3. Controls and Connections
Note: 24V power supply
The included 24VDC power supply is a certified wide-range
model, capable of handling input voltages between 100V
and 240V. A substantial amount of research, effort and tes-
ting went into the selection of this power supply. It is critical
to the function of the preamp – please use no other power
supply!
Also please bear in mind that any device powered from a po-
wer supply (as opposed to battery opera-tion), may suffer in-
terference carried by the electricity supply itself. To avoid this,
always try and keep signal cables as short as possible.
We have opted for a “non-earthed power supply“ (class 2 with
protective insulation) in order to avoid unwanted earth or
ground loops that occur when using seve-ral earthed mains
powered devices in a signal chain.
4. Operation Summary
4.1 Cabling and Starting-up
Before connecting to the mains, please ensure that your lo-
cal mains voltage (e.g. 230V in mainland Europe, 120V in the
USA) is suitable for the voltage input range of the included
power supply. The relevant specs and safety symbols are
printed on the rear side of the unit.
Please ensure that
gain
- and
level
-controls are in their midd-
le position (centre detent) and all other controls are turned
all the way to left. The pushbuttons should be off, i.e. not pu-
shed.
Make all signal cable connections as desired (e.g. output of
upstream device to
input, line out to input of downstream
device). Now you can connect the unit to the power supply.
The green
power control LED indicates operational readiness.
