4 Azur phono pre-amplifier
MC input sockets (640P only)
If your turntable uses a moving coil cartridge, connect outputs here
(0.5-1mV, with 100 ohm 220pF loading).
MM input sockets
If your turntable uses a moving magnet cartridge, connect outputs here
(3-5mV, with 47k ohm 220pF loading).
Turntable ground
If your turntable has a separate grounding lead then connect here. This
provides shielding to the arm and the sensitive circuitry in the turntable.
Cartridge Type selector switch (640P only)
Match this switch to the cartridge type that your tunrtable uses. MM for
a moving magnet cartridge or MC for a moving coil cartridge.
Subsonic Filter (640P only)
The subsonic filter cuts out very low frequency ‘rumble’, caused by vinyl
imperfections, which can affect your system’s performance.
Output sockets
Use phono cables to connect to any line level input on your amplifier,
such as Aux.
NB. Do not connect to a phono level input.
PSU socket
Once you have completed all connections to the amplifier and turntable,
plug the PSU power cable into an appropriate mains socket. The blue
LED on the front panel will indicate that the power is on. The unit has
been designed to be left permanently powered.
Please note the 640P has an output relay, which after power on takes
15 seconds to come out of mute.
NB. Only use supplied power supply.
