Schaack Audio Technologies Quad

Strengths:

- The system probably scratch the cheapest on the market (€ 89 + VAT and comes with 4 vinyls)
- Up to 4 turntables can be connected to the computer
- Any ASIO soundcard can be used (you just have a phono preamp, but cheap c (+ / - € 25))
- Very good response from scratching, equivalent to more expensive products in the field (eg Serato)
- Automatic adjustment of the tempo if desired -> you can easily mix up to four MP3, which would otherwise be impossible
- Good EQ, filters, FX
- MIDI control of almost all parameters
- Good browsers
Usage:

I use it with my M-Audio sound card connected to two Technics Delta1010LT SL1200MK2. The response time is very short, we can not tell the difference between real and vinyl scratching with Quad. The program has also been tested by JFB, the DMC scratch champion in 2007, and was of the same opinion (tested in magazine DJ Mag).
Config:

- Athlon 2000 with sound card M-Audio Delta 1010LT
- 2 Technics turntables SL1210MK2

GETTING STARTED

- Installation is done in 10 seconds
- There was no incompatibility with my PC, but may need to do with other config. Anyway home I not had a single problem in four months.
- The general configuration is very easy, but must of course read the manual
- The manual is in English only, but c fairly well explained.

SUITABILITY/PERFORMANCE

My config is ultra-stable, CPU usage varies between 5% and 40%, depending on the number of turning all MP3 and of course the number of effects used. I have an Athlon 2000 with a sound card M-Audio Delta1010LT

OVERALL OPINION

I use Quad for 4 months and I am more than satisfied with the performance and the number of functions within this program. I have tried other software like Serato and Final Scratch and I must say at the price of € 89, Quad is unbeatable. The response of scratching movements is very fast, there is no difference between the scratch and scratch MP3 Quad with the real vinyl. The effects are nickel, the only thing that bothers me is that you can not cut the different parts of the program, but it's a detail.
