Product information

Description

The Monacor PA-312 is a mono PA mixing amplifier rated at 1 x 120 WRMS, intended for public address and basic sound reinforcement. It features fanless cooling for silent operation, multiple microphone and auxiliary inputs, a telephone input, screw-terminal speaker outputs and a line output. Front-panel controls include input/output level adjustments and a 2-way tone control for bass and treble. Channel 1 offers switchable 48 V phantom power and a priority circuit with adjustable automatic talkover for announcements. The unit fits a 482 mm (19") rack with the supplied mounting brackets and operates from 230 V AC.

Advantages

The PA-312 combines compact 19" rack compatibility with a fanless design to provide quiet, reliable operation in venues where low noise is important. It supports balanced and unbalanced microphone connections, offers telephone system integration and provides basic tone shaping and level controls for straightforward setup and operation. Its 120 WRMS output and modest distortion and noise figures make it suitable for background music and speech applications.

Suitable for

  • Background music in shops, cafés and small offices
  • Public address and simple announcement systems
  • Small meeting rooms and training spaces
  • Basic sound reinforcement in community halls and small venues

When it may not be suitable

This amplifier is intended for basic PA duties and modest power requirements; it is not designed for large venues or professional concert sound reinforcement. Systems requiring advanced DSP, multichannel mixing, high-power touring amplification or extensive input routing will find the feature set limited.

Key specifications

  • Output power: 1 x 120 WRMS
  • Channels: 1.0 (mono)
  • Total Harmonic Distortion (THD): 0.5%
  • Signal-to-noise ratio (SNR): 80 dB
  • Microphone inputs: 3 (one balanced), Mic 1 with priority and adjustable automatic talkover
  • Aux inputs: 2
  • Telephone input: 1 (for telephone systems with audio output)
  • Outputs: speaker screw terminals, 1 line output
  • Headphone output: 6.3 mm
  • Tone control: 2-way (bass and treble)
  • Phantom power: 48 V switchable on channel 1
  • Cooling: fanless (silent operation)
  • Power supply: 230 V AC, 50 Hz
  • Dimensions: 482 mm (19") rack with supplied brackets
  • Weight: 7.8 kg
  • Colour: black

How to use

Install the amplifier in a standard 19" rack using the supplied mounting brackets or place it on a stable surface. Connect microphones to the microphone inputs (use the balanced input when available for lower noise), connect source devices to the aux inputs or telephone input as required, and wire speakers to the screw-terminal outputs. Use the input and output level controls to set appropriate gain and the 2-way tone control to adjust bass and treble. If a condenser microphone is used on channel 1, enable the 48 V phantom power. Mic 1 priority and automatic talkover can be adjusted for announcement scenarios.

What to consider before purchase

  • Intended venue size and required output power — 120 WRMS suits small to medium spaces
  • Number and type of inputs needed (balanced mic input available on one channel)
  • Whether fanless operation is important for low-noise environments
  • Need for telephone system integration or headphone output
  • Rack-mount compatibility if integration into a larger system is planned

Usage recommendations

For clear announcements and background music, use balanced microphone connections where possible, set input gains conservatively to avoid clipping, and apply modest tone adjustments to suit room acoustics. Enable phantom power only when using condenser microphones and ensure secure speaker wiring to the screw terminals.
