About This Listing Working digital meters with green and red lights to give you a visual example of how much wattage you are pumping to your speakers. There are two of them in this listing for sale.

One meter has a missing speaker clip. It would be an easy fix, or maybe just run without it. They are a nice visual representation for gauging what your running. They gauge up to Watts. This item is sold As-Described This item is sold As-Described and cannot be returned unless it arrives in a condition different from how it was described or photographed. So, if I hook the meter upto set B, will I be ok?

ToTo Man , May 13, YOu can parallel it with the A speakers if you like, since that's what you want to measure. The meter itself does not load the amplifier.

COnnecting in parallel with the "A" speakers will work for sure, connecting to the "B" speaker output will probably work too. You can use thin wire to connect it and be sure to set the meter impedance switch to the setting that most closely matches your main speakers.

It will present no load, no impeadance, and no problems whatsoever so long as you run it within the APM's power handling capability. If you open the APM up you'll see that the left and right sides are totally seperate from each other and thus will not present a problem to amplifiers that are descrete, balanced, grounded, etc.

It's just like connecting an extra speaker except it's invisible to the amp. It's a fool-proof connection - I call it the "Monkey Connection".

So simple even a monkey can make the connection. JimmyNeutron , May 14, Messages: 11, Location: Area code OvenMaster , May 14, Messages: 1, Location: Cincinnati, Ohio. I had a wpc watt meter once and a watt analogue. The was a digi and that's how I knew the SX driving 4 ohm subwoofers would crank out watts thermal no problem. Can't believe I sold that monster. It had great ballistics for a cheap rat shack meter :thmbsp:.

Well I hooked it upto set B and it works. At my loudest listening levels the 3rd LED is pretty constant and the 4th LED flickers from time to time, so I guess thats in the 15wpc range for 8ohms.

Incidently I just measured my speakers by hooking up a multimeter to the binding posts and I'm getting a reading of about 3. My speakers are quoted as '4 to 8 ohms', and I was kinda hoping they'd be in the upper of the that range but they're obviously not :thumbsdn:. According to the power meter manual you've to double the value to get the wpc for a 4ohm load, which would put me in the 30wpc range for 4ohms. My speakers are rated at w max so I guess I'm still well within my limits.

My amp is quoted as wpc 8ohms and wpc 6ohms obviously not brave enough to quote values for 4ohms , so again I guess I'm still well within my limits unless the wpc quoted is BPC wpc!. As well as preserving my speakers, I wanted to hook the meter up to confirm that I do in fact listen to Concert DVDs at higher volumes than normal stereo music on my vintage rig, and it confirms that I do. The power needles on my vintage Yamaha never dance any higher than 10wpc 8ohm 20wpc 4ohm.

But I don't know why I do this. Perhaps my subconcieous is telling me that concerts deserved to be cranked more than normal studio recordings in order to achieve 'concert atmosphere'. Incidentally, when you run set A and set B at the same time on your amp, aside from impedance, does it half the total power the amp can output before clipping or does it not get affected?

ToTo Man , May 14, I'd only do this for a few seconds to see how many watts my loudest listening level is, then I'd switch the meter off. If what I suggest is not safe then I'll follow you advice and hook it upto Set A ToTo Man , May 16, You must log in or sign up to reply here.
