RELEASE NOTES

& UPDATE INSTRUCTIONS

EasyUSB Mixer/Amp

Current Release

EasyUSB Mixer/Amp V01.22.00

September 13, 2019
New Features

• Added commands to enable and disable buttons on a connected TableMIC microphone.
Call button: 6135 xx (01 = enable, 00 = disable)
OneTouch button: 6136 xx (01 = enable, 00 = disable)
Mute button: 6137 xx (01 = enable, 00 = disable)

Volume Up/Down buttons: 6138 xx (01 = enable, 00 = disable)
Volume meter: 6140 xx (01 = enable, 00 = disable)

Improvements

• Serial API Kit has been reorganized and clarified.

• Previously a preset button press from TableMIC or EasyMic Table MicPOD microphones sent the preset

command to a camera multiple times. This has been fixed.

Notes

• When the DIP switches on the EasyUSB Mixer/Amp are configured for both VC Bridge Mode and Audio
Delay Mode, EasyMic audio will be incorrectly routed to the speaker outputs. To fix this, set the switches
to select either VC Bridge Mode or Audio Delay Mode, but not both.

EasyUSB Mixer/Amp V01.20.02

December 14, 2016
New Features

• A serial RS-232 command has been added to set automatic gain control (AGC) ON or OFF for EasyMIC
microphones. The returned command response will indicate the current AGC state, and will indicate if an
EasyMic is connected. The Mixer/Amp saves the setting whether an EasyMIC is connected or not, and
retains the setting through reboots and power cycles.
Enable AGC: 6130 01

Disable AGC: 6130 00

Improvements

• In the previous version, Vaddio Loader did not update MicPOD microphones properly. This has been
fixed.

May 9, 2016
Improvements

Table MicPOD.

Conference mixing mode.

• Speaker EQ DIP switch is now active during runtime. In previous releases, it required a power cycle to
take effect.

• USB playback maximum gain range has been adjusted to offer improved USB volume adjustments.

• “Set Playback Volume” RS-232 serial command has been improved to arrive at the specified volume level

faster.

• Corrected an issue where audio distortion could be present on certain combinations of Mac OS X and
hardware platforms.
