7.2.2.4
Sleep Mode Section
To the right of the Channel Control section is the sleep mode section.
The user may set the signal threshold level as desired. When there is no
audio signal greater than the set threshold level at any of the eight inputs
for the time selected, the amplifier will enter the sleep mode. The main
power supplies will be turned off (but not the power to the Dante device)
just as in the standby mode. However, when a signal above the threshold level appears at any channel, the
amplifier will automatically wake from this mode and return to its operating conditions when it entered
sleep mode. There is a short time delay (approximately ½ second) before the amplifier is restored to
normal operation. Sleep mode can be defeated by selecting Never as the time interval.
7.2.2.5
Speaker Impedance Section (
–
LZ and Channels 7 & 8 of the
–
MXZ)
The Speaker Impedance section) is to the right of the Sleep Mode section. Select the
impedance that matches the speakers connected to the low impedance outputs. This
ensures that the proper signal levels are delivered to the load to prevent overdriving
the amplifier.
7.2.2.6
Power Allocation Section (
–
LZ and Channels 7 & 8 of the
–
MXZ)
The low impedance output models (
–
LZ Model and Channels 7 & 8 of the
–
MXZ model) allow the user to
allocate different audio power levels for each channel. As delivered, each channel is allocated 50W
rms
.
Larger spaces may require more power while smaller ones may require less. The Power Allocation Section
provides the means to setting these power levels. However there are certain limitations.
•
The total power available to channels 1-4 is 200W
rms
•
The total power available for channels 5-8 is 200W
rms
•
No channel may be allocated more than 125W
rms
Note that only channels 7 and 8 of the MXZ Model are low impedance. However, the total power
available for channels 5-8 is still 200W
rms
. Subtract the total allocated power for channels 7 and 8 from
200W to determine the maximum tapped wattage for
all
high impedance speakers attached to channels
5 and 6.
To adjust the power allocated to a channel, select the desired power
level from the dropdown list. Proceed through all channels making
certain that the total allocated power in group 1 (channels 1-4) is less
than or equal to 200W and that the total allocated power in group 2
(channels 5-8) is also less than or equal to 200W.
