• Coaxial Digital Input: Connect the coaxial output from any digital source, using
a coaxial digital cable. Push the “COAX” input button on the front panel of the
musicBox to listen to your connected source component.
• Optical Digital Input (sometimes called Toslink): Connect the optical output
from any digital source, using an optical digital cable. Push the “OPT” input button
on the front panel of the musicBox to listen to your connected source component.
• USB Digital Input: Connect the USB output from a computer (or other source
component which can output audio via USB) using a USB cable. Push the “USB”
input button on the front panel of the musicBox to listen.
• Aux Input: Connect the left and right channel outputs from a tuner, tape deck or other analog source component.
Push the “AUX” input button on the front panel of the musicBox to listen to your connected source component. You
can connect a turntable to the aux input of the musicBox if you wish; however, you’ll need to send the left and
right channel signals from your turntable to an external phono preamplifier first. You can then connect the outputs of
the phono preamplifier to the left and right aux inputs of the musicBox. (Some turntables have a phono preamplifier
built in and can be connected directly to the musicBox aux inputs.) We recommend you consult your dealer for
recommendations on properly hooking up your turntable to the musicBox.
• Component Video Out: This allows a high-resolution pass-through of a video signal from your iPod (when
connected to the iPod dock on the musicBox). Using a set of component video cables, connect to the component
video inputs of a television, A/V receiver or A/V preamp/processor. Video quality will be dependent upon the quality of
the video program stored on your iPod.
• Speaker Output: Connect your speakers to the left and right speaker terminals of the musicBox using high quality
speaker wire. Be sure to observe correct polarity when you make your connections. Connect the “+” terminal on each
speaker to the corresponding “+” terminal on the musicBox; likewise for the “-” terminals. Also, be sure not to let stray
strands of speaker wire from one terminal touch another terminal or another wire. The musicBox is designed to drive
one pair of speakers with a rated output impedance of between 4 and 8 ohms. It is not advisable to use more than one
pair of speakers with the musicBox.
• Bass EQ: Push in the “Bass EQ” button to engage the bass boost function of the musicBox. This boost has been
designed to complement the bass roll-off characteristics of the matching Peachtree Audio mB3 speakers, but should
work well with most small bookshelf speakers. (Depending upon your speakers and their placement in the room, your
music, and your personal listening tastes you may prefer the sound of your system either with or without the Bass EQ
function engaged. There is no “right or wrong” here - let your ears be your guide!) The “Bass EQ” button should be left
out (not pushed in) when using the musicBox with larger full-range speakers or with a subwoofer.
• Pre Out: The stereo preamplifier output jacks provide flexibility in maximizing the performance of your musicBox-
based audio system.
External Amplifier
The musicBox does not limit you to using its internal amplifier to drive your speakers. If you wish, you may connect a
more powerful external amplifier to drive your speakers - provided your speakers can handle the extra power, of course!
(If you have a question regarding suitability of a particular amplifier for your speakers please consult your dealer.) Be
sure the musicBox and the external amplifier are both turned off. Connect a stereo RCA cable from the musicBox “Pre
Out” jacks to the stereo RCA inputs of the external amplifier; connect your speaker wires to the speaker terminals of the
external amplifier. To listen to music turn on the musicBox first, then the external amplifier; reverse this sequence when
turning the system off. You are now using the musicBox as a high quality digital and analog preamplifier, controlling a
music system limited in power only by your budget and your ears!
Subwoofer Output
(There are several different ways to connect a subwoofer in a music system. Refer to your speaker and subwoofer
manuals for instructions for your particular system.) If you are using a subwoofer that requires (or accepts) a “line in”
connection from your amplifier, connect a stereo RCA cable from the musicBox “Pre Out” jacks to the subwoofer stereo
input jacks. If your subwoofer has only one “line in” jack, you may use a single RCA cable from either the left or right
musicBox “Pre Out” jacks. Even with this single-cable hook up you will lose little or no musical information, since most
recordings mix bass frequencies in mono.
