NAD CI16-60

The NAD CI16-60 DSP is a 2U rack-mount multiroom integration amplifier, designed to power up to 8 stereo zones via its 16 channels. It uses digital amplification and features built-in digital signal processing (DSP) for audio optimization. Each channel delivers up to 60 watts at 8 ohms with all channels active simultaneously. Channel pairs can be bridged to provide up to 140 watts, allowing the amplifier to be tailored to different installation needs.

Mechanical Design Engineered for Professional Integration

The CI16-60 features a standard 19-inch rack chassis with a height of 2U (100 mm), weighing 10.3 kg and measuring 483 x 100 x 435 mm. This remarkable compactness for a 16-channel amplifier demonstrates the highly optimized internal architecture. The brushed aluminum front panel, a hallmark of NAD’s minimalist design, incorporates discreet status LEDs for quick visual diagnostics of operating status.

The rear panel layout reveals meticulous organization of connections. The 16 pairs of stereo RCA inputs are logically arranged, each with a “loop through” output for daisy-chaining to other amplifiers. The screw-type Phoenix terminals accept cables up to 10 AWG, a rare capacity in this category of integration amplifiers, reflecting the attention to professional installations. The generous spacing between connectors greatly facilitates wiring, even in the densest configurations.

A particularly ingenious aspect is the cooling system. Thermostatic fans draw cool air in from the front and expel it out the back, eliminating the need for ventilation gaps between stacked rack units. This front-to-back airflow optimizes rack space—a significant advantage in installations where every rack unit counts. The fans only activate based on internal temperature, ensuring quiet operation during moderate volume use.

HybridDigital Technology with Hypex UcD Modules at the Heart of Performance

The CI16-60 relies on a customized version of Hypex UcD (Universal class D) amplification modules, a technology that has revolutionized high-fidelity digital amplification. These modules, initially developed by Bruno Putzeys at Philips before being perfected at Hypex, represent the culmination of decades of research in digital amplification.

The UcD topology stands out for its self-oscillating loop architecture controlled by phase shift, with feedback taken directly from the speaker output. This approach ensures a perfectly flat frequency response regardless of load impedance, near-constant distortion behavior across the entire audio band, and extremely low radiated and conducted electromagnetic emissions. The damping factor of 110 at 1 kHz into 8 ohms ensures precise speaker control, which is especially critical in installations with long cable runs.

The amplifier maintains its exceptional performance even under the most demanding conditions. With a THD of just 0.05% from 20 Hz to 3 kHz and 0.2% from 3 kHz to 20 kHz at 1 to 50 watts, the CI16-60 preserves signal purity even at high volumes. The signal-to-noise ratio of 80 dB ensures remarkable background silence, essential for critical listening zones. The ability to deliver a peak current of 15 amps for 1 millisecond at 1 ohm demonstrates substantial dynamic reserves, allowing faithful reproduction of the most demanding musical transients.

Full Disclosure Power Approach: Transparency According to NAD

In 2002, NAD developed its own power measurement standard, Full Disclosure Power (FDP), in response to the often misleading specifications in the industry. Unlike FTC standards, which allow measurements under simplified conditions (8 ohms, 1 kHz, one channel only), NAD measures its amplifiers under the most severe conditions: 4-ohm load, all channels active simultaneously, across the full 20 Hz to 20 kHz bandwidth, and at the specified nominal distortion.

For the CI16-60, this means the stated 60 watts per channel are truly available on all 16 channels simultaneously, even under difficult loads. This conservative approach explains why NAD amplifiers often seem less powerful on paper than their competitors, while in reality delivering more usable power under real-world conditions. The IHF dynamic power reaches 65 watts at 8 ohms and 125 watts at 4 ohms with all channels active, illustrating the reserves available for musical peaks.

Bridge mode allows the amplifier to be reconfigured as 8 channels of 140 watts at 8 ohms, with peaks up to 270 watts in dynamic power. This flexibility allows power distribution to be tailored to the specific needs of each installation, whether powering low-sensitivity in-wall speakers or outdoor systems requiring more power.

WebUI 2025 Interface: Total Control at Your Fingertips

The CI16-60’s web interface, updated in 2025, represents a major advancement in multiroom amplifier management. Accessible via any browser on PC, Mac, smartphone, or tablet, it offers comprehensive control without the need for proprietary apps.

The real-time dashboard displays the status of each channel, including signal levels, temperature, and any error conditions. The virtual routing matrix allows any input to be assigned to any output without physically manipulating cables, offering total flexibility in zone configuration. Each channel features individual gain controls, enabling precise level balancing between different zones or speaker types.

The built-in DSP processor offers a 5-band parametric equalizer per channel, with full control over center frequency, Q factor, and gain for each band. Configurable high-pass and low-pass filters allow optimization for different speaker types or integration of subwoofers. New features include a configurable limiter to protect speakers, phase control to correct timing alignment issues, and an adjustable delay up to 100 ms to synchronize distant zones.

DSP profile creation allows different configurations to be saved for various uses—critical listening, background music, voice announcements—and to switch between them instantly. Password protection secures access to critical settings while allowing end users to access basic functions.

System Integration and Home Automation Compatibility

The CI16-60 integrates seamlessly into professional home automation ecosystems thanks to drivers available for major platforms: Crestron, Control4, Elan, RTI, and URC. The RS-232 port offers bidirectional serial control for installations requiring deep integration with third-party systems.

The 12V trigger input accepts a voltage range of 3 to 30V DC, ensuring compatibility with virtually all trigger systems. IR in/out ports allow integration into existing infrared control chains, while automatic audio signal detection (threshold at 3 mV) can trigger automatic power-on of specific zones.

Eco mode reduces standby consumption to 0.5 watts, with network standby maintained at 3 watts, allowing wake-up via IP. Multiple power-on options—trigger, audio detection, IP control, scheduled programming—offer maximum flexibility to suit usage habits.

BluOS Ecosystem and Synergy with NAD Products

The CI16-60 integrates perfectly into the NAD/Bluesound ecosystem to create complete multiroom solutions. Pairing with the CI 580 V2, a 4-zone BluOS rack streamer, transforms the setup into a high-resolution audio distribution system capable of streaming services, local libraries, and traditional sources to 8 independent zones.

The Bluesound NODE, a more affordable alternative, can be assigned to specific zones to add targeted streaming capabilities. The BluOS platform, developed by Lenbrook, natively supports a multitude of services including Spotify Connect, Tidal Connect, Qobuz, Amazon Music HD, and full MQA decoding. Integration with Roon Ready and Apple AirPlay 2 further expands source possibilities.

Perfect synchronization between BluOS zones enables simultaneous playback in multiple rooms with no audible delay, creating a coherent sound environment throughout the home. Zone groups can be created and modified dynamically via the BluOS app, offering total flexibility in managing listening spaces.
