The jack near V2 is for the eq footswitch. The other jack is the pre amp out - power amp in jack.

From the Mark llc manual:
A Pre Amp Out-Pwr Amp In jack is located on the bottom of the chassis and provides access to the junction of the preamp and the output power amp. With it, another Boogie can be linked up (Slave Out of the first amp to Pwr Amp In of the second), or it can allow you to use the Boogie as a preamp only.

Also located beneath the chassis is a stereo socket for the optional Dual Footswitch. This will be wired to activate, when applicable, the Graphic EQ and Reverb. When an amplifier is built with only Reverb or Graphic, a mono 1⁄4” guitar jack is mounted for use with our Single Footswitch and Cable Set
