Lectrosonics AV 62, Руководство по эксплуатации, Страница: 15 / 20

Host sends command - 12
Host sends 1 data byte - desired memory
Host receives 19 bytes: Bytes 1-6: Program input gain for inputs 1-6. Data ranges from 0-31, with 0 corre
sponding to maximum gain, 30 to minimum gain, and 31 to input off.
Bytes 7-8: Mic input gain for mics 1 and 2. Data ranges from 0-63, with 0 corresponding
to maximum gain, 62 to minimum gain, and 63 to mic input off.
Byte 9: Program bass level. Data ranges from 0 to 8, where 0 corresponds to 10dB
boost, 4 is flat, and 8 is 10dB cut. Each step is 2.5dB.
Byte 10: Program treble level. Data ranges from 0 to 8, where 0 corresponds to 10dB
boost, 4 is flat, and 8 is 10dB cut. Each step is 2.5dB.
Byte 11: Mic bass level. Data ranges from 0 to 8, where 0 corresponds to 10dB boost, 4
is flat, and 8 is 10dB cut. Each step is 2.5dB.
Byte 12: Mic treble level. Data ranges from 0 to 8, where 0 corresponds to 10dB boost,
4 is flat, and 8 is 10dB cut. Each step is 2.5dB.
Byte 13: Program output gain. Data ranges from 0 to 255, where 0 corresponds to
maximum gain and 255 corresponds to minimum gain. Gain scaling is
0.333dB/bit.
Byte 14: Program output balance. Data ranges from 0 to 31, where 0 corresponds to
full right, 14 and 15 are equal left and right, and 31 is full left.
Byte 15: Mono output gain. Data ranges from 0 to 255, where 0 corresponds to maxi­
mum gain and 255 corresponds to minimum gain. Gain scaling is 0.333dB/bit.
Byte 16: Left program output mix. Bits 0, 1, and 3 are the only meaningful bits. If bit 0 is
1, the Left program output mix includes the summed signals from the left
program inputs. If bit 1 is 1 the Left program output mix includes the summed
signals from the microphone inputs. If bit 3 is 1 the Left program output mix
includes the signal from the Expansion input.
Byte 17: Right program output mix. Bits 0, 1, and 3 are the only meaningful bits. If bit 0
is 1, the Right program output mix includes the summed signals from the right
program inputs. If bit 1 is 1 the Right program output mix includes the summed
signals from the microphone inputs. If bit 3 is 1 the Right program output mix
includes the signal from the Expansion input.
Byte 18: Mono program output mix. Bits 0, 1, 3, and 5 are the only meaningful bits. If bit
0 is 1, the Mono program output mix includes the summed signals from the
microphone inputs. If bit 1 is 1 the Mono program output mix includes the
summed signals from the left program inputs. If bit 3 is 1 the Mono program
output mix includes the summed signals from the right program inputs. If bit 5
is 1 the Mono program output mix includes the signal from the Expansion input.
Byte 19: Expansion out mix. Bits 0 and 1 are the only meaningful bits. If bit 0 is 1, the
Expansion out mix includes the summed signals from the microphone inputs. If
bit 1 is 1 the Expansion out mix includes thesummed signals from the left and
right program inputs.
Program/Mic Input Commands
Get Local Mode Line Input Mixer Status - Outputs the mixer mode status associated with Local mode operation. Single
mode makes the AV62 operate like a signal switcher for program inputs. Multiple mode makes the AV62 operate like a true
audio mixer, where any number of inputs may contribute to the program output mix.
Host sends command - 20
Host receives 1 data byte: Mixer mode. 0 - Single mode (i.e. only one program input may be active at a time),
1 - Multiple mode (i.e. any number of inputs may ve simultaneously active).
Set Local Mode Line Input Mixer Status - Allows the Local mixer mode of the AV62 to be set. The new value is stored in
non-volatile memory.
Host sends command - 21
Host sends 1 data byte: Mixer mode: 0 - Single, 1 - Multiple
Host receives 1 data byte: 100, to signify the completion of storage in non-volatile memory.
Get Current Line Input Levels - Outputs the setting of the gain of the specified line level input. Input number data ranges
