DM1624 Input Compressor Commands
incpatt Input compressor attack time
incpgn Input compressor gain
incpmug Input compressor makeup gain
incprat Input compressor ratio
incprel Input compressor release time
incpthr Input compressor threshold level
incpatt (input compressor attack time)
This command may be used as a query to read the
attack time, or as an update to set the attack time. The
input channel is specified by using the address syntax.
Addresses must be in the range 1 to 16. The data type
is integer, in the range 5 to 2000, representing the time
in one tenth millisecond increments.
Examples:
REQUEST RESPONSE
QUERY incpatt(1)? OK 42
UPDATE incpatt(15)=30 OK
incpgn (input compressor gain)
This command may be used as a query to read the
compressor gain. The input channel is specified by
using the address syntax. Addresses must be in the
range 1 to 16. The data type is integer, representing the
gain in dB, which is always a negative value if the
compressor is active, or zero.
Example:
REQUEST RESPONSE
QUERY incpgn(1)? OK -5
incpmug (input compressor makeup gain)
This command may be used as a query to read the
makeup gain, or as an update to set the makeup gain.
The input channel is specified by using the address
syntax. Addresses must be in the range 1 to 16. The
data type is integer, in the range 0 to 30, representing
the gain in dB. The allowable upper limit of makeup gain
values is dynamically determined by the threshold and
ratio settings of the compressor, and may be less than
the absolute maximum of 30 dB. If the value sent in an
update request exceeds this upper limit, it will be forced
to the limit value.
Examples:
REQUEST RESPONSE
QUERY incpmug(1)? OK 5
UPDATE incpmug(15)=12 OK
incprat (input compressor ratio)
This command may be used as a query to read the
ratio, or as an update to set the ratio. The input channel
is specified by using the address syntax. Addresses
must be in the range 1 to 16. The data type is float, in
the range 0.0 to 50.0, representing the compression
ratio, with 0.0 meaning that the compressor is “off”.
Examples:
REQUEST RESPONSE
QUERY incprat(1)? OK 2.1
UPDATE incprat(15)=5.55 OK
incprel (input compressor release time)
This command may be used as a query to read the
attack time, or as an update to set the attack time. The
input channel is specified by using the address syntax.
Addresses must be in the range 1 to 16. The data type
is integer, in the range 100 to 10000, representing the
time in one tenth millisecond increments.
Examples:
REQUEST RESPONSE
QUERY incprel(1)? OK 500
UPDATE incprel(15)=2000 OK
incpthr (input compressor threshold level)
This command may be used as a query to read the
threshold, or as an update to set the threshold. The
input channel is specified by using the address syntax.
Addresses must be in the range 1 to 16. The data type
is integer, in the range -80 to +20, representing the level
in dBu.
Examples:
REQUEST RESPONSE
QUERY incpthr(1)? OK -3
UPDATE incpthr(15)=-20 OK
