19 Inch Rack Mount 4 Zone Stereo Amplifier 400 Watts With Speaker Selector Volume Control

Professional 4 Multi-Zone Stereo Amplifier 19 inch Rack Mount Powerful Amp 400 Watts with Speaker Selector Volume Control

In the past, the world distinguished between multichannel and multizone.
Multichannel means to have one audio source in multiple channels with the same power in one amplifier.
Multizone means controlling several zones in one amp with different sources and settings for each zone.
But now there is no more need to differentiate between multizone and multichannel since there are multi channel amplifiers that can control, patch, and set up each channel individually.

The multi channel power amplifier can be used at home or for commercial applications.

For instance, retail units and restaurants but not always for residential audio systems where typically a much greater degree of control is required. For example,

different volume levels in different rooms, turning rooms on and off remotely and/ or allowing different audio sources to be played in different rooms simultaneously.

Features of the 4 zones stereo power amplifier

*The Vistron Audio 8 Channel hifi Home theater amplifier is Perfect for Your Home Entertainment system;

* High performance amplifier, a slim cabinet but providing powerful output

*The power amplifier with 8 channels and 4 zones

*50W / channel at 4 ohm

*Bridge mode 150W RMS / channel at 8 ohm

*RESIDENTIAL and COMMERCIAL power amplifier

*Custom installation amplifier for home theater systems

*Includes front-panel status indicators and slim form factor that is 2U rack-mountable (hardware rack mount included)

*CLASS D EFFICIENCY: Uses Class D amplifier technology for low distortion and higher efficiency and special protection circuitry safeguards from thermal overload and short circuits.

*Versatile Easy Connection to Any System, Each zone of the amplifier has individual volume adjustment for the left and right channels, giving you precise control over your system.

*Multiple Auto Power-On/Off and Trigger Option

*8-CHANNEL HIGH POWER AMPLIFIER: 100w per channel deliver high power performance with 5-way speaker binding posts (Banana Plug) outputs, pass-through output for external amplifier linking (Daisy-Chaining) & integrated 4-channel bridgeable switches

The Zone 12V Trigger In is used to activate a specific zone. The Zone Trigger Out can be used to trigger other 12V devices.

*Bus Input with Individual Channel Input Options

this amplifiers offer a global bus input with a loop output as well as channel-specific inputs Installers have the option to use the amps as a standard amplifier, taking one stereo input signal and distributing it to up to 4 stereo zones of audio, but they also have the option of using each amplifier channel individually.

*Individual Channel Gain Controls

Each channel of the amplifiers can be adjusted with its own gain control, allowing fine tuning for the particular source, or for the particular audio zone to adjust the sound level to match the space’s needs
