|Condition||Normal Wear & Tear|
Cosmetically the plastic end caps are damaged (very common for the Crest LM-12 see photo) however, that does not effect the performance/working condition at all on this unit. This includes two power supplies and case. Any further information such as manuals are available at Crest's website.Find It on UsedLighting.com
Crest Century Series LM
Safety Considerations Each new Power Supply is shipped with the AC third wire ground connected to the console chassis ground. The connection is made at the rear of the Power Supply unit. This is necessary for safety reasons so that exposed metal parts are grounded. In the event of a live conductor making contact with the console chassis or the Power Supply chassis then the current will flow to ground without a safety hazard arising.
Note that when the console is disconnected from the Power Supply the chassis ground connection to AC third wire ground is broken and safety protection is lost. For uninterpretable grounding, in a fixed installation for example, make a connection directly to the console chassis from the safety ground.
Disconnect the ground link on the rear of the Power Supply. This disconnects console ground from Power Supply AC third wire ground which would otherwise create a hum-loop.
Samples the channel's signal pre-fader and allows for monitoring within the master section of the console. This signal is not affected by the Mute Switch. When depressed, the signal level can be seen on the output 12 meter, and heard via the mixer's headphone or local monitor output.
When this PFL Switch is depressed, the channel PEAK LED indicator illuminates at a lower intensity. When used as a status indicator of switch position, the Peak LED indicating circuit remains fully operational by illuminating at a much higher intensity than when indicating PFL status.
PEAK LED Indicator
Illuminates RED when any of the points monitored come within 3db of the clipping point. Signal is sampled after the input preamplifier stage, after the EQ section, and after the fader. This LED also serves as a PFL ON indicator, but at a much lower intensity than when it is used to indicate clipping.
LM-20 (LM-8+4) INPUT MODULE
This module serves as the input module for LM-20 and the now discontinued LM-8+4. The only difference between the two is the factory default settings on the dual concentric sends.For the LM-20 the sends are set for level/level operation. For an LM- 8+4 the sends are set for level/pan operation.
