Operating Settings
MSCLVL is the music level. It can be OFF or a value between -79 and 0. If set at -80, it will be ”OFF”. If both
MULTIZONE and ZONELINK are ON, the corresponding zone needs to be specied.
MICLVL is the microphone level. It can be OFF or a value between -79 and 0. If set at -80, it will be ”OFF”. If
MULTIZONE is ON, the corresponding zone needs to be specied.
MAXMSCLVL is the maximum music level. If the music level is adjusted above the maximum, it will be changed to
the maximum value. In case both MULTIZONE and ZONELINK are ON, there sll are 2 dierent values possible for
zone 1 and zone 2. The dierence between those 2 levels will determine the oset between the volumes of both
zones. The maximum dierence in this mode is 40. Example:
SET MAXMSCLVL ZONE1 -16<CR>
SET MAXMSCLVL ZONE2 -10<CR>
Now, the volume can be adjusted between OFF and -10. The level in zone 1 will always be 6 dB lower than the level
in zone 2.
MAXMICLVL is the maximum microphone level. If the microphone level is adjusted above the maximum, it will be
changed to the maximum value.
SELECT is the source selecon. The source selecon in both zones is always the same, so it’s never needed to
specify the zone
Equalizer
Also the equalizer sengs are the same for both zones.
EQBASS sets the level of the bass.
EQTREB sets the level of the treble.
The value must be between -14 and 14 in steps of 2. If a dierent value is used, it will get changed to the closest
match.
Configuration Settings
AUTOLD is Auto Loudness and this is only acve in Stereo mode. It will adjust the equalizer depending of the
volume seng. If the auto loudness is on, the sound will sll be more “rich” at low levels.
PAGACT is paging acve. If set on, the microphone will only be on when there is a contact between pin A or B and
the ground of the connector at the backside of the amplier (see user manual). In that case, the music will be
muted as well. The Concept 1 will also send ”PAGING (ZONEx) ON/OFF<CR>” when the contacts are closed/opened
so the user can know the status.
IPGAIN is input gain. Each source input has its own gain seng so the source (A, B, C or D) needs to be specied.
The value can be between -20 and 14 in steps of 2. If an invalid value is used or no source is specied, “ERROR:
Value Invalid!<CR>” will be replied. Otherwise, the reply will be “Command Exicuted!<CR>”
ZONESPLIT is only used in MULTIZONE mode. Default, the zone split value is o, which means that le and right of
the sources will be mono summed in MULTIZONE mode. Some users would like to have a dierent music in each
zone by plugging dierent sources for le and right. By seng ZONESPLIT on, the le input will be sent to zone1
and right input to zone 2, like in stereo mode. This way, it’s possible to have dierent music in each zone but please
note that the source select will always impact both zones. The ZONESPLIT feature is implemented starng from
V1.0.2
