9、d. The power indicator comes on as soon as the power is supplied. ) PowER rNDrcAToR This comes on as soon as the SR-gs power switch is set to ON to indicate that power is being supplied. nevenBERATtoN EFFEcT tNDtcAToR This displays the reverberation effect graphically. When the reverberation time is

10、 increased (the reverb time control is rotated clockwise), the winking intervals of the light are lengthened. Converly, when this tirne is reduced (the reverb time control is rotated counter- clockwise), these intervals are cut short. Also, the lighting area increases in proportion to the size of th

11、e reverberation components. This area is increased as the depth control is rotated clockwise. The reverb time and depth controls are t to the preferred posi- tion as you check out the reverberation, but if the re- verberation indicators circle of light remains on the display, it means that the rever

12、beration components are excessive (too much of an echol Use this as a base for adiustments. ) REVERBERATION ON SWITCH Depres this svvitcft to produce a reverberation effect with the signals fed from the REVERBERATION INPUT jacks. The reverberation effect indicator will come on, and signals featuring

13、 a reverberation effect only will be fed out from the model SR9s OUTPUT jacks. ) REVERBERATION ON-RECORDING swtTcH Depres this switch when recording a program souroe whose signals feature a reverberation effect onto a tape in a deck connected to the mode SR9s TAPE iacks. This will allow signals with

14、 the reverberating sound to be made availabe from both the SR-9s OUTPUT iacks and the TAPE REC jacks. nevenBERATroN oFF swrrcH Depress this switch to cut off the reverberation effect. This will allow signals without a reverberating sound to be made available from both the sR-9s OUTPUT iacks and the

15、TAPE PLAY iacks. NOTE: The rcverberation on $titch, the reverberation on-recording switch and the reverbration off swih are all couplel. When you depres one switch, make stre that all the odn arc re lead. Do not depress morc than one switch at a time. e) repe MoNtToR rNDrcAToR This comes on when the

16、 tape monitor switch is de- presed. TAPE MONTTOR SWTTCH Depress this switch to monitor the sound on the tape as it is being recorded or when playing back a tape using a tape deck connected to the SR-9s TAPE iacks. (The tape monitor indicator comes on.) o REVERB T|ME CONTROL This is used to adiust th

17、e delay time. The reverberation effect becomes more pronounced when this control is rotated clockwi as you listen to the reproduced sound. Listen to the sound and then set this control for the optimum effect. Selection can be made between two types of reverberation with the model SR-9 by pushing the

18、 reverb time control or pulling it out. Pushing the control gives EFFECT 1 (longer reverberation time) and pulling it out gives EFFECT 2 (one reverberation component). oeprx coNTRoL This is used to adjust the depth of the reverberation. When it is set to the 0 position, only the original sound will

19、be heard. The reverberation component increases as this control is rotated clockwise. Listen to the sound as it reverberates and adiust this control to the optimum Position.
