AUDIOACCESS MA-362 TWELVE CHANNEL AMPLIFIER PRELIMINARY SERVICE MANUAL Harman Consumer Group 250 Crossways Park Dr. Woodbury, New York 11797 RadioFans.CN 收音机爱 好者资料库FEATURES The Audioaccess MA-362 Twelve Channel Amplifier represents a high value approach while providing twelve channels of clean amplifier power for multi-room system applications. 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 in-wall loudspeaker to room filling volume. Power into 4 Ohms is even more impressive at 75 Watts per channel. All channels may be bridged if additional power is required. Cool operation is ensured with a design incorporating heat sinks, flow through ventilation and low-noise fans. After a series of careful evaluations and tests, Madrigal has chosen to implement a conservative and proven design philosophy with the MA-362 with the added benefit of improved sound quality and long component life. Power for each channel is delivered by a pair of high current output transistors capable of delivering over 200 watts, much higher power than the rated 50 watts per channel. The output transistors for each channel can handle 12 amps of current. At rated power, the MA-362 draws 2.5 amps of current, ensuring ample safe operating area headroom and reliable performance. Zone Muting Control Each pair of channels is controlled by a three-position Trigger Source switch to select signal sensing, voltage trigger or link (to the trigger signal of the zone to the immediate left). Unique Input Bussing A two position Signal Link switch is also provided for each zone. This allows assignment of direct input to the zone, or to share the source utilized by the zone to its left, eliminating the need for Y-cords to distribute common inputs to multiple zones. Installation Flexibility Ease of installation, a hallmark of all Audioaccess products is maintained in the new MA-362. An external speaker termination board can be ordered in advance to allow termination of loudspeakers before the amplifier is delivered for final installation. At final, simply plug the speaker termination board onto the rear panel of the amplifier. Summary The MA-362 features, performance and reliability make it the perfect amplifier choice for a wide variety of multi-room audio system applications.
