Connecting Audio Source Units
The USP-1 can connect to up to seven different audio devices, using standard RCA analog connectors.
PHONO
Connects to a turntable using standard RCA type connectors. Connect the Left output on the turntable
to the Left input of the PHONO INPUT section on the USP-1, and the Right output to the Right input of
the PHONO INPUT section of the USP-1.
Also note the connection of the chassis ground tab between the turntable and preamplifier. This is
necessary for audio signal reference so the USP-1 processes signal from the turntable with minimal
unwanted noise.
Select the type of cartridge, either high output Moving Magnet (MM) or low output Moving Coil (MC) by
moving the switch to the appropriate positions.
If you are not sure which type of cartridge you have, select MM first and then if the noise level is too high,
try selecting MC instead.
The PHONO input is not designed for line level sources such as CD players or other devices.
Please ONLY connect turntables with Moving Magnet or Moving Coil needle cartridges to this
input to avoid damage.
If you are using a separate preamplifier for your turntable, do not use the USP-1 Phono input
section. Use either the AUX1 or AUX2 inputs. The USP-1 Phono input is a high gain input, and
turntable preamplifiers have high gain output. Combining the two would result in an extremely
high gain signal that would cause unwanted distortion.
CD
Connects to a CD Player using standard RCA type connectors. Connect the Left output on the CD player
to the Left input of the CD INPUT section of the USP-1, and the Right output on the CD player to the
Right input of the CD INPUT section of the USP-1.
* This is not a dedicated input, and can be used as an input for a device other than a CD player.
TUNER
Connects to a Tuner using standard RCA type connectors. Connect the Left output on the Tuner to the
Left input of the TUNER section of the USP-1, and the Right output on the Tuner to the Right input of the
TUNER section of the USP-1.
* This is not a dedicated input, and can be used as an input for a device other than a Tuner.
AUX1 & AUX 2
These inputs can be used with most 2 channel audio source devices, including DVD players,
personal computers, portable media players, MP3 players/docks, etc.
Depending on the type of
media player and/or docking station available, direct RCA outputs may not be available, so a 1/8” stereo
mini jack to RCA adapter may be necessary to complete the connection. Analog outputs on the audio
devices are necessary to connect to the USP-1
