AD149 Film and drama mixer

AD149

The location sound recordist of today demands more facilities and control from a portable mixer. Following years of research the design team that produced some of the most successful portable mixers in the world has created the AD149. It sets a new standard for the twenty-first century by offering a degree of sophistication together with a simplicity of operation never previously encountered in a mixer of its type or size.

Take for granted the functions and qualities that have made Audio Developments famous world-wide for sound quality and ruggedness

Features

Features

- Limiter on each input (adjustable). Release, attack & threshold are set via presets

- Insert point on inputs

- Direct output from each Mic/Line input module

- Three-band equalizer with a choice of four center frequencies in the MF section

- Transformer balanced inputs and outputs (main and auxiliary)

- Two main outputs and two auxiliaries

- Limiter on L & R outputs. Can be linked for stereo operation

- M-S stereo facilities in main and monitor signal paths

- Comprehensive monitor selection

- Two monitor outputs for headphones or speaker amplifiers

- Two communication outputs and one return

- Selection of monitor feeds to communication outputs

- Remote start facility

- Ten pin multiway connectors for output and returns

- Six pin multiway connector for outputs and returns, buffered for use with DAT

- Fifteen way D connector for feeding equipment such as a meter bridge (AD096)

- A pair of meters – either PPM or VU – may be switched to read various outputs or follow the monitor

- Internal oscillator, 1kHz & 10kHz, selectable to L-R and/or auxiliary outputs. Interrupted tone is optional on the left path

- All connectors are presented on one surface of the case and in line with the corresponding module
