5 HI
If you turn this control up, you will boost all the
frequencies above 12 kHz (shelving filter). You
will add transparency to vocals and guitar and
also make cymbals crispier. Turn the control
down to cut all frequencies above 12 KHz. In
such way, you can reduce sibilances of human
voice or reduce the hiss of a Tape player.
6 LOW
If you turn this control up, you will boost all
frequencies below 80 Hz. You will give more
punch to bass drums and bass guitar; and
you will make the male vocalist more "macho".
Turn it down and you will cut all the frequencies
below 80 Hz. In this way, you can avoid
low-frequency vibrations and resonance thus
preserving the life of your woofers.
7 TAPE IN
Your PBM4 features dual RCA jacks (left and right). If you wish to listen to
your monitor from a tape recorder, DAT or cassette, please use these tape
input jacks. You can connect the outputs of a CD Player, MP3 Player, iPOD or
another line-level stereo source to these RCA sockets and adjust the level
control. It is a very useful extra stereo channel.
8 TAPE OUT
Via these jacks, you can route the main out signal into a tape recorder or DAT
to record your event.
9 LEVEL
This knob will control the level of the signal applied to TAPE IN RCA input.
10 MONITOR
This knob will control the level of the signal sent to the monitor output
11 GRAPHIC EQ
Your PBM4 is equipped with a 7-bands graphic equalizer. Via these faders, you
can boost or attenuate the selected frequency by 15dB at a preset bandwidth.
When all faders are on center position, the signal will be unaffected.
