Controls

  • Bed5.1 / 7.1 / 7.1.4 — The bed: 5.1, 7.1 or 7.1.4; the pins it does not use are ignored.
  • Crossover40 to 200 Hz — Where the mains hand over to the sub (40 to 200 Hz, 80 Hz as most rooms are set).
  • MainsBass Managed / Full Range — Split takes the bass off the mains; Full keeps them whole and only adds their bass to the sub.
  • LFE Gain0 dB / +10 dB — The LFE channel in the sub at +10 dB, as it is played back, or 0 dB.
  • Sub Level−12 to +12 dB — Gain on the sub (-12 to +12 dB), to match it to the room.
  • ListenAll / Sub Only / Mains Only — Plays everything, the sub alone or the mains alone.
  • Output−24 to +12 dB — Gain on every pin (-24 to +12 dB).

Best uses

  • Hear a bed the way a room with small speakers and a sub plays it
  • Check what goes to the sub and what stays in the mains
  • Monitor a 5.1 or 7.1.4 mix on speakers that do not go low
  • Set the sub level against the mains

Properties

4th-order Linkwitz-Riley crossover: the high-pass on every main channel and the low-pass on their sum add up flat (measured within 0.0001 dB from 20 Hz to 10 kHz), so the managed system sums like the full-range one, with the crossover's phase turn. The sub plays on the LFE pin. No latency. In REAPER set the track to 12 channels and route the pins to your bed. The player on this site plays pins 1 and 2 only.
