A professional sound delay box that meets the needs of multiple functions.

The AD-300 is equipped with a wide range of input and output interfaces and sound processing functions to fulfill the needs of professional audio production. The input audio source can be processed for sound delay, mixing, equalizer, compressor, limiter and other sound effects.

Wide range of input options

The AD-300 is equipped with a wide range of input and output interfaces. 3 XLR balanced stereo inputs and 2 RCA unbalanced stereo inputs; the output provides two channels of XLR and RCA.

Sound Delay Range 0~3000ms

The AD-300 professional audio delay device has a 3000 ms audio delay range, and each input can be adjusted individually in milliseconds to achieve professional-grade sound and video synchronization.

Built-in Mixing Function

The built-in mix function allows you to select any of the five input sources that you want to mix and combine them into a single output channel. A Test Tone can be added for volume correction.

Equalizer for adjusting timbre

You can set a specific frequency range and then adjust the volume of that specific frequency range only. The equalizer of AD-300 can adjust each channel from 125Hz to 16K Hz in 8 frequency ranges, each adjustable by ± 10 dB, to produce the various tone effects you want.

Audio filter

Filters are being used to remove groups of frequencies from an audio-signal. High-pass filter cuts out all frequencies below a user-determined cutoff point. And low-pass filter cuts out all frequencies above a user-determined cutoff point. 

Balanced/unbalanced audio conversion

The built-in balanced or unbalanced audio conversion prevents under-volume or popping in case of misuse. When unbalanced and balanced audio conversion is required

When unbalanced and balanced audio conversion is required, the AD-300's audio conversion function will ensure that the sound output matches the desired format.
