Thanks to these solutions, the system produces stable sound at both low and very high levels, while the automatic adjustment of bass and treble allows you to precisely tailor the tone to the user's preferences.

The speaker houses a two-channel digital amplifier, which produces an impressive continuous power of 600 Watts RMS. Combined with the highly efficient high and low-frequency drivers, the entire set can achieve a maximum sound pressure of up to 125 dB SPL.

The signal distribution to individual speakers is done with a two-way crossover, which transmits the high-frequency signal to a 1.76" horn tweeter with a compression chamber, while the mid and low frequencies are transmitted to a 15" woofer with a paper cone texture. The tweeter features a 44 mm coil and a 4.8-inch ferrite magnet, while the mid-bass driver features a 75 mm coil and a 6.8-inch magnet, also made of ferrite. Both speakers have an impedance of 8 Ohms. The appropriate configuration of the individual components and their precise tuning ensures a wide bandwidth for the entire set, ranging from 45 Hz – 20 KHz.

The built-in Bluetooth unit allows you to play music files wirelessly from various compatible portable audio sources using the A2DP profile. This enables you to play your favorite songs stored in your smartphone's library at an excellent volume level while enjoying incredible sound quality!

In addition to wireless audio transmission, the device also includes a player compatible with all types of USB storage media with a maximum capacity of 32 GB. This provides hours of audio playback without using a smartphone, which can then be used for other purposes. The player also allows you to play files using the most common MP3 and WMA formats. There are also various types of inputs available on the back of the enclosure for signals sent from external audio sources. The PA1500PRO device is equipped with balanced female XLR and 6.3 mm jacks, as well as a second balanced female XLR jack and RCA input. This facilitates the direct connection of a mixing console or microphone, a keyboard or an electric/acoustic guitar, a portable audio player, or a CD player. Each of these inputs has an independent input level control. The speaker features a balanced XLR output jack and a 6.3 mm jack, both of which provide full-range audio transmission to, for example, a second speaker of the same type. It is the ideal solution for producing even greater power and creating stunning stereo effects.

The entire device is housed in a bass-reflex type solid wood enclosure, in 15 mm plywood, reinforced with screwed connections.

There is a display on the rear panel that shows basic information about the selected audio source for more comfortable operation. The side walls have profiled handles for easy handling. The speaker can be placed directly on the floor, on a suitable table, as well as on a professional tripod, as the bottom of the enclosure has a standard tripod socket.

The professional PA1500PRO sound system from Blaupunkt is a product designed to meet the expectations of users who appreciate excellent sound quality, even in the most challenging conditions.
