Key Features
• 6 Balanced microphone inputs / 6 Aux inputs / 1 Music input
• 100V standard with optional 70V and 4-16Ω outputs
• Bass and treble tone controls
• Multi stage thermally cued fan cooling
• Robust design incorporating latest Mosfet technology
• VOX muting on inputs 1 and 2 (Switch selectable internally)
• Phantom power on microphone inputs (DIP switch selectable internally)
Designed for applications requiring up to six microphone inputs, without compromising output power and overall performance. Each model features inputs which can be configured for either microphone or line level operation. Bass/treble controls, phantom powering and adjustable input sensitivity enable unparalleled flexibility for a wide scope of applications such as factories, workshops, mine sites, sports clubs and office buildings.
