COMPENSATEDposition.

7.Place the TAPE switch in the MONITOR position.

8.Place the PHASE switch in the 0° position.

9.Place the RUMBLE filter switch in the FLAT position.

10.Place the H.F. cutoff filter switch in the FLAT position.

11.Turn the MODE SELECTOR to the L + R TO L position.

12.While the program is playing, alternate the MODE SELECTOR between the L + R TO R and the L + R TO L position. On amplifiers such as the MC225, adjust the correct gain control until the loudspeak- ers are of equal loudness. On the MC240 or the MC275, turn the balance control until the loudspeakers are of equal

loudness.

The stereo system is now balanced. It will remain balanced through all modes of opera- tion. Leave the C22 extended on its PANLOC stops for the next series of adjustments.

ADJUSTING PHASE

1.Set the MODE SELECTOR to STEREO.

2.Turn the BASS controls and TREBLE controls to straight up position so that the dial indicator centers between the panel

markings L and R.

Stand approximately 10 feet in front of and midway between the loudspeakers. The source of sound should appear to be directly in front of you. Alternate the PHASE switch between 0° and 180°. If the sound is not directly in front of you in the 0° position, reverse the leads to one loudspeaker. The PHASE control is used to correct phase in the source material whenever necessary.

ADJUSTING BALANCE CONTROL AFTER THE SYSTEM HAS BEEN BALANCED

When these instructions have been com- pleted, the overall system is balanced and in phase; ready to deliver maximum pleasure and enjoyment.

You may hear differences in balance from one record to another or from one tape to another. Some records or tapes may be recorded with slight differences between channels. The differences can be corrected with the BALANCE control on the front panel. If the difference is heard on every record, then the cartridge may have a very small difference in output.

ADJUSTING FOR SPECIAL EFFECTS

HF CUTOFF FILTER

If you wish to reproduce old, badly worn records, you can minimize the surface noise by switching the HF cutoff filter to the IN position.

RUMBLE FILTER

If you are using a turntable or changer which has low-frequency rumble noise, you may reduce it by pushing the RUMBLE filter switch to the FILTER position.

BASS CONTROLS AND TREBLE CONTROLS

The tone balance which you hear when listening to an orchestra is affected by the conductor's instructions to his musicians, the acoustical environment in which you are listening, and your own subjective hearing interpretation. Considering these conditions, it is easy to see why tone balance controls play a major role in correcting for the follow- ing factors:

1.Each person's subjective idea of tone balance.

2.Loudspeaker frequency response charac- teristics.

3.Loudspeaker placement in the listening room.

4.The conductor's idea of tone balance at the time the recording was made.

5.The microphone frequency response char- acteristics.

6.The recording process influences.

These factors can be considered as environmental influences. The BASS CON- TROLS and TREBLE CONTROLS provide a degree of compensation for effects of en- vironment. Listen to your system with each control set with the indicators centered between the panel markings L and R. If you wish to reduce treble in relation to bass for example,turntheTREBLECONTROLScoun- terclockwise until the tone balance sounds correct to you. These controls will modify tone balance without introducing any unde - sirable effects. Do not be surprised if you find your preference in tone changing from time to time.

LOUDNESS

Due to a selective shift in sensitivity of human hearing, music reproduced at very low volume loses its bass and treble.
