Datavideo AD-300

AD-300 is an easy to use audio delay box to enable you to synchronise video and audio. The new AD-300 professional audio delay box is equipped with 5 input channels and 2 output channels as well as the capability of processing multiple audio inputs for your live production. Built in a rugged metal housing for use in the field or studio setup.

With the AD-300, you will be able to delay the audio input for up to 3,000 ms, mix multiple audio inputs in different combinations and apply various audio dynamics effects such as audio equalization and filtering, etc. You can also fine tune each audio input individually to gain a professional audio experience and precise audio/video synchronization. Moreover, the equalizer allows you to customize the audio effect by adjusting the audio volume (± 10 dB) of up to eight frequency bands ranging from 125 Hz to 16 KHz.

The 2 inch LCD screen on the front panel gives you access to all of the functions that the AD-300 provides.  Compressors and limiters adjust the volume of the audio inputs with a maximum compression ratio of 100:1 in the compressor. Expanders and gates make certain instrument and human voice sound more prominent with also a maximum attenuation ratio of 100:1 in the expander. The built-in balanced and unbalanced audio conversion ensures that the audio output is always in the right format. The Line/MIC switch allows you to switch between microphone and line inputs. In addition, the 48V phantom power is included to power connected condenser microphones. These powerful features are housed in a compact case, ideal for standalone and rackmount applications.
