Question about Audio Players & Recorders
I have a Kenwood stereo of model number UD-505. I have attached two main speakers to the unit, as instructed in the owner's manual. I have then attached a centre speaker to the surround speakers port The speaker is hooked up to my TV through an RCA connection. I've been having a problem where whichever mode I choose, Dolby Surround, Pro Logic or 3-Speaker, I can't get the speakers to all work together. The large speakers work and the small centre speaker doesn't or the other way around. This speaker system in about 10 years old, so I haven't had any luck finding help anywhere else. Fingers crossed and thanks in advance.

Try resetting the unit by unplugging the unit from the wall, then plugging it in again WHILST holding the power on/standby button in. This should reset the system. If not:

SOURCE: Want to use my current speakers with a new surround sound system. Current system is 5.1 channels, rated at 100w per channel @ 8. Ohms. New System is rated 145watts, 5.2 channels at 6 Ohms. Will b ok?
8 Ohm speakers will work just fine as replacements for the
6 ohm speakers. When fitting speakers you need to consider
The power handling capability. The impedance and the frequencies
involved. Power handling is expressed in wattage ie 100W.
Unfortunately this can be expressed in rms, max or peak music. The rms value (root mean square) is the only really relevant figure as this is the continuose handling power at 1 KHz. The impedance
is the resistance that the amp sees but is not a dc resistance and
varies with frequency. The lower the impedance the more power
will be drawn from the amp. In the event of a short circuit across
the speaker the amp will try to deliver infinite power into an infinitly
small load in an infinitesimal amount of time and will self destruct.
Using an 8 Ohm speaker draws less power than a 6 Ohm speaker.
Connecting speakers in parallel; results in the impedance beingreduced. For example two 8 Ohm speakers in parallel will result
in a 4 Ohm impedance load but in series will be 16 Ohms.
Incidentally the the .1 (5.1) is the sub woofer which only has
to handle the bass frequencies, a small percentage of the
amplifiers overall frequency response..
Connect your speakers and then power up the amp last
after double checking there are no shorts on the speaker
All the very best from Vintie.
