Bridged mono mode combines the power of two channels into one loudspeaker. This results in twice the voltage swing, four times the peak power and just less than three times the full power of a single channel. This is because the coil is driven with positive voltage at one pole and an equivalent negative voltage at the other pole. So, if an 8 ohms load is connected in bridged mode, one channel shares one 4 ohms part of the load, and the other channel shares the other 4 ohms part. The power into 4 ohms from an MA200Q is 200W. So, the total bridged power into the 8 ohms load will be 2 x 200 = 400W.

6 INSTALLATION

6.1Mounting

The amplifier is two rack unit's high (2U) and weighs 13.2Kg (29lbs) and will mount in a standard EIA 19” rack. Amplifiers may be stacked directly on top of each other. There is no need for spacing between units. If it is the intention to fill a rack with amplifiers, we recommend racking is started from the bottom of the rack. It is also recommended that rear supports are used for amplifiers mounted in the middle of the rack, especially if used as part of a portable system.

6.2Cooling

Your amplifier uses a forced air cooling system to maintain a low and even operating temperature. All fan cooled MARTIN AUDIO MA Series amplifiers have front to rear cooling. Never try to reverse the airflow, as the amplifier needs a pressure chamber between the fans and heat sink, and this only operates in one direction of the airflow.

Make sure that there is an adequate air supply in front of the amplifier, and that the rear of the amplifier has sufficient space to allow the exhaust to escape. If the amplifier is rack-mounted, do not use covers or doors on the front or rear of the rack.

If the heatsink temperature rises too high, it’s sensing circuit will mute the hot channel. If the power supply overheats, another sensing circuit will mute all four output channels, until they cool down to a safe operating temperature.

For installations with a central cooling system, usually found in a dedicated rack room, it may be necessary to calculate the maximum heat emission. Refer to Power consumption on page 10. Remember! Never rack different makes of amplifier together that have opposing air flow characteristics.

6.3Operating voltage

WARNING!

A label just below the mains cable on the rear of the amplifier indicates the selected AC mains operating voltage. Connect the mains cable only to the AC source referred to on the label. The warranty will not cover damage caused by connecting to the wrong type of AC mains.

If the power plug is not appropriate for your country, it can be cut off and re-wired to a suitable connector in the following way:

BLACK or BROWN
