Paul W. Klipsch

Legendary knowledge.

In 1978, Paul W. Klipsch was awarded the Audio Engineering Society's second highest honor, the prestigious Silver Medal, for his contributions to speaker design and distortion measurement. Mr. Klipsch was inducted into the Audio Hall of Fame in 1983. In 1997, he was inducted into the Engineering and Science Hall of Fame, an honor shared by Thomas Edison, George Washington Carver and the Wright brothers.

While perhaps we all can't be so brilliant, we can certainly do our part to pass along nuggets of his genius, as well as basic audio info for the layperson. Which is why we have this section of our website. Use the search form below to enter some keywords based on what your are looking for.

Happy learning!

  • Will the KMC 3 recharge my rechargeable batteries?

    No, the KMC 3 will operate on alkaline or rechargeable “D” cell batteries but is not designed to act as a charger for rechargeable batteries.  If you decide to use rechargeable batteries, make sure you also have a separate charger to recharge them.

  • What is the best way to clean the KMC 3?

    The KMC 3’s cabinet is coated with a soft-feel type of paint.  Dry dusting or cleaning with a dry or water-damp cloth is the best cleaning method for the cabinet and rubber top “shelf’. If any particles are lodged in the top shelf, adhesive tape will clean it up. The front grille should only be dusted with a dry cloth.

  • Can I use the KMC 3’s USB input to charge my phone or portable music device while the KMC 3 is on battery power?

    Yes, but NOTE that charging any device through the KMC 3’s USB input while the KMC 3 is running on battery power will significantly shorten battery life. We recommend only charging your device for a short time period and only when absolutely needed when the KMC 3 is on battery power.

  • Does the KMC 3 remember the last Bluetooth device it was paired with?

    Yes, when you activate the Bluetooth pairing feature on the KMC 3 it will search for the last Bluetooth device it was paired with, automatically connect with it, and play it through the Bluetooth “input”.  If that device is not available or does not have Bluetooth engaged, the KMC 3 will automatically switch to the AUX (3.5mm) input as its source.

  • What type of batteries work best and last the longest in the KMC 3?

    We recommend alkaline “D” cell batteries or, especially if battery power will be used often, rechargeable “D” cell batteries with a separate charger (the KMC 3 will not recharge batteries).  For many of our tests we used Energizer alkaline “D” cells, rated at between 10,000-20,000 mAh, depending on the load. With batteries, like anything else, you get what you pay for so we recommend a known brand name with a higher mAh rating.  NiMH rechargeable batteries and a charger for them cost more initially but would pay for themselves in the long run if you plan to use battery power on the KMC 3 frequently.

  • Bass periodically cuts off for short times when playing the KMC-3 at high volumes.

    This is a sign that your battery power is becoming weak because the system is demanding more power than the weakened batteries can provide.  Play at a lower volume until you replace (or recharge with a separate charger if using rechargeable) the batteries, or switch to AC power.

  • How long before the KMC 3 goes into Standby mode if no music is played through it?

    When it is on AC power the KMC 3 goes into Standby after 1 hour of non-use and, when on battery power, after 5 minutes of non-use.

  • What types of devices have Bluetooth music streaming capability so they work with the KMC 3?

    Bluetooth devices capable of wireless music streaming are identified as having the Bluetooth Advanced Audio Distribution Profile (A2DP). Examples (partial list only) of devices that automatically have Bluetooth A2DP are:

    Apple devices: 

    iPhone 3G, 3GS, 4, 4S, 5

    iPad tablets (All generations)     

    iPod touch 2nd, 3rd and 4th generations

    Nokia phones:

    Lumina 620,820,920,928,1020

    Samsung devices:

    Galaxy S III, Galaxy S4 phonesGalaxy 10.1 tablet

    LG phones:

    Optimus G, Optimus F7

    HTC phones:

    HTC One, Evo, Droid DNA

    Blackberry phones:

    Blackberry Q10, Z10

    Motorola phones:

    Droid Razr

    Other tablets:

    Lenovo Thinkpad, HTC Jetstream, HP Touchpad, Microsoft Surface, Dell Streak

  • Will the USB input on the back of the KMC 3 both play and charge my portable music device?

    The KMC 3’s USB input will only charge most portable music devices using the cord that came with the particular device. Music devices without a Bluetooth feature can be played on the KMC 3 by connecting a 3.5mm to 3.5mm cord between the device’s headphone output and the KMC 3’s 3.5mm input on the rear, then changing the KMC 3 to its 3.5mm input. USB charging occurs when the KMC 3 is on either AC or battery power but NOTE that charging a device while the KMC 3 is running on battery power will significantly shorten battery life. We recommend only charging your device for a short time period and only when absolutely needed when the KMC 3 is on battery power.

  • For charging purposes, what is the Voltage and Amperage output of the KMC 3’s USB output?

    5 Volts DC/1 Amp
