NAD CI8-150 V2 DSP 8-Channel Power Amplifier

The NAD CI 8-150 V2 DSP is the powerful flagship of the NAD Custom Install series – designed for the highest demands in multi-room, commercial, and home theater installations. This 8-channel power amplifier combines tremendous power, precise digital control, and outstanding reliability in a rack-mountable chassis just two units (2U). With 8 x 150 watts of continuous power or 4 x 300 watts bridged (at 8 ohms), the CI 8-150 V2 DSP delivers impressive power reserves – while remaining stable, efficient, and perfectly controllable.

Maximum flexibility and control

The CI 8-150 V2 DSP was specifically developed for professional integrators who value network-based control and precise calibration. A modern, web-based user interface (WEB GUI) allows 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 control each channel separately. Loop outputs also allow signals to be easily routed to additional amplifiers – ideal for large systems in restaurants, conference rooms, or multi-room systems.

HybridDigital™ Core – Efficiency meets performance

At the heart of the CI 8-150 V2 DSP are eight HybridDigital™ Core amplifiers based on proven Class D technology. NAD consistently utilizes modern switching power supplies and highly efficient amplifier stages that, unlike conventional Class AB designs, dissipate virtually no energy into heat.

The result:

• 8 × 150 watts continuous power (8 ohms)
• 8 × 180 watts continuous power / 8 × 280 watts pulse power (4 ohms)
• 4 × 300 watts bridge power (8 ohms)
• Up to 800 watts of pulse 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 professional continuous operation

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

With automatic power-on (signal sensing), low power consumption (0.5 W in standby), and a network standby function, the amplifier is not only powerful but also energy-efficient. Thus, it meets the requirements of modern installations that demand both performance and sustainability.

Professional connection variety

The CI 8-150 V2 DSP offers a wide range 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 additional power amplifiers)

Control & Connectivity:

• WEB GUI for DSP configuration, status monitoring and updates
• 12 V 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 (2 U, mounting kit included)

Digital precision with DSP control

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

• 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 power amplifiers in the custom-install sector – whether for networked multi-room systems, commercial environments or high-end home theaters.
