2 Rev 1 The Muse® User Manual
Welcome to the family of PS Engineering, Inc. aircraft audio products. We
hope that your new The Muse® will exceed your expectations in craftsman-
ship and audio fidelity.
Description
The Muse® was designed as a personal music device, allowing the incorpo-
ration of entertainment into an aviation headset. Through the use of state of
the art surface mount technology, the size of The Muse® was kept to an
absolute minimum. This keeps the cockpit as clutter free as possible. Addi-
tionally, all wires are permanently connected, preventing lost cables. Eve-
rything you need to hook up your entertainment device is integral to The
Muse™, so you’ll always be ready to ‘Listen to the Muse!’
The Muse® has two powerful output amplifiers that will easily drive gen-
eral aviation headsets. You’ll have plenty of output audio power even when
using the low level output signal that comes from the ‘Remote’ output from
most personal entertainment devices. There is even enough audio punch to
drive two headsets at the same time! (a Y-adapter is required).
Battery Installation
When you receive The Muse® a 9-volt battery (not supplied) must be in-
stalled before use. Slide the battery cover off, connect the battery to the
battery clip, and slide the battery in as shown.
Operation
The Muse® was designed to be very easy to use. With only one switch, and
no power on/off switch, it is virtually impossible to miss configure it.
Below is the configuration diagram showing interconnection for your gen-
eral aviation headset and an entertainment device.

stereo or monaural music. Whenever the aircraft radio becomes active (or
intercom is in use), The Muse® will instantly mute the music to a back-
ground level. When the activity ceases, the music level is gradually brought
back to full level so as not to be startling. This feature is known as “Soft
Mute”. This switch on the unit allows you to inhibit “Soft Mute” mode,
permitting you to play music at a constant background level.
This mode of the “Soft Mute” circuit is sometime referred to as the Sing-
A-Long or karaoke mode.
The Muse® is always on, and monitoring the music input line that comes
from the
entertain-
ment device. When the en-
tertainment device is not
playing, the unit is in the
“sleep mode”. This “sleep”
mode requires an incredibly
small amount of current
(l7µA). The instant that The
Muse® detects a signal on
the music input line, it turns
itself on. When the signal
goes away, it turns itself back into the “sleep” mode. This is completely
automatic, you’ll never have to turn the unit off, or unplug any cables.
The Entertainment Device
The Muse® was designed to work with portable
Compact Disc or Cassette players. Connect the
cable that has the 1/8” stereo connector to the
“headset out” of the device. This output usually
has a volume control associated with it so that
you will have the ability to adjust the music lis-
tening level. You may use the “remote out,” how-
ever; the performance of The Muse may not be
optimized.
Battery Replacement
Once the 9-Volt battery has been exhausted, it is easy to replace with a new
one. Slide the back panel in the direction indicated by the arrow. Remove
the battery and install the new one. Replace the battery cover, being certain
to slide it in its track. This completes the battery replacement.
