AUDIO GROUND Selection
Ground hum can be a chronic problem on any system using non-Tenor equipment.
Generally ground hum is caused by stray voltages being injected into the grounding
system by equipment not insulated properly and those stray voltages work their way
through other equipment to get to a proper ground and as as result get amplified in
the signal path.
The Tenor Phono 1 offers 3 settings for grounding to assist in alleviating ground prob-
lems. NORMAL is the audio circuit grounded through a resistor to convert stray volt-
ages into heat and is the best alternative. GROUNDED is direct to ground and LIFTED
is isolated from ground. Should ground hum exist from other equipment, try all 3 op-
tions to determine the least amount of hum. Should additional action be required, go
to the preamplifier and amplifier to try grounding options available with each. The
Tenor Line 1/Power 1 and all models of Tenor amplifiers have several similar grounding
options available to isolate this problem.
Under SETUP and using INPUT up and down buttons, choose the audio ground option
that provides the least amount of ground hum.
