Extron electronics DTP CrossPoint 4K Series - Audio trim, gain, and mixing

DTP CrossPoint 4K Series Matrix Switchers • DSP SIS Commands 168
NOTE: X8) = Object ID (gain control or mix-point) See OID table, beginning on page 161.
X8! = Level value (depends on control) -100.0 dB to +80.0 dB, in 0.1 dB increments. Example: 56 = 5.6 dB.
X8@ = Mute and phantom power status 0 = unmute (pass audio) or off 1 = mute or on

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
X8!
values are in 0.1 dB increments. Example: 56 = 5.6 dB.
• The valid range of the level for a specific control depends on the control addressed:
• The line audio input gain range is –18 dB to +24 dB (
X8!
= –180 to +240).
•
The mic input gain range is –18 dB to 80 dB (
X8!
= –180 to +800).
• The line input trim and line output trim range is –12 to +12 dB (
X8!
= –120 to +120).
• The mic pre-mixer gain, line out post-switcher gain, and pre-mixer gain range is –100 dB to +12 dB (
X8!
= –1000 to +120).
• The mix-points (with their associated mixing controls) range is –35 dB to +25 dB (
X8!
= –350 to +250).
•
The line output gain range is –100 to 0 dB (
X8!
= –1000 to 0).
• For attenuation, the negative sign (–) must be entered and is reported in the response. For gain, the positive sign (+) is optional and
is not returned in the response.
