NAD CI PA4-60 Power Amplifier Module
Compact four-channel NAD power for installed zones where the amplifier should disappear but the sound should not.
When Small Rack Space Still Needs Real Amplification
Some installed systems need flexible power without dedicating a large rack space to every zone. The risk is choosing a compact amplifier that saves space but makes the music feel light or ordinary.
Audio Two uses compact CI amplification when the room layout, speaker plan, and rack design call for efficiency without treating sound quality as an afterthought.
Four Channels of DirectDigital Power in a Compact CI Module
The NAD CI PA4-60 is a compact four-channel power amplifier designed for custom installation and distributed audio systems. It provides 240 watts of continuous power into 8 ohms and uses NAD DirectDigital amplification, with Dynamic Power Management allowing the module to be configured as a higher-power two-channel amplifier when the system calls for it.
Its one-third-width, 1U chassis gives Audio Two more flexibility in racks, cabinets, and compact equipment locations. That is useful when the system needs clean hidden power for selected zones without making the hardware footprint larger than the space requires.
What the Specs Won't Tell You
Efficiency Does Not Have to Feel Thin
The CI PA4-60 is built to keep rack space efficient while still giving speakers a NAD amplification platform behind them. Audio Two can use it where compact size matters but the room still deserves weight, clarity, and control.
The Same Module Can Serve Different Zone Plans
Four-channel operation supports distributed layouts, while Dynamic Power Management allows higher-power two-channel use. That gives Audio Two more freedom to match the amplifier configuration to the speaker and room requirement instead of forcing every zone into the same pattern.
Hidden Hardware Can Stay Serviceable
The compact CI module format helps the rack stay organized when space is limited. Efficient thermal management also matters because hidden technology should be reliable after the room is finished.
The Audio Two Verdict
The CI PA4-60 is the practical power module in this NAD CI group. It is not the control layer and it is not the streamer; it is the compact hidden amplifier Audio Two can place behind the right source, control system, and speaker plan.
That makes it valuable when the design needs clean rack density, flexible channel use, and sound that feels more intentional than a generic utility amplifier.

Why Choose Audio Two
This is custom-install infrastructure for a designed Audio Two system. Audio Two plans the zone layout, matches the speakers and sources, builds the rack, configures BluOS, Control4, or AVA control as the project requires, and tunes the system so the technology stays hidden while the sound feels premium in the rooms where it matters.
