Turntables equipped with a MM (moving
magnet) cartridgesystem must be connected
to the PHONO MM [40] input.
Correct matching of the PHONO input is es-
sential for optimum reproduction of records.
The input capacitance must, therefore, be ad-
justed to the cartridge system with the PF [41]
switch located on the rear panel.
Exception:
When a REVOX B291 turntable is used, always
select the 150 pF setting.
For cartridge systems Elac EMM 150 and
Shure V15V the correct setting is 150 pF. The
setting of other systems can be computed ac-
cording to the example given below. The ca-
pacitance rating can be found in the technical
specifications of the turntable and the phono
cartridge system.
Example:
Nominal capacitance
of phono cartridge: 375 pF
Capacitance of turntable
output (cable capacitance): -225 pF
Correct setting: 160 pF
If the correct value cannot be set exactly, use
the closest possible value. A lower setting
causes accentuation of the (extreme) treble
frequencies, a higher value causes losses in
the (extreme) treble range.
Turntables equipped with a MC (moving coil)
cartridge system should be connected to the
PHONO MC [38] input, butin this case the am-
plifier must be fitted with the optional MC
preamplifier.
When you press the MC [20] key, the MC
preamplifier is switched on and the MM
preamplifier is switched off.
