Excessive hum and/or noise
Vinyl record playback is never as quiet and noise-free as high-quality digital sources such as
CDs, but noise or hum should not intrude to the point where it distracts you. If your system
is producing too much noise or hum, try the following steps in order. If one step eliminates or
adequately reduces the hum or noise, you can ignore the other steps.
1.
Check the ground connection between the turntable or tonearm and the phonostage.
If it has become loose, reconnect it.
2.
If the ground connection is not loose but you're still hearing hum, try disconnecting the
ground. If this does not reduce the hum, reconnect the ground wire.
3.
If you are using an MM cartridge, try increasing the load capacitance on the
phonostage. If this does not fix the problem, adjust the load capacitance back to the
original setting.
4.
Switch to a digital source device such as a CD player or DAC. If this stops the hum or
noise, you may have a bad connection between the turntable or tonearm and the
phonostage, or between the phonostage and the preamp or integrated amp. Check
these connections. If you need to reconnect anything or replace a damaged cable,
first turn off your preamp or integrated amp. Fix the connection, then turn the system
back on.
5.
If you still hear the hum or noise when you switch to a digital source device, the
problem is elsewhere in your system. If you're using separates, make sure the
connection between your preamp and amp is secure and that the interconnect
cables are not damaged.
6.
If none of these steps eliminates most or all of the hum or noise, please contact your
dealer for assistance.
