SAFETY INFORMATION

1. Parts that have special safety characteristics are identified by the symbol on schematics

or by special notes on the parts list. Use only replacement parts that have critical characteristics recommended by the manufacturer.

2. Make leakage current or resistance measurements to determine that exposed parts are acceptably insulated from the supply circuit before returning the unit to the customer. Use the following checks to perform these measurements:

A. Leakage Current Hot Check-With the unit completely reassembled, plug the AC line cord directly into a 120V AC outlet. (Do not use an isolation transformer during this test.) Use a leakage current tester or a metering system that complies with American National Standards Institute (ANSI) C101.1 "Leakage Current for Appliances" and Underwriters Laboratories (UL) UL6500 / UL60065 / IEC 60065 paragraph 9.1.1. With the unit AC switch first in the ON position and then in OFF position, measure from a known earth ground (metal waterpipe, conduit, etc.) to all exposed metal parts of the unit (antennas, handle bracket, metal cabinet, screwheads, metallic overlays, control shafts, etc.), especially any exposed metal parts that offer an electrical return path to the chassis. Any current measured must not exceed 0.5 milliamp. Reverse the unit power cord plug in the outlet and repeat test. ANY MEASUREMENTS NOT WITHIN THE LIMITS SPECIFIED HEREIN INDICATE A POTENTIAL SHOCK HAZARD THAT MUST BE ELIMINATED BEFORE RETURNING THE UNIT TO THE CUSTOMER.

B. Insulation Resistance Test Cold Check-(1) Unplug the power supply and connect a jumper wire between the two prongs of the plug. (2) Turn on the power switch of the unit. (3) Measure the resistance with an ohmmeter between the jumpered AC plug and each exposed metallic cabinet part on the unit. When testing 3 wire products, the resistance measured to the product enclosure should be between 2 and infinite MOhms. Also, the resistance measured to exposed input/output connectors should be between 4 and infinite MOhms. When testing 2 wire products, the resistance measured to exposed input/output connectors should be between 4 and infinite MOhms. If it is not within the limits specified, there is the possibility of a shock hazard, and the unit must be repaired and rechecked before it is returned to the customer.

CAUTION: The Bose® E4 Series II Business Music System contains no

user-serviceable parts. To prevent warranty infractions,

refer servicing to warranty service stations or factory service.

PRODUCT DESCRIPTION

E-4 Series II Business Music System

The Bose® FreeSpace® E-4 Series II Business Music System is an integrated four-channel digital signal processor and 400-Watt power amplifier for 70/100V business music applications.

The E-4 chassis provides a total of four source inputs (two Line In, one Mic/Line and one Mic/ Line/Page) to meet the needs of most business music installations. A Music on Hold (MOH) output is also provided for simple integration into a phone system.

As a single component, the chassis provides all of the processing and control features required for one to four zone business music applications. These features include:

• Auto Volume: When used with the optional FreeSpace Auto Volume Sense Mic, the E-4 system dynamically controls the program level in each zone so that the audio program material can always be heard, regardless of the background noise.

• Scheduling: Allows you to program the E-4 system for automated on/off and source selections according to time of day or day of week.

• Opti-Voice® Paging: Provides the appropriate sound level regardless of variations in speech projection.

• Source Leveling: Automatically compensates for variations in source input levels.

• Dynamic Equalization: Maintains tonal balance at all listening levels.

• Room Equalization: Provides easy adjustment of tonal balance in each zone.

• Limiting: Protects loudspeakers from unwanted transient power loads.

• Signal Router: Meets the demands of most four-zone systems, allowing for any input signal

to be routed to any of the amplifier outputs.

• RS-232 Connection: Provides easy interfacing to your PC.

• Contact Closure Input: Allows remote power sequencing.

The integrated 400-Watt power amplifier features a patented power-sharing technology which allocates power to each output.

For example, if you have a two-zone system that requires 5 Watts in zone 1 and 395 Watts in zone 2, the FreeSpace E-4 Series II system distributes the power based on those needs.

The E-4 Series II also includes an easy-to-replace memory module, which holds a design file and the current hardware configuration.

ELECTROSTATIC DISCHARGE SENSITIVE (ESDS)

DEVICE HANDLING

This unit contains ESDS devices. We recommend the following precautions when repairing, replacing or transporting ESDS devices:

• Perform work at an electrically grounded work station.

• Wear wrist straps that connect to the station or heel straps that connect to conductive

floor mats.

• Avoid touching the leads or contacts of ESDS devices or PC boards even if properly grounded. Handle boards by the edges only.

• Transport or store ESDS devices in ESD protective bags, bins, or totes. Do not insert unprotected devices into materials such as plastic, polystyrene foam, clear plastic bags, bubble wrap or plastic trays.

PART LIST NOTES

1. This part is not normally available from Customer Service. Approval from the Field Service

Manager is required before ordering.

2. The individual parts located on the PCBs are listed in the Electrical Part List.

3. This part is critical for safety purposes. Failure to use a substitute replacement with the

same safety characteristics as the recommended replacement part might create shock, fire and/or other hazards.

4. This part is referenced for informational purposes only. It is not stocked as a repair part. Refer to the next higher assembly for a replacement part.

AMPLIFIER MODULE REPAIR INFORMATION

The Amplifier / Power Supply PCB assembly, part number 278982-001, originally used in the E4 Series II amplifier is no longer available. This is due to the Tripath amplifier driver module going obsolete.

For amplifier board related failures in the E4 Series II, the amplifier module assembly used in the FreeSpace® 4400 amplifier must be used as a replacement part. This requires some minor modifications to the E4 II chassis and a kit of parts that includes adapter brackets, screws and an EMI gasket. The entire amplifier assembly, including the heatsink, must be replaced. Refer to service bulletin 278977-B2, located in the back of this manual as well as on the Bose® Service web sites at http://intranet.bose.com/tsg or http://serviceops.bose.com for more information.

Required Parts:

• FreeSpace 4400 Amplifier Module Assembly , Bose

part number 301391

• FreeSpace 4400 Amplifier Module adapter kit, Bose part number 311963

Note: This procedure cannot be used on any of the E4 Series I amplifier versions. In addition, it cannot be used on the E4 Series II Japan version, product code 036006.
