USB WALKTHROUGH – LV14

PLAYBACK & RECORDING VIA USB
The LV14 is a fully ASIO (Windows) and Core Audio (MAC) compliant audio interface and as such does not require any special driver installation.

Playback

1. Make sure the LV14 is set as the audio output device within the PC’s system settings and within the DAW software or audio player
2. Start audio playback from the DAW or audio player
3. Press the USB ROUTING TO CH 11112 BUTTON 36 on the LV14
4. Make sure the LV14’s MON SEND to PHONES I CTRL RM button 31 is in the up position
5. Slowly bring up the CH 11 112 level control

Recording:

1. Connect all input signals to the LV 14
2. Set the channel level controls and MAIN level fader so that the MAIN level meters show the mix peaking somewhere around 0 dB
3. Make sure the LV14 is selected as the audio input device within the PC’s system settings and within the DAW software
4. Arm the stereo DAW track and press record. The LV14’s MAIN MIX will now be recorded by the DAW
   NOTE: The LV14’s stereo MAIN mix output signal is the default signal feeding the USB audio output and being sent to the DAW Playback audio from the DAW will come into the LV14’s CH 11112 when the USB ROUT/NG TO CHll 112 button 36 is engaged.

Overdubbing

1. Make sure the LV14 is set as the audio input and output device within the PC’s system settings and within the DAW software
2. Reduce the LV14’s CH 11112 level control to its minimum / full counter-clockwise position (do this for any channels you do not want recorded by the DAW)
3. Bring up the channel level controls for the channels you are about to record and set the MAIN level fader so the MAIN level meters peak somewhere around 0db. Any signal panned hard-left will be sent out the left channel only, any channel panned hard-right will be sent out the right channel only
4. Press the MON SEND to PHONES I CONTROL ROOM button 31 and use the channel MON SEND CONTROLS 19 to create a mix of the playback and live recording tracks. You will hear both the playback tracks and the signals you are recording, in the Headphones and CTRL RM OUTS, but only the signals being sent to the MAIN mix will be recorded by the DAW
5. Within the DAW, you will have the option to record a mono signal (LV14 1/L only or LV14 2/R only) or a stereo signal (LV14 1/L + LV14 2/R). Select the appropriate input within the DAW. Arm the DAW track and hit record.

A REAL-WORLD EXAMPLE

Tracking a Vocal and a Guitar simultaneously to a click track being generated by your DAW.

1. Plug your vocal mic into XLR or TRS input of CH 1 (activating the 48V Phantom Power switch if it is a condenser mic)
2. Adjust GAIN and CH volume to get an acceptable level in the MAIN OUTPUT VU meters (aim for the last green light, just before the lights turn orange)
3. Then turn the PAN control all the way to the left
4. Then Plug in your guitar to CH6 with the Hi-Z button pressed (again getting a good level by aiming to light up the last green light on the VU meter with your signal, just before the lights turn orange)
5. Now turn the Pan control on CH6 all the way to the right
6. Your DAW or audio capture software can now receive audio from the LV14 USB onto two separate incoming tracks using the L and R sides of the LV14 MAIN OUTS, as 2 independent audio signals containing your vocal and guitar (each have been panned completely to the left and right and so are now isolated from each other)
7. Now in your DAW set up a channel that can play a click or guide track you want to record along to but do not start playing it yet
8. Then set up your DAW’s audio output to the LV14 USB and press the USB Routing to CH 11112 button e
9. Press the MON SEND to PHONES I CONTROL ROOM button ED
10. Make sure the CH 11112 level control is turned all the way down to the left (counter-clockwise) and slowly turn up the MON level control on CH 11112.
11. Use the channel MON SEND CONTROLS 4=) to create a mix of the playback and live recording tracks. You will hear both the playback tracks and the signals you are recording in the Headphones and CTRL RM OUT output, but only the signals being sent to the MAIN mix will be recorded by the DAW
12. Now when you arm a channel and hit record in your DAW you will send your click or guide track audio to the LV14 for you to monitor on your headphones, but your final captured performance will not include these signals. Only your performance will be captured via USB into your DAW

APPENDIX

MICROPHONE INPUT (MIC)

This XLR combo connector will accept virtually any professional microphone. It is designed for microphone and line level signals on either XLR or ¼” cables.
Some microphones, mostly condenser mies, need phantom power to operate. Switch on 48V phantom power. If you’re unsure if your mic needs phantom power, check the instructions or the manufacturer’s website for information. Phantom power should not hurt most microphones, except for very old or damaged ribbon microphones.
For live microphone use {where the microphone signal is amplified through a PA system} engaging the HPF {high-pass filter) is recommended for reducing “boominess” and maintaining clarity in the microphone signal.
Use the microphone preamp’s gain control {explained below) to bring the microphone up to a high enough level to use with the mixer.

LINE INPUT (LINE)
This ¼” input is designed for line-level signals. It accepts either balanced (TRS) or unbalanced (TS) cables. The level of this input is also controlled by the gain control, explained below.
Do not use both the microphone and line inputs on the same channel.
The mixer will distort and the noise level will go up.
The line input is not designed to accept an instrument-level signal, such as the output from an electric or acoustic guitar or bass. If you want to plug your instrument into the mixer, we suggest a direct box (also called a DI box). Plug your instrument into the direct box, then plug the output of the direct box into the microphone input of the mixer.

GUITAR/BASS
Passive guitar or bass signals tend to have the best sound and sensitivity when they are connected to a high-impedance input (similar to what you would find on a guitar or bass amp). When connecting a passive guitar or bass signal to CH 314, engaging the GUITAR HI-Z switch is recommended. It is possible to connect 2 guitar signals to CH 314 simultaneously. When both inputs are used, the signals will be hard­panned left and right. If you wish to have both guitars panned to the center so that they project from both speakers in PA setup, press the MONO button next to the MAIN level control.
If connecting an active acoustic guitar signal to CH 1 or CH 2, engaging the HPF is recommended for rolling-off “boominess”.

GAIN
Gain controls the level of the microphone or line level signal plugged into the mixer. If the gain is set too low, the output signal will be noisy when you turn it up at the level control. If gain is set too high, it will distort.
For best performance, set the gain while looking at the meters. Turn the Level control so that it’s facing straight up. Then turn the gain up until you see the first or second lights on the meters. Don’t set it too high – although you might not hear distortion when playing by itself, when all of the channels are playing at that level they may add together and distort the mixer.

Sidebar: “Why are there two volume controls?
The Gain and Level controls work together to get the best performance out of the mixer. A quiet signal may need more gain than a loud guitar amp going into a sensitive microphone. Set the gain so that the level on each channel is roughly the same, then use the Level controls to set the balance that you want in your mix.

GAIN STAGING
Gain staging involves setting the serial amplification stages of an audio signal in a way that achieves best signal-to-noise ratio. Improper gain staging can result in more background noise, less clarity and lower sound system efficiency. If your mixer is connected to a FOH amplifier or powered speakers, you will need to first set the level of these for an appropriate audience listening level. To set your FOH amplifier or powered speaker level, connect a full-range line level music source to your mixer and set the peak level on the channel meters somewhere between -6dB and 0dB. Set your main output level to zero/unity and slowly bring up the amplifier or powered speaker levels to a volume that makes sense for the venue. With this main output level set, you can move on to setting levels for the individual inputs. Start with gain and channel level controls at their minimum positions. For microphone signals, while speaking or singing into the connected microphone, slowly bring up the channel GAIN control until only the loudest input briefly triggers the channel CLIP indicator LED. Reduce the GAIN control slightly from this level. With the main output level control set to zero/ unity, continue speaking or singing into the connected microphone and slowly bring up the channel LEVEL to a desired listening level. Follow this process for any microphone signals. When setting relative levels between channels, best practice is to reduce levels of signals that are too loud, working subtractively.

EQ HI

FREQUENCY RESPONSE

The high EQ control is a shelving EQ. What this means is that it boosts or cuts from 1 0kHz and everything above that. Turn it up to bring out the breath of a vocal or the high overtones of the cymbals. Turn it down to reduce finger squeaks on a guitar or bass.
The high EQ control is a shelving EQ. What this means is that it boosts or cuts from 12kHz and everything above that. Turn it up to bring out the breath of a vocal or the high overtones of the cymbals.
Turn it down to reduce finger squeaks on a guitar or bass.

EQMID

The mid-EQ is a peaking EQ, centered at 2.5kHz. This boosts or cuts the high midrange of your signal. You might turn it up if your vocal isn’t cutting through the mix, or turn it down if a percussion port is too harsh.

EQ LOW

This low EQ boosts or cuts everything from l00Hz or below. You might bring it up for more bottom out of your kick or boss guitar, and turn it down to reduce rumble from a vocal or wind instrument.

GLOSSARY OF TERMS

• BALANCED
  A 3-conductor (including shield), low-impedance connection. Balanced cables are the preferred method for hum-free interconnection of a sound system for their noise-rejection characteristics.
  (Also see Unbalanced.)

• BUSS
  An output destination in a mixer. For example, the left and right main outputs are called busses, because you can send a channel to one or both of them. Also spelled Bus

• CHANNEL
  One of any number of signal paths in an audio circuit, such as input channel, output channel, recording channel, left channel, right channel, etc.

• DECIBEL (DB)
  A term representing the ratio between different audio levels. It can either refer to the electrical signal running through a channel or the acoustic sound level coming from a sound source.

• EQUALIZATION
  Electronic filters that adjust the level of certain frequencies. Used for tone enhancement or to reduce extraneous sounds. Two types of EQ shapes are Peak and Shelving, described below.

• HI-Z (HIGH IMPEDANCE)
  In the audio equipment realm, the term “Hi-Z” or “High-Impedance” generally refers to inputs designed for passive guitar or bass signals ( 1 MQ or thereabouts).

• HPF (HIGH-PASS FILTER)
  An electronic filter that passes signals with a frequency higher than a specific cutoff frequency and attenuates signals with frequencies lower than the cutoff frequency.

• IMPEDANCE
  Resistance in an electrical circuit measured in Ohms (Q). Maintaining proper impedance (between amplifier and speakers for example) is important to prevent damage to the amp.

• 48V PHANTOM POWER
  A voltage signal that runs through a microphone cable to power condenser microphones. Harmless to microphones that don’t need it, except for very old and/or damaged ribbon microphones.

• SHELVING EQUALIZER CONTROL
  Increase or decrease of all frequencies above or below a specific point.
  (Compare to Peak Equalizer Control; see pages 8-9 for more information.)

• TRS
  Acronym for Tip-Ring-Sleeve – the three parts of a three-conductor (including shield) audio plug. TRS phone plugs are often used for “balanced” mono connections, or stereo “unbalanced” (head-phone) connections.

• TS
  Acronym for Tip-Sleeve, the two parts of an unbalanced, two-conductor
  (including shield) phone plug. TS connectors are some-times called mono or unbalanced plugs or jacks.

• UNBALANCED
  A two-conductor (including shield), high-impedance connection. These are most commonly used for instrument connections and cable runs of less than 20feet.

• XLR
  The three-pin connector universally used for balanced audio connections. A balanced connection reduces outside noise and interference.
  (See Balanced above.)
