AD 071


  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 limiterson microphone inputs and the main outputs. There are two configurations; a one microphone plus two line inputs orthree microphone inputs. It is capable of being set andleft to process the audio.

Features

 

• 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.
