PowerMatch® power amplifiers deliver concert-quality sound for a wide variety of fixed-installation sound reinforcement systems and provide class-leading efficiency, sound quality, and reliability.
Two documents are available to assist with amplifier installation and configuration. This document delivers detailed installation and standalone configuration information. A separate document, the ControlSpace® DesignerTM Software Guide (downloadable from pro. Bose.com), provides detailed instructions on how to use ControlSpace Designer software to fully configure, monitor, and update PowerMatch amplifiers. For network version amplifiers, Designer software provides additional network setup, control, and monitoring capabilities.
Information furnished in these guides is intended to help professionals install and set up the product, but does not include all details of design, production, or variations of equipment. Nor does it cover every possible situation that may arise during installation, operation, or maintenance. If assistance is required beyond the scope of these documents, please contact your local Bose Representative or Technical Support specialist.

Product Features
· PowerMatch amplifier series
Four amplifier models provide multiple channel and power options to satisfy the needs of almost any audio installation. Models include options for 4 or 8 channel versions and 250 or 500 watt per channel power levels. Additionally, network versions add control and monitoring functionality over standard Ethernet networks.
· Dual Feedback Loop System
Proprietary design combines Class-D efficiency with a dual current and voltage feedback loop circuit that continuously monitors and controls both the current and voltage delivered to the loudspeaker load. This combination allows the amplifier to consistently deliver the widest possible dynamic range, frequency response, and lowest possible distortion, independent of power level and load impedance.
· QuadBridgeTM Output Configuration
Each loudspeaker output terminal can be configured as Mono, V-Bridge, I-Share or Quad, allowing the total available power of the amplifier bank to be allocated to one or more output channels. V-Bridge and Quad modes can drive either low-impedance or 70/100V loads. Configuration of the loudspeaker output can be accessed from either the front panel of the amplifier or using ControlSpace Designer software.
· PeakBankTM Power Supply
Regenerative 4-quadrant power supply with fast-tracking Power Factor Correction (PFC) supports high efficiency while delivering sustainable and repeatable low frequency response.
· Integrated DSP
A configurable fixed-architecture DSP provides multiple EQ stages, crossovers, delays, limiters, and matrix mixing. While PowerMatch can drive nearly any loudspeaker for the installed sound market, pre-loaded loudspeaker EQs and limiting presets for Bose loudspeakers provide an additional layer of simplified setup and premium sound. Amplifier models PM8500 and PM4500 feature power levels and array EQ features ideal for use with RoomMatch® array module loudspeakers and subwoofers.
· ControlSpace® DesignerTM Software Setup
All models offer front panel USB connectivity for Bose ControlSpace Designer software programming, with network versions adding Ethernet network setup, control, and monitoring.
· Front Panel User Interface
Combined front panel LCD and user controls provide useful visual information and access to a subset of amplifier settings sufficient for basic amplifier output configuration and status/fault monitoring. A convenient panel lock can be set to prevent access to unauthorized users.
· Network Control and Monitoring
Network versions support a set of remote monitoring and fault reporting capabilities via the rear panel RJ45 Ethernet connection and Bose ControlSpace Designer software. A fault reporting and control protocol using Serial over Ethernet allows third party control and monitoring systems to communicate easily with one or many PowerMatch amplifiers.
· Load Sweep Tool
Using ControlSpace Designer software, the amplifier can measure the load impedance of each low impedance-configured output for system diagnostic and documentation purposes. The load measurement can be stored inside the amplifier and recalled as a reference curve for future comparisons to determine if the system is still operating as expected.
· Digital Expansion Slot
Optional digital cards expand the input capabilities of PowerMatch® amplifiers, enabling the amplifiers to receive digital audio from Bose ESPLink-equipped devices and popular digital audio networks.
· Auto-Standby / Auto-Wake
Energy saving feature that allows PowerMatch amplifiers to automatically go into a lower power Standby Mode when audio signal falls below a set threshold, and wake up when audio signal is above threshold. All parameters, including time and audio detection levels are adjustable from within ControlSpace® DesignerTM software.

Ideal for use with RoomMatch® array module loudspeakers

RoomMatch loudspeakers connect and configure easily to PM8500 and PM4500 amplifiers. Built-in loudspeaker and array EQs together with suitable output power ratings and optimized loudspeaker limiting/protection make these amplifiers ideal for use in designs with RoomMatch array module loudspeakers.

Interfacing with ControlSpace® engineered sound processors

PowerMatch amplifiers are designed to be used independently or in any system with most professional audio processing equipment and loudspeakers. However, there are unique advantages to using PowerMatch with Bose ControlSpace ESP engineered sound processors. These processors enable multi-channel input options, mixing, routing, processing, and distribution capabilities ­ all using a single configuration tool, ControlSpace Designer software.

Using a Bose ESPLink connection, a ControlSpace ESP engineered sound processor can route 8 digital audio channels to multiple PowerMatch amplifiers for low latency in-rack audio distribution. For wiring digital audio between racks or for use in larger distributed systems, Audio over Ethernet expansion cards are also available for use with the PowerMatch and ControlSpace ESP processors.

Rack Mounting
PowerMatch amplifiers are designed to fit standard 19-inch (48 cm) rack equipment, occupying 2 rack-units (RU) in height, requiring a mounting depth of 21 inches (53 cm) from the front rack rail. Use four fasteners with washers (not supplied) to mount the amplifier front panel rack ears to the equipment rack rails. Rack-mount tabs are also provided on the rear of the chassis to secure the amplifier using rear rack mount ears (not provided). Rear rack mounting is recommended in cases when pre-assembled racks with amplifiers are transported to installation venues.
Ventilation
PowerMatch amplifiers are designed to operate under a wide range of conditions, with continuous operation up to 104° F (40° C) ambient temperature. To ensure safe operation, the front and rear airflow vents should never be blocked. Air flows into the front of the unit and exits the rear vents. The internal fans automatically increase speed when the amplifier is generating more heat. Should the unit exceed safe operating temperature, a gradual reduction of gain will automatically be applied for thermal protection. If the automatic gain reduction does not reduce operating temperatures to safe conditions, the unit will mute all outputs and the red FAULT LED will illuminate on the front panel.
AC Mains Outlet Requirements
PowerMatch amplifiers feature an efficient, universal switch-mode power supply with fast-tracking Power Factor Correction (PFC) and can operate with AC mains line voltages from 100 to 240 volts at 50/60 Hz. With typical music program material, amplifier model PM8500 provides full rated power from a single 20-amp, 120V (common in USA) AC mains outlet, or single 16-amp, 230V (common in Europe) mains outlet. The mains circuit requirement for models PM8250, PM4500, and PM4250 is lesser, as full rated power can be achieved using a 15-amp, 120V (USA) AC mains outlet or a 10-amp, 230V (Europe) AC mains outlet.
High-power amplifiers draw large amounts of current from the AC mains. Use of extension cords to power the amplifier could introduce significant impedance and a resulting voltage drop on the mains that may interfere with normal operation of the amplifier.
In countries like Japan where 100V AC mains are used, the following guidelines will be helpful to ensure optimal performance:
· Ensure a minimum of 100V AC at the amplifier plug when the amplifier is idle.
· Use a dedicated mains circuit for each amplifier.
· Locate the amplifiers as close as possible to the mains outlet.
· If used, extension cords should be 14 AWG (2 mm2) or larger, and less than 6.6 ft (2 m) in length.

Mount the amplifier into the rack 3. Connect power cable and retaining clip 4. Turn on amplifier 5. Enable Standby Mode from the front panel of the amplifier (See page 29.) 6. Configure amplifier (use front panel or ControlSpace® DesignerTM software) 7. Wire input connection from source device(s) 8. Wire output connectors to speakers 9. Disable Standby Mode 10. Connect Fault Notification Output to management system or device (optional) 11. Clear alarms (See page 30.) 12. Test system Power (Mains) Connection Power connection is made using the included IEC power cord. The amplifier also includes a retaining clip to help secure the power connection to the amplifier. To install, place the retaining clip toward the center of the amplifier, plug in the IEC power cord, then swing the retaining clip so it locks behind the IEC connector.
Figure 4. IEC Connector retaining clip in place.

Standby Mode
Enabling Standby Mode decouples the amplifier section from the loudspeaker output. In this state the product also consumes less power. Standby Mode can be entered manually from the front panel using the following steps:
MAIN MENU > UTILITY > STANDBY MODE > press ENTER STANDBY
While in Standby, front panel options and loudspeaker output configurations can be changed without directly affecting the loudspeaker load.
Standby Mode can be automatically entered and exited using the Auto-Standby /Auto-Wake function as a method to help reduce energy usage during times when audio is not required. Refer to the ControlSpace Designer Software Guide for details on this feature.

Wiring Input Connectors
The balanced line-level analog inputs utilize 3-pin terminal block connectors (Phoenix Contact® #1776168, supplied). Terminal descriptions are printed directly on the connectors for convenience. For balanced inputs, strip the wire ¼ inch (6 mm) and connect to the respective positive, negative, and ground terminals as indicated on the connector and in Figure 5. Tinned wires are not recommended. For unbalanced inputs, the connector should be wired with the negative and ground/shield terminals, connected with a jumper wire (not supplied). To reduce the occurrence of ground loop noise, it is recommended that the input cable shield be joined with the ground terminal at only one device – at the source output connector or at the amplifier input connector. You can use the supplied tie-wraps to help secure the input cables.

Wiring Output Connectors
PowerMatch® amplifiers feature QuadBridgeTM technology which provides the flexibility to reconfigure each amplifier output. On a single output connector, amplifier power can be allocated between 1 and 4 output channels for low impedance loudspeaker loads or up to 2 output channels for high impedance (70V and 100V) loudspeaker loads. A combination of high/low impedance loads and a mix of power levels can be configured through the front panel interface or using ControlSpace® DesignerTM software. The following table describes the behavior of the four available output modes:

Mode Mono V-Bridge I-Share Quad

Description Each channel operates independently, and will drive 2 to 16 loads Channel pairs are combined to deliver 2x voltage and will drive high impedance (70V or 100V) and 4 to 8 loads Channel pairs are combined to deliver 2x current, and will drive 2 loads Two channel pairs are combined to deliver 2x voltage and 2x current while driving high impedance (70V or 100V) or 4 loads

4-channel amplifiers (PM4500, PM4250) use a single loudspeaker output connector. 8-channel amplifiers (PM8500, PM8250) split total amplifier power across two output connectors. In the case of the PM8500 which has a maximum rated power of 4000 watts, power is split where 2000 watts is available at each output connector.
Each loudspeaker output utilizes a high-current, 8-pin locking terminal block connector (Phoenix Contact® COMBICON® Part #1778120, supplied) that accept cables from 10 to 24 AWG (5.3 – 0.2 mm2) in diameter. Note: Use Class 2 wiring for speaker connections.
To wire the output connector: 1. Strip the insulation off each speaker wire to expose 3/8″ (10 mm) of bare conductor. 2. Insert each wire into the correct terminal on the block connector. Use a small Phillips size 1 (or appropriate) screwdriver to secure
the wire. 3. Firmly press the block connector into the receptacle on the amplifier until the left and right latches snap into place.

To detach the block connector from the amplifier, slide the two orange release tabs toward the amplifier to release the locking tabs. Once released, pull the terminal block connector from the amplifier.
Warning: While the amplifier does self-protect under most improper output conditions, misconfiguration of loudspeaker mode and incorrect connection of loudspeakers could damage connected loudspeakers and/or amplifier.

Note: Configure the output mode of the amplifier before connecting loudspeakers. See page 21 for details on front panel configuration. Carefully follow the proper connection method for the selected output configuration.
The wiring of the connector varies by amplifier output configuration. The output terminal assignments for Mono (single channel) and V-Bridge configurations are printed on the rear panel of the amplifier.
The following graphics illustrate wiring examples for the different output configuration modes. Mixed combinations of Mono, V-Bridge, and I-Share modes are possible from one output block.

Setting the Limiting Function for use with 3rd Party Loudspeakers
The Limiting function allows you to restrict, per channel, the maximum signal level to the loudspeaker. Here are some simplified steps to aid in setting the limiter function.
1. Locate the technical data specification sheet for the 3rd party loudspeaker. 2. Configure the amplifier outputs (MAIN MENU < CONFIG < OUTPUT CONFIG) to drive the loudspeaker at or beyond the rated
power of the loudspeaker indicated in the loudspeaker’s data specification sheet. 3. Select the proper EQ (flat or custom EQ for non-Bose loudspeakers) from MAIN MENU < DSP < SPEAKER PRESETS.
4. Using the manufacturer’s loudspeaker specification sheet, calculate the limiter RMS voltage using the loudspeaker’s continuous power rating using the following formula:
RMS Voltage = Square Root (rated power of the loudspeaker x loudspeaker impedance). 5. In the MAIN MENU < DSP < LIMITING menu, select the appropriate output channel and set the RMS voltage to the loudspeaker’s
RMS voltage. 6. Set the Peak value to 1.4 to 2 times the RMS voltage. Note the maximum RMS and Peak voltage values below in Figure 11 when
setting these parameters.
7. Reference loudspeaker data specifications or consult with loudspeaker manufacturer to obtain optimal settings for Attack and Release parameters.

Maintenance Operations
Updating Firmware and Speaker EQ Presets Each PowerMatch® amplifier contains two user-updatable files: Firmware and loudspeaker EQ files. These files can both be updated from ControlSpace® DesignerTM software using a PC connected to either the USB connection on the front panel of the amplifier, or, in the case of a network version amplifier, an Ethernet network connection (use shielded CAT5e cable only). The firmware version of the amplifier can be viewed directly on the front panel by selecting MAIN MENU < UTILITY < FIRMWARE VERSIONS. The version of both firmware and EQ files can be viewed in ControlSpace Designer software. Please refer to the ControlSpace Designer software user’s guide available on pro.Bose.com for software installation instructions. From within ControlSpace Designer software, firmware and EQ file information can be found in the Hardware Manager. To launch this feature, click Hardware Manager in the System Menu or click the Hardware Manger button in amplifier properties window.
Figure 14. Launching the Hardware Manager

Upon launching the Hardware Manager, the software performs a scan to determine the devices on the network and adds them to the Device List. Select the Firmware Update tab (Figure 15) to view the firmware file status, and select the EQ Update tab (Figure 16) to view EQ file status.

About the Alarm Log and Fault Indicator
The PowerMatch® amplifier monitors operating temperature, power supply status, amplifier status, open and short wiring, and additional conditions for issues.
When issues are detected, the last 50 issues are stored in the amplifier in an internal log found by accessing MAIN MENU < UTILITY < ALARM LOG from the front panel.
Information from the alarm log can also be viewed using ControlSpace® DesignerTM software. In systems where ControlSpace Designer software is actively connected, either via USB or Ethernet, the time and date of the alarm condition is appended to the alarm log entry on the PC. Locally stored alarm information has no time/date information, but is shown in order of last occurrence.
Critical internal system-related issues are always considered faults and will trigger the fault-notification output and the Fault LED on the front panel. However, you have the ability to select whether certain conditions are faults using ControlSpace Designer software. Refer to the ControlSpace Designer software documentation for details on how to view and manage alarms.
The table below lists the possible fault conditions and recommendations on how to address these conditions. Variables are shown as “x”, X”, or “y”, but will be displayed as values or part numbers in the actual alarm text string.

Troubleshooting

Problem No power
Power is on, but no sound
Power is on, sound is low
Unnatural sound Front panel is locked out, combination is lost Fault LED is lit USB is connected to PC but not found by ControlSpace Designer software
Ethernet is connected to network but amplifier is not found by ControlSpace Designer software (PowerMatch network versions only)

Possible Solution
· Turn on power switch. Clip, Limit, and Signal LEDs should stay lit for approximately the first 15 seconds, after which the amplifier should be fully ready for operation. The amplifier’s LCD screen will show the firmware version screen after about 10 seconds, then revert to the operating screen.
· Check power cable, ensure retaining clip is in place. · Check mains circuit.
Check the LCD screen for output meter activity. If no signal activity, check the following:
· Check the Input Meter screen for presence of signal. If no signal, fix source or cabling. · Ensure that input and output signals are not muted. · Check that Input Routing is configured properly. · Check that Input Source is set to appropriate signal type (analog or digital). · Check that Output Attenuate is not set too low. · Make sure loudspeakers are wired correctly to output connectors. · Check that Output Configuration is set correctly. · Check that Standby Mode is not active.
· Verify source level by monitoring Input Meter. Check that Input Routing and Input Sensitivity are set for optimal gain. · Check that Output Attenuate is not set too low. · Make sure loudspeakers are wired correctly to output connectors. · Check that Output Configuration is set correctly. · Check that Limiting parameters are set properly.
Check that all DSP functions (EQs, Limiter, Band Pass, Delay) are set appropriately.
Use ControlSpace® DesignerTM software to connect to the amplifier and unlock the front panel.
Refer to Figure 18, “Fault Conditions” on page 37 for alarm conditions and potential solutions. Call your local Bose® Support contact for assistance with unlisted or unsolvable faults.
· Unplug/replug USB connector. · Uninstall ControlSpace Designer software, download the latest version, reinstall. · Restart PC, try again. · Try another USB port on the computer. · Try another USB cable. · Check ControlSpace Designer software documentation for more details.
· Check the IP address of the PowerMatch® amplifier. · Ensure that there is not another device with the same address on the network. · Ensure ControlSpace Designer is connected to the same subnet as the PowerMatch amplifier. · Try another shielded CAT5e cable. · Launch a Windows Command prompt window (cmd.exe) and enter the text “ping” followed by the IP address of the
amplifier at the command prompt then press enter key. This should result in four successful replies from the amplifier.
