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.
• 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.
• 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 suffi-
cient 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.
