Hps1000 Test Set Up And Procedure - Infinity HPS1000 Technical Manual

Amplifier/Subwoofer
Initial Control Settings
1. Audio/Video button should be on AUDIO
2. Crossover control should be set to full CW (150).
3. Phase button can be set to either setting.
4. Gain control should be set to full CCW (0)
5. Normal/Direct button should be on NORMAL.
General Function
UUT = Unit Under Test
1. Connect both right and left line level inputs (RCA) to
signal generator and UUT. Use Y-cable if necessary
from mono source. GAIN control should be full
counterclockwise.
2. Turn on generator, adjust to 100mV, 50 Hz.
3. Plug in power cord to UUT; push the main AC power
button ON. Green LED should be lit.
4. Turn GAIN control full clockwise; immediate bass
response should be heard and felt from port tube
opening.
5. Turn off generator, turn GAIN control fully
counterclockwise, disconnect RCA cables.
6. Connect one pair of speaker cables to both pairs (R)
and (L) input terminals. Cables should be connected
to an integrated amplifier fed by the signal generator.

8. Turn GAIN control full clockwise; immediate bass
response should be heard and felt from the port tube
opening.
Sweep Function
1. Follow steps 1-4 above, using a sweep generator as a
signal source.
2. Sweep generator from 20Hz to 300Hz. Listen to the
cabinet and drivers for any rattles, clicks, buzzes or any
other noises. If any unusual noises are heard, remove
driver and test.
Driver Function
1. Remove driver from cabinet following instructions on
page 10.
2. Check DC resistance of driver; it should be 6.7 ohms
+/-10%.
3. Connect a pair of speaker cables to driver terminals.
Cables should be connected to an integrated amplifier
fed by a signal generator. Turn on generator and
adjust so that speaker level output is 6.0V.
4. Sweep generator from 20Hz to 1kHz. Listen to driver
for any rubbing, buzzing, or other unusual noises.
