Set of active and passive speaker systems Park Audio L-Set 152 BT

The Park Audio L-Set 152 BT is a professional audio system consisting of one active (L152BT) and one passive (L152) loudspeaker. With a total power of 1400 W and a maximum sound pressure level of 129 dB, the system is ideal for sound reinforcement in large venues both indoors and outdoors.

The frequency range from 46 Hz to 18 kHz provides deep, rich sound with excellent reproduction of both low and high frequencies. The cabinets feature a trapezoidal shape and bass reflex acoustic design. For easy installation, a 35 mm flange for mounting on a stand and six M10 holes on each cabinet are included.

The construction uses high-quality drivers from leading brands: a 15" low-frequency driver with a 3" voice coil from LAVOCE Italiana and a 1" high-frequency driver with a 1.7" voice coil from B&C Speakers. The sound coverage is 90° horizontally and 40° vertically.

The active L152BT speaker is equipped with a built-in Class D amplifier with a nominal power of 2 x 700 W at 4 Ohms. On the rear panel, there are two 1/4" TRS microphone inputs, two RCA line inputs, and two 1/4" TRS line inputs. Separate volume controls are available, and for microphone inputs, there is a three-band equalizer with low, mid, and high-frequency adjustments.

The microphone input sensitivity is 3 mV in MIC mode or 250 mV in LINE mode. The line inputs have a sensitivity of 775 mV (TRS) and 250 mV (RCA). The high signal-to-noise ratio — up to 98 dB for line inputs and up to 94 dB for microphone inputs — ensures clear sound without distortion.

The system supports wireless audio transmission via Bluetooth version 4.1 with a communication range of up to 10 meters in line-of-sight. It supports the A2DP 1.2 profile and SBC and AAC audio codecs.

For stable operation even under heavy loads, forced amplifier cooling is included.
