Quam Nichols Company 4C3PAB Passive Loudspeaker

Product Description

The QUAM NICHOLS COMPANY 4C3PAB is a passive loudspeaker featuring a square frame construction. Passive loudspeakers require an external amplifier to drive them and contain no built-in amplification circuitry. The square frame design allows for straightforward mounting in ceiling tile grids, wall panels, or custom enclosures. This unit is suited for installation by audio-visual contractors, electricians, or low-voltage technicians working on paging, background music, or public address systems.

The 4C3PAB is appropriate for use in commercial and light commercial environments where distributed audio is required. Typical applications include office spaces, retail locations, schools, and similar facilities that use centralized amplifier-driven speaker systems. The square frame format is a common fit for lay-in ceiling grid installations as well as surface-mount applications.

Key Features

• Passive design compatible with external amplifier-driven distributed audio systems
• Square frame construction suited for ceiling grid or panel mounting
• Single-unit packaging for straightforward inventory and installation

Compatibility

Designed as an OEM-style replacement or new-install passive loudspeaker for use in amplifier-driven distributed audio and paging systems.

Installation Notes

Installation should be performed by a qualified low-voltage technician or licensed electrician in accordance with applicable NEC requirements for audio signal wiring. Disconnect and de-energize the amplifier system before making any speaker connections. Verify amplifier impedance requirements match the speaker load before connecting. Secure the square frame properly to the mounting surface to prevent vibration and ensure consistent acoustic performance.
