Meyer Sound HD-1 High Definition Monitor Speaker
Meyer Sound HD-1 High Definition Monitor Speaker
The HD‑1 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 delays and deviations from linear phase. The HD‑1 incorporates a two-channel power amplifier and a sophisticated active crossover with optimized pole zero filters for acoustical transparency and a flat frequency response. The HD-1 : High Definition Audio Monitor 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.
Features:
- Unprecedented accuracy for mixes that translate consistently
- Exceptional transparency for fine control of EQ and effects
- Consistent, smooth coverage pattern for a very wide “sweet spot”
- Individual alignment provides matched pairs with pinpoint imaging
- Flat low-frequency response to 32 Hz without subwoofers
- High peak power minimizes distortion and compression
