Re: [SlimDevices: Audiophiles] Not impressed with the Transporter
By the way, how big of a room do you have the 703s in? Could you have to much speaker for the size room they are in or not enough furniture/rugs/wall treatments to control excess upper and mid-bass reflections? Last thoughts on the Tranporter, could you take it and an SB3 to your local HiFi shop with a laptop? The entire room is about 24'x12' but only half is used for a listening/tv area the other area is using for dining. It's possible that I don't have enough furniture...I'm a bachelor :) I also thought about visiting my dealer as he's pretty good about letting me play with his stuff but the truth is I'm pretty happy with my setup the way it is. I left the Transporter playing all night yesterday and all day today while I'm at work.

[SlimDevices: Audiophiles] Transporter vs. old Audiolab gain/sensitivity
Hi, Currently I have my TP connected via RCA to an Audiolab 8000S in pre/power mode which again is connected to an Audiolab 8000P and everything is bi-amped to my speakers. (I know, it's not true bi-amping, and although I at the time thought it was beneficial, I don't really know anymore) I've decided I want to have a go at eliminating the 8000S and running the TP directly via RCA to the 8000P. One problem is I don't know the gain and sensitivity of the 8000P. The Audiolabs are from the original series produced in the 90's. The official data for the newer series are here: http://www.audiolab.co.uk/model.php?id=3# Does anybody know if the data for the old ones are the same? I tried google but it isn't always clear whether its the new or old ones being refered to. And I don't want to blow up anything. Also I had a look at http://wiki.slimdevices.com/index.cgi?ConnectToPowerAmp and although I probably could understand it, I would be glad if anyone could just tell the attenuation setting I need to use on the TP :) Thanks for your answers.

Can't help you with the 8000P data you're looking for, but it's not actually necessary to know it. 1. Connect the TP directly to the 8000P. 2. Before powering up the 8000P, turn the volume right down on the TP. 3. Now switch on the 8000P, and start playing something. 4. Gradually increase the volume on the TP until you achieve the loudest playback you're ever likely to want. (If you get to full volume and it's not loud enough, you need an active preamp). 5. Note the dB attenuation reported on the TP's display. This is the amount of attenuation you need. 6. Power everything down, open up the TP and set the internal attenuation accordingly. Provided you make sure you start with the volume right down, you'll be fine. -- cliveb Transporter - ATC SCM100A cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=46329 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] Bi- and vertical-amping
SadieKate wrote: Does anyone know of a good but simple article on this topic? Bi-amping usually means putting an electronic crossover after the preamp. It splits the signals (stereo) into a high-frequency path and a low frequncy path, which are then sent to separate amps, and on to the speakers directly to the woofer and tweeter connections. To do this, you need speakers that can have their internal connection and crossover be bypassed. In theory, amplifying the treble in one amp, and the bass in another, will reduce distortion and make the load on each amp easier. You run separate speaker cables, so the audio signals don't have any chance to interfere. So you have one preamp, the electronic crossover, two power amps, two sets of speaker cables. I suppose you could extend this to three or four amps, if your speakers have that many connections, and your budget is sufficiently large. -- Pat Farrell http://www.pfarrell.com/ ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

You are fine here - you want maximum voltage (not power) transfer in line-level audio, so making sure the load input impedance is at least 10 times the source output impedance is the guideline here when using unbalanced connections.

You'd be sending the whole signal to each amp, and on to the tweeter or woofer. What's the tweeter going to do with a 50Hz signal? In theory, it takes much less power to drive tweeters, so you could have a 20 watt amp for the highs and a 400 watt amp for the woofer.
