Question about Rotel Audio Players & Recorders
Just got RA 840bx4 off ebay ($174), if switch for bypassing tone control/mono is used, may or may not cause R speaker to cut out, if R not working, sl. pressure back to centre (cutout) position will Bring R back online and MAY stay operational. Also no manual & would like to know wattage output with remote speakers engaged/disengaged. At moment trying to compare sound quality against NAD 3020i (unfortunately using NAD T512 DVD/etc player), waiting on Rotel RCD 930AX from EBAY in next couple of Days. Speakers - Tannoy Mercury M2 on stands, Richter wizards - not sure of year model, oblong speaker grills not oval, also have pair Richter bookshelfs about 15-16 inches high - no serial no.
PROBLEM ; audition sound quality with one amp, then need to disconnect player from 1 amp and reconnect to 2nd amp, repeat for speakers, then restart music and try to recal quality, CONSIDERING switchbox from **** smith/Tandy(YUK) to speed up A/B comparison listening times, (BUT, likely big loss of quality due to switchbox, therefore wasted effort/time) .
CDs - James Blunt, Dark side Moon, Roger Waters ''Amused to Death'' (INCREDIBLE Q Sound - Try it, Warning; lyrics pretty likely to offend untill you work out the deeper story -?''Concept Album'' like Dark Side...), Dire Straits, DMP music catalogue-supposedly somewhat like HDCD/SACD-seems hi quality, Loreena McKennett -''Themask and the mirror''. Thanks for Advice/Wisdom in advance.
Rotel Amp supposedly in all working condition, irritated by Tone cutout switch prob. but supposedly good amp at OK price, Maybe local Audio Fixit guy would be option for switch unless minor symptom of MAJOR problem. 1 New amp, so many considerations!
Lets try the simple stuff first. This whole problem could be caused by a dirty switch contact. Pick up some electronics cleaner from a local electronics shop and spray the switch (from the inside of the unit). Work the switch on/off a number of times then respray one more time. That should clean out any dirt that is there. Try the unit again and hopefully the problem is resolved. If not, then the switch itself may need to be replaced. When you get the cleaner, get one that contains a lubricant as well. This will help to prevent the problem from coming back again.
