High-Output Monoblock Amplifier • 500W into 8 Ohms • 800W into 4 Ohms • 70V/100V Line Support • Mono-Summing RCA Input • Dual Euroblock Outputs • Selectable High-Pass Filter • Compact 1U Rack Design
The Naim CI-NAP 101 Mono Power Amplifier brings substantial Naim amplification to professionally integrated residential, commercial, marine, and architectural audio systems. Its compact 1U chassis delivers exceptional output from a single channel while supporting both conventional low-impedance loudspeakers and distributed 70V or 100V speaker systems.
Delivering 500 watts into an 8-ohm load and 800 watts into 4 ohms, the CI-NAP 101 is engineered for demanding in-wall loudspeakers, passive subwoofers, high-output cinema channels, and other applications where dynamic authority and dependable power are essential. Its ability to operate with loads as low as 2 ohms also makes it particularly well suited to advanced multi-driver loudspeaker configurations.
For distributed-audio installations, the amplifier supplies up to 150 watts through a 70V line or 240 watts through a 100V line. This flexibility allows a single model to serve applications ranging from a high-performance private theater to a multi-speaker outdoor, hospitality, retail, or whole-property audio system.
Stereo RCA inputs are summed internally to mono, simplifying connection to stereo source components and AV processors. A corresponding stereo RCA line output allows the incoming signal to be passed to another amplifier, making it easier to expand a system with additional channels or zones.
Two Euroblock speaker outputs support convenient parallel wiring, while front-accessible level adjustment and operating controls help installers configure the amplifier for the connected loudspeakers. A selectable high-pass filter is available when using high-impedance 70V or 100V systems, helping protect compatible speakers from frequencies below their intended operating range.
The Naim CI-NAP 101 Mono Power Amplifier also includes input-signal detection and automatically powers down after approximately 20 minutes without a signal. Combined with its universal 100–240V power supply, compact rack-mount form, and ultra-quiet operation, it offers the performance and installation flexibility required for sophisticated custom audio projects.
High-Output Mono Amplification — By dedicating its power supply and amplification circuitry to one channel, the CI-NAP 101 can deliver the current and control required for large in-wall speakers, passive subwoofer arrays, and high-output theater channels. A monoblock configuration also allows installers to scale the number of amplifiers precisely to the project.
Low-Impedance Power Delivery — The amplifier produces 500 watts into 8 ohms and 800 watts into 4 ohms. This increase in output into the lower load reflects the current capability needed to maintain dynamics and control when loudspeaker impedance becomes more demanding.
2-Ohm Load Capability — Support for loads as low as 2 ohms gives the amplifier additional flexibility with specialized speaker arrays and parallel driver configurations. This makes it a strong match for installations using multiple low-impedance bass drivers from one mono channel.
Dedicated 70V and 100V Operation — The CI-NAP 101 can directly power high-impedance distributed loudspeaker systems. These systems allow multiple compatible speakers to share an amplifier channel and are commonly used where long cable runs, broad coverage, or many speaker locations are required.
Selectable High-Pass Filtering — High-impedance operation provides selectable low-frequency filtering, with published line-response options beginning at either 50Hz or 120Hz. Selecting an appropriate crossover can reduce unnecessary cone movement and transformer saturation in distributed loudspeakers that are not designed to reproduce deep bass.
Wide Low-Impedance Frequency Response — In conventional low-impedance mode, the amplifier is rated from 3Hz to 70kHz. This extended bandwidth helps preserve phase integrity and transient detail throughout the audible range.
Low Distortion Architecture — Total harmonic distortion plus noise is rated below 0.008 percent. Low distortion allows musical textures, dialogue, effects, and spatial information to remain clean even when the amplifier is producing substantial output.
29dB Analog Gain — The standardized gain structure helps the amplifier integrate with AV processors, preamplifiers, matrix systems, and other custom-installation electronics.
Mono-Summing Input Stage — The stereo RCA input receives both left and right signals and combines them into mono. This is valuable when powering a subwoofer or mono zone from a stereo source because information present in either channel is retained.
47k-Ohm Input Impedance — The high input impedance presents an easy load to compatible source components, preamplifiers, processors, and distributed-audio controllers.
Loop-Through RCA Connections — Stereo analog outputs carry the incoming line-level signal onward to another amplifier. Installers can use this connection to feed multiple CI-NAP 101 amplifiers, additional zones, or complementary system channels.
Dual Euroblock Speaker Connections — Two removable Euroblock outputs provide secure, installer-friendly terminations. The pair of connectors also makes parallel loudspeaker wiring more convenient than placing multiple conductors into a single terminal.
Passive Subwoofer Capability — With up to 800 watts into 4 ohms and support for still lower impedance loads, the amplifier can provide the output needed for compatible passive in-wall or architectural subwoofer systems.
Focal 1000 Series Integration — The amplifier is particularly well suited to ambitious Focal architectural systems, including configurations that combine a 1000 IWLCR Utopia loudspeaker with compatible 1000 IWSUB Utopia bass modules.
Custom Cinema Applications — When connected to an AV processor, the CI-NAP 101 can power an individual front, center, surround, height, or subwoofer channel. Using dedicated amplification allows a theater system to be scaled according to each speaker’s output and power requirements.
Distributed Outdoor Audio — Its 70V and 100V capability makes it suitable for powering compatible outdoor loudspeakers across patios, pool areas, landscaped spaces, and large properties where conventional low-impedance wiring may be less practical.
Signal-Sensing Operation — The amplifier monitors its analog input for an audio signal. This allows it to wake when required and reduces the need for routine manual power control.
Automatic Energy Management — After approximately 20 minutes without an input signal, the amplifier automatically powers down. This reduces unnecessary energy use and heat generation in equipment racks.
Universal Mains Compatibility — A 100–240V power supply enables use across international electrical systems without requiring different amplifier models for each region.
Compact Thermal Design — The 1U chassis measures approximately 1.75 inches high while delivering unusually high power for its size. Its rack-oriented construction allows multiple amplifiers to be installed efficiently in a centralized equipment location.
Ultra-Quiet Installation Performance — Mechanical and electrical noise are carefully managed so the amplifier can operate without distracting from quiet listening environments or adding unwanted noise to sensitive audio systems.
Naim and Focal Engineering Partnership — The Naim CI-NAP 101 Mono Power Amplifier was developed as part of the Focal and Naim custom-integration ecosystem. Its power, connectivity, and operating modes are intended to complement Focal’s architectural speakers while remaining flexible enough for a broad range of compatible audio systems.
Yes. The CI-NAP 101 is designed to support traditional low-impedance loudspeakers as well as 70V and 100V distributed speaker systems. This flexibility makes it suitable for home theaters, whole-house audio, hospitality, commercial installations, and outdoor audio applications.
Absolutely. The stereo RCA loop-through outputs allow the input signal to be passed to additional amplifiers, making it easy to build larger multi-channel or multi-zone systems.
Yes. With up to 800 watts into 4 ohms and support for loads down to 2 ohms, the amplifier is well suited for many passive architectural and in-wall subwoofer applications when paired with compatible speakers.
Yes. The CI-NAP 101 includes signal sensing that automatically wakes the amplifier when audio is detected. It also enters standby after approximately 20 minutes without an input signal to reduce power consumption.
