NAD CI8-150 V2 DSP 8-Channel Power Amplifier

The NAD CI 8-150 V2 DSP is the high-performance flagship of the NAD Custom Install series – designed for the most demanding applications in multiroom, commercial, and home theater installations. This 8-channel power amplifier combines enormous power, precise digital control, and outstanding reliability in a rack-mountable chassis that is only two rack units (2U) high. With 8 x 150 watts of continuous power or 4 x 300 watts in bridged mode (into 8 ohms), the CI 8-150 V2 DSP delivers impressive power reserves while remaining consistently stable, efficient, and perfectly controllable.

Maximum flexibility and control

The CI 8-150 V2 DSP was specifically designed for professional integrators who value network-based control and precise calibration. A modern, web-based user interface (Web GUI) allows for convenient configuration and monitoring of the amplifier – directly from the browser, without the need for additional software.

The intuitive interface provides access to:

• Digital signal processing (DSP) with individual channel control
• Real-time temperature and power status
• System diagnostics and remote maintenance (power on/off, firmware update, factory reset)

Furthermore, installers can use the global inputs to supply all eight channels with the same signal simultaneously, or optionally control each channel separately. Loop outputs also allow signals to be easily passed on to additional amplifiers – ideal for large systems in restaurants, conference rooms, or multi-room setups.

HybridDigital™ Core – Efficiency meets performance

At the heart of the CI 8-150 V2 DSP are eight HybridDigital™ Core power amplifiers based on proven Class-D technology. NAD consistently relies on modern switching power supplies and highly efficient amplifier stages, which, unlike conventional Class-AB designs, convert very little energy into heat.

The result:

• 8 × 150 watts continuous power (8 ohms)
• 8 × 180 watts continuous power / 8 × 280 watts peak power (4 ohms)
• 4 × 300 watts bridged power (8 ohms)
• Up to 800 watts of peak power (2 channels active)

This amplifier architecture delivers exceptionally linear and stable performance across all loads – even with long cable runs or complex speaker impedances. Even in large, networked systems, the sound remains precise, low-noise, and dynamic.

Reliability for continuous professional operation

The CI 8-150 V2 DSP was designed for long-term stability and continuous rack use. Its robust steel chassis provides effective heat dissipation, while integrated signal and temperature monitoring ensures safe operation at all times.

With an automatic switch-on function (signal sensing), low power consumption (0.5 W in standby) and a network standby function, the amplifier meets the requirements of modern installations.

Professional connectivity options

The CI 8-150 V2 DSP offers a wide selection of inputs, outputs and control options, ensuring maximum flexibility in any installation environment:

Audio inputs:

• 2 × coaxial digital inputs
• 2 × optical digital inputs
• 4 × analog stereo high-level inputs (RCA)
• 2 × analog global stereo inputs and outputs (signal loop-through to further power amplifiers)

Control & Connectivity:

• WEB GUI for DSP configuration, status monitoring and updates
• 12V trigger input for external control
• IR input/output for integration into smart control systems
• Phoenix speaker terminals for secure, tool-free connection
• 19-inch rack preparation (2U, mounting kit included)

Digital precision with DSP control

The integrated DSP engine allows precise control over every audio signal. It enables:

• Fine-tuning of the frequency response per channel
• Gain adjustment and equalizer settings
• Zone optimization for individual room acoustics

These features make the CI 8-150 V2 DSP one of the most flexible and powerful amplifiers in the custom-install sector – whether for networked multiroom systems, commercial environments or high-end home cinemas.
