TDM Option Cards
The TDM 24CX series crossovers have internal connectors for option cards. A variety of different option cards is available from TDM. Plugging a card into the connector inserts the circuitry on the card between a crossover section output and the output of the unit. The most common card to use for this application is the high-pass filter card. This card is used on the low- frequency section of the crossover to remove subsonic frequencies from the output. This helps remove stage rumble and wind noise, and also helps prevent speaker damage. Another popular option is the parametric equalizer card. Each card has two fully parametric equalizer bands that can be inserted on any crossover output. The cards are installed internally, so once they are set up, they are under the cover and their settings cannot easily be changed. This is an advantage in situations where you don’t want the settings changed, but it is an obvious disadvantage in cases where the settings will change often. In these situations, an external filter or equalizer is recommended. For information about all of the available option cards, contact your vendor or
call TDM (see Contacting TDM).
