LFR-212
LFR-212 FEATURES
INPUT
:
The LFR-212 features a female XLR Combi jack line level input marked INPUT. Balanced
1 -
connections should be used as much as possible to reduce AC HUM and interference, especially with
long cable runs.
2 -LEVEL : Control the overall level of the LFR-212 cabinet. Turn the LEVEL control clockwise to increase
gain and counter clockwise to decrease gain. Always observe the red CLIP LED on the amplifier panel.
This LED lights when a signal is clipping. Set your input level so that you have the red CLIP LED blink
occasionally and not constantly. A constant CLIP LED light indicates an over loading condition and
should be avoided. Reduce the signal level if the CLIP LED lights or blinks constantly.
3 - HF-TRIM : Allows you to tailor the LFR-212 cabinets hi end response in relation to the environment
you are in. Allows you to add or remove HF content to the signal without having to alter your patch
parameters.
4 - ILLUMINATION : Allows you to turn on or off the cabinet LED illumination.
5 - CLIP LED : Illuminates just before the amplifier begins to clip and distort. Adjust the level controls
and signal level from your source so this illuminates only briefly on peaks in the music. Using the
system with this LED on all or much of the time will result in poor sound quality and possible damage
to speakers and electronics.
6 - GROUND LIFT : Removes or reduces ground related noise arising from ground loops from using
multiple units.
7 - DI-OUT : Balanced XLR-DI out for sending your LFR-212 signal direct to the PA – no need to mic your
LFR-212. The output from the DI-OUT can be sent FRFR or CABINET EMULATED if desired.
8 - EMULATION : Allows you to select one of three modes. FRFR – gives you a FULL RANGE FLAT
RESPONSE output – totally flat and uncoloured. You can also select either a 1x12 or a 4x12 cabinet
emulation. This emulation mode also appears at the DI-OUT.
9 - AUX-IN : Use this socket for connecting an external sound source – the volume of the sound source is
controlled by its on-board volume control.
10 - LINK OUT : Use this socket to connect to an additional LFR-212. Use a good quality TRS cable to
ensure the best quality.
