The Japanese DJ mixing company Alpha Recording System presents the six-channel noble rotary DJ mixer with the ARS Model 9900PRO and the Model 9900STD. The small boutique manufacturer from Tokyo is known for very high-quality DJ equipment, with which so far only a few lucky DJs were ever allowed to play.
The new six-channel rotary mixers Model 9900 PRO and Model 9900 STD will probably not change that, because the parts not only offer absolute top quality but unfortunately also cost a lot of money.
Like the four-channel ARS Model 900, the Big Brothers have a Rotary Volume knob, a 3-band EQ (12 dB cut/boost), a pre-listen path, and a post-fader send path with master return per channel, a master effect insert, as well as separate outputs for the master (in this case called “House”) and the monitor output (“Booth”). Since the ARS Model 9000 is a full-isolator mixer, with isolators also in the channels, the 9900 has opted for a 3-band EQ with 12 dB cut/boost.
The coveted ARS 3-band isolator towers over the channels with 18 dB boost and infinite cut. As is common with Alpha Recording System, the Model 9900 mixers also have a large external power supply to prevent interference. There is no power switch to prevent accidental power on and off. All components used are of very high quality, so all potentiometers from ALPS and the classic-looking potentiometers and controls are all made from Japanese production.
In addition, the noble “Music Mixer” (so the modestly printed name) has two precisely illuminated VU meters from Sifam and in the “PRO” version on noble-looking side parts made of wood. A total of three turntables and nine line sources can be connected and switched backwards. Another difference between the PRO and the STD version: thanks to the particularly high-quality XLR output transformers cable transmission lengths of up to 300 meters are to be possible, whereby the PRO version is also suitable for large festivals.
While the smaller four-channel model 9000 tabletop, due to its compact dimensions of 28 x 24 x 9 cm, still passes as a travel mixer that can be transported in the record pocket, the generously sized big brother ARS Model 9900 is intended primarily as an installation mixer for clubs speak next to the rich dimensions of 46 x 28 x 10 cm and all necessary connections also the called price of approx. £4100 for the standard version and over £4500 for the pro version.
Basically, the Model 9900 is based on similar technology as the high-quality components of Alpha Recording System. In this Ministry Of Sound shootout video, an ARS setup consisting of a Model 4100 mixer with an additional Model 3500 isolator and Model 5000 five-band equalizer will compete against Rotary mixers from Allen & Heath and Urei.
