7.2.4.1
Input Configuration
Purpose:
The Input configuration block configures an input’s
display property, pre-gain level, and phantom power (if
available). This processing block should configured first as
adjusting pre-gain levels will have a dramatic effect on
subsequent processing blocks further down the signal path.
Display Name
is an editable textbox that accepts all
alphanumeric characters as well as a limited number of special
characters. The display name will appear on the input label as
well as in the mixer matrix.
Input Type
is a dropdown menu populated with hardware-specific pre-gain levels. These pre-gain levels
include an input device type as well as gain level in decibels (dB). There are 3 gain options: 0 dB (line level),
+6 dB (intended for consumer grade signals), and +20 dB (intended for lower level microphone inputs).
Note that this is mathematical gain. There are no preamplifiers in FLX-E Series amplifiers. All processing
blocks have 24dB of headroom so selecting a pre-gain higher than 0dB will adjust the upper limit of the first
gain block to compensate for this loss of headroom.
Phantom Power
is a checkbox that is visible for inputs 1 and 2 only.
Note
– this checkbox will be
automatically un-checked if a Line Level pre-gain is selected to prevent harm to devices that do not support
phantom power. It will display a warning if phantom power is selected after it has been unchecked.
Signal Meter
displays the current RMS level in dBV of the audio signal including both pre-gain and input
pre-amplification (applied in input type).
7.2.4.2
Gain Block
The Gain block configures and monitors the gain level at various places along the
processing signal path. Bear in mind that the signal processing blocks have 24 dB
headroom, so excessive gain may result in signal clipping.
Gain
is adjusted using the fader control similar to the interface on an analog mixing
console. When moved up and down the textbox below the fader control will update
to reflect the current gain setting. The gain slider is disabled when the block is
muted.
Mute
is an on/off button that will turn red when active. The gain fader will be
disabled and >100dB of attenuation will be applied to the signal. A red indicator will
appear on the gain block button in the main Device Screen when that block is
muted.
Signal Meter
displays the current RMS signal level in dBV of the audio signal at the
output of the gain block.
