PAD:
Engaging the Pad switch provides -20dB of attenuation with the push of a
button. This is a very useful feature for rapidly reducing the level coming into the
EUREKA and thus preventing the input signal from over-driving (distorting) the input.
This may occur due to high output level from a microphone or other device. Padding
the input serves to provide increased “headroom” for the operator while lessening the
likelihood of input signal overload.
80Hz:
The 80Hz button is a low-end roll-off filter. When pushed in, the 80Hz button
causes all frequencies below 80Hz to be attenuated (dropped) by 12dB. This filter can
be handy in live and studio applications. For example, the 80Hz filter can help to
reduce the “boominess” or “muddiness” of a vocal and improve the overall clarity.
Ø (Phase Reverse):
Reverses the polarity of the signal. Use the phase reverse
when recording with more than one open microphone to combat phase cancellation
between microphones.
INSTRUMENT:
¼” TS connector. When an instrument is plugged into the instrument
input, the microphone preamplifier is bypassed and the Eureka becomes an active
instrument preamplifier.
