Download AD149 User Manual
AD149 completes the 140 series of mixers, and has a repertoire of party tricks not to
be found in any other mixer. The design team, as
its starting point, took a list of all the ideas and suggestions presented to Audio Developments over the past
few years.
Since the days of R&D for the AD146, channel insert points have becom de
rigueur. It transpires that many sound engineers have experienced the power of
FLEX-EQ, Audio Development's industrial-strength equaliser, and wish to be able to use it when making
original recordings.

Audio Developments have included circuitry to take full advantage of all M-S
techniques - even shuffling - in both production and post-production.
Customized extruded metalwork developed for the AD140 series creates a robust chassis appreciated by audio professionals. The ergonomically friendly design and construction uses professional components - including Penny & Giles 100mm long stroke, conductive-plastic faders.
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
