PS Amplifier Operation

Dialing in your Sound


1. Before turning your amplifier on always set the MASTER volume control to the
zero position. This will prevent damage to your speakers in the event of a product
failure or faulty input signal.
2. Turn the amplifier on using the power switch located on the right side of the
amplifier’s front panel. The POWER indicator light on the front panel will illuminate in
green. Upon power-up, the MUTE feature will engage and its light will be illuminated
red. You will also see the PEAK light illuminate green.
3. Turn the volume controls on your instrument to their full, or loudest positions.
4. Set the PS amplifier EQ controls (bass, mid, and treble) to zero (twelve o’clock
position) and begin playing aggressively while turning up the Gain control. When the
LED light is green there is still potential to increase the Gain. When the light turns
red, your input is too hot and your signal will distort. For the cleanest sound, allow
the LED indicator to turn red intermittently while playing at the most aggressively.
5. Disengage the MUTE button. It’s light will turn off.
6. Turn the MASTER Volume Control clockwise to the desired listening volume. At
this point you should be hearing your instrument through the connected speakers.
7. By adjusting the EQ controls and utilizing the mid-cut features, the sound of your
instrument can be shaped in very subtle or very dynamic ways. Epifani pre-amps are
designed to act like the channel strip of a professional mixing console – a little EQ
goes a long way. In fact, many sound engineers start with the EQ in the flat position
and CUT frequencies to achieve the desired sound. They then add gain to make up
the loss of volume due to the reduction in EQ. Cutting back is typically preferred to
boosting. If you are dramatically boosting all of your EQ settings, you might want to
call your Epifani Dealer or us directly to discuss your setup.
8. The MID CUT level adjusts the amount of mid-range frequencies that will be
reduced when you engage the MID CUT switch either by pressing the switch on the
front panel or activating the switch via the footswitch. This feature actually gives you
an additional level of control as you change playing styles or when changing your
instrument. It’s almost like having a second channel.

Please consider that different acoustical environments can effect your sound
dramatically. Different positions on stage or whether your speakers are higher or
lower can change the sound you and the audience hear. You have the option to
change your position or use the EQ controls to accommodate different sounding
spaces. The Epifani EQ section is a powerful tool and with a bit of experimenting
you’ll find that almost any sound can be achieved.
