There's 4 phono (RCA) sockets - the white and red ones, giving you
conventional RCA/phono connections eg to an amplifier. Those
will be 'unbalanced' connections ie each has a signal and a screen.
Each of the four outputs is also provided on a 1/4-inch jack socket (the
four black holes you can see). It's just a different type of connector
providing the same output signal, possibly 'balanced' on a TRS (tip,
ring, sleeve) jack...
The specifications listed at
do not make it clear whether the four output 1/4" jacks are TRS or not, though it does
say that the 'main outputs' (presumaby a stereo monitor mix) are available on balanced
TRS jacks as well as balanced XLRs.
Ah... the "Quick Start Guide" available on:
has a more detailed list of what each socket is - those 4 'black holes' ARE 'TLS' jacks, ie balanced -
that is there's three connections for each channel - the +ve half of a waveform, the -ve half, & the
screen. So if you were connecting the four channel outputs to domestic audio/hifi equipment you'd
use the RCA phono jacks (the white and red ones) and if you were connecting it to studio equipment
that could handle/expected balanced connections you'd use the TLS jacks (black sockets).
Jeremy Nicoll - my opinions are my own.
