4. CONNECTIONS 4.1. BA-800 Connection Examples [Note]: Be sure to plug the power cord into the 120VAC wall outlet. If the power voltage differs, the equipment may not work properly or fires or electrical shocks may result.
4.2. BA-806 Connection Examples [Note]: Be sure to plug the power cord into the 120VAC wall outlet. If the power voltage differs, the equipment may not work properly or fires or electrical shocks may result.
4.3. BA-823 CONNECTION EXAMPLE [Note]: Be sure to plug the power cord into the 120VAC wall outlet. If the power voltage differs, the equipment may not work properly or fires or electrical shocks may result.
4.4. Speaker Connections [BA-806] Low-impedance speakers (4 to 16 OUTPUT Low impedance speakers (4 to 16 When connecting two or more speakers, make sure that the total speaker impedance is greater than 4 .. (If two 8 speakers are connected in parallel, the total impedance is 4 ). High-impedance speakers have to be connected to the 70V or 25V terminal. 1. Connection to the 70V terminal Parallel connection (Total impedance has to be greater than 83 or total wattage less than 60W.) 2.
4.5. Speaker Connections [BA-823] OUTPUT SPEAKER (RIGHT) SPEAKER (LEFT) Low impedance speakers (4 to 16 The type of speakers connectable to each channel are those with impedance of over 4 . When connecting multiple speakers, the total speaker impedance must be over 4 . If under 4 , a protective circuit is triggered to prevent the equipment's normal operation, or equipment failures will occur. Use speakers with permissible input of over 30W.
5. OPERATION [BA-800, BA-806 and BA-823] Check for proper connection of the power cord, speaker cables, etc. Set each volume control to minimum position. Set the tone control to center position. (BA-806/BA-823) Set each of the following switches to desired position: AGC switch: Refer to p.18. Track sequence selection switch: Refer to p.20. Blank skip switch: Refer to p.26. Link switch: Refer to p.21~22. Set the Dolby NR switch to ON to play a tape recorded with Dolby B-type noise reduction. 5.1.
(3) Tape Ejection and Loading Press the eject button to eject the tape. When inserting a new tape, set the Dolby NR switch to ON or OFF depending on whether or not the tape has been recorded using the Dolby NR. [Note]: ( 1 ) Tape can be ejected only when the power is ON. (It cannot be ejected if power is OFF.) (2) When both cassette player units (TAPE 1 and 2) are loaded with tapes, if the tape being played back is ejected, other tape is played back. TAPE 1 ejected. TAPE 2 ejected.
(6) Microphone Announcements [BA-806 and BA-823] Connect a microphone to the microphone input terminal located on the rear panel. Set the power switch to ON, and confirm that the power indicator lights. Adjust the microphone volume control. Making an announcement during tape play triggers an internal microphone-activated muting circuit, and the tape output volume automatically decreases by approximately 20dB. The tape volume automatically returns to a previous level after announcement completion.
5.2. Track Sequence Selection [BA-800, BA-806 and BA-823] When both cassette player units (TAPE 1 and 2) are used, the tapes can be played back in order of side A-A-B-B or A-B-A-B, which is selectable by means of the track sequence selection switch. (1) Alternate A-A-B-B Playback With the track sequence switch set to A-A-B-B position, both cassette player units first play back side A of their respective tapes, and then side B, starting with TAPE 1.
6. EXPANSION Connection of the BA-800 (BA-806 or BA-823) to the BA-800 increases the number of usable cassette player units from two to four, which repeat plays in turn. 6.1. Connections (1) Expansion using one BA-800 Set both link switches to ON.
(2) Expansion using two BA-800's Set all link switches to on.
6.2. Operation of an Expanded System Follow the procedures below to operate the BA-806 expanded by using two BA-800 units. (The operation is quite similar to that which is required when using two BA-800 units to expand the BA-800, BA-806 or BA-823.) (1) Playback Operation Set all power switches to ON. Insert tapes into cassette player units to use. Each cassette player unit plays in turn, starting with TAPE 1 (TAPE 2 if TAPE 1 is not loaded with a tape) of the unit of which play button has been pressed.
[Note]: (1) If the play button of other connected player is pressed during playback, its tape starts to run and tape travel indicator lights. In this event, the highest priority is given to the BA-806, followed by the BA-800 connected directly to the BA-806, and the remaining BA-800 unit. (2) Even if the BA-800's play button is left ON in the above examples, tapes can be switched from one cassette player unit to another.
6.3. Timer Connection When Expanded Even when the system is expanded, a timer can be used to control ON/OFF operation of tape playback. In this event, play begins with the component the timer is connected to. [Note]: Connect all the timer stop input terminals to each other. Otherwise, the tape may not stop. Timer Connection Example No-voltage make contact of program timer, etc. 2nd BA-800 for expansion 1st BA-800 for expansion Connect all the timer stop input terminals.
7. FAULT INDICATION [BA-800, BA-806 and BA-823] If a cassette player unit (TAPE 1 or 2) malfunctions, the corresponding tape travel indicator flashes. Tape travel indicator TAPE 1 TAPE 2 Flashes when TAPE 1 deck malfunctions. Flashes when TAPE 2 deck malfunctions. If either indicator flashes, make no further attempt to use the corresponding cassette player unit. Eject the tape immediately and replace the faulty cassette player unit with a new one.
9. CASSETTE PLAYER UNIT (CU-800) REPLACEMENT Revolving parts of a unit mechanism are impaired with extended use, downgrading the sound quality. The CU800's life is approximately 2,000 hours, which can be made 4,000 hours (500 days for 8 hours per day) by using two units alternately. Whenever possible, attempt to use both units of the BA-800, BA-806 or BA-823 to make overall unit life longer. If the unit is used for more than 1,000 hours and the sound quality deteriorates, replace it with a new unit.
11. TROUBLESHOOTING Although some failures can be traced to legitimate mechanical faults, some are in fact the results of improper maintenance, tape defects or lack of experience in operating the player. If you think that there is a failure, refer first to the following checklist.
120V AC, 60Hz.
