PORTABLE SOUND SYSTEMS

Fender Musical Instruments 7975 North Hayden Road, Scottsdale, Arizona 85258 U.S.A.

Fender knows the importance of sound reinforcement. From the simple box-top mixer to today's professional touring concert systems, the need to communicate, to make the connection between the performer and the audience is foremost in Fender's mind.

Perhaps no other single piece of gear can make or break your band's sound.You see, your sound system is more than just a combination of dials, wires and speakers. It is an integral part of the audio chain and should be treated with special care and attention to detail.

At Fender, we know what building quality musical instruments and sound reinforcement equipment is all about. In fact, many of the world's best sounding electric musical instruments and sound reinforcement equipment proudly wear the Fender name.

Whether you need a simple box top powered mixer for your Saturday afternoon jam, or a professional full-size concert system, Fender has the sound reinforcement equipment to meet your needs. Likewise, your decision to purchase Fender pro audio gear is one you will appreciate with each performance for years to come.

Wishing you years of enjoyment and a heartfelt thank you,

INTRODUCTION

THE FENDER LTB PORTABLE POWERED

MIXER

4

A. EQ - Adjusts the tone / frequency boost or cut of its respective channel. When the tone control is set at the 12 oclock (notched) position, the channel is flat with no frequencies cut or boosted. As the dial is rotated clockwise, the treble response increases. Likewise, as the dial is rotated counterclockwise the treble response decreases.

B. EFX - This knob controls the amount of signal its respective channel sends to the EFX output jack for external signal processing devices and to the internal reverb pan. When the knob is set at 0, no signal is sent to the EFX output jack for external signal processing or to the internal reverb pan.

C. LEVEL - Adjusts the volume of the individual channel. Rotating the knob clockwise increases the respective channels contribution to the Main Out mix. After slowly raising the MAIN volume control, slowly bring up this input level control listening for the onset of feedback or howling or until the desired level is reached. The LTBs overall volume can be increased by rotating the MAIN control clockwise.

D. HIGH Z - Plug your high impedance microphones, keyboards, drum machines, outboard effects, etc. in here. This 1/4 inch, TS unbalanced input jack is suited for use with items having line level outputs.

E. LOW Z - Plug your microphone in here. This three pin XLR balanced female input connector is intended for input signals from low impedance microphones. Pins 2 and 3 automatically provide Phantom Power (+15V DC) for some condenser style microphones.

D E

A. LOW - Adjusts the amount of low frequency boost or cut in the LTB. When all the tone controls are set at their 12 oclock (notched) position, the LTB is flat with no frequencies cut or boosted.

B. MID - Adjusts the amount of middle frequency boost or cut in the overall mix.

C. HIGH - Adjusts the amount of high frequency boost or cut in the overall mix.

D. MAIN - The main volume control of the LTB. Rotating the knob clockwise increases the LTBs overall volume level.

E. REV - Adjusts the reverb signal level sent to the main mix. Rotating the knob clockwise increases the amount of reverb signal.

F. POWER LED - This LED illuminates when the LTB is on.

G. POWER SWITCH - Turns the AC power ON and OFF.

H. MAIN - This 1/4 inch, TS, unbalanced, line level output is designed to feed the LTBs main bus signal to an external power amplifier or main house mixer.

I. EFX - This 1/4 inch, TS, unbalanced, line level output jack is designed to feed the LTBs effects bus signal to an external signal processing device, such as a digital delay or a chorus unit.

J. AUX IN - This 1/4 inch, unbalanced, TS, line level input jack is designed to accept signal from an external processing device, such as a digital delay or a chorus unit. Any signal entering this jack is mixed into the Main bus signal.

K. FTSW - This 1/4 inch, TS, unbalanced, output jack is designed for use with an optional footswitch (P/N 048458). When a footswitch is inserted into this jack, the LTBs internal reverb can be turned on or off remotely.

5

L. POWER SUPPLY CORD - This is a grounding type supply cord to reduce the possibility of shock hazard. Completely unwind the cord from its cord wrap to prevent blocking air flow. Be sure to connect the cord to a grounded receptacle. DO NOT ALTER THE AC PLUG.

M. PARALLEL SPKR JACKS - These speaker level output jacks feed your main speaker enclosures. Remember, the total minimum impedance load is 4 ohms. Connecting a load of less than 4 ohms may result in unsatisfactory performance such as overheating to the point of thermal shutdown.

Next, slowly bring up the appropriate channel input level control (ie: if the microphone is plugged into the channel 1 inputs, the appropriate channel control is labeled 1), listening for the onset of feedback or howling or until the desired level is reached. The LTBs overall volume can be increased by rotating the MAIN control clockwise.

9. If using external signal processing devices, slowly raise the appropriate channel EFX control until the desired level is reached (ie: if the microphone is plugged into the channel 1 inputs, the appropriate channel control is labeled 1).

BASIC SETUP OF YOUR LTB

7

Ground loops are one of the most common causes of hum and buzz in sound reinforcement systems and other audio products. A ground loop usually occurs i f the separate pieces of equipment are plugged into different AC

circuits. Also, if the audio wiring is placed too close to the power cords, hums or buzzes can bleed into the system. Still, improperly maintained power and audio cables are yet another cause of bothersome noise. In order to help minimize stray hums and buzzes, here are some helpful hints.

1. Keep all electronics connected to the sound system on the same electrical circuit.

2. Keep audio signal cables away from the AC power cords.

3. Use balanced cables when applicable.

4. Always plug the LTB into a grounded AC electrical outlet.

5. Be sure to use properly maintained cords and cables with the LTB.

The LTB mixer and speaker cabinets are covered in vinyl for long life and lasting good looks. To clean the cabinets, use a sponge dampened with a light soapy solution. Avoid spilling any

liquids on the operating surface, grilles, volume and tone controls, switches and l ine cord inputs. ALWAYS unplug the LTB before cleaning it or approaching it with fluids. Before plugging in the LTB wait until the unit has completely dried.

If the LTB is set up but does not function, please check the following items:

Is the LTB 's power cord properly plugged into an electrical outlet?

Is there power at the outlet? Are the volume control knobs on the LTB turned

above the MIN position? Are the volume control knobs on your instruments

turned above their minimum position? Is the mic/instrument properly plugged into the

LTB ? Is the mic/instrument turned on? Are your audio cables frayed, cut or damaged? If using an outboard gear, are the cords

properly connected? Are the speaker cables properly connected? Is there power to the outboard gear? Are the levels on your outboard gear above their

minimum positions? (If applicable) does your instrument have power?

If after checking all of the above the LTB is still not performing correctly, consult your nearest authorized Fender Service Center.

RUNNING AN EFFECTS PROCESSOR THRU YOUR LTB

1. Connect speakers, microphones and other equipment to the LTB as before.

2. Next, connect a cord from the EFX jack to the input on the effects processing unit. Return the signal to the LTB by connecting a cord from the output of the effects unit to the AUX IN jack on the LTB.

3. The EFX knob on each channel adjusts the amount of signal sent to the EFX jack where the signal is then sent to the processor.

4. Be sure to turn on the tape deck, keyboard or other instruments and outboard gear before powering up the LTB.
