Audio Tips

#1 - Setting the Gain (SENS)
This is probably one of the most important control knobs on any mixer. It is designed to maximize the input level of any audio signal. This is important because if the Gain (SENS) is set too low, the audio system will produce a hiss. Conversely, if the Gain (SENS) is set too high, the audio system will produce distortion. If the following steps are taken, the audio signal will be maximized.
  1. Turn the Gain (SENS) knob fully counterclockwise.
  2. Press the PFL/Solo switch on the channel you are using.
  3. Set the fader to the O position.
  4. Play your audio source (i.e. speak into mic, play CD/Cassette, instrument, etc.)
  5. Turn the Gain (SENS) knob clockwise until the LEDs read between 3-6 (yellow lights).
  6. Depress the PFL/Solo switch.
  7. Repeat this procedure on each of the other channels.
After you have completed the Gain (SENS) adjustment on each channel, the audio signal inputs are maximized. If you notice a channel is too loud, simply pull the fader down to the desired level. By doing this, you will lower the volume of the respective channel without affecting the channel's audio signal that was just maximized.

#2 - Phantom Power
Phantom Power is the +48v DC voltage power that is applied to condenser microphones. In order for any condenser microphone to function properly, the phantom power must be activated on the mixer. If the phantom power is not turned on at the mixer, these microphones will not work. We use condenser microphones in several of our audio installations. These condenser microphones are generally used on pulpits and choirs.

****************************************************** IMPORTANT ******************************************************

It is extremely important to never turn on the phantom power switch while the sound system is on. If you notice that the sound system is already turned on and the phantom power switch is turned off, the best thing to do is the following:
  1. Turn off the sound system.
  2. Turn the phantom power switch on.
  3. Turn the sound system on.
By doing so, you will protect your sound system and all the components currently connected to the sound system.


Guitar Tips

#1 - Strings Binding in the Nut
This is a very common problem that has an easy fix. The cause is usually the current gauge string being too large for the slot in the nut. The best solution is to file the slot out a little larger. This is not a difficult repair, but if you think it is too much for you, bring your guitar into the guys at Pro Sound Music Shop. However, there is a quick fix:
  1. Smooth the nut slot by coloring the slot with a No. 2 pencil.
  2. A drop of candle wax in the slot works well also.
#2 - Seasonal Maintenance
It is a good idea to have your guitar serviced every change of season. Due to the changes in temperature and humidity, the guitar's tone and playability can be affected. The following are some good things to check.
  1. Does the guitar play as well as it used to?
  2. Do all the notes sound clear?
  3. Are you experiencing tuning problems?
  4. Do the electronics sound scratchy?
These are just a few indicators that suggest your guitar may need to be serviced. If you are experiencing any of these problems, bring your guitar into Pro Sound and let the pros help!
