USW-1P specifications

1. Recommended maximum operating

frequency range. Response depends on

loading conditions and room acoustics.

2. Free field, measured with 1/3-octave

frequency resolution at 4 meters.

3. Measured with music at 1 meter.

4. Power handling is measured under AES

standard conditions: transducer driven

continuously for two hours with band-

limited noise signal having a

6 dB peak-average ratio.

5. Two additional input module options

are available with a polarity reversal

switch and an attenuator (0 dB to

-18 dB): one looping and one with two

inputs for mono summing.

6. Amplifier wattage rating based on the

maximum unclipped burst sine-wave

rms voltage that the amplifier will pro

duce into the nominal load impedance.

Both channels 32 V rms (42 V pk) into

4 ohms.

7. No automatic turn-off voltages.

Voltages above 265 V AC are fuse

protected but may cause permanent

damage to the power supply. Voltages

below 90 V AC may result in intermit-

tent operation.

The loudspeaker shall be a self-powered, sub-bass system

which may be flown singly or groundstacked with multiple cabi

nets. The transducers shall consist of two 15-inch cone drivers

with 3-inch voice coils.

The loudspeaker shall incorporate internal processing electron

ics and a two-channel amplifier. Each amplifier channel shall be

class AB/bridged with complementary MOSFET output stages.

Burst capability shall be 550 watts total with a nominal resistive

load of 4 ohms both channels. Distortion (THD, IM, TIM) shall

not exceed 0.02%.

Performance specifications for a typical production unit shall

be as follows: Operating frequency range shall be 32 Hz to 200

Hz. Phase response shall be ±30 degrees from 45 Hz to 155 Hz.

Maximum peak SPL shall be 135 dB at 1 meter. Beamwidth shall

be 360 degrees for a single unit. Directional characteristics can

be achieved with multiple cabinets.

Notes:

The audio input shall be electronically balanced with a 10 kOhm

impedance and accept a nominal 0 dBV (1 V rms, 1.4 V pk) signal
