Naca5, Direction Arrow & Plus Sign

Make sure you get this bit right!

If in order to plug the cable in you have to turn it upside down, simply remove the screw pull out the connectors rotate 180 and reasemble, the points will now be correct.

If the cable was made up for you by your dealer then you may simpy need to swap the cables round at the amp end in order for evrything to go together properly.

The arrows should point towards the speaker for all the difference it makes.

The arrow indicates directionality - from amp to speakers.

Along one of the joined cables there should be a ridge - this is the positive side.

Steve.

The proof of the pudding...

hi,

wats a ridge??

my connection is in dis manner.

for the left channel cable :
positive from amp --> cable WITH arrow pointin towards speaker--> positive of speaker
negative from amp --> cable WITHOUT arrow point --> negative of speaker

for the right channel cable :
positive from amp --> cable WITHOUT arrow pointin towards speaker--> positive of speaker
negative from amp --> cable WITH arrow point --> negative of speaker

is it ok....

yo guys,

to perfect the current setup, i have dismantle the cable box & revert the positive sign to the cable ridge tat has the arrow sign.

now both my cable positive polarity has the arrow along the ridge & towards the speaker. setup of speaker cable is complete.

but alas.... now the sound seem nt right.... guess have to burn-in the whole setup/cables again for few more dae b4 it sound right

btw im usin the come-wif grey naic for my nacd5 to nait5... is there a better version of the default grey naic?? heard tat the is these snaic - black.... but seem like the pin is slighly different & is nt meant for connection of nacd5 & nait5...

Is tat so???

yours is the newer one, and the newer one has a tinge of lavender and is a little thicker than the older one. the older ones have been obsolete since the late 1990s.

vik.

On the one hand, it is important that the signal flow in the direction of the arrow. Yet, on the other hand, you are saying that it does not matter which conductor is the + and which is the -, as long as they are in phase.

Very well, but electrons travel up one conductor in one direction and down the other conductor in the opposite direction, no? Hence, that arrow doesn't mean a thing unless you get the absolute polarity right. get it wrong, and your electrons are traveling retrograde the directionality of the conductor, no?

educate me on this point. It's been driving me crazy for months.

Of course, it's a AC signal, afterall, no?

Hi justin,

mi kinda agree wif tats y i was crazy for these s well... now after the swap... which is all the arrow towards speaker is to the positive polarity.... the sound dun seem to sound quite rite...

the original connection is the right speaker cable was connected in a way which the arrow sign was towards the negative.... & its has been runnin for 2 days alreadi.

now after the swap... how long do i need to run in the cable to its correct soundin.. hehee btw does the factory do run in speaker cable b4 being put up for sale?? if there is then it means i have to run in the cable for a very very long time alreadi!!!

*sign*

have got it all rite now!!! thanks 2 my wonderful dealer!!! Thanks man!!!

where this leaves the signal earthing of systems that don't have a turntable in them, as many are nowerdays obviously, is somewhat unclear! I suspect in an all-Naim system, the answer is Floating!

I've wondered about this too. You would think that Naim could wire up a switch (a nice recessed slider type) on the back of their sources - tuner, CD, that connects the mains ground to -ve. With an explanation in the manual of course. That way you can choose to make one of those the ground to earth for the whole system. Maybe a switch would be just an other thing to add noise, then how about an internal jumper for the dealer to add if he knows that you won't be using a TT or, these days, to cut if knows you are.

Richard,

Naim CD players earth their signal leads. This means a standard install with LP12 & Naim CD has an earth loop.

In fact, I believe Naim tuners are earthed, too, so there's another one for ya.
