Appendix D: Service Information

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 it’s 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.

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 

 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 

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 

 switch on?

•  Is the power cord securely plugged into the Blend 

16?

•  Is the power supply cord securely plugged into 

an AC power strip? Make sure the power to the 
power strip is turned on.

•  Is the mixer set to the correct voltage?
•  Are all the lights out in your building?
