Bettermaker EQ 502P - Manual (Page 9)

Presets
On the lower right corner is the PRESET section (pictured below), which saves and recalls the entire state of the
unit. The multi-purpose knob can rotate as a digital encoder and be pressed as a menu selector button in tandem
with the 3-digit LED Read-out. Operation is described in detail below in Part V, Software .
Stereo / Dual Mono
Over the preset section is a stereo/dual mono selector button (pictured above). This unlinks the channels of
the EQ502P to allow dual mono processing. For example, during tracking, one channel could equalize the main
vocal, and the other the bass. In mastering, one channel could have a different eq than the other (with caution to
avoid phase and image shift if making extreme changes). Or, an external M/S converter may be used to separately
equalize the M and S channels during mastering.
Currently the CH button cycles through three states. A long press (about 1 second) switches between LINK
(stereo) and UNLINKED (dual mono) mode. A short press switches channels when in UNLINKED mode. For
example:
1) Unit is in stereo operation and LINK is illuminated.
2) Press CH to switch the unit to dual mono; the indicator now displays 1 showing you are in control
of channel 1. The state of channel 1 is remembered from the last time the dual mono state was used, so no
information will be lost when switching back and forth between Linked and Dual Mono states. When unlinking,
both channels receive the same setting (setting of channel 1). So If you use the dual mono mode, be aware that
linking it back will copy channel 1 setting to channel 2.
3) Press CH (a short brief touch) and the indicator displays 2 showing you are in control of channel 2. You can
alternate between controlling channel 1 or 2 by a simple short press of the CH button.
4) Press and hold CH (for about 1 second) and the equalizer returns to LINK mode.
It is possible to transfer or copy settings from channel to channel using the Presets (See Part V ).
