Meyer Sound HD-1 (Pair)
The Meyer Sound HD-1 (Pair) high definition audio monitor is a self-powered loudspeaker designed for ultra-precise near-field monitoring. Optimized to approximate a point-source radiator, the HD-1 yields exceptionally broad directivity with a generous “sweet spot.” Its patented circuitry minimizes time delay response and deviations from linear phase.
The Meyer Sound HD-1 (Pair) incorporates a 2-channel power amplifier and a sophisticated active crossover with optimized pole-zero filters for acoustical transparency and a flat frequency response. The power amplifier features complementary MOSFET output stages and operates at class A at low to moderate levels (less than 90 dB SPL) and class AB at high levels.
The Meyer Sound HD-1 (Pair) delivers a high peak SPL with a dynamic range of over 100 dB, with extremely low distortion. Its free field frequency response is flat (within ±1 dB) from 40 Hz to 20 kHz, with each unit being individually calibrated at Meyer Sounds Berkeley, California factory. The HD-1 has an active, balanced input that is switchable between a +4 dBu and –10 dBV nominal operating level. The HD-1s transducers include a low-frequency 8-inch cone driver and a high-frequency 1-inch soft dome tweeter. The lowfrequency drivers ample magnet and 2-inch voice coil yield high efficiency with rapid heat dissipation. The tweeter employs a silkinfused dome that affords smooth frequency response while minimizing breakup and coloration. The proprietary drivers are housed in a vented cabinet and individually tested for maximum linearity and low distortion.
The loudspeaker shall be a self-powered, highdefinition studio monitor. The transducers shall include one 8-inch diameter cone driver and one 1-inch dome tweeter.
The loudspeaker system shall incorporate internal processing electronics and a 2-channel amplifier, one channel for each driver. The power amplifier shall feature complementary MOSFET output stages and operate as class A at low to moderate levels (less than 90 dB SPL) and class AB at high levels. Burst capability shall be 225 W total with a nominal 8 Ohm resistive load. Distortion (THD, IM, TIM) shall not exceed 0.02%.
Performance specifications for a typical production unit shall be as follows, measured at 1/3-octave resolution: frequency response shall be 32 Hz to 22 kHz; maximum peak SPL shall be 120 dB at 1 meter; coverage shall be 60 degrees by 60 degrees. The audio input shall be electronically balanced with a 10 kOhm impedance and accept a nominal input level of +4 dBv or –10 dBU (switchable). The audio connector shall be XLR 3-pin female.
Power requirements shall be nominal 100, 110, 220, or 240 V AC line current at 50– 60 Hz. UL and CE operating voltage range shall be 90–250 V AC. Maximum peak current draw during burst shall be 1.82 A rms at 120 V AC and 0.99 A rms at 220 V AC. The AC power connector shall be a 3-pin IEC male receptacle.
Loudspeaker components shall be mounted in an oak veneer enclosure with a smooth medium-gloss black finish. Dimensions shall be 12.00 inches wide x 16.00 inches high x 16.39 inches deep (305 mm x 406 mm x 416 mm). Weight shall be 51 lbs (23.1 kg). The loudspeaker shall be the Meyer Sound HD-1 (Pair).
