Important: Precautions & Safety Guidelines
All KHAN products are designed for continuous safe operation, as long as common sense is used and steps are taken to help avoid certain
problems. Abiding by the following rules can help prevent damage to your amplier, yourself and others.
• The amplier is equipped with a three-pronged AC power cord. To reduce the risk of electrical shock, never remove or otherwise
attempt to defeat the ground pin of the power cord.
• Connect the amplier ONLY to a properly grounded AC outlet of the proper voltage for your amp.
• Always match the total speaker impedance to the amplier.
• Unplug the amplier before cleaning it. NEVER spray liquid cleaners onto the amplier. Wipe it with a slightly dampened, lint-free cloth
to remove dirt and lm.
• Ampliers capable of producing high volume levels are also capable of inicting permanent hearing loss or damage, if the exposure to
such levels is prolonged. Such damage is progressive and irreversible!

Single Channel (PAK) Model

Single Channel (PAK) Model
Input: High 1 Megohm input impedance for maximum signal and tone from your
instrument. Standard ¼” jack
Gain: Controls the gain of the preamp. Adjust to taste for the sound desired. The
gain structure of the Pak Amp is very dynamically responsive. Even at maximum gain
the amp will clean up well with the guitar volume knob.
Bright Switch: Adds brightness and boosts the preamp gain above 1KHz. This is a
useful switch to compensate for different types of pickups.
Treble: Controls the high frequency response of the amplier at a frequency of 2
KHz. Adjust to taste with your particular guitar and pickups
Mid: controls the midrange response at 900 Hz. This control “lls” the sound or
“scoops” it for more clarity and sizzle
Bass: Controls the low frequency response at 100 Hz. Adjust this to taste with the
speaker cabinet of choice.
Mid Boost: Adds a thickening boost that drives the power amp with full range
signal. This is foot switchable via ftsw jack on both models.
Footswitch Jack: Use any one button footswitch. The footswitch will activate the
mid boost function.
Master: Controls the overall volume of the amplier. Full output is achieved around
¾ of the way up. Increasing the master beyond this adds power tube breakup and
compression.
TIP #1: Although any cabinet may be used, the Pak Amp is best suited with a
“greenback” type speaker cabinet. Some modern speakers tend to be peaky
and harsh in the midrange. Speakers are critical to the tone as they are the nal
component to transfer the electrical energy into sound.
