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
– 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
