The document discusses audio consoles and their components and functions. An audio console combines and balances incoming audio signals and routes them to outputs. Key sections include inputs, outputs, monitors, and a mixer section. Analog consoles are described as having lower costs but easier operation than digital consoles, which provide features like automatic feedback suppression and noise resistance. The signal flow through a typical analog console channel strip is explained, covering components like the input section with trim knobs and pads, auxiliary sends, routing, channel faders, and equalization. Meter types like VU and peak are also defined. Finally, the Soundcraft Vi7000 digital console is briefly described.

2. Audio Console
 An audio console combines, balances and roots the
signal.
 A simple console combines several of the
incoming signals into a single output signal.

3. Mixer and Console
 The terms mixer and console are often used
interchangeably.
 However , a mixer is a small portable device
performing limiting functions while a console is a
complex device performing larger processing
functions.

4. Console Sections
 Input- Allows signals from input sources
such as microphones & line level devices.
 Output-Allows signals to be sent to recording
devices & signal processors.
 Monitor-Allows the signals to listened to. For
example: main mix, headphone mix, effects
send mix etc.

5. Analog vs Digital Consoles
 The basic difference is the way sound is
processed.
 Digital consoles have gained a great hold due
to their convenience and resistance.

6. Digital Console features
 Settings can be pre programmed and recalled
when necessary.
 Mixing and processing feature that only digital
can provide like automatic feedback
suppression.
 Noise resistant digital transmission.

7. Analog Console features
 Lower cost for a limited set of features.
 Easy operation for first time users.
 Provides conventional approach

10. Input Section
 Microphone-line input selector controls which signal source
enters the input section.
 Phantom power -Just ahead of the microphone preamplifier
is the phantom power supply ( 48 volts DC).
 Trim/Gain Knob -The trim is a gain control that controls the
nominal input levels of various input sources.
 Pad -reduces the power of a signal. It is used when the trim,
by itself, cannot prevent overload in the mic signal.

11. Insert Section
 High-end production consoles usually include a
inserts/dynamics section after each I/0 module for
added signal processing
 It often includes compression, limiting, and noise
gating.

12. Auxiliary Sends Section
 The aux (auxiliary) send control (also called effects
[EFX or FX} send, reverb send, or echo send) feeds the
input signal to an external (outboard) signal processor,
such as a reverberation unit, compressor, or
harmonizer.

13. Routing Section
 Track Routing Switches: The switches route the
channel path signal to the multi track machine, and it
is possible to route a signal to more than one track.
 Channel pan switch: used for panning channel
signals between odd and even tracks of the multi
track in conjunction with the routing switches.
 Odd/Even/Both switch: This switch will determine
whether the signal is sent to the odd channel only,
the even channel only or both

14. Channel Faders
 The channel and monitor faders control the channel
level of the signal being recorded and its monitor
level, respectively.
 During recording channel levels to the multi track
recorder are set for optimal signal to-noise ratio.

15. Other Sections
 Master section includes-master buses,
master fader, aux (or effects) send, aux (or
effects) return, and meters
 Monitor section includes-Speakers volume,
recorder select, send, mix, loudspeaker
select, and mono switches.
 Communications section includes-talkback,
slate/talkback, and oscillator.
 Equalization Section-HF, MID1, MID2, LF,
Peaking/Shelving or Bell, ‘Q’

16. Meters Types
 VU- Volume Unit- Useful in balancing levels.
Similar levels sound similar to the ear.
 Peak- Useful for monitoring recording levels,
especially digital when the absolute maximum
level must be known.

17. Soundcraft Vi7000
 The latest Vistonics™ & FaderGlow™ interface
 Up to 128 inputs and 32 mono/stereo busses
 Enhanced audio processing with 96kHz sample
rate option
 Powerful new features including BSS
DPR901ii™ Dynamic EQ
 New Local Rack hardware for 384 I/O channels
 128 channel record interface via MADI or Dante™
