HIGH PASS FILTER
There are two high-pass filter switches on the Decoder for input-1 and
2a/b. High pass filters are extremely valuable when recording as they
eliminate excessive low frequency rumble and can do wonders at
cleaning up a mix. Simply depress the HPF to audition. Note that both 2a
and 2b share the same HPF switch.

48V PHANTOM
The Decoder is equipped with 48V phantom to remotely power condenser
microphones and active direct boxes. There are two switches, one for
input-1 and the other is combined for inputs-2a and 2b. These switches
are recessed to prevent accidental use. Make sure you turn levels down
or audio systems off before activating phantom power as the turn on
transients can create a loud pop that could damage components such as
tweeters. Although phantom power will not harm dynamic microphones or
passive direct boxes, some older ribbon microphones can be damaged if
DC current is applied. Please check with the manufacturer to ensure the
use of phantom power is safe. As a precaution, always turn off phantom
power when using ribbon mics
POLARITY REVERSE SWITCH
The Decoder is equipped with a 180° polarity reverse that is primarily
used to replicate the sound of a figure-8 microphone when using two
separate cardioid mics.
You can also use the polarity reverse when using the Decoder as a mic
preamp by using the input-2b GAIN control and 180° switch to change
the relative phase. This can be particularly useful when combining a near
and far mic to create a more solid rendering.
