Chordette PRIME User manual

Thank you for purchasing the Chordette Prime. In order to get the most from your product
please take a few moments to read these instructions.
Connections
There are four pairs of identical analogue inputs with RCA phono type connectors. These
can be used to connect to line level output source equipment such as the Chordette Gem
or a CD player. The USB input is bi-directional and can be used for both playback and
recording to and from a personal computer. Connect to a spare USB port on the
computer using the provided A-B USB cable. The optical TOSLink output is provided as
a digital monitor for connection to an external DAC when the USB recording output is
being used.
There is a smaller connector under the USB that is used to carry control signals to other
Chordette products such as the Gem Mk II. Refer to the individual product for manual for
more details.

Balance Control
On the side of the unit is a small hole for the balance con-
trol. Using a small flat bladed screwdriver the output bal-
ance can be adjusted left or right.
Using the Prime
Plug the Prime into the wall adapter provided then connect
this to the wall socket. The display will illuminate and show
the selected input.
Select the input source:-
Press the INPUT button on the front panel to select the input
source.
The options are shown in the diagram below:
Adjusting the volume
Use the volume buttons to adjust the volume manually. The
volume range runs from 0 to 98 and is displayed on the
Prime display as you change the volume. If the outputs are
muted, a volume change will un-mute the outputs to prevent
large changes in volume from damaging your loudspeak-
ers. The volume level is shown on the display as the word
VOL and a two digit level as shown in the example dia-
gram below.
Volume display
To reset the microprocessor press and hold the set button until the display reads reset
then press the input button to select an input.
Using USB playback and digital audio recording
Connect your personal computer via an A to B type USB cable. The Prime will automati-
cally be recognised by the computer as a USB microphone or recording device and
also a USB DAC. You may need to select the USB connection in the sound settings on
the computer.
Most operating systems include sound recorder software that can be used to archive
music whilst it is playing via the Chordette Prime. For professional results there are many
commercial software packages available, please choose the one that best suits your
needs.
Optical digital output
Once a recording has been made and providing the USB cable is still connected to the
personal computer you can play back the recording via the optical digital output into an
external DAC or digital input on a Hi Fi system. Simply connect an optical cable then
play the archived content via any media player on the personal computer. The output
will be 44.1 or 48KHz PCM digital audio format.
Muting
Press the SET button
to mute the output.

Remote Control
The Prime is supplied with
a system remote control.
Press the HIFI key to begin controlling
the Prime.
Selecting the input source
For convenience you can directly access
the 5 inputs using the buttons at the bottom
of the remote control.
Adjusting the volume
Press the Vol+ button on the centre control to increase the volume, press the Vol- button
on the centre control to decrease the volume.
Mute
Press the mute key to mute the Prime.
To un-mute
Press the mute key again, or select an output, or change the volume.
Chordette Control Signal
Underneath the USB input is the smaller control signal connector. This allows direct con-
trol of the Peach using the Prime and the remote control.
Plug in the cable supplied with the Peach to both products
and set the Peach input selector to the cable connect posi-
tion. Connect the analogue output from the Peach to one of
the inputs on the Prime, for instance Line 1. Using the right
hand set of input buttons (Bus B) on the remote control you
can now select each of the inputs on the Peach.
TP-01 selects Bluetooth, TP-02 selects USB, TP-03 selects op-
tical and TP-04 selects coax.
