• extensive source and speaker selection
• several monitoring modes (mono, stereo, Ø, M/S, with sub)
• convenient integrated talkback system
• integrated headphone amplifier with SPL's proprietary Phonitor Matrix
  
• adjustable crossfeed to tailor the phonitor matrix to individual needs
• additional feed path for an individual artist mix
• internal audio operating voltage of +/-18 volts for high-quality analog audio processing
• 45mm large, massive, milled aluminum knob for analog volume control
• three pairs of outputs for stereo speakers and one mono output for a subwoofer (or mono speakers)
• subwoofer can be combined with all stereo speaker pairs (cutoff frequency has to be adjusted at the sub)
• separate dim and mute switches (also for headphones)
