Connecting the ASR Basis Exclusive

2.1

Connecting to a preamp or an integrated amplifier

ATTENTION: Before connecting cables to the inputs or outputs please switch the main unit OFF.
U U
After you made this connections you may connect the power cord to the AC outlet as last cable.
On the back panel of the main unit the output sockets ( named with „Out") are located left and right
of the power supply cable. The input sockets are located left and right of the „Out" sockets and are
named with „In". The RCA sockets for the right channel are marked with a red ring, for the left
channel with a white ring.
The ASR Basis Exclusive has two outputs RCA for unbalanced and XLR for balanced connection.
You can use them both also together upon your needs.
When you are using the balanced inputs you are not obliged to use the balanced out.
The preferred output is the unbalanced type, cause the balanced signal is made with a converter.
2.2

Connecting the tone arm cable

BCC
Moving Coil (MC) and MM cartridges can be connected to the ASR Basis Exclusive.
Balanced or unbalanced connection can be used at the inputs of the Basis Exclusive !
But we strongly recommend the use of balanced connection !
The ASR Basis Exclusive is designed for using the balanced input and has best results only with
balanced input connection.
!! Cartridges are like microphones the only balanced sources from their construction !!.
With unbalanced connection at the input you don't have the full possible sound quality.
The use of the balanced output is not obligatory together with the use of the balanced input.
Definition of a Balanced connection :
A balanced tone arm cable must have two conductors and a separate shielding.
This shielding has to connected separately to ground and should never be connected to the plus or
Minus wires- otherwise you will get heavy distortions, cause the shield will work as antenna !
Balanced cables can be connected at both the RCA or the XLR plug. Both inputs sockets are
internally connected. The RCA inner pin is connected to Plus, the outer ring to Minus.
The pins on the XLR sockets are international standard: 1 = Ground, 2 = Plus 3 = Minus.
The only advantage of using XLR is that the third pin 1 can be used for ground connection of the
shield. At RCA the shield must be connected separately to the big ground pole plug connector.
A tone arm cable that has already two wires and be converted simply by connecting the shield to
ground ( the black pole plug at the Basis ) instead of to the outer ring at RCA what is minus.
At balanced connections the adjustments have to be made at both 12 Pin Dip switches left
and right. The switch Dip No. 12 has to be OFF.
Please connect the ground cable of your turntable to the (black) pole terminal on the back panel.
