85.72.3.244
Hello everybody,
I have read positive things about the effects RTA can have on the performance of a home audio rig. I might be able to pick up a Behringer Ultra Curve DSP8024 for a good price. I have no real experience with pro gear, hence my question might be obvious to many, but I am not quite sure if I can connect the Behringer between my pre- and power amp as I use more than one source (i.e. digital and vinyl). Feedback (also on the sound quality of the unit) will be greatly appreciated.
Many thanks and all the best for 2005.Wolfram
Follow Ups:
You wire the outputs of the pre to the inputs of the 8024, and the outputs of the 8024 to the power amp. You'll need RCA to phone plug cables. Be sure to set the input and output gains according to the instructions for the lowest possible noise without clipping.
Bill,thanks for your input. Sounds kind of simple, provided the instructions are clear enough to follow.
I might be able to pick up a slightly used DSP8024 for a good price, but is there any reason (in terms of sound quality) to wait and invest more for the later unit?

The DSP8024 has fixed max levels of +21 dBu (input) and +16 dBu (output). This is rather hot for consumer gear and can effectively result in a loss of DSP resolution. If you do some searches you'll see that some people have apparently come up against this problem.The DEQ2496 (which replaced the DSP8024) has a switch that chooses between +12 dBu and +24 dBu max levels for the inputs/outputs. If I'm not mistaken, +12 dBu is still on the hot side for consumer gear. However, the extra 9 dB of sensitivity on the inputs (which I believe translates into an extra 9 dB of resolution) could be an advantage worth spending a little more money on. In addition, the DEQ2496 has built-in digital inputs/outputs, so you'd have them if you ever need them down the road. Finally, the DEQ2496 has more powerful processors and higher resolution A/D and D/A, although I don't know if that actually translates into any sonic advantage through the analog inputs/outputs. I'm not sure if they changed the DSP algorithms or increased the resolution or sample rate of the algorithms.
Note that the Behringer web site has downloadable user manuals and spec sheets for both of these products.
I own the DEQ2496, by the way. I used to use it in my home system, but currently it's out of the loop.
I wish either of these had a simple volume knob. You only get 15 dB of volume adjustment. Argh!
I haven't had any problems with my 8024. The main advantage to the newer unit is digital connections, which matter little unless your pre has a digital output.
Actually, you can purchase an SPDIF I/O option (about $30 from Musician's Friend) for the 8024 should you want to keep your signal in the digital domain. I have the DEQ2496, but use it for my live rig. Nice unit. My understanding is that the 8024 cannot simultaneously do RTA and EQ. On the DEQ2496, you can do RTA and have the box serve as a standard comp/limiter, dynamic EQ, graphic EQ, parametric EQ, width controller, and feedback suppressor (not that this would be needed for a HiFi setup, but handy for live). Also, you can set it up to do auto EQ if you purchase their condenser mic ($30-40 street). It can really help to tame a room's acoustic weirdness.cw
Thanks for all the input, it has been appreciated.Wolfram
