I was not aware this kit existed till it arrived this afternoon, it’s a three channel professional audio mixer with three XLR inputs and two XLR outputs.
This mixer from Audio Developments has been designed for a variety of applications. However, its small size (13.5×9.5×4.0cm) and low weight (400gm), lends itself to being mounted on a camera or attached to a belt. It has 3 inputs and two outputs with limiters on microphone inputs and the main outputs. There are two configurations; a one microphone plus two line inputs or three microphone inputs. It is capable of being set and left to process the audio.
MIC INPUTS – One or three electronically balanced type with XLR connector, 48V phantom power, high-pass filter, gain control and mic or line input selection.
LINE INPUT – Instrumentation grade electronically balanced with gain/level control.
ROUTING – Each input is routed to left, right or left and right by two toggle switches.
OUTPUTS – Electronically balanced with XLR type connectors and stereo rotary level control.
Can be unbalanced without loss of level or degradation of quality. A push-button switch selects line or microphone output levels to the XLR connectors. A 3.5mm jack socket carries output signals at microphone level.
LIMITERS – Incorporated in the microphone inputs and the two main outputs. The microphone input limiter is permanently in circuit. A push-button switch introduces the output limiters into circuit and two LEDs indicate the onset of limiting.
LINE-UP OSCILLATOR – 1kHz tone injected into outputs.
MONITORING – Headphone output on 3.5mm jack socket with a push-button switch selecting the direct or return signals. The return signals are brought in on a 3.5mm stereo jack.
METERING – Two LED ladders indicate output level
POWERING – Either external power, via a 4 pin Hirose connector, or a separate PP3 9V battery pack can be used to power the mixer. An LED indicates power present and flashes when the voltage is too low.
HDW : The AD 071 is a very hi-spec British made audio mixer capable of producing high quality sound mixes with toggle switches for line/mic inputs on all three channels, this would be a good mixer for ENG work and would make a hi end mixer for the DSLR market.
