The integrated 24-bit A/D and D/A signal conversion ensures high-fidelity sound without distortion or loss of detail.

When compared to popular digital reverb models, the sound quality from AC 36-II clearly shows the difference in sound clarity, dynamics and stability even when operating for a long time. This is the ideal device for high-end karaoke rooms, performance stages or professional hall sound systems.

Input processing capabilities

In terms of input, AC 36-II supports 3 input ports with full functions such as Gain, Mute, High-cut / Low-cut, Noise gate, Phase, Delay and 5-band PEQ. The strength lies in the ability to adjust each parameter in great detail: users can set each frequency, gain and bandwidth for each EQ band with an adjustment step of only 0.1dB.

The frequency cut-off filters effectively reduce feedback, especially when used with wireless microphones or environments with strong reflections. In addition, the Channel Link feature helps synchronize settings between inputs when using left and right microphones in parallel.

Output processing capability

The Studiomaster AC 36-II offers six discrete outputs, supporting extremely flexible matrix assignment. Each output channel features a full 6-band PEQ, Crossover, Compressor/Limiter, Phase, Delay and Gain/Mute.

This allows users to configure complex sound systems such as: 2 full speakers + 1 sub, 2 front + rear speaker zones, or a zoned sound system in the hall. The compressor and limiter operate stably, helping to protect the speakers from clipping when the volume increases suddenly. The delay capability for each output channel supports time alignment between speakers, ensuring that the sound reaching the listener's ears is in phase and clear.

Filters and crossovers

One of the notable technical strengths is the AC 36-II's in-depth crossover system. The device supports Butterworth, Linkwitz-Riley, Bessel filters with adjustable slopes from -6dB/oct to -48dB/oct.

These filters are essential when setting up a crossover between a subwoofer and a full-range speaker, ensuring that there is no overlap in frequency bands that can cause hum or loss of bass. Full support for filter types makes it easy for technicians to optimize the system for each specific room space, from karaoke rooms to outdoor stages.

Applications of Studiomaster AC 36-II

The Studiomaster AC 36-II is an extremely versatile digital signal processor, widely used in professional audio models thanks to its flexible processing, detailed adjustment and high stability. Here are some typical practical applications of this device:

• Application in professional karaoke system.
• Application in stage system - hall - live performance.
• Applications in church, school, conference center sound.
• Applications in mini studios or high quality personal audio.

Frequently Asked Questions about Studiomaster AC 36-II Digital Signal Processor

Is the Studiomaster AC 36-II a mixer?

The Studiomaster AC 36-II is not a mixer in the traditional sense. It is a digital audio processor, which does not have the function of mixing signals from multiple input sources like a mixer, but its main task is to deeply process pre-mixed audio signals - such as adjusting EQ, frequency division, delay, phase and volume limit. In professional audio systems, this device is often used after the mixer, playing the role of managing the quality of the signal output to the speakers.

Can Studiomaster AC 36-II be used standalone without a mixer?

In theory, it is possible to connect an audio source directly to the AC 36-II, but in practice it is not recommended. Because this device does not have as many input ports as a dedicated mixer, does not support phantom power for condenser microphones, and does not have a quick volume knob. Using it alone will limit its functions and make it difficult to operate. Therefore, it is recommended to use the AC 36-II in combination with an analog or digital mixer to maximize the signal processing efficiency.

Does the Studiomaster AC 36-II have control software? Is it easy to use?

Yes. The device comes with control software installed on the computer, connected via USB port or LAN. The software interface is quite intuitive, allowing users to configure EQ for each frequency band, adjust delay and phase to the mm, and perform matrix routing quickly. However, to fully exploit the DSP feature, users should have basic knowledge of acoustics, frequency and signal processing. For beginners, initial guidance from a technician is required.

Can one signal source be split to multiple speakers using AC 1-II?

Absolutely. This is one of the most powerful features of Studiomaster AC 36-II. With 3 input – 6 output configuration and free Matrix Assign function, users can route any signal to any output. For example, you can send a signal from a microphone to a full-range speaker, monitor speaker and subwoofer independently, each output can have its own EQ, delay, crossover. This is extremely ideal for multi-speaker systems such as stage, multi-room karaoke, or church sound.
