Pre or post fader: which tap point to record

Last checked

Every digital mixer takes its recording feed from a point in the channel's signal path: the tap point. Some let you choose it. Where it is decides what ends up in the file. Pick the wrong one and you can record your EQ mistakes, or a silent track because a fader was down.

The short answer. For a multitrack you will mix later, record from the earliest tap: the raw input after the preamp, or just after gain and trim and before EQ. Record post fader only for mixes and buses, not for channel tracks. On an XR18, that means the Input tap on each USB send; on an X32, a Local block on card out.

  • Behringer X32: a Local block (the raw inputs) on card out (X32 tap points)
  • Behringer XR18 or Midas MR18: the Input tap on each USB send (XR18 tap points)
  • Allen & Heath Qu: Qu Classic: the channel Insert Send (the factory default, straight after the preamp). New Qu: the input direct outs, with the Direct Out Source set to the point you want (Qu tap points)
  • Zoom LiveTrak L-12 or L-20: the fixed tap (after the compressor, before the EQ), with the COMP knob at zero (L-12 and L-20 tap points)

Some mixers also offer a "+M" version of a tap, which follows the channel mute: a muted channel then records silence even on an early tap. The XR18 shows these on each USB send.

This page is general recording practice, not a maker's claim. What each mixer calls its tap points, and where they sit, is in that mixer's guide in the mixer recording guides.

The tap points, earliest first

1. The raw input, before the digital trim

Common names

X32 "Local" or "AES50" blocks on the card, Allen & Heath "Post Preamp" and Tie Lines, Avantis Record Send, Mackie "Mic Pre", Yamaha TF "Pre DG", the Soundcraft Ui24R inputs.

  • Pros. Raw and unprocessed. Trim, EQ, mute and fader moves don't touch it. Best for virtual soundcheck, since playback comes back in at the same point.
  • Cons. The preamp gain is still in it: a gain change during the show changes the track level, and a clip at the preamp is permanent. It is before the high-pass filter (HPF), so rumble and handling noise stay in.
  • Use it for a multitrack you will remix later, and for virtual soundcheck. This is the usual default.

2. After gain and trim, before EQ

Common names

X32 "Pre-EQ", Allen & Heath "Post HPF", Yamaha TF "Pre HPF", Soundcraft Signature MTK "post-gain, pre-EQ". The Zoom L-12 sits nearby: after the compressor, before EQ.

  • Pros. Clean tracks, with the digital trim included. A post-HPF version also removes rumble.
  • Cons. Trim moves change the recording. On a post-HPF tap, the HPF setting is in the file for good.
  • Use it for a clean multitrack when the engineer sets level with the trim.

3. After EQ and dynamics, before the fader

Common names

X32 "Pre-Fader", Allen & Heath "Post Comp" or "Post Delay", Behringer WING "POST PROC", Mackie "Ch Direct Out".

  • Pros. Sounds like front of house, so the tracks are ready to use.
  • Cons. EQ and compression are baked in and can't be undone in the mix. A bad compressor setting ruins the take.
  • Use it for quick release-ready recordings and streaming feeds.

4. After the fader

Common names

X32 "Post-Fader", Behringer WING "POST FDR", Yamaha TF "Post ON", Allen & Heath through mix sends.

  • Pros. Follows the show mix exactly.
  • Cons. A fader pulled down or a muted channel gives a silent track. Every fader ride is in the recording.
  • Use it for bus and mix recordings, not for channel tracks.

5. The main mix and buses

Main L/R, aux, groups and matrix outputs: every mixer's "Main LR" or "ST".

  • Pros. A reference mix. A matrix or audience-mic mix is handy for video.
  • Cons. It is the front-of-house balance for that room, so loud stage instruments are often too quiet in it.
  • Use it alongside the channel tracks, as a reference.

What even the raw tap can't avoid

  • Gain changes reach the recording. The earliest digital tap is still after the analog preamp. The X32 manual warns that front-of-house gain changes "can be heard in the recording". Some mixers can lock who changes gain: PreSonus (Preamp Permissions) and the Mackie DL32R (Access Limiting).
  • Digital trim vs analog gain. Where a mixer has both (Allen & Heath, Yamaha "DG" for digital gain, Mackie), the earliest tap is before the digital trim. Allen & Heath says the SQ's Post Preamp point is "affected only by the preamp gain". Set the analog gain for headroom, then ride level with the trim and the fader.
  • Where the HPF sits. The Ui24R inputs, Mackie "Mic Pre", Allen & Heath "Post Preamp" and Yamaha TF "Pre DG" are all before the HPF. If you want the low cut in the file, pick a tap after it.
  • A low channel-count mode sends only a few channels. The X32 card modes 8/8 and 2/2, the XR18's 2 x 2 mode, the smaller WING modes and the "Stereo" stream mode on the Allen & Heath CQ and new Qu all cut what the recorder sees. If a recorder shows only 2 or 8 channels, check this first.
  • Phantom power sits at the preamp and doesn't depend on the tap. Switching it on while recording makes a pop on that track.
  • Shared stage boxes. When two consoles share a stage box, the record feed is after its preamp, so whoever controls the preamp gain changes your recorded level. Allen & Heath Avantis has Gain Tracking to compensate the channel trim, but its Record Send and Tie Lines are before the trim. We found no gain compensation for X32, M32 or WING shared stage boxes.
  • Some mixers have a fixed tap. On the Soundcraft Ui24R, the Signature MTK, the Zoom LiveTrak and USB 1-32 of the Yamaha TF, you can't move the USB tap, except the per-channel point on the TF. For a processed or post-fader version on the Ui24R, Soundcraft says to use an AUX set to POST or POST PROC.

With ShowRecorder

ShowRecorder records whatever the mixer sends to each USB Channel, so the tap point is set on the mixer, not in the app. What the mixer sends over USB has more on tap points in ShowRecorder.

Frequently asked questions

Should I record pre-fader or post-fader?

For channel tracks you will mix later, record pre-fader: from the raw input, or after gain and trim but before EQ. A post-fader tap follows every fader move, and a fader that is down or a muted channel records a silent track. Use post-fader for mixes and buses.

Does changing the gain during the show change my recording?

Yes. Even the earliest tap is after the analog preamp, so a gain change changes the track level, and a clip at the preamp is in the file for good. Trim, EQ and fader moves don't reach the raw input tap.

Which tap is best for virtual soundcheck?

The raw input, before the digital trim. The playback comes back in at the same point, so the channel's trim, EQ and dynamics work on it as they did on the live input.

Should I record pre-EQ or post-EQ?

Pre-EQ, if you want to mix the tracks later: EQ and compression after the tap are baked in and can't be undone. Post-EQ gives tracks that sound like front of house, which suits a quick release or a streaming feed.
