Would you build this DIY project?
Hi folks:
Let me launch a trial balloon here. Is this a DIY project that appeals to you? It's a microphone preamp, solid state, transformer in (Jensen), transformerless balanced +4dBu out with a separate -10dBV unbalanced out. IC based, up to 8 channels in a 2U case, plus separate power pack. Phantom on all channels, 100Hz rolloff selectable on all channels, otherwise no EQ. Designed to be comparable to the Sytek in price, performance and feature set, but with transformer-coupled inputs. All parts obtainable (to North Americans, at any rate) from Digi-Key and Allied Electronics, except for the transformers, which come directly from Jensen. On-card regulation. Like the Sytek, there are some optional choices in what ICs you use. Approximate costs are as follows. These include everything except the cases, which are up to you. At the moment I'm assuming the PC boards would cost $25.00 / ea.; that's the biggest unknown in the equation. I can't really fill that in until I design the boards, and I'm not gonna do that until I find out whether anybody's interested. (Also, of course, price of the boards will vary depending on how many I order.) There are options which will raise the price, and some that will lower it, but this is the basic design. Each input channel: $220.00 Power Supply: $120.00 So a 4-channel unit would cost almost exactly $1k, not counting boxes. An 8-channel would be $1880, ditto. I'd make my slice selling the PC boards and writing it up for the magazines. Any interest? Peace, Paul |
