LD Systems IPA424T 4-Channel Hybrid DSP Amplifier 4x 240W
Introducing the LD Systems IPA424T 4-Channel Hybrid DSP Amplifier 4x 240W professional amplifier. LD systems have included Four Channels to operate at 4x 240 Watts. All the outputs on the IPA424T are high-quality toroidal core transformers and operate at 70V/100V.
These transformers are perfect for use with the LD Systems DQOR 3T, DQOR 5T, DQOR 8T speakers. While the low impedance 4-Ohm outputs with the transformer-less operation will guarantee you the highest possible audio quality.
The IPA424T comes packed with versatile functions; including a parametric EQ with a matching speaker library, dynamic tools, a matrix mixer, priority source selection, and delay. Despite this range of functions, the IPA Series power amps are easy to operate. Important functions such as signal, limit, protection, and bridge mode are easily visible via the LEDs on the front panel.
Future-proofing connections
On the back of your IPA424T, you will find a few future-proofing connections. For example, the Ethernet card offers comprehensive configurations and management via software. As the Dante card offers audio networking capabilities to a wide range of Dante-enabled devices. As a result, you can integrate the IPA424T into the Dante network in order to resolve more complex tasks.
Scalability and future-proofing are the biggest advantages of the IPA Series. Its energy efficiency is also ideal thanks to the Class-D technology and switchable auto standby.
Useful installations
In conclusion, good sound belongs everywhere. In the hotel lobby, in conference rooms, in schools, and in houses of worship. Demands are constantly increasing, not only in terms of quality but also in terms of flexibility. Permanently installed and still flexible? This apparent contradiction can be resolved by the IPA Series DSP-based installation amplifiers.
The IPA412T variant with 4 x 120 watts is available for smaller installations.
