TEST PROCEDURES
10.2 Connect 32 Ohm, 300 W loads to the
channel 1 - 4 outputs.
10.3 Apply a 1 kHz, -19.3 dBV input to the
channel 1 - 4 input jacks.
10.4 Measure the output level at the channel
1 - 4 output jacks. It should be +19 dBV
+/- 1 dBV.
10.5 Decrease the signal input level to attain
a 0 dBV output from channels 1 - 4.
10.6 With the above signal applied, rotate
the channel 1 - 4 OUTPUT ATTEN controls
from zero to - infinity. Verify that the output
level decreases from 0 dBV to infinity.
11. Input Priority Test
11.1 Using a CAT-5 cable, connect a Bose
®
CC-1 ControlCenter Zone Controller to the
ControlCenter RJ-45 jack on the rear panel.
Refer to the table on page 12 for part num-
bers for the CC-1 controller.
11.2 Set the Output 1 and 2 DIP switches to
Hi-Z mode (left). Set the GLOBAL OUT DIP
switch to 100V (right).
11.3 Connect 32 Ohm, 300 W loads to the
channel 1 and 2 outputs.
11.4 Apply a 1 kHz, -19.3 dBV input to the
channel 1 and 2 RCA input jacks.
11.5 Measure the output level at the channel
1 and 2 output jacks. It should be +31 dBV
+/- 1 dBV.
11.6 With the above signal applied, rotate
the CC-1 volume control from maximum
volume (fully CW) to minimum (fully CCW).
Verify that the output level decreases from
+ 31 dBV to 0 dBV.
12. Mute Control Test
12.1 Connect the black 2-pin mute conn-
ector to a SPST toggle switch. Plug the
mute connector into the MUTE jack on the
amplifier rear panel.
12.2 Set the Output 1 and 2 DIP switches to
Hi-Z mode (left). Set the GLOBAL OUT DIP
switch to 100V (right).
12.3 Connect 32 Ohm, 300 W loads to the
channel 1 and 2 outputs.
12.4 Apply a 1 kHz, -19.3 dBV input to the
channel 1 and 2 RCA input jacks.
12.5 Measure the output level at the channel
1 and 2 output jacks. It should be +19 dBV
+/- 1 dBV.
12.6 With the above signal applied, close the
SPST toggle switch. Verify that the output
level immediately decreases from +19 dBV
to 0 dBV. Open the switch and verify that the
output level returns to +19 dBV.
13. Auto Standby Test
13.1 Set the AUTO STANDBY DIP switch on
the rear panel to the ON position. Set the
Output 1 and 2 DIP switches to Hi-Z mode
(left). Set the GLOBAL OUT DIP switch to
100V (right). Set the SENSITIVITY DIP
switch to 4 dBu (left).
13.2 Connect 32 Ohm, 300 W loads to the
channel 1 and 2 outputs.
13.3 Apply a 1 kHz, -19.3 dBV input to the
channel 1 and 2 RCA input jacks.
13.4 Measure the output level at the channel
1 and 2 output jacks. It should be +19 dBV
+/- 1 dBV.
13.5 Reduce the input signal level to < -55.2
dBV. Verify that after a 20 minute period that
the amplifier switches to standby mode.
13.6 Increase the input signal level above
-55.2 dBV. Verify that the amplifier comes
out of standby mode after about 2 seconds.
