  • Page 9 Dear Friend and Valued Customer Dear REL Owner, REL are incredibly excited about these newer HT models. Whilst the originals were exceptionally well-received by reviewers and customers alike, we had learned so much from our development of the latest Serie S and Serie T/x models that we felt certain we could effect real improvements if we applied some of these to our HT’s.
  • Page 10 4 Crossover: Used to adjust crossover frequency. Variable between 30-200Hz. 5 Level: Volume control for Input. 6 RCA Output: Used to connect or “daisy chain” another REL in tandem. 7 Left & Right Channel Low-Level RCA Input: Used to connect low-level signals to the sub-bass system from the output of a preamplifier, integrated amplifier or receiver.
  • Page 12 Phase Switch The phase control on a REL has two positions, 0 and 180. One of these positions will set the REL in phase with the speakers, and one will set it out of phase. The labels 0 and 180 are just labels and tell us nothing about the rest of the system, only if the REL is working with the speakers or not.
  • Page 13 REL Set-Up Made Simple With the REL HT/MKII, there are two basic ways to connect and setup. The first is a single channel input from the sub out of a theater or power speaker system. In this case a single RCA cable is needed. The second is a stereo input from a stereo preamp or powered speaker system.
  • Page 14 While playing music with true low bass, adjust the crossover to a point where the REL and the speaker are sure to share frequencies at 50Hz on the crossover control, or slightly higher for smaller speakers. At this point turn the LEVEL control up so that both the REL and speaker are roughly equal in volume and then...
  • Page 15 To determine the crossover point, take the volume of the REL (using the Level control) all the way down, and put the crossover to 1/4 of the rotation. At this point, bring the REL’s volume back up slowly to the point where you have achieved a subtle balance, i.e.
  • Page 16 A thermal overload device is fitted to all HT/MKII Sub-Bass Systems. If the unit is deliberately over-driven this device will sense the temperature rise and cut the output; recovery time is approximately five minutes.
  • Page 17 The HT/MKII features a standby mode that is enabled when the mode switch on the rear of the unit is set to the “STANDBY” position. In this mode, the input signal is constantly monitored for audio activity. If not audio information is detected over a period of 30 minutes, the unit will enter a low power standby mode in which less power is consumed.
