IDS Equalizer 






The IDS-25 Loudspeaker Equalizer is designed specifically to complement the IDS-25 loudspeaker. Together, the speaker and equalizer make the complete IDS-25 system. The contour is unique for the IDS drivers, including their arrangement in a long column.

The circuit contains high-speed op-amps, film capacitors and metal film resistors. A mode switch is included to allow the user to leave the equalizer connected to the system but electrically flat in response, in case a different speaker is being used.

Response is electrically flat at the OUT position.

The mode selector must be at the IN position when the IDS-25 system is used.

Both balanced and unbalanced connectors provided for inputs and outputs.
A line voltage switch is also provided for 120V and 240V. The AC 3-wire line cord is removable.
