1. INPUT LEVEL CONTROL varies the amount of signal sent to the
master left and right busses through a range of 60 dBm attenuation at full
off to +18 dBm of gain full on.
2. MASTER VOLUME CONTROL determines the amount of signal from
the summing amps that is fed to the left and right outputs. This also has a
gain range of -60 to +18 dBm.
3. HEADPHONE VOLUME CONTROL varies the signal at the
headphone jack. The signal going into the headphone circuit is pre
master fader and independent of the master volume pot.
4. POWER LED indicates that the unit is turned on.
5. HEADPHONE JACK drives stereo headphones with impedances
greater than 30 ohms and is wired with left to tip and right to ring.
6. INPUT JACKS for each of the 16 channels are balanced 1/4“ TRS.
7. MAIN OUT JACKS controlled by the front master volume pot are
balanced 1/4“ TRS and will drive balanced or unbalanced inputs. Each
jack has a separate drive circuit.
8. POWER SWITCH connects AC to the transformer primary and the
front panel LED indicates that the unit is working. Both sides of the AC
line are switched and the main fuse is located on the circuit board inside
the unit.
9. POWER CORD has a standard 15 amp plug for 120 VAC and has no
plug on the Mix 8s 230 VAC model. Black is line, white is neutral and
green is earth.

The U.S. Audio Mix 16 is a line level mixer with 1/4“ tip-ring-sleeve
input jacks. Each input signal is actively balanced through a differential
buffer amp and sent to the channel gain circuit. Each channel has a level
control with a gain range of -60 to +18 dBm, allowing operation with a
wide range of input volume levels. Unity gain is at the 12 o’clock position
for both channel volume and the master volume.
Signals from individual channels are summed together and delivered
to the master gain stages and to the headphone driver circuit. There are
two main output jacks controlled by a single volume pot which has a gain
range of -60 to +18 dBm. Each output jack is balanced (tip is positive)
and driven by a separate circuit. The 60 dBm of attenuation turns off the
audio signal at the main outputs if necessary.
The Mix 16 headphone circuit monitors the summing buss and will
drive stereo headphones with impedances greater than 30 ohms. The
front panel stereo 1/4“ headphone jack has a volume control with a
range of -60 to +18 dB. The signal going into the headphone circuit is a
pre master fader.
Careful layout of the circuit board and a star grounding scheme
ensure no internal ground loops between channels and / or sections of
circuitry. Using low noise components, noise is 81 dB below 0 dB at unity
gain, with one channel up and 76 dB below 0 dB with all channels up at
unity.
The Mix 16 utilizes a dual transformer power supply which is
configured with internal jumpers for 120 VAC 60 Hz or 230 VAC 50 Hz
operation. There is an internal fuse on the hot side of the AC cord, and
the power switch makes and breaks both the hot and neutral legs of the
AC cord.
