UL 901

Bass Amp

Thank you for purchasing a UL 901 Bass Amp, and welcome to the Epifani family! You are about to experience

Legendary Sound. We hope you love it.

Being an Epifani player puts you in the company of some of history’s most inuenal bassists. Aer all, it

was their invaluable feedback that helped Nick Epifani design every amp, combo, and cabinet down to the

smallest detail. Over the past 23 years, we’ve been making bass gear in cooperaon with legends like Anthony

Jackson, Oteil Burbridge, and Ron Carter, just to name a few. Our relaonship with them has shaped the Epifani

experience you’ll have today and in the future.

Your UL 901 is as much a piece of hand-craed, Hi-Fi studio gear as it is a rugged, road-ready bass amp.

Every detail has been meculously engineered to ensure you’re able to dial in exactly the sound you want in any

playing situaon.

Less is more

When dialing in your perfect tone, keep in mind just how powerful the UL 901’s controls are. Nick recommends

making small EQ shis at rst. When it’s set at, the amp will produce a precise aural picture of your bass,

strings, and hands. You might nd that just a small adjustment brings your perfect tone into focus in most

playing situaons.

We also recommend that you experiment with cung the bass, mid, and treble just as much boosng them.

Somemes the shortest distance between you and your perfect tone is taking out a lile of the boom caused by

a hollow stage, or the bark of a bass with too much gain from the bridge pickup.

We want you to have an incredible Epifani experience. So, if there is anything at all we can do to help,

please feel free to get in touch any me. You can reach us online at www.Epifani.com/support or over the phone

at (888) 925-3781.

Thank you. And, have fun!

grounding-type plug. A polarized plug has two blades

with one wider than the other. A grounding-type plug has

two blades and a third grounding prong. The wide blade

or third prong is provided for your safety. If the provided

plug does not t into your outlet, consult an electrician for

replacement of the obsolete outlet.

10. Protect the power cable from being walked on or

pinched parcularly at the plugs, convenience receptacles,

and the point where they exit from the apparatus.

11. Only use aachments/accessories specied by the

manufacturer.

12. Use only with the cart, stand, tripod, bracket, or table

specied by the manufacturer, or sold with the apparatus.

When a cart is used, use cauon when moving the cart/

apparatus combinaon to avoid injury from p-over.

13. Unplug this apparatus during lightning storms or when

unused

for long periods of me.

14. Refer all servicing to a qualied service personnel.

Servicing is required when the apparatus has been damaged

in any way, such as the power-supply cord or plug is

damaged, liquid has been spilled or objects have fallen into

the apparatus, the apparatus has been exposed to rain or

moisture, does not operate normally, or has been dropped.

15. Do not overload wall outlets and extension cords as this

can result in a risk of re or electric shock.

16. Never push any foreign objects of any kind into the

openings as they may touch dangerous voltage pointsthat

could result in re or electric shock. The apparatus shall not

be exposed to dripping or splashing and no objects lled

with liquids such as a beverage container should come in

contact with the unit.

17. This apparatus has been designed with Class-I

construcon and must be connected to mains socket outlet

with a protecve earthing connecon (the third grounding

prong).

18. The MAINS plug or an appliance couple is used as the

disconnect device, so the disconnect device shall remain

readily operable.

19. Exposure to extremely high noise levels may cause

permanent hearing loss. Individuals vary considerably in

suscepbility to noise-induced hearing loss, but nearly

everyone will lose some hearing if exposed to suciently

intense noise for a period of me.

1. Input Jack

Connect your instrument using a standard 1/4 inch

instrument cable.

2. Acve/Passive Switch

Provides a 10 dB cut for acve basses to avoid

unwanted distoron.

3. Gain

Controls the volume of the signal passing through the

EQ stage.

4.Bass

Acve shelving EQ with 22 dB boost @ 40 Hz

5. Mid

Acve bandpass EQ with 17 dB boost @ 450 Hz

6. Treble

Acve shelving EQ with 22 dB boost @ 3 kHz or 6 kHz

7. Treble Shi

Sets the apex for the Treble control to 3 kHz if pushed

in, or 6 kHz if out.

8. Mid Cut Switch

Acvates Mid Cut EQ. Green light is on when acve.

9. Mid Cut Level

Provides up to 8 dB of cut @ 800 Hz. When engaged,

turning the knob all the way to the right (clockwise)

produces no cut. Turning the knob to the le

(counterclockwise) cuts high-mid frequencies.

10. Mute

Mutes the amplier. Red light is on when engaged.

11. Master Volume

Controls the overall volume of the amplier. Other

outputs including the DI, Tuner Out, and

Eects Send are not aected by the Master Volume

control.

Note: The Mute is automacally engaged when you

turn on the amplier so you can set your Gain level

before sending sound through to the speakers.

Front Panel Rear Panel

1, 2. Eects Loop Send and Return

Use a 1/4-inch cable to connect the input of your

eects to the Send jack, and the output of your

eects to the Return jack.

3. Eects Mix

Mix between a dry (unaected) signal and a wet

(eected) signal when using the Eects Loop.

4. Pre/Post EQ Switch

When the switch is engaged (post EQ) DI signal will be

shaped by the acve EQ. When the switch is

disengaged (pre EQ), EQ will not aect DI.

5. DI Level

Front Panel Rear Panel

Get Ready

1. Before turning your amplier on, always set the

MASTER VOLUME control to the zero posion.

2. Turn your UL 901 on using the power switch located

on the back of the amplier. The POWER indicator

light on the front panel will illuminate.

Note: Upon power-up, the amplier will go through

a self-diagnosc test for about 2 seconds before it is

fully funconal.

Then, the MUTE feature will engage and its light will

be illuminated red. You will also see the PEAK light

illuminate green.

4. Turn the volume controls on your instrument to their

full, or loudest posions.

5. Set the EQ controls (BASS, MID, and TREBLE) to

zero (twelve oʼclock posion).

Set The Gain

6. With the MASTER VOLUME sll set at zero, begin

playing aggressively while turning up the GAIN control.

When the LED light is green there is sll potenal to

increase the gain. When the light starts ashing red,

your input is too hot and your signal will distort.

For the cleanest sound, allow the LED indicator to

ash red intermiently while playing aggressively.

Make Some Noise

7. Disengage the MUTE buon. Itʼs light will turn o.

8. Turn the MASTER VOLUME control clockwise to

the desired listening volume. At this point you should

hear your instrument through the speakers.

Sculpt Your Sound

9. By adjusng the EQ controls, the sound of your

instrument can be shaped in very subtle or very

dynamic ways.

The UL 901 pre-amp is designed to work like the

channel strip of a professional mixing console—a lile

EQ goes a long way.

In fact, many sound engineers start with the EQ in the

at posion and cut rather than boost frequencies to

achieve the desired sound.

They then add gain to make up the loss of volume due

to the reducon in EQ. Cung back is oen preferred

to boosng.

10. The MID CUT level adjusts the amount of mid-

range frequencies that will be reduced when you

engage the MID CUT switch.

This feature actually gives you an addional level of

control as you change playing styles or when changing

your instrument. Itʼs almost like having a second

channel.
