Quested SBC800 – Low Frequency Management System 800W

The Quested SBC800 Low Frequency Management System improves the low frequency response of any music or film reference monitoring system. The 800 watt amplifier comes coupled with the ideal collection of phase and crossover control to help any studio get the perfect low frequency response for their room. With independently adjustable control of gain and phase on Left/Centre/Right and Low Frequency Effects channels, plus 2 bands of EQ to optimise system performance in any environment, it brings a new level of performance to this area of reference monitoring.

Quested’s 800 watt LFE/Sub-Bass Controller is the perfect Bass Management tool for music and film production. Left/Centre/Right Inputs, phase control, 2 bands of parametric EQ for room troubleshooting and enough power and connectivity to drive three of Quested’s (or other brand) X12 or X15 Subwoofers from a single SBC800. Easy to set-up, the SBC800 Class D amplifier technology runs extremely cool indeed. No noisy fans, just clean, powerful bass for your mixes.

Full crossover functionality, phase control from 0-180 degrees, and a Class D amplifier delivering 800 watts to one or two subwoofers adds up to a serious offering in the SBC800.

Setting up a flat low frequency response for a studio has always been a challenge. With the SBC800, Quested and other systems can benefit from a powerful set of tools to make it a lot less complicated.
