Bose AmPlus 50 Supplement Manual page 26

2.3 Place the Page Assign Switch S6
positions 1 and 4 to the enable position
(toward J2). This will enable the Page
1 & 2 outputs.
2.4 Place the Page 1 and 2 Mix Level
potentiometers R5 and R6 fully CCW.
2.5 Connect the Channel 1 output of the
AmPlus™ 100 Amplifier at J6 to an Oscillo-
scope so you can visually monitor the
signal.
2.6 Apply a 1 Vrms, 1 kHz signal to the
Channel 1 Page Input at J1 of the
Opti-Voice ® Page Option Card.
2.7 The Page 1 top LED should be lit,
indicating a page input. You should also
see a clean sine wave displayed on the
Oscilloscope.
2.8 Turn the Page 1 Gain Pot clockwise
slowly. At about the 12 o'clock position, the
top Page 1 LED should change color from
green to red to indicate an overload
condition.
2.9 Repeat these tests for Channel 2.
3. Page Assignment Tests
3.1 Set up the AmPlus 100 Amplifier and
the Opti-Voice Page Option Card as listed
in the Test Setup Notes.
3.2 Place switch S6 positions 2 & 3 to the
enabled position (toward J2). This will
enable Page 1 to Zone 2 and Page 2 to
Zone 1.
3.3 Apply a 10 mVrms, 1 kHz signal to the
Channel 1 Page Input at J1.
3.4 Measure the Channel 2 output level at
J6 of the AmPlus 100 Amplifier. It should be
5.75 Vrms ± 0.5 Vrms.
3.5 Apply a 10 mVrms, 1kHz signal to the
Channel 2 Page Input at J1.
TEST PROCEDURES
26
3.6 Measure the Channel 1 output level at
J6 of the AmPlus 100 Amplifier. It should
be 5.75 Vrms ± 0.5 Vrms.
4. Line Output Gain and Switching Tests
4.1 Set up the AmPlus 100 Amplifier and
the Opti-Voice Page Option Card as listed
in the Test Setup Notes.
4.2 On the Page Card, move switches S5
positions 1 and 4 to the ENABLED (toward
J2) position. This will enable the Line
Outputs of the Page Option Card.
4.3 Place S3 and S4, Opti-Voice Enable
switches, to the ON (toward J2) position.
Note: Be sure that S6 positions 1-4 are not
enabled, as the output signal will be dis-
torted.
4.4 Apply a 10 mVrms, 1 kHz signal to the
Page Card inputs at J1 Channel 1.
4.5 Measure the output level at Channel 1
of J3 at the Page Card. It should be
1.75 Vrms ± 0.5 Vrms.
4.6 Repeat these tests for Channel 2.
4.7 Move switches S5 positions 1 and 4
back to the DISABLE (away from J2)
position.
4.8 Move switches S5 positions 2 and 3 to
the ENABLE (toward J2) position. This will
allow the Channel 1 Page to be directed to
the Channel 2 output and the Channel 2
Page Input to be directed to the Channel 1
output.
4.9 Apply a 10 mVrms, 1 kHz signal to the
Page Card inputs at J1 Channel 1.
4.10 Measure the output level at Channel 2
of J3 at the Page Card. It should be
1.75 Vrms ± 0.5 Vrms.
