The DA series is an upgraded version of SHOW's most successful Public Address amplifiers. Now these devices feature new Class D power technology to reduce heat and power consumption, DSP functionality, all in a single 2U rackmount package. It is a compact, easy, stand-alone and cost-effective solution for paging and broadcasting music in bars, restaurants, shops, offices and small and medium venues. DA-240T and DA-241T have the same features; both models differ in the built-in MP3 player for the DA-241T. There are 4 x Mic / Line inputs, plus 2 x Aux inputs for a stereo source, with volume knobs for instant adjustment. The rear and front panels can be easily set to mute the music while prioritizing the microphone, chimes and siren sounds. Each of the four symmetrical microphone inputs has the possibility to supply the microphone with +24V phantom voltage. For optimized sound quality, the DA series includes a DSP engine digital sound processor. There is also an RS-232 port for remote control of third-party devices. An additional 1 W audio output into an 8 Ω load is available for monitoring functions, and a telephone paging input for remote control of third-party devices can be used for an external priority message. The amplifier is two-channel (stereophonic) with a power of 2 x 240W with a high-voltage output that can be switched to 70 or 100V.

Attention! The manufacturer no longer supports software control of the sound processor using a PC.
