SoundDock 10 Digital Music System
Functional Tests
Equipment Required
Audio Signal Generator
Notes:
1. Begin the test with no power applied.
2. Confirm the Audio Signal Generator out-
put is set to zero volts before connecting.
1. Twiddler Air Leak Test
1.1 Connect the audio signal generator to the
mini jack AUX input on the back of Sound-
Dock 10.
1.2 Set the signal generator output to:
A. Voltage = 0V
B. Frequency = 80Hz +/- 10%
1.3 Apply power to the SoundDock 10, the
system will default to the AUX input if there is
nothing connected to the dock. Press and
hold the volume plus button for 15 seconds,
this should set the system to max volume.
1.4 Set the Signal generator output to:
A. Input Voltage = 0.06Vrms +/- 10%
B. Frequency = 250Hz +/- 5Hz
1.5 Listen for air leaks around all the cabinet
seams, joints, and wire harness through-
holes.
PASS if no audible air leaks can be heard at
a distance of less than 1ft (0.3M) from any
exterior surface of the enclosure.
FAIL if any air leaks can be heard at a dis-
tance less than 1ft (0.3M) from any exterior
surface of the enclosure.

TEST PROCEDURES

2. Woofer Air Leak Test
3. Left / Right Driver Test
4. Frequency Sweep Test
22
2.1 Set the signal generator output to:
A. Input Voltage = 0.06 Vrms +/- 10%
B. Frequency = 44Hz +/- 5Hz
2.2 Listen for air leaks around all the cabinet
seams, joints, and wire harness through-
holes.
PASS if no audible air leaks can be heard at
a distance of less than 1ft (0.3M) from any
exterior surface of the enclosure.
FAIL if any air leaks can be heard at a dis-
tance less than 1ft (0.3M) from any exterior
surface of the enclosure.
3.1 Apply an input signal to the SoundDock
left channel only. Set generator as in step 1.3
and 1.4, except set the frequency to 800Hz
and confirm that only the left driver plays.
3.2 Reduce generator output to zero volts
3.3 Repeat step 3.1 for the right channel.
3.4 Reduce input signal to zero volts and
reconnect the right channel.
4.1 Set audio signal generator to:
A. Voltage = 0.06 Vrms +10%
B. Sweep range = 35Hz - 3KHz +10%
4.2 Execute the sweep for a minimum of 3
seconds up and 3 seconds down.
4.3 Listen for any extraneous noises such as
buzzes, rattles, ticks, and distortion.
PASS if no noise can be heard at a distance
of less than 1ft (0.3M).
FAIL if any noise can be heard at a distance
less than 1ft (0.3M).
4.4 Reduce the input signal to zero volts.
