Power to Spare With a power rating of 50 Watts per channel at 8 Ohms from 20Hz to 20kHz with less than .05% THD, the MA-362 will drive virtually any appropriate loudspeaker to room filling volume. Power into 4 Ohms is 75 Watts per channel and bridged operation provides an impressive 150 Watts per channel into 8 Ohms.
MA-362 PRODUCT DESCRIPTION Installation Flexibility Ease of installation, a hallmark of all Audioaccess products is maintained in the new MA-362. An external speaker termination board allows advance termination of loudspeakers. At final installation, simply plug the speaker termination board onto the rear panel of the amplifier.

Thermal Protect FLASHING RED 1 or more channels has become inoperative YELLOW ™ AC P (Push button switch) OWER WITCH When the switch is depressed (in) power is supplied to the MA-362. When the switch is out, the unit is off.
Trigger Settings The MA-362 channels can be configured for a variety of sources. Each zone (L and R channel) of the amp can be triggered O in three different ways as listed below.
DESIGN CONSIDERATIONS & PHYSICAL INSTALLATION Channel Output The MA-362 channels can be configured in different ways to allow for use in various installation applications. In most cases the channels would be run in stereo, but should the need arise, the MA-362 can be configured for MONO output to work in an area where the speakers are spread apart, or the channels can be bridged for more power output.
Section 3 Channel Configuration Each channel of the MA-362 can be configured for different signal feeds, turn on source and output. Read through the following information before configuring the amplifier. Input Signal DESCRIPTION SWITCH SETTING MODE Input Local Channel is fed directly from the inputs for that Zone.
