Radial Engineering has announced the Presenter, a compact audio mixer that combines a microphone preamp and a USB program input to create a computer, sound system or speaker interface for any type of presentation.
Radial said the Presenter provides a simple, high-quality solution where a microphone and a playback source needs to be mixed together and sent to a sound system or computer.
The Presenter begins with an XLR mic input to connect an external microphone and provides it with 48 volt phantom power. The mic signal can then be adjusted using three EQ controls: a high-pass filter rolls off excessive low end, while low and high controls allow the frequency response to be tailored.
A USB program input on the back of the Presenter provides audio playback from a laptop. The USB input also provides power for the Presenter, eliminating the need to carry around a separate power adapter. USB can also be used for recording.
To connect the output from a portable device such as a smartphone or tablet, a 3.5mm TRS connector is built into the front panel of the Presenter, and is controlled using the same level knob as the USB audio input. The Presenter automatically senses when the 3.5mm input is in use, and mutes the USB signal. Once disconnected, it automatically switches back to the USB connection for seamless playback.
Both the microphone and playback signals are mixed to stereo XLR balanced outputs. A mono switch is provided if only one speaker is needed, and a ground lift ensures that the output signal is clean and free of any buzz or hum from ground loops.
The Presenter is priced at $299.99.
