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.

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.

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. 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. 

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.

The Compressor reduces the level of the high volume sound signal and maintains the original level of the low volume sound signal, thus reducing the dynamics range of the sound signal and adjusting the rise and fall of the audio track. The AD-300's compressor can achieve a 100:1 compression ratio (Ratio), and the Attack time can be adjusted from 50 to 500 msec, allowing you to adjust the audio dynamic range to your ideal.

Limiter is a function used to limit the dynamic range and is often used in combination with Compressor. It controls the maximum volume of the entire track and is adjusted at the end of Mastering. The Threshold range of the AD-300's Limiter is +24dBu to -6dBu, and the Attack time can be selected from 50 to 500ms.

The Expander is the opposite of the Compressor and is used to expand the dynamic range of the sound, making the louder and quieter parts of the Threshold range louder and quieter, respectively. The Expander can be used to make more noticeable changes in the volume of instrumental music or vocals.

If the volume is less than the set threshold range, it will be muted to silence, which is the function of the gate. Gate is mainly used to remove unwanted audio. For example, it can be used to eliminate the breathing noise of the vocal sounds. The Gate threshold of the AD-300 can be adjusted from -66 dBu to -25 dBu.

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. 

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. Switchable for Microphone input or Audio Line input and Supports XLR mic in and +48V phantom power.

LCD display for OSD menu and mode selection. The body design is suitable for stand-alone or installation in the rack.

I was really happy with the value of money I pay for this set because I’m able to make the perfect cup of coffee at home and save on going to Starbucks or Dutch Bros. They taste so yummy. It’s easy to use.

Café-Quality Sauces at Home ☕🍫
Flavor Name: Variety Pack 2, Size: 16.5 fl oz (Pack of 4), Flavor Name: Variety Pack 2, Size: 16.5 fl oz (Pack of 4)
Absolutely love this Torani Puremade variety pack. Every sauce tastes rich, smooth, and high quality just like what you’d get at a coffee shop. The caramel is perfectly buttery, the white chocolate is creamy (not overly sweet), and both chocolate sauces are deep and indulgent. They blend beautifully into hot and iced drinks, drizzle great over desserts, and the squeeze bottles make them super easy to use with no mess. I also really appreciate that they’re made with no artificial flavors or preservatives. If you’re building a home coffee bar or love elevating desserts, this set is 100% worth it. Would definitely repurchase.

Gourmet drizzle of deliciousness
Flavor Name: Variety Pack 2, Size: 16.5 fl oz (Pack of 4)
Torani is a great product - very happy we were able to order them through Amazon. They last without being refrigerated (but we go through them fast during parties). The syrups taste like they're from an ice cream shop - we use them for ice cream parties for variety. This set is a great price compared to buying in-store. The syrup is not watery, it's a nice thick syrup that is great for coffee or desserts. The consistency is not as thick as a fudge topping, but thick enough to drizzle, if that makes sense. Will buy again!
