Channel Strip.
High Pass Filter - Microphone Preamplifier option only
A 75 Hz HPF with a 12 dB per octave roll-off rate can be
engaged on the mic/line source - useful for removing low
frequency content that clutters up your mix and robs the
console of headroom.
Considering that many listeners use systems that can barely
reproduce 60-70 Hz accurately - a well placed HPF on certain
sources can clean up mix elements that contain sub-sonic
energy, such as microphone stand rumble, traffic noise, or some
plosive material etc.
48v Phantom Power
Engaging this switch provides 48 volt d.c phantom power to the
microphone input. Phantom power is applied via a pair of
current limiting resistors to XLR pin 2 (hot +ve) and XLR pin 3
(cold -ve). Zen phantom power is within the DIN 45956
specification of 48v, +/-4v @ 10mA per channel.
With individual phantom power switches on each channel - you
have total control over which microphones receive power and
rest assured that the powerful switch-mode power supply can
deliver all the current needed for the most hungry of microhones.
