What Accessories, Parts, and Upgrades Are Available for RLC Controllers?

Audio Test Solutions, Inc. lists accessories, parts, radio/IO cards, and upgrade boards and packages for its RLC controller line on rlccontrollers.com. The catalog groups these into four areas: RLC Controller Accessories, RLC-Controller Parts, RLC-3 Radio Cards/IO Cards, and two upgrade options — RLC-CLUB DELUXE 2 (a 5-port upgrade board and package) and RLC-CLUB DELUXE (a 1-port upgrade board and package). If you already own an RLC controller and want to expand ports, replace a card, or move up to a more advanced controller, these are the categories to check first.

Accessories and parts

The site separates two categories that are easy to confuse:

• RLC Controller Accessories — items that support or complete a controller installation.
• RLC-Controller Parts — components for building or maintaining controllers.

Both are listed as distinct product categories under PRODUCT OFFERINGS, so if you are searching for a specific item, check both before assuming it is unavailable.

Radio and IO cards

RLC-3 Radio Cards/IO Cards is its own category. These are the cards used with RLC-3 controllers for radio and input/output functions. Because they are listed separately from general parts, treat them as a distinct purchase path — useful when you need to add or replace radio/IO capability rather than a mechanical or accessory item.

Upgrade boards and packages

Two upgrade paths are listed:

These are described as upgrade boards and packages, meaning the upgrade is supplied as a board plus the associated package rather than as a standalone board. The naming also tells you the target: both are DELUXE-class upgrades, with the DELUXE 2 covering 5 ports and the DELUXE covering 1 port.

Stock availability

Audio Test Solutions states that RLC Repeaters and Linking Controllers are actively stocked, that controllers are commercial quality and American manufactured, and that it works to maintain a consistent supply of parts for building its radio controllers. The site also notes that several previously discontinued products have been brought back to active stock.

That last point matters when you are sourcing a part for an older controller: a component you assumed was discontinued may now be listed as active stock. Check the current listing rather than relying on older availability information.

How to choose

• Adding ports to an existing controller: compare the 5-port RLC-CLUB DELUXE 2 against the 1-port RLC-CLUB DELUXE and pick based on how many ports you actually need.
• Replacing radio or IO functionality: go to RLC-3 Radio Cards/IO Cards.
• General repair or build: check RLC-Controller Parts, and check RLC Controller Accessories for supporting items.
• Buying a controller rather than upgrading one: the main product line is RLC-1 (2-port basic), RLC-4 (4-port basic), and RLC-CLUB (1-port advanced).

For current pricing, exact package contents, and compatibility between a specific upgrade and your existing controller, confirm with Audio Test Solutions directly — the site's product listings do not state prices or per-item compatibility details.
