14,	active zone volume level (0-99)
0,	active zone mute status (1=muted, 0=unmuted)
0,	active zone bass level (-7 to +7)

0active zone treble level (-7 to +7)

[cr] is a carriage return

NOTE: IN THE EXAMPLE ZONE 2 IS PLAYING SOURCE 3; THE ZONE IS ON AT A VOLUME LEVEL OF 14%; THE ZONE IS UNMUTED; BASS AND TREBLE ARE FLAT)

3)Zone specific command – for controlling parameters of a single zone

Syntax:	zsc,[zone #],[com #][cr]
