Meyer Sound UPA-1P Powered Speaker
Its extraordinarily flat amplitude and phase response ensure tonal accuracy and precise imaging over a wide, symmetrical listening area. This predictable array performance allows for maximum system design flexibility.
The UPA-1 is ideal for concert halls, clubs, houses of worship, theatrical sound reinforcement, portable and installed audio-visual systems, and cinema surround sound and effects.

RMS Network (Optional): Equipped for two-conductor, twisted-pair network, reporting amplifier operating parameters to system operator’s host computer.
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. At this frequency, the mid- and highfrequency transducers produce equal sound pressure levels.
5. 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.
6. 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.
7. Amplifier wattage rating based on the maximum unclipped burst sinewave rms voltage that the amplifier will produce into the nominal load impedance. Low channel 30 V rms (42 V pk) into 2 ohms; high channel 32 V rms (45 V pk) into 16 ohms.
8. 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 intermittent operation.
