Art Pro Channel, Руководство пользователя, Страница: 15 / 24

generally referred to as the “air” band. While there aren’t very many instruments that
contain 18KHz information directly, many instruments and mixes contain upper
harmonics, which can add extra definition and space when boosted. Cutting at 18KHz
can decrease hiss and noise.
High Shift Switch
The High Shift switch selects the corner frequency of the High Frequency control. In
the “out” position the corner is 18KHz. In the “in” position the corner is 6KHz.
Note:
The High Frequency and Hi-Mid Frequency controls overlap. This feature gives you
the ultimate in flexibility. For example, on cymbals try boosting 18KHz with the High
control while cutting 20KHz with the Hi-Mid control for a very bright, yet noise-free
result.
EQ Bypass Switch
A Bypass switch is included in the equalizer circuit to enable you to remove it from the
signal chain. When set to its “in” (Bypass) position, signal is allowed to pass from the
compressor circuitry to the output tube section with no equalization. The LED will
glow red when Bypass is engaged. In its “out” (Norm) position, the equalizer is active.
Use the EQ Bypass switch to compare your equalized and un-equalized sound – a
reality check to make sure you
are making an improvement! It may be necessary to
adjust the Master Output control to balance the apparent level of the EQ’d and un-EQ’d
signal.
Master Controls
Master Output Level Control
The Master Output control sets the final output level leaving the Pro Channel. When
the control is fully counterclockwise, there is no output. Turning the control clockwise
increases the level of the output to a maximum of +10dB of gain. When setting the
Output Level control, refer to the VU Meter (set for the “Output” option) or the level
meter on your recorder or mixer.
