Specifications
- The TXn/ACD1 will return two lines of character strings if successful.
The first line will be a character string of "RSPR OK" or "RSVL OK".
For details on the character strings "PRM" and "VOL" in the second line, see chapter 3.2.1.
Ignore the first line but see only the second line to find a value after a parameter is changed for a controller.
A value returned in the second line is the changed value (absolute quantity). Even a relative setting will not return the quantity changed.
- If unsuccessful, the TXn/ACD1 will return a one-line character string, either "RSPR ERR" or "RSVL ERR."
E.g.) ACK if the value of TXn parameter (Att chA, Access ID 0000/10/0000/0100 ) was successfully increased from -20dB by 30 steps (dB-table)
RSPR OK
PRM 0 0000/10/0000/0100 -170
ACK if an attempt to increase the value of TXn parameter (Att chA, Access ID 0000/10/0000/0100 ) from -20dB by 30 steps (dB-table) has failed
RSPR ERR
ACK if the value of TXn parameter (Matrix Input ch2, Access ID 0104/00/0100/0000 )
was successfully decreased from -20dB by 10 steps (curve-table method, max. 10dB)
RSVL OK
VOL 0 0104/00/0100/0000 413
ACK if an attempt to decrease the value of TXn parameter (Matrix Input ch2, Access ID 0104/00/0100/0000 )
from -20dB by 10 steps (curve-table method, max. 10dB) has failed

The command names stand for "Get Parameter" and "Get Volume" respectively.
- If sending to a TXn, [AMP ID] is always 0. If sending to an ACD1, [AMP ID] is the AMP ID (0 to 39) assigned to the amp to be controlled.
- [Access ID] is the 17 strings including "/" of the parameter to be controlled. (See separate parameter map.)
- One or more spaces are needed between the command and the option, and between the options.
- This command cannot get the value of a library-protected parameter. Attempt to do so will return an error.
E.g.) To get the value of TXn parameter (Att chA, Access ID 0000/10/0000/0100 ):
GPR 0 0000/10/0000/0100
To the get value of TXn parameter (Matrix Input ch2, Access ID 0104/00/0100/0000 ), using curve-table method:
GVL 0 0104/00/0100/0000
- The TXn/ACD1 will return two lines of character strings if successful.
The first line will have a character string: "GPR OK" or "GVL OK".
For details on the character strings "PRM" and "VOL" in the second line, see chapter 3.2.1.
The first line can be ignored; check the second line to find the parameter value for a controller.
- The TXn/ACD1 will return a one-line character string of either "GPR ERR" or "GVL ERR" if unsuccessful.
E.g.) ACK if successful in getting the value of TXn parameter (Att chA, Access ID 0000/10/0000/0100 ) -30dB (dB-table method)
GPR OK
PRM 0 0000/10/0000/0100 -300
ACK if unsuccessful in getting the value of TXn(Att chA, Access ID 0000/10/0000/0100 ) (dB-table method)
GPR ERR
ACK if successful in getting the value of TXn parameter (Att chA, Access ID 0000/10/0000/0100 ) -30dB (curve-table method, max. 10dB)
GVL OK
VOL 0 0104/00/0100/0000 323
ACK if unsuccessful in getting the value of TXn parameter (Att chA, Access ID 0000/10/0000/0100 ) (curve-table method, max. 10dB)
