DBX 503

Audio Proz Inv #: 27352

Modified 3 band compressor/expander with vairiable control. Ground, power supply, and input gain modifications. Nice controls. Excellent unit.

The 503 is simply the rack mount version of the original 3bx expander design with 2 variations of circuits. 1 version 3bx used all discreet circuit parts and actually can sound a little tube like with some harmonic "thickness" due to the VCA design. This is a very rare version. The later second version used a custom made dbx IC used in most vintage products. Both 3BX are known to sound robust in comparison to modern 3BX XDS which can sound a little forward and slightly bright.

Re: International Shipping: We ship internationally often and have yet to encounter a problem or complaint. We are very careful to test the equipment before it’s packed and then to double box the machine with added protection when needed for front panels, etc. We are not amateurs or an ebay store; we know these machines very well and know what it takes to get them to you safely. We use USPS priority internationally which seems to be the cheapest. If you prefer another carrier (you should know who delivers to your area reliably) please let us know. Also please be aware of any tariffs that you may be responsible for upon pick up on your end. International shipping may be expensive but we will make sure it is not a headache on top of the cost. PLEASE NOTE THAT SHIPPING INTERNATIONALLY WILL BE A MINIMUM OF $16 EVEN FOR SMALL PARTS.
