(1) The processor chip adopts ADI architecture, no less than 40 bit DSP floating-point operation engine, and provides free configuration software architecture.(2) The panel is made of high-grade materials with elegant design.(3) The host is equipped with an OLED color screen, which displays the device name, IP address, version firmware,input and output channel signals in turn.(4) With up and down keys to turn pages to view equipment information, LED channel signal indicator with red, green and yellow.(5) It has a soft control switch with red and green prompts, red for standby, green for startup, long press to switch.(6) Terminal user interface can be provided to realize centralized control of multiple devices. Third-party devices can be controlled through UDP, RS232 and RS485 of the machine, and control software codes can be viewed.(7) Each channel has independent and automatic adaptive feedback suppression.It has processing modules such as AFC (feedback suppression), AEC echo cancellation, ANS (noise suppression), AGC (automatic gain), gain sharing threshold and automatic mixing.(8) With 12×9 matrix, full-function matrix mixing, adjustable input mixing level.(9) 8-channle balanced microphone/line input, 8-channel balanced audio output, using Phoenix plug interface.(10) Customized operating software makes the configuration more flexible and can control DSP of different specifications.

(11) Built-in USB sound card facilitates easy transmission with PC audio signal, supports recording and remote conference.(12) 8 GPIO canbe independently configured for input and output, and can be used as an independentADC when the input is configured.(13) 32 groups of scene presets, expandable to 50 groups. It can be used in any scene, which is convenient for different occasions.(14) Permission and password setting functions, super administrator, general user and visitor permissions can be set.

(15) Hot-backup of master-slave dual computers can be set. All configurations of the master computer are backed up to the slave computer in real time. When the master computer is disconnected due to a fault, the slave computer outputs audio in real time.(16) Support channel shell, LINK and grouping functions.(17) It has an editable operation interface, and each channel can select the configuration of evader, noise gain compensation, 5-segment parameter equalization, 12-segment parameter equalization, 10-segment graphicequalization, 15-segment graphic equalization, and 31-segment graphic equalization.(18) Intelligent automatic camera tracking function.(19) Fire linkage function.(20) Multiple control modes, which can be managed through web pages, mobile phones, tablets, key panels, touchpanels, etc.

GoFutura digital audio processor (DSP) is a 1U rackmount unit that cleans, mixes and routes every microphone and speaker signal. With echo cancellation, feedback suppression and automatic gain control, it ensures consistent speech clarity across classrooms and meeting rooms.

What Does a DSP Do in a Classroom Audio System?

A digital audio processor (DSP) is the control center of a modern sound reinforcement system. It takes audio from microphones and other sources, applies processing, and sends optimized sound to amplifiers and speakers.

Key functions include echo cancellation for hybrid video calls, feedback suppression to stop annoying squeals, automatic mixing to balance multiple microphones, and automatic gain control to keep volume consistent as speakers move.

Without a DSP, classrooms often suffer from uneven volume, echo on remote calls and feedback when microphones get too close to speakers. A properly configured DSP solves these issues and dramatically improves speech intelligibility.

GoFutura DSP units are rack-mountable and support analog, Dante/AES67 network audio and RS-232/485 control. They integrate seamlessly with our microphones, amplifiers and speakers for turnkey classroom AV solutions.

Frequently Asked Questions

Common questions about this product and how it fits your project.

What is a DSP in audio?

DSP stands for Digital Signal Processor. It processes audio signals digitally to improve clarity, reduce noise and manage multiple sources.

Does it stop microphone feedback?

Yes. Built-in feedback suppression detects and removes feedback frequencies before they become audible.

How many inputs and outputs does it have?

Models vary from 8x8 to 16x16 or more. Contact us for the right channel count for your project.

Can it be controlled remotely?

Yes. Settings can be managed via PC software, network control and RS-232/485 integration.

Is it compatible with other brands of microphones and speakers?

Yes. Standard analog and Dante/AES67 connectivity allows integration with most professional AV equipment.
