Getting started
What’s in the box?
• PH 30.3 Phono Pre-Stage
• Power supply unit
• Load resistor plugs (100Ω, 200Ω, 1000Ω)
CAUTION: After unpacking, please check the scope of delivery to ensure that all the parts have been
supplied and are undamaged. In case the original packing has already been opened, please contact your
local dealer. Often, your dealer prepares your new device prior to delivery to adapt and change the
configuration to your personal needs.
Control and operating elements
1. Ground connection
2. MM input sockets (from turntable)
3. MC input sockets (from turntable)
4. MC cartridge loading sockets
Connect your turntable with the ground connection „GND“ (1) and one of the available input sockets
“MM” (2) or “MC” (3). Depending on the operating principle of your cartridge, please choose one of the
available phono inputs for electromagnetic transducers (MM = Moving Magnet) (2) or electrodynamic
transducers (MC = Moving Coil) (3). Please refer to the manual of your cartridge system to find out on
which principle it is based. Depending on the desired load resistor of your MC system, your MC system
may solely be connected with the MC input sockets (3) or additionally be adapted via the MC cartridge
loading sockets (4) and the supplied load resistor plugs (100Ω, 200Ω, 1000Ω).
5. MM / MC selector switch
6. Output sockets (to amplifier)
7. Power switch
8. Power socket (from power adaptor)
