• Despite SQ-Rack’s faderless design, there are no compromises when it comes to control.
• The SQ-Rack’s faders screen provides instant access to level controls, plus 8 SoftKeys and 4 Soft Rotaries—all assignable with LCD displays—so you get to choose which functions you have at your fingertips.
• The SQ MixPad app for Android, iOS, Windows, and macOS provides access to the SQ-Rack’s mixing functions from anywhere in the venue, with an offline mode allowing preparation of scenes or shows away from the venue.
• For less technical users, the SQ-Control app provides simplified access in-app in addition to a dedicated screen on the SQ-Rack itself. SQ-Control can be configured by an admin user to deliver just the right amount of control for each application or dry hire, whether that’s single fader control of background music from behind the bar or controlling live stream levels in a house of worship.

• Every input has HPF, a super-fast gate with sidechain and filter, a musical 4-band parametric equalizer with RTA, and Peak/RMS compressor for control and shaping of levels and transients.
• Mixes have both a parametric and 28-band graphic EQ along with compressor as standard, all ready to switch in when required.

Whether you’re equipping a venue, a touring band taking it to the next level, or building a professional in-ear monitoring system, the SQ-Rack is built for any challenge. From installations in bars to cruise ships, or integration with larger systems to bands on the move and IEM/pro touring, SQ-Rack is the ultimate solution to provide crystal-clear sound, every time.

The ultimate IEM mixer
