Meyer Sound PSW-4 User Manual

current turn-on, and surge
suppression. Simply apply a
signal source and a power
connection, and the unit is
fully operational.
The amplifier unit
is equipped with TruPower
™
Limiter technology, which
maximizes speaker protection
reliability and component life.
This breakthrough in speaker
control also results in higher
SPL at all frequencies, and
increased available headroom.
Long term power compression,
typically 3-6 dB in conventional
systems, is less than 1 dB.
Maximum SPL capability
remains constant even during
operation at high levels for
extended periods.
The PSW-4 is a self-powered,
dual-tuned subwoofer that
incorporates one 15" and one
18" driver, to give a frequency
response of 32 Hz to 160 Hz.
Being self-powered, all of the
amplifier and controller
electronics are contained
within the speaker enclosure.
The unit is an effective
companion to the MTS-4
(whenever additional low
frequency power is needed),
but can be used in any
situation where a high-energy,
easy-to-use, true-sounding
subwoofer is needed.
The PSW-4 incorporates the
Intelligent AC
™
system, which
performs automatic voltage
selection, EMI filtering, soft
FEATURES
PSW-4 performance can be
supervised using the Remote
Monitoring System
™
(RMS).
This enables users at a
computer terminal to monitor
such parameters as limiting
activity, power output, voltage,
temperature, fan speed,
and driver status.
The cooling, power supply,
and amplifier subsystems
are all built for maximum
efficiency and reliability. In
the event that servicing is
needed, it is aided by the
PSW-4’s modular design; the
entire power/amplifier module
can be accessed and replaced,
if necessary.
