1. When the eq in switch is in the out, non illuminated position, all EQ2231 functions are
bypassed and the input is connected directly to the output with a high quality relay.
This condition also occurs when the power is off, and ensures that the signal is
passed through the unit in the case of a power or fuse failure. When the switch is
pressed, the processed signal is present on the output.
2. Gain control : +10dB to -infinity
3. High Pass filter: from OUT (flat) up to 250Hz./octave.Please see the picture 2 in the
Tech Specification.
4. LF CONTOU control: The smooth shelving filter in the low frequency band can make
fast adjustment for the LF CONTOU. At the frequency point of 50Hz the adjust range
can be
＋
/
－
6dB.And please see the high frequency part of the picture 3 in the Tech
Specification.
5. HF CONTOU control: The smooth shelving filter in the high frequency band can make
fast adjustment for the HF CONTOU. At the frequency point of 14Hz the adjust range
can be
＋
/
－
6dB.And please see the high frequency part of the picture 3 in the Tech
Specification.
6. Output meter: This is a peak reading RMS calibrated meter. Normally when the eq in
buttons are depressed, it measures the signal being sent to the output connector. If
the channel is bypassed (eq in button out), the meter reads the input signal.
7. Overload indicator. It will be on when the signal is overloaded.
8. EQ Frequencyband sliders. Each band may be amplified (boosted) or attenuated
(cut) by up to 15dB while with a constant Q, allowing great control over the program
for either corrective or creative purposes.
