MUSIC setting but highly satisfactory nonetheless The MUSIC setting reproduces sound in all three front speakers when a strongly centered or mono signal is present This is an excellent choice for heavily centered pop music such as metal and sounds more natural for broadcast material with a single announcer OFF sets the center channel level to 4 5dB less than the front left and right speakers and then leaves the level unchanged as the steering varies This setting is equivalent to conventional stereo with a slight center fill HALL SIZE allows you to select room sizes of lengths ranging from 4 38 meters depending on the effect selected INPUT BALANCE allows you to compensate for the occasional source with audible channel imbalance When selected screen graphics indicate the relative left right position LIVENESS adjusts the amount of recirculation within the effect Higher values mimic more reflective surfaces in the simulated space and increase the amount of time it takes the sound to decay At very high values the decay is audibly less smooth than in the Church and Cathedral Effects which are more effective at simulating very live spaces 41 PCM Effects and Parameters Lexicon LOW FREQ WIDTH allows you to apply low frequency spatial correc tion to the signal Positive values of LOW FREQ Width indicate that the difference signal L R has additional energy below 500Hz while the sum L R has correspondingly less Negative
12. No Video Make sure that video cables particularly S Video cables are fully inserted and that the appropriate connector is assigned to the VIDEO IN parameter in the Input Configuration menu Hum Finding and eliminating audio hum in a complex installation can be a very frustrating task Often the easiest way to identify the culprit s is to systematically eliminate devices from the audio chain If Cable TV is connected to any component in the system start by unplugging the Cable completely preferably right at the wall jack If this eliminates or greatly reduces the hum itis worth a call to your Cable company A quick fix assuming your cable is round 75Q wire is to attach a 75 300Q transformer to the end then attach a 300 750 transformer to that so that the end is back to a round 75Q wire There are commercially available antenna lead isolators which may provide additional insulation from electrical surges Interference with Radio or TV The MC 1 does generate minimal amounts of RF energy and is in compliance with FCC rules and CE standards If some interfering noise is noted move AM loop and FM T type antennas away from the MC 1 and reorient them as necessary Use shielded cable for FM and TV antenna feeds Erratic recall of modes Severe power surges or sags can confuse the MC 1 memory To correct or if you simply want to start over restore the factory defaults with the procedure described at the end of this section If all else fail
