Introduction

ENGLISH

Congratulations on purchasing the Hartke Model 3500/5500 Bass Amplifier! Although this unit is designed for easy operation, we suggest you first take some time to go through these pages so you can fully understand how we’ve implemented a number of unique features.

The Model 5500 provides 500 watts of power to a 4 ohm speaker system or 350 watts to an 8 ohm speaker system. The model 3500 produces 350 watts to a 4 ohm speaker or 240 watts to a 8 ohm speaker. With that kind of power, the Model 3500/5500 is EXTREMELY loud and punchy. In addition, the Model 3500/5500 offers a number of additional advanced features, including frontpanel compression and graphic equalizer LED indicators, effects send and return jacks, an effects send/return balance knob, a direct output with ground lift and pre or post EQ selection.

The Model 3500/5500 is optimized for use with electric bass instruments, and the front panel controls in both models are virtually identical. You’ll find either to be an excellent bass amplifier for live performance use in small and medium-size venues; in addition, the Model 3500/5500’s advanced pre-amp features makes it ideal for use in recording environments.

In these pages, you’ll find a detailed description of the many features of the Model 3500/5500 bass amplifier, as well as a guided tour through their front and rear panels, step-by-step instructions for setting up and using each product, detailed discussions about equalization and compression, and full specifications. You’ll also find a warranty card enclosed—please don’t forget to fill it out and mail it so that you can receive online technical support and so we can send you updated information about these and other Hartke and Samson products in the future.

SPECIAL NOTE: Should your unit ever require servicing, a Return Authorization number (RA) is necessary. Without this number, the unit will not be accepted. Please call Samson Technologies at (516) 932-1062 for a Return Authorization number prior to shipping your unit. Please retain the original packing material and, if possible, return the unit in its original carton and packing materials.

Features

The Hartke Model 3500/5500 bass amplifier offers all the newest concepts in bass amplification. Here are some of its main features:

• Power to spare — The Model 5500, a full 500 watts delivered to a 4 ohm speaker system or 350 watts to an 8 ohm speaker system. The model 3500 delivers 350 watts to a 4 ohm speaker or 240 watts to a 8 ohm speaker.

• Our unique Transient Attack® circuitry ensures that every nuance of your bass performance is reproduced faithfully.

• Two Pre-Amp input knobs, allowing custom blending of tube and solid state sounds.

• Ten bands of high-quality graphic equalization, allowing you to create a broad range of tonal colors for your bass instrument. A dedicated in/out button allows you to preset an equalization curve.

• Two fully adjustable contour knobs (high pass and low pass), which provide further control over shaping your bass sound.

• A built-in compressor which not only adds real “punch” to your bass sound, but also allows you to smooth out volume differences between notes.

• Two independent inputs that accommodate both passive and active bass guitars.

ENGLISH

• Protection relay circuitry that protects connected speakers from dangerous overloading and also prevents “thumps” when powering on or off.

• Effect loop send and return jacks that allow you to connect to professional outboard effects processors.

• An effect Balance knob which enables you to adjust the relative amount of Send (“dry”) versus Return (“wet”) effect signal being routed to the speaker outputs.

• Electronically balanced direct output that provides a means of routing signal to professional mixing consoles in both live performance and recording environments. A ground lift switch helps prevent hum or buzz from entering the signal, and a pre/post switch allows the direct signal to be derived either before or after the amp EQ section.

• LEDs that show you the settings of the graphic equalizer in low-light envi ronments as well as a two-color LED that continuously shows the status of the compression circuitry in response to your playing.

• Rugged construction makes the Model 3500/5500 eminently road-worthy.

ENGLISH

1. Passive Input jack - If your bass guitar has passive circuitry, connect it to the

Model 3500/5500 here. This standard, 1/4” unbalanced jack provides a high impedance (100 k Ohms) input sensitivity of 20 millivolts.

2. Active Input jack - If your bass guitar has active circuitry,* connect it to the

Model 3500/5500 here. This standard, 1/4” unbalanced jack provides a high impedance (100 k Ohms) input sensitivity of 60 millivolts.

3. Pre-Amp A (Tube) control - This determines the amount of preamplification

being provided by special circuitry which delivers the sound of a classic tube amplifier (this circuitry actually includes a real tube!). Note that when both PreAmp knobs are used at equal settings, the amplifier will be twice as loud as when only one is used. Avoid setting both Pre-Amp knobs on maximum (“10”), since the result will almost always be undesirable distortion.

4. Pre-Amp B (Solid State) control - This determines the amount of preamplifica-

tion being provided by special circuitry which delivers the sound of a solid state amplifier. Note that when both Pre-Amp knobs are used at equal settings, the amplifier will be twice as loud as when only one is used. Avoid setting both PreAmp knobs on maximum (“10”), since the result will almost always be undesirable distortion.

5. Compression LED - Provides a visual indicator of the status of the compression

circuitry. When lit steadily green (for example, when the Compression knob [see #6 on the next page] is set to “Off”), no compression is being applied. When unlit, compression is being applied to the incoming signal at a ratio of approximately 2:1. When flashing red, the compression ratio is approaching infinity (limiting is being applied to peak signals). When lit steadily red, the entire signal is being limited. This LED “follows” the incoming signal, changing continuously as different amounts of compression and/or limiting are being applied. For more information, see the “About Compression” section on page 12 of this manual.

* Bass guitars that have active circuitry normally require a battery for the circuitry to be functional.

Guided Tour - Model 3500/5500 Front Panel

6. Compression control - This determines the amount of compression (peak signal reduction) by simultaneously adjusting both threshold and compression ratio (which ranges from 2:1 to infinity [limiting]). At the fully counterclockwise “Off” position, the circuitry is bypassed and no compression is applied (the knob clicks when set to the “Off” position). As the knob is raised clockwise, (at settings from “1” to “∞”) increasing amounts of compression are applied. For more information, see the “About Compression” section on page 12 of this manual.

7. Graphic Equalizer In/Out switch - When pressed in (the “In” position), the Model 3500/5500’s graphic equalizer circuitry (as described in #8 below) is operational. When pressed out (the “Out” position), it is bypassed. The provision of this switch allows you to set up a custom equalization curve (an equalization “preset”) with the graphic EQ sliders, which can then be activated with the press of a single button.

8. Graphic Equalizer - These sliders allow you to “draw” the tonal response of the system by adding 15 dB of boost or attenuation to ten different narrow-band frequency areas (30 Hz, 64 Hz, 125 Hz, 250 Hz, 500 Hz, 1 kHz, 2 kHz, 3 kHz, 5 kHz, and 8 kHz), affecting the main output signal of the Model 3500/5500. When a slider is at its center detented (“0”) position, the selected frequency area is unaffected (it is said to be flat). When a slider is moved up (above the “0” position, towards the “+15” position), the selected frequency area is boosted, and when it is moved down (below the “0” position, towards the “-15” position), the selected frequency area is attenuated. For more information, see the “About Equalization” section on pages 10 - 11 of this manual.

ENGLISH

9. Contour Low Pass control - This acts as a broad-band low frequency equalizer, providing 18 dB of boost or attenuation at 100 Hz. You should generally adjust this control (and the Contour High Pass control, described in #10 below) prior to “fine-tuning” the system with the graphic equalizer (as described in #8 above). For more information, see the “About Equalization” section on pages 10 - 11 of this manual.

10. Contour High Pass control - This acts as a broad-band high frequency equalizer, providing 18 dB of boost or attenuation at 10 kHz. You should generally adjust this control (and the Contour Low Pass control, described in #9 above) prior to “fine-tuning” the system with the graphic equalizer (as described in #8 above). For more information, see the “About Equalization” section on pages 10 - 11 of this manual.

11. Master Volume control - This is the overall volume control. For best signal-to-noise ratio, keep the output of your bass at or near maximum and adjust the amp’s Master Volume to the desired level.

12. Power LED - Lights whenever the Model 3500/5500 is powered on.

13. Power switch - Use this to power the Model 3500/5500 on or off.

1. Fuse sled - This contains a fuse holder and shows the currently selected voltage rating for your Model 3500/5500. Make sure the voltage rating is correctly set before powering up the amplifier! Fuse ratings are 10 amp for 115 vac and 6.2 amp for 230 vac. For information on how to change the voltage rating, see Appendix B on page 14.

2. AC input - Connect the supplied standard 3-pin “IEC” plug here.

3. Speaker outputs - Connect any 4, 8, or 16 ohm bass cabinet(s) to these standard unbalanced 1/4” jacks. WARNING: Because of the high power levels and low frequency content of the signal generated by the Model 3500/5500, use only appropriately rated speaker cabinets (at least 600 watts at 4 ohms) that are specifically designed for bass instruments. We recommend that Hartke amplifiers be used with Hartke bass cabinets, although other brands of speakers can be used.

4. Fan - The fan provides vital cooling to your Model 3500/5500. Make sure that it is kept free of all obstructions and that cool, fresh air is accessible at all times. Also, try to ensure that the Model 3500/5500 is used in a dust-free environment.

Guided Tour - 3500/5500 Rear Panel

5. Effect Send jack - Use this 1/4” unbalanced jack to send low impedance (100 ohm) signal from the Model 3500/5500 to a professional outboard effects processor such as a reverb, echo, chorus, flanger, or harmonizer device.* Output level is approximately 0 dB to +4 dB and is post-EQ and post-compression but unaffected by the setting of the Master Volume control. You can also use the Effect Send jack to route signal to an external mixing console or amplifier with an input sensitivity of +4 dB.

6. Effect Return jack - Use this 1/4” unbalanced jack to return low impedance (600 ohm) signal to the Model 3500/5500 from a professional outboard effects processor.*

7. Balance control - Use this to adjust the relative amount of Effect Send (dry) versus Effect Return (wet) signal being routed to the Model 3500/5500 speaker outputs. At the center-detented “0” position, equal amounts of Send and Return signal are routed. At its fully counterclockwise (“Send”) position, no signal from a connected effects processor(s) is added to the main output. At its fully clockwise (“Return”) position, the only signal you hear is that coming from a connected outboard effects processor(s). If your outboard effects processor has an adjustable wet/dry control, we recommend that you set the Balance knob to its fully clockwise (“Return”) position and use the effects processor’s wet/dry control to adjust the relative mix. Alternatively, you can set the effects processor to output fully “wet” signal and use the Model 3500/5500 Balance knob to adjust the relative mix of dry vs. wet signal

ENGLISH

8. Direct Out Post/Pre switch - When pressed in (the “Pre” position), signal is routed to the Direct Out jack prior to the Model 3500/5500 ten-band graphic equalizer (but after the compression circuitry and Contour controls). When out (the “Post” position), signal is routed to the Direct Out jack after all compression and EQ circuitry (both ten-band graphic and Contour).** Use the “Pre” position when you want the console engineer to have control over equalizing your bass signal; use the “Post” position when you want to use the front panel ten-band graphic equalizer to equalize your bass signal before sending it to the console.

9. Direct Out Normal/Ground Lift switch - When pressed in (the “Gnd. Lift” position), pin 1 is removed from the chassis. This should be used only when a ground loop hum or buzz is heard; otherwise, leave it in the out (“Normal”) position.

10. Direct Out jack - Use this electronically balanced XLR jack to route signal from the Model 3500/5500 to a professional mixing console or as a tap to a main PA system via a mic input on the console. The signal output from this jack is low impedance (100 ohm) with an output level of approximately -30 to -20 dB. You can also use the Direct Out jack to route signal to an external amplifier with a -10 dB input sensitivity.

* In-line effects (such as footpedals) intended for low signal levels should be placed between the bass and the amplifier Input and not connected with the Effect Send and Return jacks.

** Note that the settings of the ten-band graphic equalizer will affect a “Post” Direct Out signal regardless of the position of the front panel In/Out switch.

Setting Up and Using the Model 3500/5500

PASSIVE

ACTIVE

Setting up your Hartke Systems 5500 Bass Amplifier is a simple procedure which takes only a few minutes:

1. Remove all packing materials (save them in case of need for future service) and decide where the amplifier is to be physically placed. To avoid potential overheating problems, be sure that the rear panel is unobstructed and that there is good ventilation around the entire unit, particularly behind the rear-panel fan.

ENGLISH

2. Begin by hooking up your bass cabinet or cabinets, using the 1/4” unbalanced Speaker output connectors on the rear panel; it is never a good idea to power up any amplifier that is not connected to loudspeakers. We recommend the use of a single 4 ohm cabinet or two 8 ohm cabinets. Hartke amps are optimized for use with Hartke bass cabinets, although other brands of speakers can be substituted. Any appropriately rated bass cabinet with a minimum impedance of 4 ohms (that is, 4 ohms or greater) can be used. In order to ensure correct phase correlation, the tip of the Model 3500/5500 speaker jack should be connected to the “+” (hot) input of your loudspeaker, and the sleeve of the Model 3500/5500 speaker jack should be connected to the “-” (ground) input of your loudspeaker.

WARNING: Hartke amplifiers can deliver very high power levels. Driven to full power, they can damage connected loudspeakers, regardless of brand, size, or configuration. Care should be taken not to strain connected loudspeakers as this can cause permanent damage and will degrade the performance of the entire system. If you see connected loudspeakers moving excessively, turn your system down immediately or use the equalization and/ or compression controls to reduce the amount of subharmonic (extremely low frequency) signal.

3. Next, connect the 3-pin AC plug into any grounded AC socket. Don’t turn the amplifier on just yet, though.

4. Use a standard music instrument cable to connect your bass to the appropriate Input jack on the front panel (if your bass has active circuitry,* connect it to the “Active” input; if not, connect it to the “Passive” input). On the front panel of the Model 3500/5500, set the Master volume control to “0” (fully counterclockwise) and set both Pre-Amp A (Tube) and B (Solid State) knobs to “5” (the twelve o’clock position). Set the Compression knob to its “Off” position (fully counterclockwise—you’ll hear a click) and set both Contour knobs to their center detented “0” position. Finally, set the graphic equalizer In/Out switch to its “Out” position.

5. Press the front panel Power switch in order to turn on the amplifier. After approximately three seconds, you’ll hear a click, indicating that the relay protection circuitry has completed cycling and that power to the system has been provided.

6. Set the output of your bass to maximum and then, while playing, slowly turn the Master volume control up until the desired level is achieved. If you hear distortion even at low amplifier Master volume settings, back off the output of your bass (or check for a faulty cable).

* Bass guitars that have active circuitry normally require a battery for the circuitry to be functional.

7. Experiment with altering the balance of the two Pre-Amp knobs, listening to the effect each has on the overall sound. Depending upon the specific instrument you are using and your personal taste, you may prefer the sound of one over the other, or you may prefer a particular blend of the two. Note that, when both are used at equal settings, the amplifier will be twice as loud as when only one is used. In step #4 on the previous page, we recommended that you begin with both knobs at their midway “5” setting, but the two Pre-Amp knobs can in fact be set to any blend you like. However, you will usually want to avoid setting both to their maximum “10” position since this setting will almost always result in undesirable distortion.

8. When you have settled on a Pre-Amp balance, the next step is to adjust the two Contour (bass and treble equalizer) controls to taste. For more information, see the “About Equalization” section on page 10 of this manual. When you get a great setting that complements your instrument and playing style, it’s a good idea to write it down for future use.

9. Next, experiment with the Model 3500/5500 graphic equalizer. Begin by setting each of the ten sliders to their flat “0” center detented position. Then press in the In/Out switch (to its “In” position) so that the graphic equalizer is activated. Finally, move each slider in turn as you play your bass. For more information, see the “About Equalization” section on page 10 of this manual. Again, when you get a graphic equalization setting that complements your instrument and playing style, it’s a good idea to write it down for future use.

10. Now try out the Model 3500/5500 compression circuitry. Activate it by turning the Compression knob clockwise from its “Off” position (you’ll hear a click when it is activated). As you turn the knob clockwise, the input signal from your bass becomes more and more severely compressed—you’ll hear peak signals (such as string slaps and pulls) begin to sound increasingly “squashed,” relative to the lower-level signals produced by standard playing. The result will be a decreased dynamic range but an overall leveling of signal throughout the full pitch range of your instrument. For more information, see the “About Compression” section on page 12. In the Model 3500/5500, the Compression LED will light steadily green when no compression is being applied, will go out whenever small amounts of compression are being applied and will flash or light steadily red when limiting (severe compression) is being applied.

11. If you’re using an external signal processor, turn your Hartke amplifier off momentarily and then connect a standard audio cable between the Effect Send jack and your effects processor input and another standard audio cable between the Effect Return jack and your effects processor output (if required, multiple effects processors can be daisy-chained together, output to input). Start with the effect Balance knob at its center detented “0” position, so that you hear equal amounts of both the send and return signal.* Then turn the amp back on and play your bass while adjusting the controls of your outboard effects processor(s). For best results, set both the input and output gain of all connected effects processor(s) to 0 dB (unity gain), so that there is no increase or decrease in level whether the effects are switched in or out.

If you have followed all the steps above and are still experiencing difficulties, call Samson Technical Support (516-932-1062) between 9 AM and 5 PM EST.

ENGLISH

The Hartke Systems Model 3500/5500 Bass Amplifier gives you enormous control over shaping the sound of your bass, using a process called equalization. To understand how this works, it’s important to know that every naturally occurring sound consists of a broad range of pitches, or frequencies, combined together in a unique way. This blend is what gives every sound its distinctive tonal color. EQ controls allow you to alter a sound by boosting or attenuating specific frequency areas—they operate much like the bass and treble controls on your hi-fi amp, but with much greater precision. The Model 3500/5500 provides you with two different means for equalizing your bass sound:

• Low Pass and High Pass Contour controls provide 18 dB of cut or boost in two broad frequency bands.

• A Graphic Equalizer provides 15 dB of cut or boost in ten narrow fre

quency bands.

Normally, you will adjust the two Contour controls before “fine-tuning” your EQ with the Graphic Equalizer. The Low Pass Contour control affects a broad band of frequencies with 100 Hz as the center point; similarly, the High Pass Contour control affects a broad band of frequencies with 10 kHz as the center point. When either is in its center detented position (“0”), it is having

Contour controls

no effect. When it is moved right of center, the particular frequency area is being boosted; when it is moved left of center, the frequency area is being cut (“attenuated”). Because there is very little bass guitar energy at 10 kHz, the High Pass Contour control should be thought of as your overall “noise” control—turning it down (to the left of the “0” position) will help to eradicate hiss and buzz while having very little effect on the bass guitar signal. Similarly, the Low Pass Contour control, when set left of 0, can be used to eliminate rumble and “woofiness.”

The ten-band graphic equalizer provides ten sliders, each corresponding to a single narrow frequency band (at 30 Hz, 64 Hz, 125 Hz, 250 Hz, 500 Hz, 1

Graphic equalizer

kHz, 2 kHz, 3 kHz, 5 kHz, and 8 kHz). This allows you to “draw” the desired tonal response of your system. When a slider is in its center detented position (“0”), it is having no effect. When it is moved above center (towards “+15”), the particular frequency area is being boosted; when it is moved below center (towards “-15”), the frequency area is being attenuated. We carefully selected these frequency areas because they have maximum impact on bass signals. For example, the lowest slider (30 Hz) affects the very lowest audible frequencies (in fact, most humans cannot hear below 20 Hz), while the highest four sliders (2, 3, 5, and 8 kHz) affects the “twang” of a bass string.

WARNING: Use caution when raising the 30 Hz slider above 0 if you are operating at high volume levels (especially if Compression is not being used) since this can place undue stress on connected loudspeakers.

ticular bass, start with all ten bands flat (that is, all ten sliders at their detented “0” center position). Then, one by one, raise and lower each slider, listening carefully to the effect of each. If you don’t specifically need to utilize the ten-band graphic equalizer, bypass it by setting the In/Out switch to its “Out” position. Alternatively, you can preset a custom graphic equalization curve (for example, for a feature solo) and activate it simply by pressing the switch when needed. Note that turning all EQ controls up the same amount will have virtually the same effect as simply turning up the Master Volume; conversely, turning them all down the same amount will have virtually the same effect as turning down the Master Volume. Both approaches are pointless (after all, that’s why we gave you a Master Volume control!)

In many instances, the best way to deal with equalization is to think in terms of which frequency areas you need to attenuate, as opposed to which ones you need to boost. Be aware that boosting a frequency area also has the effect of boosting the overall signal; specifically, too much low frequency EQ boost can actually cause overload distortion or even harm a connected speaker, though the Model 3500/5500’s compression circuitry—if on—will act to some extent to prevent this from occurring. In general, if you’re going to apply a fair amount of low frequency EQ boost, it’s a good idea to keep Compression on, if only to protect your speakers from potential damage.

About Equalization

ENGLISH

The specific EQ you will apply to your bass signal is very much dependent upon your particular instrument and personal taste and playing style. However, here are a few general suggestions:

• For that super-deep reggae or Motown sound, boost low frequen cies slightly while attenuating the highest ones (leave mid-range frequencies flat or slightly attenuated), as shown in the illustration on the right.

• To remove boxiness and make your instrument sound more “hi-fi,” try attenuating mid-range frequencies while leaving low and high frequency settings flat, as shown in the illustration on the right.

• For a twangy, cutting sound, try boosting the high and high midrange frequencies, as shown in the illustration on the right (putting new roundwound strings on your bass will help a lot also!)

• Whenever you get a really good EQ setting for a particular instrument or song, write it down (you’d be amazed how easy it is to for-

settings—this can be particularly effective in instruments that have active circuitry. Also, try various EQ settings with different Pre-Amp blends and with and without Compression. For more information, see the “About Compression” section on the following page.

Model 3500/5500

Compression control and LED

The dynamic range of a sound is the difference between its loudest and softest points. For example, as you play your bass, you’ll probably find that some notes (for example, notes played on the upper frets of the lowest string) are considerably louder than others. The function of the Compression circuitry in the Model 3500/5500 Bass Amplifier is to reduce overall dynamic range by automatically reducing the level of the loudest sounds you play so that they are closer in level to softer ones—the end result is that the sound “evens out” and all notes played have pretty much the same level.

The front-panel Compression control determines the amount of compression (peak signal reduction) by simultaneously adjusting both threshold and compression ratio (which ranges from 2:1 to infinity [limiting]). At the fully counterclockwise “Off” position, the circuitry is bypassed and no compression is applied (the knob clicks when set to the “Off” position). As the knob is raised clockwise (at settings from “1” to “∞”) increasing amounts of compression is applied. At the highest settings, loud sounds will not just be compressed, but limited, where the output remains virtually constant regardless of input.

The Model 3500/5500 provides a front-panel Compression LED which acts as a useful visual indicator of the continuous activity of the compression circuitry. When lit steadily green (for example, when the Compression knob is set to “Off”), no compression is being applied. When unlit, compression is being applied to the incoming signal at a ratio of approximately 2:1. When flashing red, the compression ratio is approaching infinity (limiting is being applied). When lit steadily red, the signal is being limited. This LED “follows” the incoming signal, changing continuously as different amounts of compression and/or limiting are being applied.

Compression has three main uses. First, as just described, it “evens” out the notes played by your bass so that they all appear at virtually equal level. Second, it adds “punch” to a sound; since all levels are nearly the same, you can play with greater force without worrying about the loudest notes distorting. Finally, it serves to protect your loudspeakers from damage as a result of brief (transient) high output levels, as might be caused by finger-popping or other performance techniques.

Whether or not you need to use compression with your Model 3500/5500 will be a matter of personal taste and playing style—experiment and see if you like the effect. If you usually play at low volume levels, you’ll find that, even with the Compression knob turned up, the compression circuitry may have no audible effect, so it might as well be off. In general, if you don’t need compression, leave it off.

Le niveau de sortie est d'environ 0 dB à +4 dB et il est prélevé post-égalisation et post-compression, et n'est pas affecté par le réglage de Master Volume. Vous pouvez aussi utiliser le Jack Effect Send pour diriger le signal vers une console de mixage ou un amplificateur externe avec une sensibilité d'entrée de +4 dB.

6. Jack Effect Return - Utilisez ce Jack 6,35 mm asymétrique à basse impédance (600 Ohms) ) pour injecter le signal de votre processeur externe* à l'amplificateur 3500/5500.

7. Réglage de Balance - Utilisez ce bouton pour régler l'équilibre entre le départ d'effets Send (signal non traité) et le retour Return (signal traité) dans les hautparleurs de l'amplificateur 3500/5500. En position centrale “0”, le signal traité est de même niveau que celui du signal non traité. En position minimale (“Send”), le signal traité par le processeur externe n'est pas transmis à l'ampli. En position maximale (“Return”), le seul signal que vous entendez est celui du processeur externe. Si votre processeur d'effets externes est équipé d'un réglage signal traité/ non traité, réglez le bouton Balance au maximum (position “Return”) et utilisez le réglage signal traité/non traité du processeur pour mélanger les signaux. Vous pouvez également régler le processeur sur un signal totalement traité et utiliser le bouton Balance de l'ampli 3500/5500 pour doser les signaux.

8. Touche Direct Out Post/Pre - Lorsque la touche est enfoncée (position “Pre”), le signal est routé vers la sortie Direct Out avant d'attaquer l'égaliseur graphique du 3500/5500 (mais après le compresseur et les réglages Contour). Lorsque la touche est relâchée (position “Post”), le signal est routé vers la sortie Direct Out après les circuits de compression et d'égalisation (égaliseur graphique et réglages de Contour).** Utilisez la position “Pre” pour que l'ingénieur du son de la console puisse contrôler la sonorité de votre basse ; utilisez la position “Post” si vous souhaitez que le signal en entrée de la console soit traité par l'égaliseur graphique.

9. Touche Direct Out Normal/Ground Lift - Lorsque la touche est enfoncée (position “Gnd. Lift”), la broche 1 est découplée de la masse. Utilisez cette position uniquement en présence de ronflement ; sinon, laissez la touche en position relâchée (“Normal”).

10. XLR Direct Out - Utilisez cette embase symétrique XLR pour router le signal de l'ampli 3500/5500 vers une console de mixage professionnelle. Cette sortie basse impédance (100 Ohms) et un niveau de sortie compris entre -30 et -20 dB. Vous pouvez également utiliser la sortie Direct Out pour la connexion à un amplificateur externe avec une sensibilité d'entrée de -10 dB.

* Les effets en série (comme les pédales) sont prévus pour des signaux à faible niveau et doivent être insérés entre la basse et l'entrée de l'amplificateur. N'utilisez pas les connexions Effect Send et Return.

** Remarquez que les réglages de l'égaliseur graphique à 10 bandes affectent le signal Direct Out “Post”, quelle que soit la position de la touche In/Out de façade.
