Beam 4 is the flagship model in Audirect's portable DAC series.
The DAC uses the latest ESS9281 AC PRO.
Like conventional Audirect products, it is possible to play up to 32Bit/768kHz PCM and up to 512 DSD, making it a model that is well compatible with high-resolution sound sources.
In addition, although it is small, three crystal oscillators equivalent to femtoseconds are used to produce more accurate and noise-free sound.
In addition, it is equipped with a built-in battery, and the company's original MCU power management system provides thorough power management
Controlling the current to operate between 3.85V 〜 4.2V is a challenge for portable DACs (dongle types)
By eliminating the effects of power by the maximum amount of d and maintaining stable output, we have achieved stable sound quality.
Furthermore, power management also contributes to extending battery life.
◎Equipped with its own power management system
By adopting a battery system developed in-house and managing and controlling the power supply, we have achieved a stable power supply.
Control current to operate between 3.85V 〜 4.2V, and prioritize Beam4 built-in battery,
If your Beam4 built-in battery runs out of power, just like traditional non-battery portable DACs
We obtained power from the connected device side and achieved stable sound supply for a long period of time.
*Like a mobile battery, connected devices cannot be charged.
◎button volume adjustment/playback stop/song feed back/gain adjustment/LED decoding type can be recognized
In addition to the power button, the physical button allows you to adjust the volume, stop playback, send and return songs, and adjust the gain.
It is also possible to check the decoding type using LED.
*The connected device, iPhone, iPad, etc. will adjust the volume in conjunction with the main unit.
The gain button on the side allows you to adjust the gain to three levels: LOW, MID, and HIGH according to the efficiency of your earphones and headphones.
The color of the indicator light changes depending on the decoding type.
Red: 44.1/48kHz PCM
Indigo: 88.2kHz-384kHz PCM
Green: 705-768kHz PCM
Yellow: Dop
White: DSD Native
◎2 interfaces to meet user needs
Equipped with two types of headphone jacks.
Equipped with 3.5mm single end/4.4mm balance.
You can enjoy it with a variety of earphones/headphones.
◎balanced sound in all bands
The sound floor has just the right thickness and density in all bands, with an emphasis on overall balance and detail
We have created a transparent sound typical of Audirect that brings out the best in your earphones and headphones.
