Meyer 500-HP Speaker Rental

Acoustical
Operating Frequency Range: 35 Hz – 140 Hz
Note: Recommended maximum operating frequency range. Response depends on loading conditions and room acoustics.
Frequency Response: 36 Hz – 130 Hz ±4 dB
Note: Measured free field with 1/3 octave frequency resolution at 4 meters.
Phase Response: 45 Hz to 125 Hz ±30°
Maximum Peak SPL: 135 dB
Note: Measured with music, referred to 1 meter, half-space loading.
Dynamic Range: >110 dB
Coverage: 360° for a single unit; varies with number of units and configurations

Transducers
Low Frequency: Two 12” cone drivers with ceramic magnets
Nominal impedance: 2Ω
Voice coil size: 4”
Power-handling capability: 1200 W (AES) each
Note: Power handling measured using AES standards: transducer driven continuously for two hours with band limited noise signal having a 6 dB peak-average ratio.

Audio Input
Type: Differential, electronically balanced
Maximum Common Mode Range: ±15 V DC, clamped to earth for voltage transient protection
Connectors: Female XLR input with male XLR loop output or VEAM all-in-one (integrates AC, audio, and network)
Input Impedance: 10 kΩ differential between pins 2 and 3
Wiring
Pin 1: Chassis/earth through 220 kΩ, 1000 pF, 15 V clamp network to provide virtual ground lift at audio frequencies
Pin 2: Signal +
Pin 3: Signal – (optional polarity switch)
Case: Earth ground and chassis
Note: An additional input module option is available with a polarity switch and an attenuator (0 dB to –18 dB).
DC Blocking: Differential DC blocking up to maximum common mode voltage
CMRR: >50 dB, typically 80 dB (50 Hz – 500 Hz)
RF Filter
Common mode: 425 kHz
Differential mode: 142 kHz
TIM Filter: <80 kHz, integral to signal processing
Nominal Input Sensitivity: 0 dBV (1 V rms, 1.4 V peak) continuous is typically the onset of limiting for noise and music
Input Level: Audio source must be capable of producing +20 dBV (10 V rms, 14 V peak) into 600Ω to produce the maximum peak SPL over the operating bandwidth of the loudspeaker

Amplifier
Type: Two-channel complementary MOSFET output stages (class AB/H)
Output Power: 1800 W total (2 x 900 W)
Note: Wattage rating based on the maximum unclipped burst sine-wave rms voltage the amplifier will produce into the nominal load impedance; both channels 42 V rms into 2 ohms.
Total Output: 3600 W peak
Note: Peak power based on the maximum unclipped peak voltage that the amplifier will produce for at least 100 milliseconds into the nominal load impedance; both channels, 60 V peak into 2 ohms.
THD, IM TIM: <.02%
Load Capacity: 2 Ω each channel
Cooling: Convection at low to mid audio levels; fan-assisted only at high audio levels
Note: Fan controlled by audio level; remains off at turn-on and at low to mid audio levels. Fan operation at high audio levels makes it virtually inaudible.

Power
Connectors: PowerCon with looping output or VEAM all-in-one (integrates AC, audio, and network)
Voltage Selection: Automatic, two ranges, each with high-low voltage tap (uninterrupted)
Safety Agency Rated Operating Voltage: 95–125 VAC; 208–235 VAC; 50/60 Hz
Turn On/Turn Off Points: 85–134 VAC; 165–264 VAC
Note: 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.

Current Draw
Idle Current: 0.49A rms (115 VAC); 0.26A rms (230 VAC); 0.55A rms (100 VAC)
Maximum Long-Term Continuous Current: 8.4A rms (115 VAC); 4.2A rms (230 VAC); 9.7A rms (100 VAC)
Burst Current 18A rms (115 VAC); 9A rms (230 VAC); 21A rms (100 VAC)
Note: AC power cabling must be of sufficient gauge so that under burst current rms conditions, cable transmission losses do not    cause the voltage to drop below specified operating range at the speaker.
Ultimate Short-Term Peak Current: 40A peak (115 VAC); 22A peak (230 VAC); 46A peak (100 VAC)
Inrush Current: 10A peak (115 VAC); 13A peak (230 VAC); 10A peak (100 VAC)
Note: Current draw for a single loudspeaker. Loop output not used.
