Description
Meyer UPJ-1P Compact Vario Loudspeaker
The UPJ-1P pairs well with Meyer’s UPJunior, and is ideal for portable and installed audio-visual systems, theatrical sound reinforcement, frontfill and under-balcony applications, and for presentations in conference centers, ballrooms and houses of worship.

Notes:
1. Recommended maximum operating frequency range. Response depends upon loading conditions and room acoustics.
2. Measured with 1/3 octave frequency resolution at 4 meters.
3. Measured with music at 1 meter.
4. The UPJ horn can be rotated to provide an 80° x 50° coverage pattern in either the horizontal or vertical plane.
5. At this frequency, the transducers produce equal sound pressure levels.
6. The driver is coupled to an 80° x 50° constant-directivity horn.
7. 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.
8. Two additional input module options are available with polarity reversal switch and an attenuator (0 dB to -18 dB): one looping and one with two inputs for mono summing.
9. Amplifier wattage rating based on the maximum unclipped burst sine-wave rms voltage the amplifier will produce into the nominal load impedance. Low and high channels 30 V rms (42 V pk).
10. No automatic turn-off voltages. Voltages above 265 VAC are fuse protected but may cause permanent damage to the power supply. Voltages below 90 VAC may result in intermittent operation.
