Extra Information Features:
-Low noise microphone amplifier with powering for 48V Phantom and 12V Tonader (TA) powering.
-6 to 12 input frame, mic or line selection.
-A simple, but effective, three band equaliser, proved and approved under field conditions, in use throughout the AD140 Series of mixers.
-Inputs are balanced and protected against radio-frequency interference. A continuously variable high-pass-filter protects against low-frequency saturation.
-The main stereo output is transformer balanced and has separate left and right fader control.
-Two auxiliary outputs are transformer balanced and have separate master rotary controls. Auxiliary 1 & 2 are routed from each input using a 3 position switch (off, pre & post
fader).
-Auxiliary 2 has a rotary level control on each input.
-A mono output of the left and right signals is also transformer balanced.
-Direct outputs from each input channel are unbalanced using a very low output impedance drive amplifier enabling high drive capability and minimising line interference.
-Limiters are incorporated on both the inputs and outputs. The main output limiter can be linked for stereo operation. LEDs indicate limiting action.
-Two LCD meters display – either PPM or VU – main output, auxiliary output and PFL levels of each input. Useful for monitoring level at a direct output. Battery level and monitor status (Direct or Return) are also indicated. Back-light illumination is also included.
-Internal oscillator at either 1kHz or 10kHz frequency. The oscillator signal replaces the signal on the output when selected.
-An internal microphone enables the mixer operator to communicate with the main output (SLATE), with each auxiliary and an external outstation (EXT). The outstation (Private Line) receives a monitor signal, selected using a series of push-button switches.
-The headphone monitor may be switched between main output, auxiliary outputs and returns. PFL overrides the selected monitor signal. Monitor selection allows left, right, left/right, auxiliary 1, auxiliary 2, auxiliary 1 + 2 and returns to be routed to the headphone output. An M-S matrix amplifier can be inserted to main or auxiliary outputs in the M-S domain.
-An electronically balanced stereo tape return appears on a pair of jack sockets on the connector panel.
-All inputs and outputs are presented on one surface of the case. The inputs, main output and direct outputs are on XLRs. Auxiliary outputs, returns and headphone output are on Ľ inch jack sockets.
-The mixer can be powered from an internally fitted battery box (8 x C cells) or an external DC source (12V to 15V DC). |
