Who is GRS Pro Audio Systems ?   

GRS Pro Audio is part of the GRS Systems, LLC group... 

GRS Systems, LLC is a wholesale distributor and manufacturer of digital audio & graphic equipment, software and audio/video training tools. The GRS Pro Audio Division was born out of this entity, being the production end of our software CD ROM's and other products that GRS Systems manufactures. 

     

GRS Pro Audio operates a full 'state of the art' production studio and manufacturing plant. We build and maintain professional audio gear for our own use, for commercial studios and for resale. In 2004, GRS Pro Audio expanded its offerings to include specific parts for the growing DIY group of pro audio equipment builders.

    

GRS Pro Audio's founders have been installing, maintaining. modifying and even redesigning audio consoles, tape machines and most other pro audio equipment since 1969.

    

Our 'off the shelf' online product offerings are limited, by design... but ever growing. We will be adding a limited stock of high quality audio parts to our line in incremental steps. Other new offerings include the GRS line of custom Power Supply systems for upgrading recording consoles and other equipment. Also added are select Hammond power transformers, custom designed racks and cabinets with engraved front panels and some unique specialty parts.

   

GRS Pro Audio continues to offer NEW PSU's and upgraded and rebuilt Power Supplies for recording consoles, pre-amps and tape machines. All of our custom PSU's are 'hand built to order' in our shop and carry a full 5 Year Warranty!

   

Please let us know if there is a service we can provide you or a hard to find component that we can help you find!

    

GRS PRO AUDIO HISTORY


     

   

3M M79 RESTORATION, PARTS & SERVICE

    

        

    

M79 Master Recorders from 'The Record Plant' Mobile Truck with upgraded electronics, new heads, new pinch rollers and all new bearings with rebuilt motors and a new maple cabinet (left). Setup for 14" reels.

     

   

      

   

We are expert at rebuilding and modding the M79 Power Supplies. We upgrade the PSU with higher reliability current pass transistors and with better quality / low ESR / hi-temp computer grade filter caps. We also upgrade the bridge rectifiers to specialty units that handle higher currents and produce less line noise.

We service and sell refurbished Sony APR-24's. This one is being serviced and fully re-capped. Heads are being re-lapped and the power supply is being rebuilt. The transport is being upgraded with new precision bearings and new rollers. The tape path will be fully aligned and all marginal parts will be replaced or rebuilt.
