Description car amplifier Cadence QR 80.3
The main advantages of the mechanism
The high-performance three-channel sound amplifier Cadence QR 80.3 is made for installation in various types of automobile transport. One of the features of his work is a reduced level of energy consumption. Due to its compact dimensions (length — 310 mm, width — 160 mm, height — 52 mm), the installation process will not cause any difficulties, even in hard-to-reach places. A sound amplifier can improve sound quality by minimizing distortion at high volume. At the same time, using such an amplifier, you can increase the input signal to the required level. The case is made of high quality materials, which provide excellent indicators of mechanical strength.
Technical specifications
This model is a Class D (digital) amplifier, which guarantees excellent sound. A stylish accessory to add clarity to your speaker system and provide comfort and enjoyment of listening to music. When connected with a resistance of 2 ohms, you can send 80 watts to the speakers, and the subwoofer channel with a resistance of 2 ohms reaches 400 watts of power. It must be borne in mind that high-quality sound will be in that speaker system in which the input impedance is equivalent to the resistance of the amplifier itself. The frequency range ranges from 20 to 30,000 Hz. The ratio of noise to signal is 90 dB.
Reliable performance and stylish design
Cadence QR 80.3 is a universal mechanism that impresses with its stylish design. A beautiful matte silver color case meets many of the requirements of users who choose the best devices to improve the sound source.
