Test SetUp
70V version: Apply the positive input signal to
the red wire and the negative to the black wire.
100V version: Apply the positive input signal to
the yellow wire and the negative to the black
wire.
Connect the orange (80W) tap wire to the white
wire. After testing, return the tap setting to what
the customer had set the unit to. See sche-
matic diagram below.
1. Phase Test
1.1 Apply 8 Vdc to the speaker input terminal.
1.2 The driver should move outward.
2. Air Leak Test
2.1 Apply a 35 Vrms, 80 Hz signal to the
speaker input terminal. (Use 50 Vrms for 100V
units)
2.2 Listen for air leaks around the driver, top
cap, and base seams. Repairs can only be
made to the driver.

FS360P II Environmental Loudspeaker
3.1 Apply a 35 Vrms, 10 Hz signal to the
speaker input terminal. (Use 50 Vrms for 100V
units)
3.2. No extraneous noises such as rubbing,
scraping or ticking should be heard. To distin-
guish between normal suspension noise, rubs
and ticks, displace the cone of the driver with
your finger. If the sound can be made to go
away or get worse, it's a rub or tick and the
driver should be replaced. If the noise stays
the same, it's normal suspension noise and
will not be heard with regular program mate-
rial.
4.1 Apply a 35 Vrms, 80 Hz signal to the
speaker input terminal. (Use 50 Vrms for 100V
units). Sweep the speaker from 80 Hz to 5
kHz.
4.2 Listen for buzzes, rattles or other extrane-
ous noises from the driver or cabinet.
