System Configuration and Programming
EasyUSB Mixer/Amp:
The EasyUSB Mixer/Amp has an eight pin dip switch on the rear of the device for allowing installers to customize
product for the desired conferencing application. Available configuration functions are listed in Table below. The
“up” position on the dip switch represents enable and the “down” position represents disable.
Table: EasyUSB Mixer/Amp Dip Switch Configuration Settings
Function Description
Default USB Conference
Mode This mixing mode sums the Line Input with the EasyMic audio and
sends it to the USB Transmit. The USB Receive is sent to the amplifier
output, Line Output, and AEC Reference. This will be the default mixing
operation when no switches are enabled.
1 RS‐232 Mode This mode switches the RS -232 port configuration from a DCE to a
DTE device. If DIP 1 is Down (disabled), the Mixer/Amp RS-232 port is
configured as a DCE device, allowing direct connection to a DTE
device such as a PC's RS-232 port or a WEBBi controller device. If
DIP 1 is Up (enabled), the Mixer/Amp RS-232 port will be configured as
a DTE device, allowing direct connection to a DCE device such
as the HD-USB camera. This switch setting takes effect immediately -
no power cycle required.
2 V/C Bridge Mode* This mixing mode bridges the audio between the USB and an external
Videoconferencing unit connected to the line input and output.
3 Recording Mode * This mode is intended to allow users to record both the local and far‐
end audio. The audio mix for the local EasyMic devices and the USB
audio from the far‐end will be sent out the line output on the
Mixer/Amp.
4 Speaker EQ Filter The speaker EQ filter enables a specialized EQ filter on the speaker
outputs for enhanced clarity in the voice band for improved
intelligibility in conferencing applications. Requires power cycle.
5 Compressor &
Level Control This function enables a compressor/limiter along with an automatic
level control on the speaker outputs of the EasyUSB Mixer/Amp. This
function is intended to produce a constant speaker output level
independent of the audio source content originating from the far‐end.
6 Audio Delay A 25 millisecond audio delay can be injected into the speaker outputs.
This is intended for better lip sync alignment when used with LCD
displays with significant video processing delays.
7 AEC Disable This function disables the Acoustical Echo Cancellation functions on
the EasyMic devices. This should only be used in non‐conferencing
applications.
8 Firmware Update This switch places the EasyUSB in firmware update mode allowing
installers to upgrade the device using Vaddio software. When
enabled, the audio operations will be disabled during the firmware
update procedure. (Requires Power Cycle to take effect).
