Bias Q2
Négy csatornás erősítő
Főbb jellemzők:
- The four channel Bias Q2 DSP+D amplifier provides reliable premier-grade power and headroom in the smallest possible package size.
Alkalmazások:
The Bias Q2 has favourably smaller dimensions and a lighter weight while still being reliably durable and maintaining an impressive sound quality.
A high efficiency microprocessor-controlled power supply with built in PFC (Power Factor Correction) allows flawless worldwide operation with any AC mains voltage in the range of 85-275 VAC, tolerant to peak up to 400 V. The patented SRM (Smart Rails Management) technology maximises the efficiency, while drastically reducing power consumption at any load and usage condition. A secondary, highly efficient power supply keeps the system responsive at any operating condition, so that system checks and monitoring can be performed even in stand-by and deep-sleep modes.
Designed to work with lo-Z (from 2 Ω) and with 70V/100V distributed lines, any mixed configuration of low and high impedance output loads can be achieved, making the Bias Q2 suitable for all applications in installed sound reinforcement systems.
DSP+D versions of the Bias Q2 extend system performance, with the support of Dante™ digital audio networking architecture and the on-board, high-end signal processing.
