XM Series Power Amps From Yamaha
February 6, 2000
Yamaha announces the introduction of the XM series
multi-channel power amplifiers at Winter NAMM 2000. Two new models–the
XM4220 and the XM6150–are powerful, cost-effective choices for any
installed or live application with a standard PA or distributed speaker
system.
The XM4220 delivers four channels of 220-watt power (20 Hz to 20 kHz)
into 4 ohms, and two bridged mono channels of 440 watts. The XM6150 offers
six channels of 150-watt power at 4 ohms (20Hz to 20kHz), or three channels
of 300 watts, bridged mono. Total Harmonic Distortion is < 0.2%. The
XM4220 and XM6150 both have an MSRP of $899.95 and are now shipping.
"Anyone who needs multiple channels of clean, high-power amplification
should definitely consider the XM series," notes John Schauer, pro
audio product manager. "Small and mid-sized clubs, houses of worship,
and performing musicians could all benefit from these products. Yamaha’s
amplifier technology is now available for all types of users, for any
application, and it’s very affordable."
The XM4220 and XM6150 are capable of driving both standard and 70.7-volt
distributed speaker systems. Each channel can drive similar or different
speaker types–such as multiple stage monitors or a multi-zone system–from
the same amplifier, while retaining > 60dB signal separation between
channels.
Despite their high power output and compact size (39lb.), the XM4220
and XM6150 are UL-rated, and maintain efficiency, low current draw, and
reduced heat utilizing Yamaha’s EEEngine Technology.
All channels contain a 31-position input attenuator and high-pass filter
for accurate system level matching and signal quality. In addition to
the standard bridged mono selectors, XM series amplifiers feature a parallel
input switch (CH A to ALL CH), which allows all channels to be driven
by the single "A" input source. All controls are rear-mounted
to prevent accidental changes.
Both units are 3RU designs and feature front-panel power controls and
level indicators. Each channel contains both professional balanced XLR
and Euro-block input connectors. Output connectors are 5-pole binding-post.
