Read these instructions.
Keep these instructions.
Heed all warnings.
Follow all instructions.
Do not use this apparatus near water.
Clean only with dry cloth.
Do not block any ventilation openings. Install in accordance
with the manufacturer’s instructions.
8. Do not install near any heat sources such as radiators, heat
registers, stoves, or other apparatus (including amplifiers)
that produce heat.
9. Do not defeat the safety purpose of the polarized or
grounding-type plug. A polarized plug has two blades with
one wider than the other. A grounding type plug has two
blades and a third grounding prong. The wide blade or the
third prong are provided for your safety. If the provided
plug does not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.
10. Protect the power cord from being walked on or pinched
particularly at plugs, convenience receptacles, and the point
where they exit from the apparatus.
11. Only use attachments/accessories specified by the
manufacturer.
12. Use only with the cart, stand, tripod, bracket, or table
specified by the manufacturer, or sold with the
apparatus. When a cart is used, use caution when
moving the cart/apparatus combination to avoid
injury from tip-over.
13. Unplug this apparatus during lightning storms or
when unused for long periods of time.
14. Refer all servicing to qualified service personnel. Servicing
is required when the apparatus has been damaged in any
way, such as power-supply cord or plug is damaged, liquid
has been spilled or objects have fallen into the apparatus,
the apparatus has been exposed to rain or moisture, does
not operate normally, or has been dropped.
15. Exposure to extremely high noise levels may cause
permanent hearing loss. Individuals vary considerably in
susceptibility to noise-induced hearing loss, but nearly
everyone will lose some hearing if exposed to sufficiently
intense noise for a period of time. The U.S. Government’s
Occupational Safety and Health Administration (OSHA) has
specified the permissible noise level exposures shown in the
following chart.
According to OSHA, any exposure in excess of these
permissible limits could result in some hearing loss. To
ensure against potentially dangerous exposure to high
sound pressure levels, it is recommended that all persons
exposed to equipment capable of producing high sound
pressure levels use hearing protectors while the equipment
is in operation. Ear plugs or protectors in the ear canals or
over the ears must be worn when operating the equipment
in order to prevent permanent hearing loss if exposure is in
excess of the limits set forth here.

What me, read a manual?
Before you begin, please make sure that you read the Safety Instructions on page 2 and Getting Started on
page 4. One will help you keep safe, and the other will get you started using your new TAPCO® Blend 16 mixer.
Your new mixer is designed to be set up quickly and to operate easily. We know it’s often seen as a sign of
weakness to read a manual, along with asking for directions when lost, or admitting that it was you who painted
the dog purple and green when you were eight, ..er....but maybe you can read the rest of the manual when
nobody is looking.
Please keep your receipt in a safe sock drawer, and write your product information here for future reference
(i.e., insurance claims, tech support, return authorization, etc.):

Getting Started
The following steps will help you set up your mixer, and get the levels and adjustments just
right. Please follow the instructions in the order they are presented, rather like following the
instructions for mixing a lemon bundt cake, or running a nuclear power station, for example.
ZERO THE CONSOLE:
1. Turn everything off, including the mixer’s rear panel
POWER switch and PHANTOM POWER switch.
2. Turn down all channel strip GAIN, AUX SEND 1, and
AUX SEND 2 knobs.
3. Center the channel strip EQ and PAN knobs.
4. Turn down the MASTER FX RETURNs and AUX SENDs,
CONTROL ROOM, PHONES and other level knobs.
5. Move all FADERs fully down.
6. Center the Stereo Graphic EQ sliders.
7. Make sure all push buttons are in the up position.
CONNECTIONS:
1. Connect speakers to your amplifier’s outputs
(unless you have powered speakers with built-in
amplifiers).
2. Plug all the sound system components into suitable
AC outlets, properly grounded and capable of
delivering correct voltage and adequate current.
3. Make connections from your mixer’s MAIN MIX
outputs to your amplification system’s line inputs.
4. Connect your microphones and instruments to the
mixer: Connect microphones to the mono channel
MIC jacks. (For condenser microphones, you may
have to turn on the PHANTOM POWER switch,
so read your Mic’s documentation.) Connect
instruments directly to the INST 1/4" inputs, and linelevel sources (synthesizers, guitar effects, preamps)
to the stereo channel LINE IN 1/4" inputs.
5. Connect the USB port to an open USB port on
your computer, using the cable provided. Two
channels of audio can be sent to your computer
for recording, and two channels can return onto
the main mix from your Tracktion or other DAW
software. See “USB and the Blend 16” on page
19, for more details about using the mixer with a
computer.
6. Zero the console, as described above.
7. Turn on your components’ power switches, leaving
the amplifier (or powered speakers) until last.
8. Now you are ready to set the levels.
SET THE LEVELS:
1. You can set the levels without hearing the sounds,
but if you prefer, connect a set of headphones to
the PHONES jack.
2. Choose one of the microphones or instruments
connected to the mono MIC or INST inputs.
3. Press that channel’s SOLO switch in.
4. Have a wandering musician make some noise. If
it’s a microphone connected to that channel, sing
sweetly at the normal volume. If it’s a synthesizer,
play it at its normal output level.
5. While making music, turn up that channel’s GAIN
knob until the nearby LEVEL SET LED starts blinking.
6. With SOLO pushed in, you should see the meters
grooving along with the music (and the RUDE
SOLO light blinking).
7. If the GAIN is set correctly, the sound level should
be nicely hovering around the 0 dB LEDs. If the
average seems to be higher, turn down the GAIN.
If it seems too low, turn it up.
8. Carefully turn up the PHONES knob and listen.
9. If necessary, apply channel EQ changes.
10.Turn down the PHONES knob.
11.Release the SOLO switch for that channel.
12. Repeat steps 2 through 11 for all other active
channels, until all the GAINs are set correctly. You
can repeat this procedure later, if needed. Once
you get going, you will be surprised how quickly
you can set up all the levels.
MAKING THE MIX:
1. Make sure all levels are set correctly, as described in
the previous section.
2. Set the SOURCE SELECT switch to MAIN MIX, so your
meters (and headphones) will receive the main mix.
3. Add an active channel to the main mix by pressing
the L-R switch near the bottom of that channel strip.
4. Turn that channel’s FADER up to the U mark (0 dB).
5. Carefully turn up the MAIN MIX FADER and listen to
the glorious sounds in your main speakers.
6. Repeat steps 3 and 4 until all active channels are
added to the main mix. As you add each instrument,
shout out its name loudly like this: “Introducing BillyBob Beauregarde-Baker on Big Bass Banjo.”
7. Carefully adjust the channel FADERs and the Graphic
EQ to suit the main mix to your delicate audio senses.
8. To use the internal processor, adjust each channel’s
AUX SEND 2 FX control to send signals to the
processor. Adjust the FX INPUT LEVEL knob so the
internal processor is not overloaded (FX OL LED off).
Add the processed signal to the main mix using the
FX RETURN TO MAIN MIX knob.
9. Now that you have a rough mix going, you
may need to readjust the MAIN MIX FADER to a
comfortable listening level. The meters should
indicate by lighting most of the green LEDs when
music is playing, and occasionally light the yellow.
• Only plug your amplifier’s speaker-level outputs
into speakers, never to the mixer.
• Never use guitar cables to connect amplifiers to
speakers.
• Before making connections to an external
amplifier, or reconfiguring an amp’s routing, turn
the amp’s level (gain) controls down, turn the
power off, make the changes, turn the power
back on, and then turn the level controls back up.
10.Depending on how much time you have, keep
tweaking. Walk the room to see how it sounds
away from your mixer. Keep tweaking FADERS and
EQ as needed. Watch out for any OL overload
LEDS blinking, as the band plays on.
• When you shut down your equipment, turn off any
external amplifiers first. When powering up, turn on
the amplifiers last.
A FEW PRECAUTIONS:
Never listen to loud music for prolonged
periods. Please see the Safety Instructions
on page 2 for information on hearing
protection.

Introduction
Thank you for choosing a TAPCO Blend 16 mixer, with 16 channels of pure goodness. It has even more
channels than an 8 channel mixer, and not quite as many as most 20 channel mixers.
The TAPCO family of mixers hails back to the days of TAPCO Corporation, Greg Mackie’s first company.
TAPCO revolutionized the audio industry back in 1969 with the very first 6-channel mixer designed for keyboards
and rock ‘N’ roll PA. The first TAPCO mixer, although primitive by today’s standards, was truly innovative for its
time. It had the headroom to handle screaming singers, was priced for the pocketbook of starving psychedelic
musical neophytes, and durable enough to withstand mammoth levels of wear and tear on the road, and at
now-legendary concerts.
This compact mixer is perfect for small to medium-sized live sound reinforcement applications, keyboards
and synths, video, and project studio applications.
The USB port on the Blend 16 makes it easy to get audio from your mixer to your computer-based DAW. And
just in case you don’t have the software, we’ve included a CD-ROM with the full version of Tracktion, our easyto-use multitrack recording and sequencing software (for the PC or Mac). Refer to the installation instructions on
the Blend 16 software CD to install Tracktion on your computer.
Here’s a quick glance at all the features packed into this mixer:

Mono channels 1 to 8 allow adjustment
of EQ, Pan, and Level for mono signals. The
output from each channel strip can be
assigned to the main mix and subgroups.
Auxiliary signals can be tapped off and
sent to Aux bus 1 (monitors) and Aux bus 2
(effects).
The U symbol on most of the controls
stands for “unity gain,” meaning there
is no change in signal level. Once you
have adjusted the GAIN control correctly,
you can set every control at U, and your
signals will travel through the mixer at
optimal levels.
Use the XLR inputs, or the 1/4" inputs,
but not both on the same channel at the
same time. Dedicate each mono channel
to only one input at a time.
See Appendix B for more information on
XLR, 1/4" TRS, and TS connectors.
1. MICROPHONE INPUTS
Channels 1 to 8 each have a real butch
and rugged, low-noise, phantom-powered
microphone preamplifier, providing
crystal-clear amplification. Their balanced
circuitry rejects all manner of extraneous
interference. Professional condenser,
dynamic, and ribbon mics all sound
excellent through these XLR inputs.
You can plug in almost any kind of
balanced mic that has a standard XLRtype male mic connector. See Appendix B
for more information on XLR connectors.
These XLR inputs can provide +48 VDC
phantom powering on pins 2 and 3. This
can be turned on and off using the rear
panel PHANTOM POWER (54) switch.
Caution: DO NOT connect
a line-level device to an
XLR input with the phantom
power switched on. This could
damage the device. Use the
stereo channel LINE (19) jacks instead.
Do not use phantom power with tube or
ribbon microphones, as this may cause
damage.
2. INST INPUTS
The INST (instrument) inputs accept 1/4"
TRS balanced and TS unbalanced plugs.
These high-impedance inputs are
suitable for the direct connection of
instruments such as guitars, without the
need for a direct box or guitar preamp.
3. INSERTS
These 1/4" TRS inputs allow you to insert external
processing equipment into the channel signal path
(after the LOW CUT (6) switch and before the EQ).
Using a special Insert plug, the mono signal can
be sent out to a processor, and the processed signal
returned, all on the same plug (see Appendix B).
Nice.
4. GAIN CONTROL
If you haven’t already, please read “SET THE
LEVELS” on page 4.
This control allows you to adjust the input sensitivity
of the MIC (1) and INST (2) inputs. This allows signals
from the outside world to be adjusted to the correct
level, not too strong to cause distortion and not too
weak to be lost in noise.
5. INPUT LEVEL SET LED
This handy LED lets you know that the signals
going into the mixer are adjusted correctly.
After you connect a microphone or line-level
component to the mixer, do a sound test and
adjust the GAIN (4) control until this LED flickers just
occasionally. If it glows constantly, turn the GAIN (4)
down. If the LED is doing almost nothing, turn it up.
6. LOW CUT FILTER SWITCH
This inserts a low cut filter into the signal path,
reducing the bass level (below 75 Hz, at 12 dB per
octave, if specs are your thing). This occurs after
the GAIN (4) level, but before the INSERT (3), EQ
(7-10) and AUX (11-12) sections. Use this to cut
down the low bass from things like stage rumble,
mumble, bumble, and any low sounds that seem to
come from two apartments down. We recommend
you use this on all channels unless they have low
frequency signals such as kick drums and bass
guitars.
EQUALIZATION
Each EQ control provides up to +15 dB of boost,
and –15 dB of cut, with no change to the signal in
the center position (0 dB).
Although you can bring a sound to life with
proper EQ, you can also mess things up. If you max
the EQs on every channel, you’ll get mix mush, not
to mention driving your mix levels near or beyond
clipping. So equalize subtly; use cut as well as boost.
7. HIGH EQ
Turn this clockwise to boost the level of all
frequencies above 12 kHz. Turn it counter-clockwise
to cut the levels.
Use this wisely to add sizzle to cymbals or an
overall sense of transparency or edge to keyboards,
vocals, guitar, and bacon frying. Turn it down a little
to reduce sibilance or hide tape hiss.

8. MID FREQ EQ
This adjusts the frequency of the MID EQ
(9) control from 100 Hz to 8 kHz. This gives
you great flexibility in shaping your sound.
Listen carefully for its effect.

Frequencies of 80 Hz and below
represent the punch in bass drums, bass
guitar, and wild Tuba raves.

This control taps the channel’s signal
before the channel FADER (17), and sends
it to the AUX 1 bus. The control ranges from
infinity (off) to +15 dB.
AUX SEND 1 MON is normally used to
send a separate mono mix to your stage
monitors, via the AUX SEND 1 (22) output
jack. Use the MASTER AUX SEND 1 (43)
knob to control the overall level.
Most of the channel controls will affect
the output to your stage monitors, except
for PAN (13), AUX SEND 2 FX (12) and the
channel FADER (17).
12. AUX SEND 2 FX
This control taps the channel’s signal
after the channel FADER (17), and sends it
to the AUX 2 bus. The control ranges from
infinity (off) to +15 dB.
The AUX SEND 2 FX bus feeds the
internal effects circuits, and optionally,
it can feed external effects devices (via
the AUX SEND 2 (23) output jack). Use the
MASTER AUX SEND 2 (44) to control the
overall effects level.
Most of the channel controls will affect
the output to the internal (or external)
processor, except for PAN (13) and AUX
SEND 1 MON (11).
13.PAN
This adjusts how much of the channel signal plays
in the left side of the main mix and subgroups, and
how much plays in the right. Careful use of PAN
allows you to set up a nice stereo image in the left
and right.
For the mono channels, if PAN is in the center
position, the mono signal appears equally in both
the left and right of the main mix. If the control is set
left, more of the signal appears in the left side. If the
control is set right, more of the signal appears in the
right side of the mix.
For stereo sources, where you are using two mono
channels, the standard convention is to plug in the
left signals into the odd-numbered channels, and
the right signals into even-numbered channels. Then
you can pan the odd channels hard left, and the
even channels hard right.
14. MUTE
Press this switch to prevent that channel’s signals
from reaching the main mix, aux, or subgroups.
(Soloed channels can still be heard in the control
room and phones.)
15. OL (OVERLOAD) LED
This will light when the channel’s signal is close to
clipping.
If this comes on, turn down the channel’s GAIN (4)
knob, or your EQ (7-10) settings. (The channel FADER
(17) or PAN (13) will have no effect.)
16. 1-2, 3-4, and L-R SWITCHES
These three switches are used to assign the
channel’s signal to the subgroups 1-2 and 3-4, and
the main mix L and R buses.
For example, if you want channel 1 to go to
the subgroup 1-2, and subgroup 3-4, press the 1-2
and 3-4 switches of channel 1. (The channel 1 PAN
(13) knob will pan the channel’s signal between
subgroup 1 and 2, and between subgroup 3 and 4.)
If you want channel 2 to appear on the main mix,
press L-R on channel 2.
17. FADER
This is the master level control for the channel’s
signal. Subtle adjustment of the channel faders is the
key to a finely-tuned mix.
Typically (providing the GAIN (4) is set correctly),
this will be somewhere near the 0 dB (U) position.
If you have the fader set all the way up, it’s usually
a sign that your GAIN (4) is set too low. If the fader is
set way down, your GAIN may be too high.
18. SOLO
Pressing this switch in will send the channel’s
signal to the control room and headphones output
for monitoring. The RUDE SOLO (47) light will flash
on and off as long as any of the solo switches are
engaged.

For an example, suppose your
band is performing on stage, and
you hear something unusual (well,
more unusual than normal). Without
interrupting their performance, you
can Solo each channel in turn, and
listen in the headphones until you
identify the problem channel or
band member. The Solo signal is not
affected by that channel’s MUTE (14),
or FADER (17). The channel signals to
the Aux, main mix and subgroups are
not affected.

The following details show the
differences from the Mono channels:
There are no microphone inputs,
inserts, or low cut filters, and the Mid
EQ frequency is fixed at 2.5 kHz.
The 1/4” inputs are Line-Level, not
instrument level.
As AUX 1 and 2 buses are mono,
the stereo signals are summed before
reaching the AUX SEND (11,12) knobs.
SOLO (18) sends a sum of both
channels to the control room and
headphones.
GAIN (4), EQ (7-10), and MUTE (14),
and the channel FADERs (17) operate
equally on both left and right signals.
PAN (13) works rather like the
balance control on a home stereo,
adjusting the left and right balance
onto the main mix or subgroups.
19. LINE INPUTS
These inputs accept 1/4" TRS
balanced and TS unbalanced plugs
from any line-level instrument, effects
device, or tape player. They can be
driven by virtually any line-level signal.
Guitars and other instrument-level
sources should not be connected
directly to these inputs. Use the INST
(2) inputs of channel 1 to 8, or use a
preamp to give a line-level output,
and connect that to these inputs.
Mono sources should be
connected to the left input only. The
left signal will then be split equally to
the left and right. You can use the
PAN (13) control to change the left/
right balance of the main mix and
subgroups.
Stereo sources should be
connected to both left and right
inputs, where they will pass through
the channel strip separated. The
standard convention is to plug in the
left signals into the odd-numbered
channels, and the right signals into
even-numbered channels.
20. LINE/PHONO switch
(channels 13 and 14 only)
In the up position, channel 13 and
14 accept line-level signals.
In the down position, these
two inputs accept phono-level
signals direct from turntables. An
internal phono preamplifier applies
the standard (RIAA) phono reequalization, and amplifies the raw
cartridge signals to line-level.
Suppose you have a turntable
and a favorite record from when you
were young. Connect the phonolevel outputs of the turntable to the
Ch 13 and 14 1/4" inputs. (You might
need a pair of RCA to 1/4" adapters,
depending on your turntable.) Also
connect the turntable’s ground wire
to the mixer’s rear panel ground
screw. Play the record and adjust
the GAIN (4) as normal, so the LEVEL
SET LED (5) just lights. Select SOLO
(18) to hear it in the control room or
headphones, or press L-R to send it to
your main mix.
Caution: DO NOT press
the line/phono switch
down if you are putting in
a line-level signal (or if your
turntable already has linelevel outputs). This could overload the
mixer and damage your hearing.
21. LINE/USB switch
(channels 15 and 16 only)
In the up position, channel 15 and
16 accept line-level signals.
In the down position, the stereo
channel is not fed by its 1/4" inputs,
but by the rear panel USB port
connected to a computer.
In the mixer’s USB section, the
digital audio output from software
such as Tracktion is converted to linelevel, two-channel analog, that feeds
channels 15-16 just before the GAIN
(4) knob.
For example, suppose you have
recorded and mixed a lovely tune
using Tracktion software. You can
select Play in Tracktion, and press this
LINE/USB switch in to get the signals
into the mixer. Adjust the channel
GAIN (4) as normal, so the LEVEL SET
LED (5) just lights. Press L-R (16) to
send it to the main mix.

This is where you connect the outputs of your
intermission entertainment. Any line-level mono or
stereo device can be used, such as: tape, DVD/CD
player, television audio, etc.
Signals coming into these inputs are routed
directly to the CD/TAPE TO MAIN MIX (49) control
and through to the main mix. You will need to MUTE
(14) all the other channels, if you just want to hear
the CD or Tape.
The signals can also be routed to the control room
and headphone when the control room/phones
source select CD/TAPE (42) switch is pushed in.
When connecting a mono device (just one cord),
you’ll need a “Y-splitter” RCA adapter. It turns a
mono output cord into two cords, so both the right
and left tape input jacks can be used. This adapter
is widely available. See Appendix B for more
information about RCA connectors.
Caution: There is a chance of feedback
if you have the tape inputs and outputs
connected to the same recorder, and the
recorder is in record mode.
26. CD/TAPE OUTPUTS
Use these RCA jacks to capture the entire
performance to tape. The output signal is a direct
copy of the main mix, as it appears at the MAIN
MIX (58) outputs and the USB (62) output to your
computer.
You could also use these outputs to connect
to the unbalanced RCA inputs of a home stereo
amplifier, if you had a mind to.
Do not use long runs of unbalanced cables, or
there might be signal degradation and noise. Try
using good quality cables as sold in Hi-Fi stores.
Use the tape player’s record-level control to set
up the correct levels for recording. Take care if you
use the MAIN MIX FADER (52) to adjust the levels, as
this will affect your MAIN MIX (58) outputs as well as
these Tape outputs.
MASTER SECTION
So far, we have described the channels, and how
the signals from all of your microphones, instruments,
line-level sources and CDs or Tapes get onto the
main mix buses, subgroups 1 to 4, and the Aux
buses. Now we come to the Master section, that
controls what happens next.
27. POWER LED
This light glows when the mixer is turned on. If it is
off, the mixer will sulk and not work. Check that the
rear panel power switch is on, that the power cord
is plugged in, and any power strips or wall switches
are on. Also check if all the lights are out in your
neighborhood. You never know.

The magnificent seven sliders allow you to

Each slider varies the level by ±15 dB either side of
unity gain. The frequency bands are 64 Hz, 125 Hz,
400 Hz, 1 kHz, 2.5 kHz, 8 kHz and 16 kHz.
Adjust the EQ wisely and subtly. Do not overdo
the EQ gain, as this might lead to overloading or
clipping. Think of it like makeup, it should be applied
sparingly for a lovely effect, not caked on like wall
plaster.

This switch lets you assign the EQ (31) to either the
main mix or the Aux 1 stage monitor mix.
In the up position, the main mix will pass through
the EQ, and the monitor mix is not affected. You
can then adjust the sound of your main speakers,
and compensate for the effects of the room
environment.
In the down position, the stage monitor mix passes
through one side of the stereo EQ, and the main mix
is not affected. You can adjust the EQ to prevent
mic or guitar feedback from the stage monitors, or
allow the band to hear the monitors more clearly, or
less clearly if that helps any.
33. EQ BYPASS
This switch allows you to quickly bypass the EQ

For an example: for a reverb effect, a low number
will have a short reverb time, and a larger number
will have a longer reverb time.

The internal effects circuit receives mono signals
from the AUX 2 FX bus, and it outputs stereo signals
onto the main mix buses. It also adds a summed
mono signal to the stage monitor mix (AUX 1 bus).
The outputs are controlled by two FX RETURN (45, 46)
knobs described on the next page.
Inside the processor, the analog audio is
converted to digital, this is processed, and the result
converted into stereo analog signals.
Spicy curry can also result in some remarkable
internal effects, many in the audio frequency range.

This knob allows you to adjust the signal level
going into the internal effects processor. This is
useful if the signal is too strong, and the processor
becomes overloaded.
If you see the FX OL overload light come on, turn
down the knob until it just turns off during the louder
passages, riffs, chords, yells, etc.
37. FX BYPASS and LED
Press this switch in to bypass the internal effects
processor, and so prevent its output from appearing
on the main mix or stage monitors. The LED reminds
you whenever the processor is bypassed.
Use BYPASS if you are not using the internal
effects, as it will reduce any extraneous interstellar
noise, or use it to quickly compare between the
effective effect of effects and the effect of no
effects.
38. USB OUTPUT: MAIN MIX/SUBS 1-2
This switch allows you to choose if the main mix or
if subgroups 1 and 2, are sent out of the mixer’s USB
(62) output to your computer.
If pressed in, the A/D converters of the USB
section receive the output from subgroups 1 and 2
(before the SUB FADERS (50)). This is a good position
for studio recording and overdubbing with your
computer.
If pressed out, the A/D converters receive the
main mix (after the MAIN MIX FADER (52)), just
the same program as your main speakers and
tape deck will receive. This is a good position
for recording the main performance onto your
computer.
Further details of the USB connections and
operation are described on page 19.
39. USB OUTPUT LEVEL and OL LED
The USB section has an A/D converter that
converts the selected analog channels into a digital
stream.
This knob allows you to adjust the signal level
before it reaches the A/D converters. Turn it down If
you see the OL light come on.
Like all OL overload LEDs, this is an important one
to keep an eye on, so the outputs to your computer
are not distorted.
40. PHONES
This adjusts the headphone levels without
disturbing the main mix or control room levels.
Turn this down before connecting and putting on
your headphones, or before engaging any switches.
Bring it up slowly.
Caution: Be very careful because the
PHONES (30) output can drive any
standard headphones to very loud levels.
Please see page 2 for information on
hearing protection.
41. CONTROL ROOM
This adjusts the output level to your control
room, from the source selected using the SOURCE
SELECT (42) switches below. It does not affect the
headphones level or the main mix level.
42. SOURCE SELECT Switches
Use these four switches to select the signal source
for the control room outputs, headphones, and
meters.
Caution: Turn down the CTRL ROOM (41)
and PHONES (40) knobs before pushing
these switches.
When the switches are up, the control room
outputs, headphones, and meters receive no signals
(unless any channels have SOLO (18) engaged).
Push MAIN MIX to hear the main mix.
Push CD/TAPE to hear your CD or Tape player.
Push SUBS 1-2 to hear subgroup 1 and 2 outputs.
Push SUBS 3-4 to hear subgroup 3 and 4 outputs.
Note: If any channel has its SOLO (18) switch in, then
only the SOLOed channels are heard in the control
room or headphones.
43. AUX 1 (MON) MASTER SEND
This knob is the master level control of the AUX
SEND 1 MON (22) output jack. Adjust this knob to
control the overall level of your stage monitor mix.
44. AUX 2 (FX) MASTER SEND
This knob is the master level control of the AUX
SEND 2 FX (23) output jack. Adjust this knob to
control the level sent to your external processors.
45. FX RETURN TO AUX 1 MON
This knob allows you to adjust the level of the
effects going onto the AUX 1 MON bus and out to
your stage monitors.
Signals (from external processors) coming into the
AUX FX RETURN (24) jacks, and the internal effects
processor output (unless bypassed), are summed to
mono and added to the AUX 1 Monitor bus through
this level control.
The control ranges from minimum fully counterclockwise, to unity gain at the center, to +15 dB fully
clockwise.
46. FX RETURN TO MAIN MIX
This knob allows you to adjust the level of effects
going onto the main mix bus and out to your main
speakers.
Signals (from external processors) coming into the
AUX FX RETURN (24) jacks, and the internal effects
processor output (unless it is bypassed) are added to
the main mix bus through this level control.
The control ranges from minimum fully counterclockwise, unity gain at the center, to +15 dB fully
clockwise.
47. RUDE SOLO LED
This rather annoying light flashes on and off as
a reminder when any of the channel SOLO (18)
switches are pushed in. When flashing, you will hear
the SOLOed channel(s) in the control room and
headphones.
48. METERS
These LEDS show the level of the control room and
headphone signals, before the control room and
headphones level controls.
As the control room/phones source select
switches are engaged, you can view the levels of
the different sources (main mix, CD/Tape, Sub 1-2
and Sub 3-4).
The calibrations are: –24, –12, –4, 0, +4, +8, +12
and +16 dB (Clip), where 0 dB = 0 dBu.
You can get a good mix with the meter’s peaks
flashing anywhere between –24 and +8 dB. Most

try to keep your peaks between 0 dB and +8 dB.
If your meters are too high, you will get distortion.
If they are too low, then your signal-to-noise will

If the SUB ASSIGN TO MAIN MIX L and R (51)
switches above each fader are engaged, these
faders will affect the subgroup levels reaching the
main mix bus.
These faders also control the signal level out of
the rear panel SUB OUTS (61).
They also affect the level to the control room/
phones if the SOURCE SELECT (42) switches SUB 1-2 or
SUB 3-4 are engaged.
The faders range from minimum at the bottom, to
unity gain at 75% up, and to +10 at the top.
For an example of subgroups, suppose you have
a group of microphones to record a drum kit:
• Each drum microphone could be assigned to
subgroup 1-2 by pressing the channel 1-2 switches.
• Use the channel Pan controls to create a delicate
stereo mix between subgroup 1 and 2.
• Assign this to the main mix.
• Use the subgroup faders 1 and 2 to adjust the
sound of all drum mics in the main mix, instead
of having to tweak each individual drum mic
channel fader.
51. SUB ASSIGN TO MAIN MIX L and R
These switches allow you to assign a subgroup to
the main mix bus. The rear panel subgroup outputs
are not affected.
52. MAIN MIX FADER
This 60 mm stereo fader adjusts the level of the
main mix as it is sent out of the MAIN MIX (58) outputs
for audience entertainment, and TAPE (26) outputs
for recording for posterity/archiving/evidence.
It also adjusts the levels to the USB (62) outputs,
and control room/phones, if the main mix is set to be
their source.
This fader is what you use for the long drawn-out
fade out or fade-in. It ranges from minimum at the
bottom, to unity gain at 75% up, to +10 dB at the
top.

53. POWER SWITCH
Push the top of the switch labeled “ON” to turn
the mixer on; you should see the POWER LED (27)
glow with happiness. To turn the mixer off, push the
bottom of the switch.
As a rule, turn the mixer on first, before any amp
or powered speakers. At the end of a show, turn it
off last. This will prevent any turn-on/turn-off thumps
from being heard in the speakers.
54. PHANTOM POWER
Turn on this switch to provide +48 VDC phantom
power to the MIC (1) input XLR jacks (pins 2 and 3).
Phantom power is required to operate most
condenser microphones (some condenser
microphones are battery-powered).
If you have ribbon mics, tube mics, or dynamic
mics that do not require phantom power, leave the
switch out. If you are using both condenser and
dynamic mics, don’t worry. Phantom power will not
hurt most dynamic mics. Check the microphone’s
user manual if you’re not sure.
Caution: Turn all output levels down
before operating this switch to avoid the
possibility of a “pop” in your speakers.
Do not use phantom power with tube or
ribbon microphones, as this may cause
damage. Always turn off phantom power when
connecting or disconnecting your microphones.
55. AC POWER IN
This standard IEC connection is where you
connect the supplied power cord.
Connect the power supply cord to the Blend 16
first, then plug the power supply into a suitable and
properly rated AC outlet.
The Blend 16 has a universal power supply that
will operate with AC mains voltages from 100 VAC to
240 VAC.
56.AC FUSE
If you suspect a blown fuse, disconnect the power
cord, pull the fuse drawer out (located just below
the cord receptacle) and replace the fuse with
the same type and current rating. If two fuses blow
in a row, something is very wrong, and you should
unplug the mixer and call technical support.

57.PHONO GROUND
If you have a turntable connected, use this screw
terminal to connect the turntable’s ground wire. This
will prevent a hum in your system.
58. MAIN OUTPUTS
These 1/4" TRS jacks and XLR jacks represent the
end of the mixer chain, where your fully mixed stereo
signal entertains your audience.
Connect these outputs to the inputs of your
amplifiers, powered speakers, or serial effects
processor (graphic equalizer, for example).
59. MAIN INSERTS
These allow you to insert an external device such
as the Tapco SQUEEZE compressor/limiter or TWEEQ
graphic EQ into the main mix signal path.
You will need “Insert Cables” that allow the main
mix signals to go out to your external device, and
have the processed signals come back into the
mixer on the same plug (see Appendix B).
The inserts are taken directly from the main mix
bus, before the 7-Band EQ (31) and the MAIN MIX
FADER (52).
60. CONTROL ROOM OUTPUTS
These 1/4" TRS jacks can be used to monitor the
main mix, CD/Tape inputs, subgroups, or SOLOed
channels.
Use the control room SOURCE SELECT (42) switches
to select what you want to hear, all independent of
what the main mix outputs are playing.
Connect these outputs to the inputs of an
amplifier with speakers, or powered speakers for
monitoring.
61. SUBGROUP OUTS
These 1/4" TRS jacks represent the output from
your subgroups. You can connect them to amplifiers
or powered speakers, or send the outputs off to an
ADAT recorder (or not use them at all).
62. USB IN/OUT
One end of the supplied USB cable connects
here, and the other end connects to the USB port of
your computer. The USB cable can simultaneously
send and receive two channels of audio to and
from any Mac or PC audio software.

Appendix A: Using the Blend 16
A public transportation bus takes many passengers
and delivers them to various destinations. In a similar
way, an audio bus combines multiple audio signals
and delivers them to an output.
The Blend 16 has two main mix buses, two auxiliary
buses, and four subgroup buses.
Auxiliary 1 Stage Monitor bus
The Aux 1 Mon bus is normally used for sending
an output to your stage monitors, so the band can
clearly hear what they are playing, amidst the wild
frenzy of the audience.

The channel PAN knobs adjust the signal balance
onto the buses. Mono signals are shared equally to
the left and right bus if the PAN is centered. With PAN
fully left, the signals just go onto the left bus, and with

At first glance, the controls on the front panel of the
Blend 16 may seem more at home in a space movie,
right next to the Navigation officer. Like most things,
it’s worse than that really. Here is a brief overview that
may help you understand the basic functions and
mysterious inner workings of the Blend 16.
To get signals onto the Aux 2 FX bus, rotate the AUX
SEND 2 controls located just below the EQ section of
each channel strip.
Unlike Aux Send 1, the levels going to Aux Send 2
are affected by the channel faders. (As the channel
faders are changed, the signal levels going to the
internal and external processors change.)

subgroup can be adjusted with its own SUB FADER,
assigned to the main mix, and/or sent out of the sub
output jacks for recording.
To get signals onto the subgroups, press the 1-2, or
3-4 buttons near the bottom of each channel strip.
Careful use of each channel’s PAN can create a
nice stereo image in subgroups 1 and 2, or in 3 and 4.
If you want a channel to only go to 1 (or 3), pan fully
left; for 2 (or 4), pan fully right.
To get subgroups onto the main mix, press the L
and/or R buttons above each SUB FADER.
Control Room and Phones Section
The control room section lets you select and
monitor the main mix, the CD/Tape player, subgroups
and listen to individual SOLOed channels, all without
interrupting the main mix. You can set up a separate
amplifier and speakers for a studio control room,
Uncle Ernie’s control shed, or headphones.
Solo
Any channels with their SOLO button engaged, will
have their signals sent (pre fader) to the control room
output and headphones for monitoring. This does not
affect the main mix, so your band can still play on
while you check individual channels and weed out
Mr. Out-of-Tune from the boy band.
USB and the Blend 16
One of the cool features of the Blend 16 is its
integrated USB input and output. Among other things,
this allows you to record your live shows, perform
recording sessions in your home studio, or use your
computer as a jukebox/band member during live
performances, with only your mixer, a computer and
a USB cable. No extra computer audio interface
hardware is needed.
Before you can get started, you may need to install
the drivers. See the instructions included on the Blend
16 software CD.

each L-R switch up).
4. Use PAN on each channel to select if the mics or
instruments go to subgroup 1 or 2. For example, to
record a vocal microphone and an electric guitar
at once, route the mic to subgroup 1 (PAN fully left,
and 1-2 down) and the guitar to subgroup 2 (PAN
fully right, 1-2 down).
5. Press the USB SOURCE switch down; copies of
subgroups 1-2 are fed to the USB’s A/D converter
and sent to your computer’s DAW software.
6. Sing or play, at normal performance levels and
adjust the USB OUTPUT LEVEL knob to avoid
clipping the USB A/D converter.
Here is where Direct Monitoring comes in:
7. To listen to the direct sounds as you record, assign
subgroups 1-2 to the main mix, using the L and R
switches above the subgroup faders. Carefully turn
up the Control Room level and/or Phones level
a little, then use the subgroup faders to control
the volume of what you are hearing. (They do
not affect the signal levels sent to the computer,
since the signals are tapped before the subgroup
faders.)
Configuration:
1. Follow steps 1 to 6 above to get your sounds into
the computer, using subgroups 1-2. Do not assign
the subgroups to the main mix.
Here is where Software Monitoring comes in:
2. To listen through the software as you record,
engage software monitoring in your DAW for the
Blend 16 inputs. You will then be able to listen to
the tracks while you are recording, including any
software effects you might have added. This is
done differently for each DAW, so consult your
software’s manual if you are unsure how to do this.
In Tracktion, you would enable “end to end” on
the Blend 16 inputs.

3. On your DAW, place any software effects you
would like to “monitor through while recording”
onto the tracks coming in from the Blend 16.
4. Press the USB button on channels 15-16 and assign
15-16 to the L-R, but not to subgroups 1-2.
5. Press Main Mix in the Control Room source section
and you will hear the signals you will record
(through their effects) along with playback from
any previously recorded tracks.

8. To perform an overdub and hear some previously
recorded material (such as a drum beat) to play

Main aim:
Use the computer as a sound source for playback
during a live performance, or as the main sound
source for their DJ set.
Configuration:
• Setup your mixer for your live show as you normally
would, but leaving channels 15-16 unused.
• Open your music software on your computer and
configure it to output to the Blend 16.
• Press the USB button on channels 15-16. The
output of your computer will now feed these
channels.
• Using the channel 15-16 controls, route the
incoming audio from your computer to the Auxes,
Effects sends, subgroups, and/or Main L-R as
needed, just as you would any other channel.
• If you would also like to record your show, you
can send your main mix back to your computer
for recording. Be sure software monitoring is NOT
enabled in your DAW or you might get a feedback
loop and could damage your ears and speakers.
Appendix B: Connections
XLR Connectors
1/4" TS Phone Plugs and Jacks
Channels 1 and 2 use 3-pin female XLR
connectors on the MIC inputs. They are wired as
follows, according to standards specified by the AES
(Audio Engineering Society).
“TS” stands for Tip-Sleeve, the two connections
available on a mono 1/4" phone jack or plug. They
are used for unbalanced signals.

may need to use a special 1/4" TRS connector
called an “Insert plug.” These use the tip to send the
signal to the external device, and the ring to return
the signal to the mixer. The sleeve is the common

Appendix D: Service Information
Warranty Service
Details concerning Warranty Service are spelled
out in the Warranty section on page 27.
If you think your TAPCO Blend 16 has a problem,
please do everything you can to confirm it before
calling for service. Doing so might save you from
the deprivation of your mixer and the associated
suffering.
Here are some things you can check:
Troubleshooting
Bad Channel
• Is the channel GAIN turned up?
• Is the channel FADER turned up?
• Try the same source signal in another channel, set
up exactly like the suspect channel.
• If your microphone requires phantom power, make
sure you engage the Phantom Power button
(48V) on the rear panel of the mixer. Confirm the
need to use phantom power by reading your
microphone's documentation.
Bad Output
• Is the MAIN MIX FADER at minimum perchance?
• If it’s a stereo pair, try switching them around. For
example, if a left output is presumed dead, switch
the left and right cords, at the mixer end. If the left
speaker is still dead, it’s not the mixer. Perhaps it’s a
bad cable, speaker, or amplifier channel.
Noise
• Turn down the channel FADER, and AUX SEND
controls, one by one. If the noise disappears, it’s
either that channel or whatever is plugged into it,
so unplug whatever that is.
Power
• Our favorite question: Is the POWER switch on?
• Is the power cord securely plugged in?
• Is the power supply cord securely plugged into
an AC power strip? Make sure the power to the
power strip is turned on.
• If you suspect a blown fuse, disconnect the power
cord, pull the fuse drawer out (located just below
the cord receptacle) and replace the fuse with
the same type and current rating. If two fuses blow
in a row, something is very wrong, and you should
contact technical support.
• Are all the lights out in your building?
No Audio into your Computer:
• Confirm the mixer is receiving mic or instrument
input signals.
• Make sure you have selected the right driver in
your DAW. In Tracktion, this is in the Settings menu.
• If the mixer seems fine, click Restart Device in the
Tracktion Settings menu.
• In Tracktion, be sure the correct inputs are selected
and the tracks are armed.
Echo or phasing from input while
recording:
• It sounds like you are monitoring both through
software and directly. You should only do one or
the other. See page 19 to help you decide which is
best for your situation.
• If you are overdubbing (or recording a new track
alongside other tracks already recorded), try
disabling your new track’s output to the mixer and
monitoring the signal you are recording directly.
Adjust the channel 15-16 fader and the subgroup
1-2 faders so you can hear both your new input
signal as well as the playback from the computer.
Glitchy/Distorted Playback from
Computer:
Increase the Buffer Size/Latency Setting:
• Tracktion (PC): choose the Settings Tab and Audio
Devices. Click the “show ASIO control panel”
button and try a larger buffer size.
• Tracktion (Mac): choose the Settings Tab and
Audio Devices and increase the Latency slider.
• In other applications, find the control panel to
increase the ASIO (PC) or Core Audio (Mac) buffer
size or latency.
• Be sure the mixer is the only device on the USB
chain. The easiest way to do this is to be sure the
mixer is connected directly to your computer’s USB
port; we do not recommend using USB Hubs.
• Try a song with fewer tracks, effects, and virtual
instruments. If it plays fine, then you may be
pushing your computer above its limits. Try
increasing your latency settings as described
above.
Large latency (delay) from input
signal to output:
• Change the latency/buffer setting to a lower
setting, as described above.
• Try using direct monitoring instead of software
monitoring. See page 19 for details.
25
No Communication with the mixer:
• The PC driver may not be installed correctly.
Make sure your computer meets the system
requirements. Uninstall the driver from the Add/
Remove Programs control panel, restart your
computer, and reinstall the driver.
• Restart your computer and the mixer.
I hear my Windows/Mac sounds
through my mixer, but I don’t want to:
The mixer should not be selected as your computer’s
sound system default device. To disable it:
• On a PC, go to Control Panel>Sound and Audio
Devices. In the Audio tab, be sure the Blend 16
is not selected as the default device for sound
playback.
• On a Mac, go to Applications>Utilities>Audio
MIDI Setup. In the Audio Devices tab, be sure the
Blend 16 is not selected for your default or system
outputs. You can also change this in the Sounds
Preferences pane of the OS X System Preferences
application.
My guitar (or other instrument)
doesn’t sound as good as I expect:
• If your guitar is connected directly to the mixer
(i.e., without a direct box or preamp), be sure you
are using the INST input on channels 1-8.
• Check the mixer Gain and EQ settings, and make
sure you have not overdone the EQ or the audio is
clipping.
Repair
Service for Tapco products is available at a
factory-authorized service center. Service for Tapco
products living outside the United States can be
obtained through local dealers or distributors.
If your unit needs service, follow these instructions:
1. Review the preceding troubleshooting suggestions.
Please.
2. Call Tech Support at 1-877-827-2669, 7 am to 5 pm
PST, to explain the problem and request a Service
Request Number. Have your serial number ready.
You must have an Service Request Number before
you can obtain warranty service.
3. Keep this owner’s manual and the detachable
linecord. We don’t need them to repair the unit.
4. Pack the unit in its original package, including
endcaps and box. This is VERY IMPORTANT. Tapco
is not responsible for any damage that occurs due
to non-factory packaging.
5. Include a legible note stating your name, shipping
address (no P.O. boxes), daytime phone number,
Service Request Number, a copy of your sales
receipt, and a detailed description of the problem,
including how we can duplicate it.
6. Write the Service Request Number in BIG PRINT on
top of the box. Units sent without the SR number
will be refused.
7. Tech Support will tell you where to ship the unit
for repair. We suggest insurance for all forms of
cartage.
• Yes, but please follow all copyright rules.
8. You will need to contact the authorized service
center for their latest turn-around times. The unit
should be packaged in its original packing box,
and must have the Service Request Number on
the box. Once it’s repaired, the authorized service
center will ship it back by ground shipping, prepaid (if it was a warranty repair).
• Mixer channels 13 and 14 can accept phono
level signals from a turntable. The internal phono
preamp equalizes and boosts your turntable
phono-level signals to line-level.
Note: Under the terms of the warranty, you must
ship or drop-off the unit to an authorized service
center. The return ground shipment is covered for
those units deemed by us to be under warranty.
• It is most likely that your turntable has RCA
outputs, so you will need to buy adapters from
RCA (female) to 1/4" (male). These adapters are
commonly stocked in most electronics and audio
stores.
Note: You must have a sales receipt from
an authorized Tapco dealer for your unit to be
considered for warranty repair.
• Could we suggest you might need more practice?
Can I transfer my classic record
collection?
• Some companies provide software plug-ins that
remove pops and clicks from the recordings. This
kind of spoils some of the fun though.
Still having USB problems?
• Be sure you are running the latest drivers.
• If after updating, you still are having problems,
please call tech support.
