1、 AUDIOACCESS MA-361/MA-361CP TWELVE CHANNEL DIGITAL 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-361 Twelve Channel Digital Amplifier designed, engineered and manufactured by Madrigal in

2、 Middletown, CT represents the product of over two years of research and development. As the inventor of the 12 channel amplifier category, Audioaccess has reinvented this category with the introduction of the MA-361. The goals for the MA-361 were clear: high power, low distortion, quiet, cool opera

3、tion, outstanding sonics and ease of installation, when used not only in Audioaccess systems, but also with other home and commercial audio distribution systems. The trend towards higher quality and larger speakers for custom installed applications has created a need for this amp. We believe you wil

4、l agree that the MA-361 is the first in an entirely new class of twelve channel amplifiers. Unique features The main features of the MA-361 include a conservative power rating of 100 Watts per channel into 8 Ohms from 20Hz- 20kHz with all channels driven at 93% efficiency. This amazing efficiency no

5、t only minimizes power consumption, it also runs surprisingly cool. Other unique features include programmable 7-band graphic EQ (set by the installer via PC) for each zone and optional plug-in stereo Volume/Tone Control Modules, which pro-vide volume control in Expansion rooms/sub zones within an A

6、udioaccess system or another RS-232 based control system. The modular layout permits the dealer to easily replace individual amplifier modules should service ever be required. An external speaker termination board can be ordered in advance to allow termination of loudspeakers before the amplifier is

7、 delivered for final installation. At final, simply plug the speaker termination board onto the rear panel of the amplifier. Other features To make the amplifier specifically attractive for use in whole-house audio distribution, we have included specific features to ensure reliable and easy installa

8、tion. Signal sensing and voltage triggers activate the main power in each stereo zone of amplification. Dip switches on the rear-panel configure the MA-361 for use in either mono or stereo operation. A simple bussing scheme allows audio signals to be routed into a single zone, selected zones, or all

9、 areas. 7-Band Graphic Equalization The MA-361s 7-band graphic equalization capabilities allows the installing dealer to custom tailor the sound in each zone to compensate for the different room acoustics throughout a residence, maximizing the performance of each pair of speakers. This is accomplish

10、ed by using the Audioaccess Installation Manager Software application (or stand-alone application) running on the dealers PC or laptop. Signal Sensing and Voltage Triggers The signal sensing capabilities of the MA-361 ensure that the amplifiers for a given zone are only powered on when a particular

11、area is active, saving on energy consumption. Voltage triggers allow the MA-361 to automatically turn on accessory items such as a fan, or a separate device when either the amplifier or a designated zone is activated. Volume/Tone Control Modules Optional Volume/Tone Control Modules, which plug into

12、available slots inside the amplifier, provide the ability to supply high power at very low distortion levels to expansion rooms within the multi-room system. The user may control the volume in rooms with Audioaccess keypads and touchscreens, or by using ANY other touch screen/control systems. A tota

13、l of 6 Volume/Tone Control Modules may be installed in the MA-361. Flexible Installation Capabilities The MA-361 is designed for use with Audioaccess systems, as well as other Multi-room or RS-232 based systems. The unit is programmed with the proprietary Installation Manager application when it is

14、used with other Audioaccess Multi- Room components. Configuration settings are downloaded from a Windows PC or laptop via the RS-485 communication port on the MA-361. When used with other RS-232 based systems, a separate application is available, which downloads amplifier configuration settings via

15、the RS-232 port on the MA-361CP version. Summary The MA-361s combination of power capabilities, sonic quality, features, programming ease, installation flexibility and serviceability clearly sets the new standard for amplifiers within the multi-room category.

17、byte-wide (x8) data appears on DQ7-DQ0. This device is designed to be programmed in-system using only a single 3.0 volt VCC supply. No VPP is required for write or erase operations. The device can also be programmed in standard EPROM programmers. This device is manufactured using AMDs 0.32 m process

18、 technology, and offers all the features and ben- efits of the Am29LV200, which was manufactured using 0.5 m process technology. In addition, the Am29LV200B features unlock bypass programming and in-system sector protection/unprotection. The standard device offers access times of 55, 70, 90 and 120

19、ns, allowing high speed microprocessors to operate without wait states. To eliminate bus contention the device has separate chip enable (CE#), write enable (WE#) and output enable (OE#) controls. The device requires only a single 3.0 volt power supply for both read and write functions. Internally ge

20、nerated and regulated voltages are provided for the program and erase operations. The device is entirely command set compatible with the JEDEC single-power-supply Flash standard. Com- mands are written to the command register using standard microprocessor write timings. Register con- tents serve as

21、input to an internal state-machine that controls the erase and programming circuitry. Write cycles also internally latch addresses and data needed for the programming and erase operations. Reading data out of the device is similar to reading from other Flash or EPROM devices. Device programming occu

22、rs by executing the program command sequence. This initiates the Embedded Program algorithman internal algorithm that auto- matically times the program pulse widths and verifies proper cell margin. The Unlock Bypass mode facili- tates faster programming times by requiring only two write cycles to pr

23、ogram data instead of four. Device erasure occurs by executing the erase command sequence. This initiates the Embedded Erase algorithman internal algorithm that automatically preprograms the array (if it is not already programmed) before executing the erase operation. During erase, the device automa

24、tically times the erase pulse widths and verifies proper cell margin. The host system can detect whether a program or erase operation is complete by observing the RY/BY# pin, or by reading the DQ7 (Data# Polling) and DQ6 (toggle) status bits. After a program or erase cycle has been completed, the de

25、vice is ready to read array data or accept another command. The sector erase architecture allows memory sectors to be erased and reprogrammed without affecting the data contents of other sectors. The device is fully erased when shipped from the factory. Hardware data protection measures include a lo

26、w VCC detector that automatically inhibits write opera- tions during power transitions. The hardware sector protection feature disables both program and erase operations in any combination of the sectors of memory. This can be achieved in-system or via pro- gramming equipment. The Erase Suspend feat

27、ure enables the user to put erase on hold for any period of time to read data from, or program data to, any sector that is not selected for erasure. True background erase can thus be achieved. The hardware RESET# pin terminates any operation in progress and resets the internal state machine to readi

28、ng array data. The RESET# pin may be tied to the system reset circuitry. A system reset would thus also reset the device, enabling the system microprocessor to read the boot-up firmware from the Flash memory. The device offers two power-saving features. When addresses have been stable for a specifie

29、d amount of time, the device enters the automatic sleep mode. The system can also place the device into the standby mode. Power consumption is greatly reduced in both these modes. AMDs Flash technology combines years of Flash memory manufacturing experience to produce the highest levels of quality,

30、reliability and cost effective- ness. The device electrically erases all bits within a sector simultaneously via Fowler-Nordheim tunneling. The data is programmed using hot electron injection. 4Am29LV200B PRODUCT SELECTOR GUIDE Note: See “AC Characteristics” for full specifications. BLOCK DIAGRAM Fa
