The Monacor PA-324 is a 240W Mono PA Mixing Amplifier with 100V and 70V line operation, featuring three microphone inputs, two stereo line inputs, a dedicated telephone input and adjustable automatic talkover — a versatile, rack-mountable solution for public address and background music installations.

The Monacor PA-324 is a 240W mono PA mixing amplifier designed for professional public address and background music applications, combining flexible mixing capability with robust 100V line amplification in a single rack-mountable unit. With three microphone inputs — one of which is a balanced combo XLR/jack input — two stereo line inputs and a dedicated telephone input for integration with telephone paging systems, the PA-324 provides the input flexibility needed for retail, hospitality, educational and commercial installations requiring background music, announcements and paging from multiple sources.

Flexible Input Configuration & Priority Function

Mic/Line 1 features adjustable input sensitivity alongside a priority circuit and adjustable automatic talkover function — automatically ducking background music or other input sources when an announcement is made on this channel, ensuring paging messages are always heard clearly above other audio. The remaining two microphone inputs and two stereo line inputs provide ample connectivity for additional microphones, music sources and playback equipment, with individual input and output level controls for precise system balancing. 48V phantom power can be activated as required on channel 1 for use with condenser microphones.

100V Line & Low Impedance Output Flexibility

The PA-324 delivers 240W of continuous power at 100V and 70V line output, as well as 240W at 4 Ohm, 120W at 8 Ohm and 60W at 16 Ohm for direct low-impedance speaker connection — providing the flexibility to drive either distributed 100V line speaker systems or conventional low-impedance speakers directly from the same amplifier. Speaker outputs are connected via secure screw terminal contacts, and a dedicated line output allows the signal to be passed to additional amplifiers or recording equipment.

Tone Control & System Integration

A 2-way tone control on the output provides ±10dB of bass adjustment at 100Hz and ±10dB of treble adjustment at 10kHz, allowing the overall tonal character of the system to be tailored to the installation environment. With a frequency range of 50Hz to 16kHz and a signal-to-noise ratio of 66dB (mic) and 80dB (aux), the PA-324 delivers clean, reliable audio performance suitable for professional PA applications.

Rack-Mountable Design

The PA-324 is supplied with mounting brackets for installation in a standard 482mm (19") rack, occupying 2U of rack space — making it a practical and space-efficient addition to any PA equipment rack or installation cabinet.
