Pueblo Audio HJ482
Produktinformationen "Pueblo Audio HJ482"
Pueblo Audio is always looking to provide solutions for its client's constantly changing needs. In an era of instant recalls and homogenous ITB production, busy mixers seek to bring higher caliber summing to their hybrid analog work flow. For this we present our newest product - HJ482 "SideWinder", a truly high-performance summing amp with routings and sonics not found in other products. "SideWinder" is offered in several different configurations so please scroll down for details.
HJ482 • Block Diagram
"SideWinder" consists of four transformer-less, unity gain 8x2 summing banks. Each 8x2 bank may be operated independently and/or internally routed to the last bank (using front panel Bussing Switches) to form 16x2, 24x2, or 32x2 matrixes. In this case, Bank-D acts as a Main Buss for all banks assigned to it. Each individual bank's output remains active to serve as a Sub Group for stems, FX send, parallel processing or whatever you might dream up. The first two channels of each Bank may be assigned as a stereo or mono pair using internal jumpers. This flexibility allows the user to scale SideWinder to a specific project's needs while controlling noise build-up (see diagrams below).
Other features include a Mono Switch for Bank-A which "pans" its mix elements to the center of the stereo field. This follows a -3dB pan law and only affects the bussing to Bank-D. Bank-D is fitted with a -6dB Gain Switch which (when engaged) helps control signal level build-up common with larger mixes. And if you need floating outputs (or enjoy the taste of iron in your mix), Bank-D may be outfitted with bypass-able Output Transformers.

As these specs reveal, SideWinder's attributes are phenomenal. Of note, SideWinder has 2 times lower distortion, 5 times wider bandwidth and 45 times better hum rejection than the next-best product. And, on a per-channel basis, Pueblo Audio delivers this level of performance at the lowest price on the market.
