REL Acoustics ST 5 User Manual Most functions are accessible via either the remote or the front panel. Standby and the memory are only accessible via the remote. Display timeout, display brightness and DC trigger are only accessible via the front panel. To prevent accidental changing of parameters once they have been set, the manual encoder on the front panel can be electronically locked.
REL Acoustics ST 5 User Manual Display of Memory Function 1st. memory position store. Press MEMORY the display will show Pr – (Profile) Press LFE + button, the display will show Pr –1 and the settings will be stored. 1st. memory position recall. Press MEMORY the display will show Pr – (Profile) Press LFE - button, the display will show Pr 1 and the settings will be recalled. Repeat the above procedure for memory positions 2,3 and 4 using the HIGH LEVEL, FREQUENCY and SLAM/DEPTH + and – buttons.
REL Acoustics ST 5 User Manual CONTROL PANEL DISPLAY The following options are available via the remote control and the encoder on the control panel. LFE input volume. Select by pressing LFE + or – buttons on the remote control or pressing the control knob on the control panel until ‘LF’ shows on the display. Adjust level by pressing the + or – buttons on the remote control or rotating the control knob on the control panel. Level will show in the range 00 to 99 High Level input volume.
REL Acoustics ST 5 User Manual Use this function to lock the control panel encoder, this will prevent user settings being changed accidentally. Press MEMORY and then LFE MUTE buttons, display will read FP on or FP oF. FP on means front panel control active, FP oF means front panel control locked. Pressing the standby button on the remote control switches the sub bass unit in or out of standby mode. Press the STANDBY button and the display will read Stby briefly and then default to just four flashing dots.
REL Acoustics ST 5 User Manual CONNECTING UP Always switch off your system before disconnecting any wires To enhance connection versatility, the “St” range has a range of separate inputs depending on the model, see page 8. To connect to the power amplifier using the UNBALANCED Neutrik high level input. To engage the Neutrik Speakon plug, insert fully into socket and rotate clockwise until locked.
REL Acoustics ST 5 User Manual To connect to MONO BLOCK power amplifiers using the High Level Neutrik UNBALANCED input To engage the Neutrik Speakon plug, insert fully into socket and rotate clockwise until locked. To remove the Neutrik Speakon plug, grip body of plug, place thumb on chrome lever, move lever backwards rotate the plug anti-clockwise (counter-clockwise in the US) a quarter turn and withdraw.
REL Acoustics ST 5 User Manual To connect to the amplifier/processor/receiver using the phono to phono LFE interconnect Alternative method for connecting at Low Level from pre amplifier In some circumstances it is not possible to use the high level method of connection, for example when using active speakers.
REL Acoustics ST 5 User Manual REL SET-UP MADE SIMPLE REL designs are not traditional subwoofers, but true sub-bass systems. A REL is designed to augment the performance of “full range” speaker systems, to provide linear response down to below 12 Hz (Studio III, -6 dB down at 9 Hz). Therefore, for the moment, set aside everything you’ve been taught about subwoofers and how they are integrated into a stereo or theatre system. REL’s set-up and positioning differs from other subwoofers.
REL Acoustics ST 5 User Manual Trying to ignore all other music in the cut, listen for the bass drum and its effect on the listening room. 1. Phase Orientation: Once in the corner we need to adjust for phase. This may be the single most critical step, and because it really is quite simple, it is often over looked by even the most experienced audiophiles. The right phase is whichever position is the loudest or fullest.
REL Acoustics ST 5 User Manual Hint: There is a tendency among audiophiles to set the crossover point too high and the gain too low when first learning how to integrate a REL with the system, the fear being one of overwhelming the main speakers with bass. But in doing so, the resulting set-up will be lacking in bass depth and dynamics. The proper crossover point and gain setting will increase overall dynamics, allow for extended bass frequencies, and improve soundstage properties.
REL Acoustics ST 5 User Manual RUNNING IN Care taken over running in will be rewarded by many years of pleasurable use. Both the electronics and the drive unit will benefit from an initial period of carefully controlled use. Possible damage may be sustained by running in the unit at too high a volume setting over an extended period. On the other hand, by taking a little care over this initial period - about 24 hours of actual use - a longer life with a higher potential eventual performance is assured.
REL Acoustics ST 5 User Manual POWER SAVING EFFICIENCY All REL sub-bass systems are designed for maximum power efficiency, when operational and also when at rest. REL circuitry is designed for “power starvation” operation when no signal is present. However it remains at maximum readiness to respond immediately to a sudden transient signal, such as an explosion in a movie, even after an extended period of rest and at whatever level.
