Lubell Labs LL916C Instructions Manual

AMPLIFIER, TRANSFORMER, AND POWER REQUIREMENTS:
1. CAUTION: For reasons of safety, an AC mains operated amplifier used with an underwater speaker
must meet the following minimum requirements: 1) UL or ETL label on the rear panel, 2) Grounded
3-prong power cord, 3) Proper output rating (wattage & ohms) to match Lubell transformer box
rating, 4) Class AB output circuitry recommended for stability. The amplifier and transformer box
must be used in a dry area at least 10' away from the pool, and must be connected to a GFCI
protected AC outlet.
2. CAUTION: For reasons of swimmer safety and proper amplifier operation, the Lubell underwater
speaker must be used with the correct Lubell Isolation Transformer Box. The Lubell LL916C
(caged) and LL916H (harnessed) underwater speakers are rated at 20 volts rms maximum, and
are fitted with a Conxall 3182-3PG-524 3-pin (not XLR) connector that connects to mating Conxall
4182-3SG-300 connector on Lubell transformer boxes. Pin 3 hot. Warning: Do not exceed
wattage rating printed on the Lubell transformer box label, and use/store box in dry location only.

AC102C: For connection to
amplifiers up to 200 watts @ 8 ohms (40 Vrms) per channel. Lowers amplifier voltage to 20 volt rating
of LL916C or LL916H underwater speaker. Connect two AC102C boxes / LL916C (one per channel)
to the Crown Xli 800 for full 50 meter Olympic pool coverage.
AC202C: Included with the
Lubell approved amplifiers
Vrms). 1/4" mono phone jack input; Includes HOSA SKJ-600 2 ft speaker cable with ¼ TS plugs.
AC205B: Included with the Lubell 9484 in-wall pool speaker kit. 25V screw terminal input, 20V screw
terminal output for connection to LL916-XXX underwater speaker. For connection to UL or ETL listed
commercial sound amplifier having 25V constant voltage output, allowing 37.5 watts power
consumption for each LL916 / AC205C connected in parallel. Use one Russound A2100 amplifier (8
ohm mode) to power one LL916-XXX speaker per channel (2 total), and link multiple amplifiers for
additional speaker pairs. Also available is InterM A-120 powered mixer or Bosch PLE-1P120-US
power amplifier for 1-3 speakers, and PLE-1P240-US power amplifier for 4-6 speakers.
AC205C: Same as above except ¼ in mono phone jack input and Conxall 4182-3SG-300 output for
connection to one Lubell LL916C or LL916H underwater speaker.
AC203E Circuit Master: For connection to the 4 ohm output (21.9 Vrms) of the InterM A-120 mixer
amplifier. Has single Conxall 4182-3SG-300 output connector for connection to mating Conxall
3182-3PG-524 on the Lubell LL916C or LL916H underwater speaker. Also has one 8 ohm air
speaker output jack (1/4") with autoformer volume control for connection to the EV ZX1 air speaker.
Set volume of underwater speaker using amplifier master volume control, then set volume of air
speaker using autoformer volume control on box.
AC211 Circuit Master: Same as above except 200 watt 8 ohm input rating. For a powerful 50 meter
pool competition system, connect two AC211 boxes (one per channel) to the Crown Xli 800 power
amplifier. Connect one LL916C-100 underwater speaker and one EV ZX1-90 air speaker to each
AC211 box, and position speakers at the ¼ and ¾ positions down the length of the 50 meter pool.
