DSP SIS Commands
Common Symbol Definitions
]
=
CR/LF (carriage return/line feed), or
Carriage return with line feed (hex 0D 0A)
}
=
Carriage return or pipe symbol (no line feed, hex 0D), or
Carriage return with no line feed (no line feed, hex 0D) (for URL-encoded commands, use the
pipe character, | , instead)
E
=
Escape key, or hex 1B (use W instead of
E for web browsers, or at any time)
|
= Pipe (vertical bar) character (URL equivalent to carriage return)
•
= Space
*
=
Asterisk character (which is a command character, not a variable)
NOTE: For commands and examples of computer or device responses used in this guide, the
character “0” is the number zero and “O” is the capital letter “o.”

Additional description
Audio Trim, Gain, and Mixing
NOTES:
• The command format is the same, regardless of the control or mix-point that is to be set; the acceptable adjustment range
varies depending on the control or mix-point:
• All
X6! values are in 0.1 dB increments. Example: 56 = 5.6 dB.
•
The valid range of the level for a specific contr
ol depends on the control addressed:
• The line audio input gain range is –18 dB to +24 dB (X6! = –180 to +240).
• The mic input gain range is –18 dB to 80 dB (X6! = –180 to +800).
• The line input trim and line output trim range is –12 to +12 dB (X6! = –120 to +120).
• The mic pre-mixer gain, line out post-switcher gain, and pre-mixer gain range is –100 dB to +12 dB (X6! = –1000 to +120).
• The mix-points (with their associated mixing controls) range is –35 dB to +25 dB (X6! = –350 to +250).
• The line output gain range is –100 to 0 dB (X6! = –1000 to 0).
•
For attenuation, the negative sign (–) must be enter
ed and is reported in the response. For gain, the positive sign (+) is optional
and is not returned in the response.
Set an analog DSP trim,
gain, or mix-point
EGX6)*X6!AU} DsGX6)*X6!] Set object ID (X6)) to a level of X6!.
Example 1:
EG30012*56AU} DsG 30012*56]
Set the input 7 left gain to a value of 5.6
dB.
Example 2:
EG20800*–125AU} DsG 20800*–125]
Set the mic input 1 gain to a level of
–12.5 dB.
Read an analog DSP
trim or mix-point
EGX6)AU} X6!] Object ID X6) is set to a value of X6!.
Example 1:
EG50005AU} 105]
Post-switcher output 4 right is set to
+10.5 dB.
Example 2:
EG60301AU} –955]
Output 1 amplified audio output is set to
-95.5 dB. This response is not possible
on an MA model switcher.
Set a digital DSP trim,
gain, or mix-point
EHX6)*X6!AU} DsHX6)*X6!] Set object ID (X6)) to a level of X6!.
Example:
EH60204*-780AU} DsH 60204*-780]
Set the output 3 left digital DTP gain to a
value of –78 dB.
KEY: X6) = Object ID (gain control or mix-point) See the table beginning on page138.
X6! = Level value -100.0 dB to +80.0 dB, in 0.1 dB increments. Example: 56 = 5.6 dB.
NOTE: The valid range of the
X6!
level for a specific control depends on the control addressed.
