XL extra lead

TUBE POWER HEAD Congratulations! You have chosen the highest quality product now available in the market. The new XL head is characterized by the best tube amplification matched with high quality manufacturing and beautiful design. It is carefully hand-made assembled following the best Italian handcraft tradition. Every component has been carefully tested for a professional use. Before playing, we advise you to get familiar with your XL and carefully read the advice and explanations hereby reported. In this way you will be able to know your XL better finding out its characteristics and appreciating its high quality and versatility. When you first switch your XL on, we advise you to play without any effect connected so that you get to know the sound characteristics of the different controls. Do not connect preamplified effects (footswitches, multieffect preamps, boost/overdrive footswitches , preamps, etc.) to the send/return XL loop in order to avoid unpleasant sound changes. Read and carefully follow all the instructions in order to avoid damages to things or people. All our units are hand made. For this reason you could find little design or sound differences. All this as guarantee that you bought a true hand made product.

USER’S MANUAL AND CHARACTERISTICS

CHANNELS: CLEAN/BOOST/XL

CONTROLS FUNCTION ADVISED VALUE CLEAN: •GAIN amplification 5/6 BRIGHT more brilliant and less harmonic sound as you prefer •BASS 100Hz Bass as you prefer •MID 500Hz Mid as you prefer •HI 2KHz High as you prefer •MASTER preamplified signal 6/8 BOOST: •GAIN amplification 7 NORMAL normal sound as you prefer FAT fatter sound as you prefer EXTRA more agressive and fatter sound as you prefer •BASS 120Hz Bass as you prefer •MID 600Hz Mid as you prefer ADD adds presence as you prefer 0 normal as you prefer CUT eliminates presence as you prefer •HI 3KHz High as you prefer •MASTER preamplified signal 5/7 XL: •GAIN amplification 4/8 •BASS/MID/HI same controls of BOOST as you prefer •MASTER preamplified signal 5/7 P.S.: The MASTER knobs control the preout level which is placed on the rear panel.

OTHER CONTROLS VOLUME: sound volume of the power amplification PRESENCE: it controls the power amplifier brightness MAIN: general switch on (red light on) STD-BY: it supplies high voltage to the circuit SPEAKER IMPEDANCE: it selects the speakers impedance (Remember: with two 16Ohm speakers you have to select 8Ohm; with two 8Ohm speakers you have to select 4Ohm) SPEAKER OUT: two outputs in parallel for the speaker/s. REMOTE*: it controls the channel switch through an external switcher. FOOT SW: supplied footswitch for the channel switch

TUBE MIXER CIRCUIT SIGNAL LVL: it controls the not processed signal which goes to the power amplifier. P.S.: if this knob is placed on «0» position, the amplifier doesn’t receive the preamp sound. EFFECT LVL: it controls the processed signal. (AMP LVL): this input can also be used as a power amp input using an external preamp (AMP LVL). SEND: signal to be processed. RETURN: signal input from the effect. PRE OUT: line preamplified signal output for an external amplifier. * When passing from using the external switcher to the footswitch and viceversa, switch the head off first.

PREAMP TUBES

The preamp tubes are used to preamplifier the signal. They usually last the entire life of the amplifier.

The possible problems of these kind of tubes are: microphonics and noise.

MicrophonicsThe microphonics is the ability of a tube to reproduce external vibrations further the signal.This phenomenon can be much more evident in high gain stage like the distortion channels.

Lightly tapping on the glass side of the preamp tubes, while the head is on, you' ll hear a stroke through thespeaker, this is normal don' t worry.But if you hear hi frequencies (ringing or squealing) and in some case a distorted sound, it means that the tube ismicrophonics.

You will note that the first tube is more subject to reproduce this stroke more than the others, because it' s atthe begin of the preamplification chain.

NoiseTube has an own intrinsic floor noise that comes from its work and construction.

During tube life this noise may increase creating a sort of a ringing or squealing.In these two cases, you have to find the defective tube and repleace it with a new one.

The preamp tube doesn't need to be selected, (normally this control has been made by the constructor), but be sureto replace with good quality tubes.We suggest thay you use tubes of same brand and model.

POWER TUBES

Power tubes are the last amplification stage before the out trasformer and speaker out, and they can get exhausted.

Normally a power tube working in A/B class lasts 800 - 1000 hours. It depends also on the volume used.

In an amplifier with same power, in A class, the tube lasts 600 - 800 hours. In this class work tubes are more stressed.

When replace power tubes

You can recognize an exhausted tube because there's a loss of power and volume. Sound has not the same impact,in particular on low frequencies.

Main faults on this kind of tube are :- short inside the tube. In this case normally the HT fuse will blow.- tube light off. It's easy to recognize this problem tube because you can't see any light inside the tube.- tube become glowing. In this case there's an increase of noise (hum) and sound will be distorted.

In all the above cases tubes can' t be fixed, and have to be replaced.

If the problem tube has worked more that 1 year, we suggest that you replace all power tubes, this to guarantee thebest performance of your amp.

If the problem tube has less than 1 year you can replace only that one.

Warning!!You have to mount only selected and matched tubes, with the same characteristics of the tube supplied on youraplifier. See the ''Matching Reference'' label on the tube.If you mount tubes with different ''Matching Reference'' is necessary to adjust the Bias, to let the amp work properly.

GENERAL INFORMATION

MODULATION EFFECTSThe main characteristic of the modulation effect (see example) is to add and/or lay other wave forms to the signal.This kind of effect should be used in the loop effect of your amp, that is between the Premaplifier and the Poweramp.

SYNTHESIS EFFECTSThe main characteristic of the synsthesis effect (see example) is to modify the signal wave form. (i.e. thedistortion effects).This kind of effect should be used between the guitar and the input of your amp, in a standard connection chain.

SERIAL LOOPIn a Serial Loop all the output signal coming from the Preamp passes throught the effect. In this case on youreffect unit it is necessary to adjust the balance between the DIRECT (DRY) and the EFFECT( WET).

PARALLEL LOOPIn a Parallel Loop only a part of the direct sound passes throught the loop effect, without going out from theSend. This part of the signal will be mixed with the signal that comes from the Return.In this connection the quality of the effect is not so important as it is in the Serial Loop connection, because theDirect will be kept by the loop (see drawing).
