The Wadia 3 and 5 series disc players are designed in a /technology/modular fashion so they can be upgraded to accommodate new technology.

Multiple Circuit Boards
These disc players feature separate circuit boards for each discrete function: input and output circuitry, digital-to-analog conversion, display/control, and transport servo-controller. This allows specific parts of the unit to be upgraded at the lowest possible cost.

Software Re-Programming
The main program chip in every Wadia design holds the operating software for the major system components. By changing this chip, the unit can be reconfigured in a wide variety of ways. This chip holds the instructions for three circuit sections:

Control Microprocessor
The display, input and output circuitry, and remote functions are controlled by a single microprocessor. Changing the program that controls the microprocessor can modify any of these functions.

Software-Based Digital-Signal Processing
Wadia's patented DigiMaster filtering systems in the Wadia 3 and 5 sesries currently operate at 32 times re-sampling with 24-bit resolution. These systems can easily be upgraded to operate at 96 KHz or 192 KHz, simply by changing the main program chip.

Field-Programmable Gate Arrays
Every Wadia product utilizes these re-programmable devices for input circuitry, clocking, and data handling. Changing the main program chip allows any of this circuitry to be re-configured.

Modular Rear Panel
All three of these units have /technology/modular rear panels so connectors can be added or changed. A format change could easily require new rear panel connectors. Using conventional chassis design, this requires expensive re-machining and modification of the chassis. With Wadia's /technology/modular rear panel, these changes are inexpensive and easy to perform.

A Commitment to Upgrades
Most importantly, Wadia has a proven track record of providing cost-effective upgrades. While other manufacturers offer claims, we offer the most comprehensive history of upgrades in the industry.
