Analog Audio Input Connections
Always disconnect your P 5's AC cord before making or changing any input, output or trigger wire
connections. Inserting or removing an input or output cable while the P 5 is turned on can result in
a blast of sound that could damage your loudspeakers. Make sure there is no strain or tension on
any cables that could cause them to pull loose.
Phono Input
The P 5 is equipped with a high quality phono preamplifier. If you wish to connect a turntable,
set the Load/Cartridge switch to MM (moving magnet) or MC (100
Ω or 47k Ω moving coil),
depending on your cartridge type. Select MM if you are not sure which type of phono cartridge
you have because MM cartridges are more common. If you use the MC setting with an MM
cartridge the volume level will be very high and distorted. Only a turntable can be connected
to the Phono input.
Phono Load/Cartridge Switch
The Phono input has a 3 position load/cartridge selector switch. Select the switch position that
matches your turntable cartridge type. We recommend that you contact the cartridge
manufacturer if you are unsure which setting is best for your equipment. You may also try all
three settings and use the setting which sounds the best in your system and listening room.
.
MM
is for moving magnet cartridges. It provides a 47k ohm load and the appropriate gain
for all MM cartridges. This is the most common cartridge type.
MC 100
Ω
is for most moving coil cartridges. It provides the higher gain required for even
very low output MC cartridges and a 100 ohm load that is ideal for the majority of MC
cartridges.
MC 47k
Ω
provides the appropriate gain for MC cartridges with an alternative 47k ohm
load. You can try both the 100
Ω and 47k Ω settings to see which sounds best in your
system
.
The MC 47k
Ω setting is also the load Grado recommends for their MI (moving
iron) cartridges.
Note:
If your turntable won’t reach adequate volume, or if it plays too loud, you have
selected the incorrect cartridge type. Don’t forget to connect the ground wire from your
turntable to the Phono GND (ground) terminal on the P 5.
