Mounting :Mounting :
Connect terminal according to wiring scheme.

Backside view
Terminal no
1 + Signal – out ( unbalanced )
2 0 Signal
3 Reduced gain
4 + Control input 0-12 VDC
5 0 V Control
6 0 Supply voltage
7 + 24V Supply voltage
8 0 V Phantom / Mic
9 + Mic input
10 + 24V Phantom
Note : The control terminal no. 4 gets a voltage of 12V by an internal resistor. So the preamplifier
has the maximum gain at open terminal.
If the gain is too high for some applications , connect the accessory wire bridge to terminal 3 and 5.
This will reduce the gain to app. 1/3.
Note : Teminal 8 to 10 is only for use with input balance unit.
For the signal and control line we recommend shielded cable.
LIYCY 0.14mm² 2-cores
e.g.
The cross section of the power supply cable should be adequate.
H03VV-F 0,5mm² 2-cores
e.g.
We recommend regulated 24VDC power supply with short circuit protection.
