Audio Developments AD 071

What is it?A compact mixer suitable for mounting on a camera or a belt. DetailsThe AD 071 combines small size (13.5 x 9.5 x 4.0cm) and low weight (400gm). It features three inputs and two outputs – with limiters on the mic inputs and the main outputs – and is available in two configurations: one microphone plus two line inputs or three microphone inputs. Each channel incorporates an electronically balanced input with XLR connectors and 48V phantom power plus high-pass filters, gain controls and mic/line input selection. Each input is routed to left, right or left and right by dual toggle switches. Outputs are also electronically balanced with XLR connectors and a stereo rotary level control, but can also be used unbalanced without loss of level or degradation of signal quality. A push-button switches line or microphone output levels to the XLR connectors while a further 3.5mm jack carries output signals at microphone level. Other features include LED ladder monitoring of output level, a 1kHz line-up oscillator and a headphone output (on 3.5mm jack). The AD 071 can be either externally power, via a 4-pin Hirose connector, or from a separate PP3 9V battery pack. An LED indicates power present and flashes when the voltage is too low.
