The Public Address Amplifier System with Flexibility Built-in

The Mitre range is now a well-proven group of products. With an excellent track record for reliability, Mitre can accommodate all your PA needs ~ integrating several uses at the touch of a button if required. The user-friendly Mitre range comes with several built-in safety factors and is designed to provide a high degree of flexibility as well as quality and reliability. Mitre was designed at our Sussex headquarters and is now at the heart of countless PA systems.
The induction loop amplifier (M10L) may be used as a ‘stand alone’ unit, although it is normally ‘slaved’ from the main PA system via the auxiliary input.

The Mitre range includes:

Mixer amplifiers –  120 Watt (M2120E) and 300 Watt (M2300M).

Slave amplifiers – 300 Watt (M2300S).

Induction loop amplifier (M10L).

All Mitre amplifiers are protected from overheating by using sensors attached to the output stage heatsink, especially important where amplifiers are rack mounted and used for continuous
broadcast – such as for background music. Should the amplifier exceed its safe operating temperature it will automatically reduce its volume to a safe level, thus allowing it to cool.  Once cooled it will operate normally without manual resetting. The 300 Watt versions are further protected by use of temperature controlled internal fans.

Mixer Amplifier ~ 120 Watt M2120E

M120E is an integrated 5 input 120 Watt free standing or rack mountable amplifier powered from a 230 Volt AC power supply. Each of the 5 inputs has its own volume, bass and treble controls.

5 inputs which have their own volume, bass and treble controls.

An output level 4 bar LED display indicates at 5%, 25%, 50% and 100% power.

230 Volt AC supply.

Both 100V line or low impedance are selectable via a Neutrik Speakon Connector.

Optional OPT401 digital recordable, message can be up to 60 seconds in length, unmonitored message module.

Free standing or rack mountable (use M2RACK).

Optional OPT 33 chime module.

Optional Graphic Equaliser.

2 U high.

Mixer Amplifier ~ 300 Watt M2300M

 Four balanced microphone/line universal inputs.

Each universal input has the option of cascade priority, phantom power, chime and volume restoration/busy.

XLR or screw terminations.

Built-in one, two or three note chime with pre-set volume control.

Built-in alarm tone generator with pre-set volume control. Tones are adjustable.
 
A continuous 900 Hz tone or continuous pips can be configured, making it suitable for class change, start and stop work, etc.

Each universal input has an ‘input live’ indicator.

Master volume, treble and bass controls.

Four zone relay selector as standard.

Internal option socket. Can be used to add frequency equaliser, etc.

Music mute facility, which allows for music to be totally muted or ‘ducked’ to a
pre-set level, when paging operated.

Remote music mute DC input from time clocks, etc.

Output stage protected by thermal shut down in the event of an unsuitable load.

Auxiliary stereo music input (internally mixed) to accept tuners, CD players or tape decks.

Power amplifier input phono connector to enable two amplifiers to be connected
together to provide ten inputs.

24V DC output.

Slave Amplifier ~ 300 Watt M2300S

Two 0dBM balanced line inputs which have selectable priority and rear mounted
independent gain controls.

Priority selectable by DIL switch.

 Internal option socket. Can be used to add frequency equalisers, etc.

 Output level indicator.

 Busy input indicator.

 Output stage protected by thermal shut down in event of unsuitable load.

 30V 1.5A output for powering mixers etc.

The M10L is an audio frequency induction loop amplifier designed to drive loops at up to 10A peak current. A tone control, accessible only from the underside of the amplifier, allows the installer to adjust the frequency response of the amplifier to optimise the performance of the system. An induction of the peak current flowing in the loop is provided by the bar graph display on the front panel, along with limiter and protection indicators.

By selection of a slide switch (located on the rear of the unit) a 1KHz test tone is enabled to assist in the setting up of the loop output. The test tone may also be used to conduct periodic testing of the loop installation.

 One M10L is capable of providing an induction loop for a 200 square metre area.

 One balanced microphone input, one auxiliary unbalanced line input.

Plug-in Option:

MIM16 ~ auxiliary to balanced line converter card. By inserting this card onto the connector inside the rear of the amplifier enables the operator to convert the existing unbalanced auxiliary input into a balanced 80mV 20K Ohm line input.
