AMPLIFIER, TRANSFORMER, AND POWER REQUIREMENTS:
1.
CAUTION: For reasons of safety, an AC 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 for stability. The amplifier must be used in a
dry area at least 10’ away from the pool, and must be connected to a GFCI protected AC outlet
having “test/reset” buttons only.
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
(cage mount) and LL916H (nylon harness) underwater speakers are rated at
20 volts rms
maximum, and are fitted with a special 3-pin connector that connects to mating connector on
Lubell transformer boxes. Do not exceed wattage rating printed on the Lubell transformer box
label as this is unsafe and will likely burn out the underwater speaker and/or the amplifier.
USE THE APPROPRIATE TRANSFORMER BOX:

AC102C:
For connection to
SPEAKER OUT
connector on UL listed powered mixers and power
amplifiers up to 200 watts @ 8 ohms (40 Vrms) per channel. Lowers voltage to 20 volt rating of
speaker.
AC202C:
Included with the
StageMan amplifier (part of CAWSS System), or for connection to Lubell
approved amplifiers
rated up to 50 watts @ 8 ohms, or 100 watts @ 4 ohms (20 Vrms). 1/4” mono
phone jack input.
AC205B:
Included with the Lubell 9484, screw terminal I/O for permanent installations. Or can be
supplied with the Lubell OP1 jack plate for semi-permanent installations utilizing outlet box.
AC205C:
For connection to the Peavey PVi4B powered mixer, or to other UL or ETL listed
commercial sound amplifiers rated up to (but not exceeding) 78 watts rms @ 8 ohms (25 Vrms). Also
compatible with 25V constant-voltage amplfiers -- allow 37.5 watts power consumption for each
LL916 / AC205C connected in parallel. Use Bosch PLE-1P120-US amplifier or PLE-2MA120-US
powered mixer for 1-3 speakers, and PLE-1P240-US amplifier or PLE-2MA240-US powered mixer
for 4-6 speakers.
AC203E Circuit Master:
Included with the LL916 Basic System, or for connection to the 8 ohm
output of UL listed powered mixers up to 78 watts per channel @ 8 ohms (25 Vrms). Has one 3-pin
underwater speaker output jack for Lubell LL916C/H, and one 8 ohm air speaker output jack (1/4")
with 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 control on box.
AC211 Circuit Master:
For connection to the 8 ohm output of UL listed powered mixers up to 200
watts per channel @ 8 ohms (40 Vrms). Has one 3-pin underwater speaker output jack for Lubell
LL916C/H,and one 8 ohm air speaker output jack (1/4") with 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 control on box.
