Channel Strip

  1. 1. -SAMHITA SHILEDAR
  2. 2. I’m Samhita Shiledar from India! I recently completed my Chemical engineering and working in same field now. I play piano and sing Indian Classical Music. This lesson is for week 3 of Introduction To Music Production at Coursera.org My ppt is about Channel Strips. ‘Channel strip: Teach the signal flow through a channel strip in a DAW or analog mixing board, describe in detail every component of the channel strip including its usage and position in the signal flow. ’ Hope you guys enjoy ;)
  3. 3. Specifications  In my presentation, I will be explaining channel strip in the analogue desk AUDIENT ASP 8024
  4. 4. WHAT IS CHANNEL STRIP?  CHANNEL STRIP allows the output of an audio device to be amplified by a line level and integrated into some other systems as well  Set of controls for each sound mixer channel makes up what called the channel strip.  The channel strip contains a lot of information, and the visual position of the various functions often doesn’t correspond with the actual flow of the signal.
  5. 5. Input Section Mic Pre Amp Insert Aux Send EQ PAN MUTE/SOLO Volume faders
  6. 6. INPUT SECTION Input section is divided into three parts: 1. Channel Path 2. Tape return path 3. Mic/ line and tape returns signal section We have an XLR input for mic input, and we have a line input for a line level source.
  7. 7. Channel Path Channel Path: Deals with the recording signal The meter swap (MTR) switch allows you to display mic/line signals coming into the desk on 20 segment meter. Tape input signal would be then displayed on smaller 3 segment meter Preamplifier allows you to use the Mic/line signal into the desk.
  8. 8.  Press the Mic/line switch to select the input.  Phantom power switch is ON for condenser microphones. Always remember to reduce the gain of speakers while turning phantom power on. And similarly while disconnecting
  9. 9.  Phase reverse switch is situated on the channel path. It reverses the phase of signal being recorded and not the signal coming back from our recording device  High pass filter can be used to get rid of any low frequency
  10. 10. Insert on tape return path Insert on Channel path  Insert points are used to place dynamic processing such as a compressor into a path. It places into the recording path. This means that output from your processing device would be recorded and can not be undone. Thus if you are unsure of processes, you can insert on tape return path. Here settings are applied after the track is being recorded.  The insert points are a convenient way to bypass a process without having to find bypass button on unit itself.
  11. 11. Tape return path Tape return path: Deals with the signal after being recorded Tape trim: Tape input has a trim control of plus minus 15dB. This allows you to trim levels which have been recorded too hard. You should always aim to get good signal to noise ratio on your recording device. Else tape trim is used.
  12. 12. Mic/ line and tape returns signal section  Mic/ line and tape returns signal section 3 segment meter 20 segment meter  Measures the signal when it is recorded and after it is being recorded.  20 segment meter shows the tape input signal. It is the return signal from the device into the desk after it is being recorded  3 segment meter gives the indication of the mic line signal coming into the desk
  13. 13. Mic Preamp This is going to be our input level. We can use this to set levels, just like you do on your audio interface when recording.
  14. 14. Signal metering A 20 segment peak reading led bargraph provides channel metering in the long fader path, and a 3 segment led bargraph indicating signal present, normal level, and overload, in the short fader path. The meter functions can be reversed if required.
  15. 15. Inserts for channel paths Both the mic/line path and monitor/mix paths have their own balanced inserts with individual “insert in” switches.
  16. 16.  Multitrack Buses: Multitrack buses are assigned via 12 individual switches in combination with a shift button allowing access to buses 13-24. The assignment section can be accessed from either the short or long fader paths, pre or post pan.
  17. 17. Auxillary Master Section  Control overall level of aux outputs. A balanced or mixed bus can be created by using controls on the channel strip.  Overall created by auxillary master controls Auxiliary sends Mute
  18. 18. Auxiliary Buses
  19. 19.  Auxiliary Buses: A total of 14 Auxiliary send buses can be accessed via 8 controls. Controls 1 to 6 can be reassigned to buses 7 to 12, and are switched in pairs to the short fader path and also pre / post the relevant fader. This leaves 2 controls permanently assigned to Auxiliary A and B buses, individually switched to the short fader path. These are normally used for artists foldback purposes, although they can be switched post fader if required for extra sends
  20. 20. A flexible Auxiliary bus combining facility on the Master module allows the 2 independent signals within a channel to access the same Effects device. Should extra sends be needed a single button push will allow the short fader to become a post long fader send accessing the 24 track assignment buses, with or without panning. This flexibility and more, is achieved clearly and simply by having consistently positioned and labelled controls, together with informative backlit indication of which signal source is in which signal path.
  21. 21. EQ Section  Equalisers: During the mix phase the short fader path is often used to provide extra inputs to the mix, any or all of which may require EQ and Effects processing.  EQ section:  Equalisers are what would be referred to as tone controls.  EQ is mainly associated with long fader signal path.  IN switch places the equalizer in circuit.  SF switch places the equalizer into short fader signal path.  Aim is to treat the signal before it is recorded.
  22. 22. EQ IN SF Switch Shelving EQ Parametric EQ
  23. 23.  EQ is split into two parts: 1.Shelving EQ: Has high frequency boost / cuts at 10kHz to 18 kHz Low frequency boost or cuts at 50Hz and 100 Hz 2.Parametric EQ Has high frequency boost cuts and low frequency boost cuts  Frequency Sweep: Controls the centre frequency of high mid and low mid EQ.  Q factor: adjust the width of the frequency to be attenuated
  24. 24. HF boost/cut 10kHz to 18 kHz switch LF boost/cut 50Hz and 100 Hz switch HMF boost/cut LMF boost/cut
  25. 25. Frequency sweep Q factor
  26. 26. Routing section  It is situated directly below the input section of each channel.  While recording, this allows us to route the channel path to the recording device.
  27. 27. Short fader controls  Short fader controls: Fader, mix, pan, cut, solo and long fader link controls for the short fader path.
  28. 28. Long fader controls  Fader, mix, pan, cut, solo and fader flip for the long fader path.  Normally the tape return signal, that is the signal coming back from your device is fed to the long fader signal path.  When flip switch is pressed, it will feed the short fader signal path. Long fader will then become the channel path input.
