CM
™
Series power amplifiers feature a unique amplification architecture
providing a host of user benefits including simplified operation and use in
multiple applications, as well as unsurpassed sonic quality and flexible power.
The CM 2204-AB (US model)/CM 2204-DV (European model) and CM
2208-AB (US model)/CM 2208-DV (European model) are easy to set up and
operate. Housed in a lightweight-but-rugged 16-gauge steel chassis, multi-
load architecture allows low impedance or 70 Volt operation without so
much as flipping a switch. Each channel outputs 220 Watts (70V or 8 Ohms,
or 160 Watts into 4 Ohms) for flexible system configuration, while front-to-
side cooling delivers low mains current draw, ensuring efficient operation in
a 2U rack space.
CM Series products comprise four-channel (CM 2204-AB/DV) and eight-
channel (CM 2208-AB/DV) units (channels are independent). A host of
applications benefit from the use of multiple channel amplification, including
bars, clubs and restaurants; video conferencing systems; hotels and motels;
industrial installations; and retail stores, among others. One amplifier
for multiple applications provides a cost-effective solution, expansion
opportunities and unparalleled flexibility.
The CM Series has numerous circuit protection features, including:
Automatically reduces gain at the onset of clipping to prevent amplifier and
load damage.
Monitors load current to protect against overloading.
Gradually increases gain when the amplifier is turned on, preventing abrupt
turn-on level.
Short circuit, DC voltage, comprehensive thermal management, current in-
rush turn-on/off transient and sub/ultrasonic input.
Some of the protection features are described in more detail later in this
manual but please note that improper use can be dangerous to the user as
well as the unit. These amplifiers are very high-powered and can produce
high voltages and sizable currents. Always use safe operating techniques
when operating these amplifiers but we also encourage you to read this
manual thoroughly.
