Gain with VCA
The gain w/ VCA block allows the user to modify a signal's level by either
applying gain or attenuation. The polarity of the signal may also be inverted. The level
control allows for gain adjustment between +12db and -50dB as well as OFF. The level
fader can be adjusted in 0.5 dB increments. Finer adjustment (0.1 dB increments) may
be made by typing in the value into the provided text box below the fader.
Additionally, gain can be assigned to a subgroup using the digital VCA Group.
This allows a single master fader to adjust multiple gains. Note that unlike linking, the
digital VCA group does not change the position of the level fader. Rather, the virtual fader
is created by the digital VCA group. As the digital VCA group master fader is moved, the
amount of gain/attenuation is added to the level shown on the gain w/ VCA fader. This
works similar to a VCA subgroup on a mixing console. Note that a single gain w/ VCA
block can be assigned to up to 4 digital VCA groups, thereby allowing more complex
configurations.
Parameters
Level - Off, -50dB to +12dB in .1dB increments.
Polarity - Normal or inverted.
Digital VCA Group Enabled - Selecting this button enables each corresponding digital VCA group.
Digital VCA Groups - Selecting this will open the VCA groups master faders window.
Total - This indicator shows the total gain/attenuation applied to the channel. It is the sum of the gain of the level fader
plus the gain applied by each of the enabled VCA groups.
RD-8C Remote Control Gain
Remote gain allows the user to choose where Ashly's RD-8C will apply gain to
a signal path (WR5s are handled by the WR5 gain block). When the remote is assigned
to a channel, it applies gain/attenuation within the remote gain block, allowing the other
gain blocks to remain unaffected by the remotes. This allows for more complex setups,
i.e. the system has a specified maximum gain/attenuation (when the remotes are all set
to 0), but may not be the maximum for the unit.
RD8C Controls
The RD8C controls allows the user to see the current status of the RD8C, and
assign faders to a channel. Any fader may be arbitrarily assigned to any DSP channel or
multiple DSP channels. When "Enabled" is checked (green) for a particular RD8C fader,
that fader's attenuation is applied via the remote gain block. The current attenuation for
each fader is also displayed for ease of setup and knowledge of how a fader will affect the
channel. The RD8C active LED is also available. This indicates whether or not a RD8C
has been or is being used with this device.
Total Attenuation - The total attenuation is displayed. This is the total amount
of attenuation applied by the remote gain block.
Link Group - It is possible to link the remote gain block to other remote gain
blocks. When these remote gain blocks are linked, their WR5 attenuation and RD8C as-
signments will track. This allows for room-combining where the WR5's gains should track each other.
