  • Installed sound and system integration

Detailed Description Bias Q1.5+

Bias Q1.5+ combines four amplifier channels with integrated processing in a lightweight 1U chassis. The published output at 8 Ω is 600 W per channel, with separate ratings for other loads and bridged operation. Smart Rails Management and a microprocessor-controlled supply with power factor correction support efficient operation across a wide mains-voltage range.

The amplifier supports both low-impedance loads from 2 Ω and 70/100 V distributed systems. ArmoníaPlus provides processing, preset access and monitoring, including FIR optimisation and loudspeaker protection tools. DSP+ variants add AES67 networking. Automatic power sharing supports unequal channel loads, and WM Touch compatibility provides a control option for installation systems.
