A 4260A • Compact 100V Class H Bluetooth PA Mixer Amplifier 120W

Compact class-H amplifier design with in-built music source thanks to a USB/SD module with wireless Bluetooth audio streaming.

SKU: A 4260A Categories: ,
Overview
These compact Class-H design amplifiers offer multi source mixing plus USB/SD card/FM tuner audio playback and Bluetooth streaming functionality. They are an all in one amplifier and audio source housed in just a single rack unit of space! Ideal for use in retail, offices, venues and other commercial buildings. Dimensions: 484×295×44mm

The unique feature of the Class-H design is the significant reduction in power consumption and heat generation due to the switchmode power supply design employed. They utilise active power factor correction (APFC) switch mode power technology allowing an efficiency rating of 85%. The result of which is a much cooler running amplifier (<55°C), offering a long life span and significant power savings for a reduced environmental impact.

Screw terminal connections are provides for balanced inputs from sources, 70/100V output and 24V DC input. A stereo RCA line output is provided, plus two stereo RCA line inputs. Easy line/mic/phantom power options are available on mic inputs 1 to 4. A top priority emergency input is also provided which can be connected to an alert/evac tone generator.
