Audio Developments AD162(便携式3入2出ENG混音台
This is the first Audio Developments mixer designed with an LCD meter in place of the traditional analogue type, creating the opportunity to fit a significant number of facilities into a much smaller space. The mixer, while having all the attributes of the AD161 ( its mono counterpart), is only 25 per cent greater by volume. The meter shows not only the output levels in PPM or VU format, but gives an indication of the battery condition and monitor status. (Whether listening to direct or return signals). Using internal DIL switches the meter can follow the monitor selector. This gives the operator the opportunity to show the return level. The mixer has been designed to introduce to the market a high quality, yet affordable, stereo ENG mixer with the durability to last well into the next decade.
- MIC INPUTS - Three electronically balanced type with XLR connector, High Pass Filter, 6 position Input Gain Selector, rotary level control, 48V Phantom/12V T (AB) Powering.
- MIC/LINE - Each input is switchable to line level giving the same degree of control as for mic input.
- ROUTEING - Each input routed to left or right output using a centre detent panoramic potentiometer.
- OUTPUT - Transformer balanced with XLR Type connector, rotary stereo level control.
- 10 PIN MULTIWAY CONNECTOR - Contains left and right main output signals and left and right return signals to the monitor path. This allows a single connection to the recording media, e.g. Cameras. It can be used simultaneously with the XLR outputs.
- LIMITER - Incorporated in the main outputs. A push switch introduces the limiter into circuit and a further switch enabling left and right signal paths to be linked. Two LEDs indicate the onset of limiting.
- LINE UP OSCILLATOR - 1k Tone into Output
- TALKBACK/SLATE - An internal electret microphone allows a 'slate' signal to be added to the main outputs and a TALK switch enables communication to a third party on a separate monitor output
- MONITORING - Headphones on Type A Jack with rotary switch to select pre-fade input, main output: left or right only or stereo. Three push buttons operate in conjunction with the rotary switch. MONO enables the monitor signal to be converted from stereo to monarual; RET allows the return signal to be monitored in the format selected by the rotary switch; MTX decodes an M-S signal to the L-R domain and visa-versa. A second monitor output allows a third party to receive a monitor feed, which also includes a private line (TALK) facility. This second monitor can be configured, using internal DIL switches, to receive inputs 1 or 2 or both, giving the opportunity to send the boom operator his/her own signal if they are the receiver.
- METERING - LCD type giving indication of left and right output levels, battery status and direct/return monitor selection. A back-light facility assists use in low ambient light levels.
- POWERING - Internal batteries using 6 x AA cells or an external supply with a source voltage 9V to 15V DC. A LED indicates the mixer is ON and also flashes when battery level is low. A small 4 pin connector enables other external equipment, such as radio microphone receivers to be powered.
