All connection terminals are located on the rear panel. While connecting the preamp, all components of the music
system must be turned off.
Through factory settings a lot of functions are disabled to operate the 100 as a simple Phono preamp.
Analog Inputs
The balanced inputs INPUT 1 (34) and INPUT 2 (31) of the 100 are to be connected to
pickups of either Moving Magnet (MM) or Moving Coil (MC) systems. Which input supports
MM or MC can be seen on the rear panel of the 100.
PLEASE NOTICE: Do not connect a regular high level output (e.g. CD-Player) to these
inputs. Severe damage to your equipment or to your ears may be the result.
The pinning of the balanced inputs is: PIN1=GND, PIN2=NEG, PIN3=POS.
Adapter Plugs
If your pickup components should only offer unbalanced outputs, you are able to use our
balanced inputs with the adapter plugs as unbalanced inputs. In these adapter plugs the pin
2 (negative input) and pin 1 (ground pin) are connected (see graphic below). For each
equipped input 2 XLR-RCA adapters plugs are delivered with the unit, allowing you to use
both inputs as unbalanced inputs. If you need further plugs for other units you may get them
at your authorized dealer.
NOTICE: Please use BURMESTER XLR-RCA adapters only.
GROUNDING Screw
The GND screws (32) and (33) serve for the unbalanced connection between your record
player and the preamp. To link the ground cable loose the GND screw, clamp the GND wire
of your record player between the two washers and tighten the GND screw until the GND
wire can not slip out.
Don't use any other tools but your hand to tighten the GND screw! This way you avoid
over winding the screw.
Analog Output
The 100 offers two analog outputs. The BALANCED OUTPUT (30) and the UNBALANCED
OUTPUT (29) are designed to be connected to a preamp or integrated amplifier. These
outputs supply the analog signal of the selected input.
PLEASE NOTICE: Do not connect the Phono preamp 100 directly to a power amp or active
loudspeakers when the preamp is in factory settings. Severe damage to your equipment or
to your ears may be the result. To operate the 100 directly with a power amp or active
loudspeakers you have to activate the variable volume control. You'll find instructions on
how to activate that option in chapter OPERATING CONTROLS (page 8).
The pinning of the balanced analog output is: PIN1=GND, PIN2=NEG, PIN3=POS. (when
the PHASE REVERSAL switch (40) is set to 0°)
The pinning of the balanced analog output is: PIN1=GND, PIN2=POS, PIN3=NEG. (when
the PHASE REVERSAL switch (40) is set to 180°)
