MyMONITOR Personal
Monitor Mixer
Personal mixer/
headphone
amplifier
accepts stereo
line level input,
mixes it with a
balanced mic input,
and provides stereo
headphone output.
Parallel “Thru Mic”
output allows easy insertion into existing PA
system. This is ideal for studio or stage use,
where a performer desires to hear his microphone,
combined with the overall mix, through headphones.
Independent level controls for the line and mic in
allow easy mix adjustment. Thru Mic output will
pass phantom power, and is unaffected by mix
settings. Specifications: •Line input:
1

(TRS) •Mic input: XLR female •Mic output: XLR
male •Headphone output (2):
1
⁄4" stereo •Max
input level: -20dB (mic), 40dB (line level) •Output

Balanced/Unbalanced Line Level Convertor
Two-way, stereo convertor provides total flexibility
when interfacing consumer and professional audio
equipment. Perfect when using tape decks, MP3
players, computer sound cards with mixing consoles,
sound processors, professional preamplifiers and
amplifiers. Two stereo channels simultaneously match
balanced to unbalanced, and unbalanced to balanced
equipment. Stereo Channel 1: L/R balanced female
XLR inputs to L/R unbalanced RCA female outputs.
Stereo Channel 2: L/R unbalanced RCA female
inputs to L/R balanced male XLR outputs. Each
stereo channel has its own level adjustment to
compensate for line level differences between pro and
consumer gear. Specifications: •Max output gain:
+18dB balanced, +12dB unbalanced •Max input
level: +22dB balanced and unbalanced •Power
