TDM Option Cards
he 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
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).
