Introduction
Thank you for choosing Bose® PowerMatch® configurable professional power amplifiers.
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® Designer™ 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.
•PowerMatch Class-D Amplifier
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.
•QuadBridge™ 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.
•PeakBank™ 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® Designer™ 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® Designer™ software.

RoomMatch loudspeakers connect and configure easily to PM8500 and PM4500 amplifiers. Built-in loudspeaker and array EQs together with suitable output power ratings 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.

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.

Making Connections
Connection and Configuration Steps
Use the following procedure when setting up a PowerMatch® amplifier for the first time.
1.Install any digital expansion cards (optional)
2.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 30.)
6.Configure amplifier (use front panel or ControlSpace® Designer™ 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 31.)
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.
