This 2m cable allows recording of DC coupled external equipment by bypassing the Lynx-8 amplifiers and sending the signal directly to the recording PC. Eight female BNC connections are provided for external input. A female MDR-30 is connected to the JAMP connector from the recording PC instead of the analog output of the Lynx-8. It can also be used in conjunction with the L8-BNC to selectively insert external signals with signals from a Lynx-8 amplifier.
