Question about Audio Players & Recorders

1 Answer

I just bought a NAD C326 BEE amp which I use with a pair of rather old (20 years and somewhat battered) REGA ELA loudspeakers which I brought to the US from Europe. The problem is that the fuse in the amp keeps blowing. I listen to music for a while, and then it blows. Could it be that the loudspeakers don't fit this amp? I would love to hear from you.

    Thanks a lot.



    I have some problems finding the specifications for my loudspeakers, but here is one claim that I found on a website about the Rega Ela loudspeakers:



    "Nasty load, drops to <1 ohm in places and the sensitivity is 72dbw so you need lots of current and at least 250wpc IMO. Think big Krells - forget Naims."



    If this is true, does it mean that my loudspeakers aren't suited to match the NAD C326 BEE?



    Best,

    Thanks again. I probably need to try with another pair of speakers. I also, by the way, see on the internet this specification of my Ela Rega speakers: 89dB & 8 ohms. If correct, would that also create difficulties with my NAD C 326 BEE amplifier?

Hi,
Your NAD amplifier can handle 100w,150w,200w into 8,4,2 ohms speaker respectively. Check the speaker's wattage and resistance to verify if the unit didn't gone to overload or you may swap another speakers with much lower wattage and try if the symptoms still there. If no, yes, your REGA ELA speakers made the fuse blown, If still the symptoms persist, then this is an indication that the fault came from the amplifier itself. Make sure that the replacement fuse is the same ampere and voltage ratings. Low ampere(current) rating can't handle the ordinary working ampere of the unit once it gone to its peak performance.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

    If the information you've got is correct then yes it will stress the amplifier sound output IC which is in fact the proof of blowing the fuse. You better swap another speaker to confirm If the information has a basis at all.

I have a NAD turntable. I have noticed that on occasions there seems to be a background crackle.. Thought it was dust at first !! Have swapped the connection over where the turntable plugs into the amp....


Either you have a poor earth connection or you are getting a lot of static from the records you play. The best way of getting rid of static is a spray you can get for cleaning records. Search on-line for Anti-Static Record Cleaner.

I need leads to connect my NAD C320 BEE amplifier to PSB T45 speakers. Not sure which plugs are needed to fit into the speakers.


From the C320 manual, Page 5...

11. SPEAKERS

Speaker terminals for speakers with an impedance of 4 ohms or more. Connect the right speaker to the terminals market 'R +' and 'R-' ensuring that the 'R+' is connected to the '+' terminal on your

loudspeaker and the 'R-' is connected to the loudspeaker's '-' terminal. Connect the terminals marked 'L+' and 'L-' to the left speaker in the same way.


Always use heavy duty (16 gauge; 1.5mm, or thicker) stranded wire to connect loudspeakers to your NAD C320. The high-current binding post terminals can be used as a screw terminal for cables
terminating in spade or pin sockets or for cables with bare wire ends.

BARE WIRES AND PIN CONNECTORS

Bare wires and pin sockets should be inserted into the hole in the shaft of the terminal. Unscrew the speaker terminal's plastic bushing until the hole in the screw shaft is revealed. Insert the pin

or bare cable end into the hole and secure the cable by tightening down the terminal's bushing.

Ensure bare wire from the speaker cables does not touch the back panel or another socket. Ensure that there is only 1/2" (1cm) of bare cable or pin and no loose strands of speakers wire.

If you're pondering those jumpers on the back of the speakers, my advice is to leave them in place and ignore them. Connect the speaker cables to either plus or minus.

Bi-wiring does nothing but make you use twice as much speaker wire for the same electrical effect. Bi-amping assumes there are deficiencies in your electronics that must be worked around, again by using more speaker wire and separate amps.

I have a 3 year old Nad C315BEE which shuts down after around 20 minutes play, after it cools down and resets it`s fine, looks like a thermal cut out problem. Any ideas as to the cause. It`s not enclosed...


Does it actually FEEL hot when it shuts down? Ther could be dust bunnies inside it.

http://www.retrevo.com/support/NAD-C315BEE-Amps-manual/id/8043dj584/t/2/

These things only have so many protection cycles in their lives. If you can't find a cause for the thermal shut-down and resolve it you should take it to a tech for a check-up.

NAD C320 BEE - goes silent. Only yellow light.


Hi,
Just came accross your post accidentically, while reparing my own C320BEE. May be it 's too late for you now, but it could help others: I had the very same symptoms as you described and after a long search found out that the trouble was R45 in one of the 18V regulators. (R45: 33 ohms 1/2W fuse resistor, situated more or less half-way between the two "metal towers" on the main board. Replace by a somewhat stronger type 1W or so.
Likewise R46.)

I have a UK bought rega planar 2 turntable. I tried to use it in the USA using a step up transformer and it runs fast. How can I fix this?


As far as I can see, this turntable uses a belt. I believe the motor is synchronous (12 vac), it is designed with a pulley for working at 50Hz. At 60Hz, it turns 20% too fast. It may be possible to change the pulley as it needs to have a smaller circumference. I think you should contact a Rega representative or the company directly in the UK (www.rega.co.uk)

Right loudspeaker problem


Doesnt sound like the selector as it "sometimes" works. Redo the speaker connections on the back of the amp and speakers first. If it persists, swop the speakers and cables, if the problem swops, then it could be inside the speaker or the cable, if still the same then amp has dry joints/loose connections probably

Need a transistor spare part for NAD C340


Odd a transistor would have such a #. No 2Fanything series. It is most likely a 2SA949.... a PNP audio driver transistor.
It can be replaced by a NTE-383 (ECG383) transistor, though it's best to order the original # from a Japanese semiconductor supplier like MCM in Ohio.
It's best brought to a good hi-fi or guitar amp repir shop for a proper go-thru & repair.

NAD C340 has lost ability to switch between inputs


I have the same problem which started about a month ago and seems to be getting worse. I also noticed today, that 1 channel is significantly louder than the other - fault in the pre-amp stage, as feeding the power stage directly gives balanced, albeit extremely loud sound! Looking on eBay, I found someone else selling an amp with both problems. It would nice to think that NAD would acknowledge a design flaw, and fix for free, but my amp is 5 year old.

NAD C740 no longer reproducing music through loudspeakers


what was your amp? ic or transistorized? the output transistor of your amp may be opened, mostly it will short but because u still hear sound, maybe open and only the driver transistor are working. replacing output transistor or IC could solve the problem.
