This Module was designed for my private usage, to install it in some Arp Clones like the TTSH or in old vintage gear.
the 6.3mm Connection is optional, the Signal output is at the TRS 3pol MTA header available for XLR Connections too.
the Circuit is Phantom power protected.
the benifits are symmetricial outputs with an bigger headroom and for situations with long cables or problems with EMV..
for TTSH Users: the TTSH isn´t a true Stereo Device, one of this PCB is fine for your TTSH.
