Digital Class-D Single Channel Power Amplifier

Overview

The digital class-D power amplifier in the Technitia TA Series range uses switching power technology, which has minimal power consumption and efficiency levels up to 85%. In addition, it reduces heat production, which helps to increase the performance life of the amplifier.

The Technitia TA Series can be used as a digital public address system at a low cost because of its 120W to 500watt rated power output. The adaptable loudspeaker outputs, which come in high impedance 100V and low impedance 4-16 ohms, allow it to be used for both fixed installations of PA systems and installations of hi-fi stereo systems. There is only one balanced input with gain control on the Phoenix connector. Speaker outputs might be 4-16 ohms or 100V. The dip switch pre-setting could be used to enable or disable the built-in high-pass filters. Automatic standby is enabled after a minute of no signal input detection, and it awakens right away on any input. Protection, clip, input, and output are all visual working state indicators for simple oversight. full overload, high temperature, clip, short circuit, and DC protection. Switchable AC power supply from 115V to 230V allows for the installation of sound systems anywhere in the world.

Technitia Professional Amplifier with Dante

Key Features

The latest Technitia Professional class-D Amplifier design has low distortion and high efficiency.
4.3-inch IPS capacitive touch screen; display device status: mains voltage/current/amplifier status, amplifier temperature, output mode, amplifier real-time voltage/current/power, channel volume, and speaker impedance, which can be viewed and controlled by switching menus on the panel touch screen
Switched power supply, with high efficiency; soft starter can prevent absorbing large currents into the power grid when starting up and interfering with other electrical devices.

Constant voltage and constant resistance: 100V, 70V, 16Ω, 8Ω, 4Ω
Effectively suppress power harmonics, and meet the EU green power standard.
Intelligent peak clipper controls the power module and speaker system to work within a safe range.
Standard XLR + TRS1/4″ composite input interface, simple interface design is more convenient for different use
Suitable for different places, stereo mode or bridge mode is optional.
Grounded input pin and suspension control switch.
High-performance 32-bit floating-point DSP chip processor, 96KHz sampling rate, 24-bit A/D
ARM operating system works with a 4-inch touch screen.
User-friendly PC software supports multiple simultaneous controls.
Each output channel supports 8-band parameter equalization, electronic frequency division, delay, limiter, gain, polarity and other functions.
It can be connected to the computer through USB/RJ45 interface.
With overvoltage protection, under-voltage protection, over-temperature protection, over-current protection, DC protection, output short circuit protection, temperature control fan, etc.
Support DANTE network transmission protocol, low-latency DANTE network audio transmission, 4 sending/receiving channels, network audio extender
Network TCP/IP control can realize the management of multiple devices, and the network interface can be cascaded; USB, RS485 support external protocol control
Support free switching of various input sources: analog input, AES3 digital audio input, Dante network audio input. The analog audio interface can be cascaded

Panel handle.
USB connection interface: reserved protocol connection interface.
4.3-inch IPS capacitive touch screen.
Power switch: When the device is powered on, press and hold this button for 2 seconds to switch between standby and power-on status.
Power indicator: blue: power on; orange: standby.
Gain adjustment knob and selection button: slow rotation for 0.1dB adjustment; fast rotation for 1-5dB adjustment; no adjustment is made when the rotation speed is slow to a certain extent; press the knob to switch between channel mute and normal playback

AC input power cable
AC power switch: ON; OFF
Amplifier output channel 1, 2 (Spoken)
Bridge interface mode (CH1)
Air outlet
Input channel A/B/C/D, channel A and channel C support AES3 digital audio input.
LINK OUT: parallel with the input
Control and Dante transmission interface (hand-in-hand): connect PC software and Dante audio transmission; PRI is the main network port, SEC is the secondary network port, which can be used for cascade of multiple devices.
GPIO interface (reserved control interface); RS485 interface: used to connect PC software and central control.
Power amplifier output channel 3 and 4 (Spoken).
Bridge interface method (CH3)
