DIGIGYSN LINK-embedded
Equipped with the DL-08D network audio module, it seamlessly supports the AES67 protocol, enabling interoperability with all AES67 network devices. It provides a 4×4 network transmission channel, offering ultra-low latency, stability, and high-quality audio networking. The DMX208L combines the stagebox and DSP processor into one unit, reducing system complexity, saving on the number of devices in the network, and budget.
Now supporting SMPTE ST2110-30
Since July 2025, all devices upgraded to firmware version 3.1.4.67 or later have gained support for user-configurable DSCP QoS priorities, PTP domains (Precision Time Protocol Domain), and multicast port numbers. This enhancement ensures the devices fully meet the stringent requirements of broadcasting network environments for advanced Quality of Service (QoS), precise clock synchronization, and flexible multicast management.
1U rack chassis
Standard 1U design chassis.
8-channel GPIO Outputs
GPIO is a kind of pin of a microcontroller or other integrated circuits, and it can be configured as an input or an output. The 8-channel GPIO output means that 8 such pins are configured in the output mode. These pins can be used to control external devices, such as LED lights, relays, motor drivers and so on.
DIGISYN LINK3 GUI Controller
Utilize the DIGISYN LINK 3 free control software to achieve a combination of DSP, audio routing, and online monitoring.
PoE and DC Dual power
The PoE-af standard provides 15W power supply and also supports DC 12V/1.5A.
Customizable DSP
The system features a fully configurable, powerful DSP with comprehensive functions including equalization (EQ), compression, FIR filtering (with up to 4096 taps), delay, noise gating, limiting, feedback suppression, high/low pass filtering, mixing, and more. It also integrates advanced algorithms such as Automatic Noise Suppression (ANS), Automatic Frequency Control (AFC), Automatic Gain Control (AGC), Acoustic Echo Cancellation (AEC), Active Noise Cancellation (ANC), and Auto Mixer (AM) for optimal audio processing performance.
XLR interfaces and Phantom Power
4 x 4 XLR terminal inputs and outputs. The inputs can provide 48V phantom power for microphones.
