BYPASS:
The bypass function is located just above the low cut filter, and is engaged with a
toggle switch which activates an electronic relay. When “IN” is selected, the EQ is
active. When “OUT” is selected the XLR input jack is routed directly to the XLR
output jack for a direct hard bypass, and the EQ circuit is removed from the audio
path completely. It’s not unusual to hear a click or pop when engaging or
disengaging the bypass function. This is particularly true if audio is running
through the unit, as the waveform is essentially being chopped by the relay.
A LITTLE EXTRA INFO
There are a few things that are useful know about this Bax EQ, as well as
Baxandall EQ’s in general. The first is that the bands of the EQ are both fluid and
interactive. What that means, is that unlike most EQ’s where the frequency
points on the front panel are static, with a baxandall eq that is not the case. The
actual knee point of the filter curve will move a little bit depending on how much
boost/cut you’re using of that filter band, AND the knee point will also move
depending on how much boost/cut you’re using of the other filter bands. The
more boost/cut you use, the more the knee will shift. The labeled frequency
points on the front panel are a general average of the knee location, but they
should not be taken as a definitive hard number. Baxandalls are intuitive,
emotive eq circuits and should be used as such.
One feature that separates the RJR BAX not just from other baxandall equalizers,
but also from just about every other eq that has fixed frequency selections, is that
it employs a toggle switch bank for frequency selection rather than a standard
knob-based rotary switch. While at first this may seem odd, it actually grants the
user some liberties that would otherwise not be available with a regular rotary
switch.
The first is that it is possible to select more than one frequency setting at a time
for each of the high and low bands. Choosing multiple frequencies at once will
result in a new frequency that is lower than the lowest of the frequencies
selected. There are a ton of different possible combinations, use your ears and
see what’s possible!
The other unique quirk that a switch bank allows is that it is possible to select no
frequency. For the low band, selecting no frequency removes all filtering action
from the low band, resulting in a full range boost/cut control. For the high band,
selecting no frequency disables the high band’s boost/cut control. Each could
potentially be useful for special effect type applications.
Under normal operation, when changing frequency settings, it is useful to simply
flick one setting off with your thumb at the same instant that you flick another
one on with your forefinger. That way you can create a seamless transition from
one frequency to the next.
