HELP SECTION
1) MIXER WILL NOT TURN ON
1) MIXER WILL NOT TURN ON
Check the power to the amp. Check for tripped circuit breakers, unplugged extension cords or power-
strip switches that may be turned off. Check the fuse. If a dark brownish color or no wire can be
seen within the glass tube, then replace. The mixer may be perfectly fine but occasionally a fuse
may blow because of high AC voltage surges. After the fuse has been replaced with the proper
Slow Blow value and if the fuse fails again, the mixer will require servicing.

seen within the glass tube, then replace. The mixer may be perfectly fine but occasionally a fuse
may blow because of high AC voltage surges. After the fuse has been replaced with the proper

2) KEEP YOUR MIXER LOOKING NEW
Use caution to avoid spilling liquids or allowing any other foreign matter inside the unit. The top
of the mixer can be wiped from time to time with a dry or slightly damp cloth in order to remove
dust and bring back the new look. A suggestion is to cover the mixer when not in use. This can
be done with a cloth or a small towel to reduce the amount of dust collection on the mixer. Well
cared for equipment is usually friendlier equipment in the long run.

16 CHANNEL OVERVIEW
There are 8 MIC/LINE input channels with XLR and 1/4” LINE inputs and PATCH insert jacks.
There are also 4 STEREO input channels (8 mono) with two 1/4” LINE inputs each. The XLR
channels feature input GAIN controls and provide Phantom power for condenser mics. There
are 3 bands of EQ and 2 post fader effect SENDS on each channel. The master section fea-
tures 2 SENDS and 2 stereo RETURNS along with RCA tape IN’s and OUTs that can be used
as a separate stereo channel with it’s own level control. A master LEFT/RIGHT level control
also feeds a 1/4” stereo headphone jack with its own level control. The stereo LED VU meter-
ing gives you bright,clear visibility of your output levels.

“SHELVING” EQ WITH ACTIVE TONE CIRCUITS
The SM162 incorporates 3 bands of EQ’s per channel that offer smooth tone curves so
your adjustments will sound natural and yet be effective. Depth is added to your bass because
80 Hz is chosen for the LOW frequency EQ controls instead of the usual 100 Hz. The HI EQ
controls are set at 11.5k Hz which is slightly higher than the normal 10k Hz treble controls
giving more top-end clarity. These are “shelving” type controls which cover the complete
frequency band from 80 Hz down to 20 Hz and from 11.5K Hz up to 20k Hz. The MID EQ
controls are a “band pass” type which peak at 2.2k Hz for added presence to your mid range
tones. Because CARVIN uses “active” tone circuits, you are able to boost or cut your tones
without any signal loss in your mixer.

SAVE YOUR INVOICE. It will be required for warranty service if needed in the future.
SHIPMENT SHORTAGE. If you find items missing, they may have been shipped sepa-
rately. Please allow several days for the rest of your order to arrive before inquiring.

INTERNAL SIGNAL ROUTING WITH NO RF
Your balanced mic or instrument plugs directly into the high quality XLR Nortrics con-
nectors (used in hundred thousand dollar consoles) and is then routed into the differen-
tial circuits for excellent hum and noise cancellation. As your signal continues within the
console, a double-sided printed circuit board (FR-4 fire rated) carefully guards the circuit
traces with a copper shield running over the traces. This eliminates RF interference and
reduces crosstalk substantially. The printed circuit board has 931 plated-through holes
which means that every component is soldered securely in three places (bottom, in hole
and top). This offers unsurpassed component security while reducing circuit resistance
for pure dynamic sound which is unaffected by poor solder connections.

MORE HEADROOM
Headroom is very important when designing a mixer—especially for recording. Lack of head-
room will cause your sound to become distorted and muddy. This can happen when you turn
the volume too high, if the input signal is too hot or if excess bass or treble is added. With most
mixers, you have to reduce the input gain to fight headroom problems, but this just increases
noise. That’s why we have taken great care in the SM162 to make sure that each gain stage is
properly designed and balanced with more headroom along the entire audio path. There is no
headroom “bottle necking” at the summing stages, ensuring clean, pure audio throughout.

MICRO TOROID SUPPLY
You won’t find the precision Micro Toroid Supply in any mixer except the SM162 and other
CARVIN high-end products. Pure DC is generated from this power supply which features
precision 7815 and 7915 voltage regulators which hold voltage tolerances to within .001%.
Now you can go anywhere and never have to worry about the mixer giving you the exact
output and sound you are accustomed to. Another big feature in this power supply is the
precision wound Toroid transformer (not available from our competition) that gives
unsurpassed rejection of noise and hum. You can place the SM162 over sensitive gear
and not be concerned about injecting hum or noise into it like a standard transformer could.
CARVIN has spared no expense to achieve studio quality performance.

PROFESSIONAL HEADPHONES
The SM162 is designed to be used with professional headphones. The impedance of the head-
phone set should be between 40 and 100 ohms with a sensitivity of at least or high than 100
dBm at 1k Hz with 1mv input. 8 ohm or 500 ohm and higher headsets are not recommended.
