I was going to recommend the Samson C-Console (can't vouch for high quality, but if it's passive, as it should be, it should be fine) except that I took a look at the literature again and it doesn't have a "mono" switch. I think you're talking about the "C-Control" and it DOES have a mono button. I've got one here on evaluation. It seems to be solidly built from strictly garden-variety components. I do like the way they illuminated the pushbuttons. It's very inexpensive. ulysses |

Cubase has a mono button right under the master faders.
Something that would be REALLY welcome in Digital Performer. Would a VST plugin help? Digital Performer needs a translator to use VST plugs, but there is a native MAS plug with DP that can do this, called Trim. It does level & panning offsets. Still, a hardware switch within arm's reach is a whole more sensible to my way of working. I like having all the control room monitor functions reside outside of the computer. Scott Fraser |

Did I really type C-Console? Yes you did. How much of it is passive? All the resistors are passive, and I'm pretty sure the capacitors are too. In fact, all of the parts in between the many JRC op amps are passive. There are some PC-mount relays in there, so at least the switching isn't solid-state. Here's the link to a picture of one without a Mono button. It's on the Internet (and even the manufacturer's web page) so it might be right. http://www.samsontech.com/products/r.../C-control.jpg Yeah. The one I have has a mono button next to the Speaker C/Sub button, which is moved over a little. I can't imagine even Samson would be dumb enough to remove the Mono button from an existing product, so I assume the photo is older than the unit I have here. I haven't had the thing apart for a while, but I think I remember all the op-amps being JRC. The majority of the board is SMT, which is what stopped me from messing with it yet. It's a double-sided board and not too easy to follow the traces around. The guy who owns it is trying to find me a schematic so I can make up my mind whether it's worthwhile to do cap and amp upgrades. I haven't measured frequency response, I have no ability to measure distortion, but the thing sounds pretty clean to me and as far as I can tell it doesn't add even the slightest bit of noise to the signal. That is, the rest of my gear is noisier. One thing that bothers me is that since all the "Left" TRS jacks are above the "Right" jacks, they're mounted on a separate board. That board has thru-hole resistors and capacitors on it, while the main board has SMT parts. Then there's a ribbon cable connecting the two. So the Left and Right signals go through slightly different signal paths. Probably not significantly different, but still different. I still wish it was passive, because it would eliminate the need to eventually build my own. This thing is under $100! ulysses |

All right, wise guy. Let me rephrase that so you can unnerstan. How much of the signal path between an input and the monitor output is passive? Does it go through any ICs? I can see that they might want to buffer the input and/or output, and I'm wondering how transparent that buffering actually is. Sorry. I was trying to say that yes, there are a bunch of op-amps in there. I must have seen about a dozen 8-pin SMT packages in there. They were a JRC part I didn't recognize, and didn't look too close, but I'd assume they were duals. There was also some junk on the separate vertically-mounted faceplate control board, including an 8-pin SIP that I couldn't get at to read. But since I don't have a schematic, I don't know exactly how many stages are in-circuit at any one time. If you look at the block diagram printed on the top of the unit (I can e-mail it to you if you like), it looks like there's a buffer amp on every input and every output. It doesn't show any amplifiers in between, but it shows a big block called "logic switching" on the inputs as well as actual switches depicted on the speaker outputs and talkback. So the input switching might actually be solid state after all. I don't know yet. I was playing with a Furman SRM-80 when that was a new product. It's a similar gadget with more bells and whistles, and I found that I could hear it in the monitor path, which is not a good thing. They dropped it for a while, and now there's a SRM-80A out, but I don't know what's different. I tried to ask at the AES show, but they only person who was likely to know was never available the several times I passed by their booth. See, I have a long history of NOT hearing stuff in the signal path. I doubt that's because I keep getting great stuff, I probably just have tin ears. I think it would be swell if you got your hands on one of these boxes and said "Damn, that thing sounds bad" or something else. I pretty much look at the construction quality and the parts selection and the schematic and go, "Damn, that ought to sound terrible." Then I upgrade the components or build/buy a different circuit and go, "That prolly sounds better." I have a much easier time with gear that's trying NOT to be transparent. I can usually tell when they (or I) succeed. I've been building some transparent gear lately, but I've relied on the folks using it to tell me I got it right. Luckily, I did. But I didn't know for sure until they told me. ulysses |

You don't need to send me the block diagram. I trust you. I suspect that you're correct about the buffers, and that the switching is probably done through solid state components rather than mechanicial contacts. Either could be quite transparent or not. Depends. Like I said, there ARE some PC-mount relays in there, but not as many as there should be. But I know my JH24 does FET switching on the record and reproduce electronics and it sounds good. Idunno if it's *transparent* per se, but the machine as a whole sounds good. I asked the editor of Recording if I could review the C-Control but he didn't reply. Probably still fussing with shortening my 6700 word review of the TASCAM US-122. I hope you get the opportunity to review it for somebody. ulysses |
