4.1 Independent (8x) rotary preamplifier gain controls

pre@a3p/i.ier /e4e/. 60dJ o. 4ariab/e gain is a4ai/ab/e per c*anne/. C/ock?ise rota@
tion increases t*e gain1 ?*ereas anti@c/ock?ise rotation decreases t*e gain.
! Always begin using the EP84 with all gain controls set to the minimum value.
This way you can increase each channel gain gradually to the desired level with-
out experiencing possible unwanted and unexpected loud signal surprises to both
you and the rest of your audio equipment!
4.2 Independent (8x) -20dB PAD switches

! This function is useful when connecting extremely "hot" signals. Excessive signal input levels can
overdrive the EP84’s pre-amplifier input stage resulting in unwanted signal distortion. The PAD
switch allows -20dB of gain attenuation/reduction to compensate for this situation prior to finer pre-
amplifier gain adjustment.
