USINGMICROPHONES

The SX-9000 permits the use of two microphones at once, for such purposes as recording a concert in stereo; even performances or dramas in large theaters can be efficiently recorded.

1.Turn the VOLUME - SOURCE knob all the way down if microphone recording only is desired.If mixed recording, combined with music from a record, etc., is desired,set the SOURCE knob to the best level.

2.Tii,e MIC LEVEL A knob controls the input from a microphone plugged into MIC jack A; knob B controls jack B. Tum either of these knobs to the right to increase input signal strength. Adjust the level while watching for "howling" (acoustical feedback of the speaker signal through the microphone). If this occurs, reduce the volume or separate the microphone(s) and speakers.If only one microphone is used, plug it into either jack. If setting the MIC LEVEL for another jach not being usedto

OFF, the sound will be reproduced from both speakers.

NOTE:

When adjusting the MIC LEVEL control, be careful not to cause

 

h o w l i n g .

 

Howling is of course unpleasantto hear, but it can alsodamage

 

the VU meter of your tape recorderor deck during recording .

3.If two microphones are used, the one connected to jack A will broadcast over the left channel, B the right. If you wish to use only one of these microphones at any time, tum the unused microphone level control off. Then the microphone used will broadcastover both channels.

USINGTAPE DECKS

AND TAPE RECORDERS

As shown in Fig. 9, signals heard from the speakersare normally fed to the SX-9000 TAPE REC A and B terminals. When recording, set the SELECTOR and MODE switches to your program source. Refer to the sections on Listening to Broadcasts and Listening to Records. Recording signals cannot be regulated by the SX-9000 VOLUME, BASS, TREBLE and TONE COLOR switches. These must be adjusted by the recording level control on the tape deck/tape recorder.

NOTE:

When using mono tape recorders,either the left channel signalor

 

the right channel signal may be recorded, but not both . The

 

CENTER CHANNEL terminal should thereforebe used .

TAPE MONITOR

With 2-head and 3-head type tape recorders fitted with monitor mechanisms,turning the TAPE MONITOR switch ON during recording has the following effects (if recording and playback heads are first connected): With the 2-head type, signals fed to the recording head can be monitored; with the 3-head type, signalscan be monitored immediately after recording.( SeeFig. 9. )
