AK-8800A Smart Audio Management Power Amplifier


● This audio management power amplifier is mainly aimed at engineering applications such as high-quality classroom recording and broadcasting, multimedia classroom recording and broadcasting, court recording and broadcasting, interrogation room recording and broadcasting, local and remote conference recording and broadcasting, and specially develops all-round audio processing products for the needs of audio collection and on-site sound reinforcement; ● Special research and development are carried out according to the actual application requirements of recording and broadcasting system engineering. Modular design is adopted. Corresponding module combinations can be selected according to different engineering needs to provide the most suitable application scheme for engineering needs and save engineering input; ● In order to meet the diverse requirements of recording and broadcasting system applications, the management power amplifier has designed various interfaces and settings that are rich, comprehensive and adjustable, which can derive a variety of matching effects and can easily cope with various requirements. At the same time, it also effectively avoids the dependence of the system platform on other audio intermediary adjustment equipment and has high system integration; ● 10 microphone balanced input (Phoenix plug),1 to 4 microphones are divided into area A, 5 to 8 microphones are divided into area B; ● 2-channel acquisition microphone, independent lotus output interface, without entering any adjustment of the machine, can be directly connected to the recording and broadcasting room for recording and broadcasting sampling; ● Independent microphone volume adjustment, independent 48V power switch; ● A. B two-zone microphone can choose 4-for -1 function, which can directly pass through 4-for -1 function; A. B two-zone microphone independent active environmental noise cancellation module, A. B two-zone independent threshold debugging, LINE input RCA interface, independent volume control (enter feedback function); ● AUX input RCA interface, independent volume control (no feedback function), microphone input impedance: 47K,LINE input RAC input impedance: 10K,RAC recording output impedance: 1K,RAC system output interface impedance: 220 ohms, system expansion output interface, 2 RAC interfaces, volume adjustment output level; ● A. B two-zone acquisition system signals independently output RAC recording interface, independent volume control, A. B two-zone microphone signals professional mixed Senior high school low tone adjustment, professional digital feedback suppression module, through/feedback mode convertible; Recording, Bluetooth, recording playback, USB, SD playback function module, 4X150W/8 ohm stereo power amplifier output, which can be bridged into 2X250W/8 ohm 2 channel output; ● One-key panel control feedback suppression and independent volume of 4-channel power amplifier, independent 4-channel level indicator light, professional frequency display screen, monitoring output level at a glance; ● Full Chinese operation interface, easy to understand.
