Switchable input attenuation
A three-position input attenuator switch allows you to set the the AR133's Impedance (Pad setting) to 1MOhm (0dB), 47kOhm (20dB), 47kOhm (40dB)
Matches the level and impedance with unity gainwithout loading the source
Interfacing additional equipment such as DJ mixers with the house console and PA may cause level and connector difficulties. Connect the DJ mixer to either the jack or XLR input of the AR-133 (this will depend on the interface cables to hand which match the output of the DJ mixer) and then the AR-133's output XLR to the house console.
Can drive signals up long cable lengths
A DI box converts the high-impedance of an instrument to a balanced low impedance signal. This enables the instrument signal to travel distances of 100 meters (300 feet) without adding appreciable noise.
Powered from console phantom power or internal battery
The AR-133 can work reliably on a wide range of phantom power voltages, although of course the typical supply provided by modern consoles is +48 volts. The AR-133 accepts supply voltages of +48 volts down to +20 volts without loss in performance.
Automatic switchover to battery if phantom powerfails
While the AR-133 is receiving good phantom power, the power LED is lit continuously. Should the supply fail for any reason, the AR-133 will switch over automatically to run from the internal battery (as long as one is fitted!). Under these conditions, the power LED flashes approximately every 2 seconds.
Parallel Link Jack output to feed amplifiers directly
The AR-133 has a parallel feed from the input connector so that the instrument may be simultaneously connected to the AR-133 and the amplifier. This means that no special splitter cables are needed.
