Product Overview
Thank you for purchasing the Model 615808 8-Channel
Audio Mixer with USB I/O by Monoprice®. The 615808 is a
14-input, 8-channel mixer that features a full suite of input
options, including four balanced XLR microphone inputs, four
unbalanced mono 1/4” TS line inputs, two pairs of unbalanced
mono 1/4” TS inputs grouped together for stereo control,
a single USB input/output for connection to a computer, a
3.5mm stereo TRS input, and a pair of RCA inputs. The mixer
can provide +48V Phantom Power to all four XLR mic inputs.
In addition to the USB input/output, this mixer has five
additional outputs. The Phones output is an unbalanced
stereo 1/4” TRS connection, while the Aux Send and the R
and L outputs are all unbalanced mono 1/4” TS connections.
Additionally, there is a pair of RCA outputs. The R and L
outputs are grouped together for stereo control on the mixer.
The 615808 includes the necessary mounting bracket for
properly attaching the mixer to a stand mount.
This User Guide is designed to provide details about how to
set up and use the 615808 using a PC or Mac (see System
