WARP 7™! 21st century metal is all about detuned guitars, ponderous & ominous riffs, big & bold effected clean sounds. No wonder that yesteryear’s amplification can’t cut it in this brave new world of sound. The WARP 7™ is designed specifically to do the sound, vibe and feel of detuned guitars justice. No quarter expected, none granted. The WARP channel will hammer out every hard-as-nails riff you send its way. Its CLEAN channel also packs a mighty wallop; even the wildest effect sounds slice through loud and clear. Both channels sport dedicated 3-band EQs, letting you dial in great tone and extreme contrasts, from nasty, paint- peeling riffs to glassy & glossy clean arpeggios and chord work. With its beefy 100-watt power amp, the WARP 7™ is the ideal tool for winning friends and influencing people; particularly your neighbors and parents are sure to be delighted. The combo is loaded with Celestion

• Check out the voltage rating displayed next to the WARP 7™'s MAINS INPUT and make sure it matches your local mains current before you plug in.

• Make sure plenty of air can circulate around your amp's ventilation ducts.

• Place the amp on a sturdy, secure base and avoid exposing it to mechanical shocks and extreme temperatures that could endanger the device or your and others' safety.

• The manufacturer disclaims any liability or responsibility whatsoever for any damage or defect to this and other devices resulting from misuse. Warp_7 Manual 2.5 11.09.2002 10:17 Uhr Seite 5What’s so special about the design of the WARP 7™ circuitry? Well, there are two new wrinkles particularly worth noting:

1) The preamp is optimized for the signal and

frequency response of detuned guitars. The WARP 7™ just starts to unleash the brunt of its sonic fury at frequencies other amps can’t even begin to render. This big bad beast likes the taste of detuned riffs best, so be sure to feed it regularly!

2) WARP 7™ sports two channels that are, sonically

speaking, polar opposites: ultra clean vs. roaring high gain tone. And that calls for closer examination: CLEAN: The CLEAN channel delivers razor-sharp tone piercing enough to stop a charging rhino in its tracks at a hundred paces. The signal remains distortion-free even at a very high volume. Not until the Volume knob is cranked to the hilt will the amp begin to bare its teeth with a hint of snarl. Nice but nasty are the adjectives that come to mind. Now what’s so remarkable about that? In a nutshell, you can lather the wildest and weirdest effects on your guitar signal and it will still cut through loud and clear, with enough punch to put the rest of the band’s instruments in their place. Say goodbye and good riddance to those wimpy, washed-out sounds. Now you can play with the big boys’ toys - hip vibe, roto and tremolo effects of the variety used by the headlining acts - and still be heard at denture-rattling volume levels. WARP: CAUTION! This is the WARP 7™’s sonic heart of darkness. This channel offers the kind of earsplitting high gain sound that you have come to know and love from your fave CDs. Its distortion can be best be described as a throaty rumble - picture a genetically engineered, steroid-addled lion with an attitude problem. Depending on the setting, it delivers a nasty nu metal thump, post-grunge growl, alternative snarl or the doomsday thunder so cherished by devotees of death and Goth metal. The Presence knob tweaks the upper mids to suit each genre. Case in point: Gain all the way up, Bass cranked, Mid and High to 12 o'clock positions, Presence to 11 o'clock – presto, there’s that trademark "Bizkit" sound. Now you have some idea of what the WARP 7™ is able to deliver in terms of tone. But there’s more to it than that - you’ll find truckloads of our trademark Technology of Tone in the various connectors, buttons and knobs as well. And that’s our cue to look at these in detail:

Warp_7 Manual 2.5 11.09.2002 10:17 Uhr Seite 6INPUT: Input jack for guitars. It input sensitivity is designed to take guitars with even very high output levels, so feel free to slap this input silly with powerful signals. Totally bulletproof (in this respect, that is), it is built to take everything your guitar can dish out and more. CLEAN VOLUME: Determines the level of the CLEAN channel. Even at high settings, the amp’s output signal will remain virtually free of distortion. You may want to take pity on your band mates and hand out earplugs before the next rehearsal. BASS, MID, TREBLE: The CLEAN channel’s 3-band EQ. Again, this channel has oodles of headroom, delivering tremendous clarity and packing the kind of punch it takes to get heavily processed signals across load and clear. If you don’t use many effects, you’ll come up with the best results if you turn the BASS knob well up and the TREBLE knob to just to the left of the 12 o’clock position. Then adjust the MID knob to tune the tone to your guitar and taste. YELLOW WARP LED: Illuminates to indicate the CLEAN channel is active. CHANNEL SELECT: Switches from the CLEAN channel to the WARP channel. The WARP channel is active when the pushbutton is pressed. RED WARP LED: Illuminates to indicate the WARP channel is active. WARP GAIN: Controls the WARP channel’s saturation level. This knob is your grit selector: Go from merely dirty but tremendously punchy tone at lower settings to an evil roar at higher GAIN settings. WARP MASTER: Controls the level of the WARP channel; use it to dial in the desired balance bet- ween the CLEAN and WARP channels. If you want to send your band buddies home with bleeding ears, this is the knob to use. Witticisms aside, though: The WARP 7™ is a truly loud amp and your hearing is extremely sensitive. Please use common sense and exercise restraint with volume levels BASS, MID, TREBLE: 3-band EQ for the WARP channel. You’ll find an example setting in section

2.0 above describing the WARP channel.

PRESENCE: Fine-tunes the upper mids (1,100 to 1,800 hertz). This frequency range has a considerable influence on the overall flavor of your sound. The amount of “bite” varies depending on this knob’s setting. With a little experimentation, this knob will soon help you discover the sonic secrets of the big boys. FX-SEND: If you want to employ an effect device, connect this jack to the signal processor’s input. (More on this in section 4.2). You can also use this output to send the signal to another power amp or a RED BOX

for the purposing of patching your signal into a mixer. (More on this in section 4.3) FX-RETURN: Connect this jack to the effect device’s output. WARP 7 MANUAL

FS-1 will do nicely) for switching back and forth between the CLEAN and WARP channels. To do this, the CHANNEL SELECT switch on the front panel must be set to CLEAN (red LED does not light up). PHONES: Connect headphones to this jack. The head’s SPEAKER OUT is automatically disconnected when you insert a plug into this jack. On the combo, both the SPEAKER OUT and internal speaker are disabled, ensuring conciliatory relationships with landlords. REAR PANEL: MAINS: Connect the included Euro norm mains cable to this socket. Before you plug in the mains cord, ensure your local mains voltage matches the specification indicated on the device. SPEAKER OUTPUTS: Serial (combo): Designed to connect an auxiliary cabinet with a minimum impedance of 4 ohms. Unless of course you want to use the WARP 7™ one last time as a hot air grill, barbecuing it in the process. That’s an option we can’t advocate... Parallel (heads): Designed to connect to the included 4x12" cabinet and another auxiliary cabinet with a rating of at least 8 ohms. The minimum permissible impedance is 4 ohms. This means if you connect cabinets to both outs, each cabinet’s impedance may be no lower than 4 ohms! Unless of course…(see above)

Now that you know a bit about the key features, let’s take a look at how the WARP 7™ handles. This section also provides useful tips on connecting the WARP 7™ to other devices.

4.1 SELECTING CHANNELS

You can activate the channels of the WARP 7™ via the front panel CHANNEL SELECT button or an external footswitch. The HUGHES & KETTNER

range of accessories offers a footswitch that fits the bill, the FS 1.

4.2 THE WARP 7™ AND FX DEVICES

WARP 7™ is equipped with a serial effects loop. This means that the preamp output signal is routed through an inserted effect device in its entirety, and that the entire signal is processed. Please note that the sound quality of the processed signal depends largely on the quality of the employed effect device. A sorry signal processor can corrupt your tone.

• Connect the FX SEND jack to the input and the FX RETURN jack to the output of your effects device.

• Use high-quality patch cords only to avoid signal loss, background noise and drop-outs.

• Ensure that the effect device is not being over- driven. Keep an eye on whatever type of level meter, gain indicator or overload lamp the effects device is equipped with, and adjust its input and output controls accordingly.

• Unless you have a jones of lo-fi effects, distortion devices simply don’t belong in an FX loop. Any kind of device that compresses the signal should be connected first in the signal chain. Depending on the type of effect you want to achieve, it may be preferable to plug a compressor to the amp's input.

• Other stompboxes should also be plugged into the front panel input.

4.3 THE WARP 7™ AND AUXILIARY

POWERAMPS Connect FX-SEND (+ 6 dB output level with the power amp’s line input. This port’s output level is independent of the MASTER volume knob. -Again, use high-quality patch cords only to avoid signal loss, background noise and drop-outs.

4.4 THE WARP 7™ AND MIXING CONSOLES

When you want to connect the WARP 7™ to a mixer, we recommend that you patch the signal through a HUGHES & KETTNER

PRO first. Connect it to the amp’s FX SEND jack. Here too, the output level is independent of the MASTER knob setting. The RED BOX

balances the signal and simulates the sound of speakers. A RED BOX

may also be inserted between the speaker out and the speakers. In this scenario, the output level depends on the MASTER knob setting.

5.0 SERVICE AND PREVENTIVE

MAINTENANCE The WARP 7™ amp does not require any type of regular maintenance, and there are no user- serviceable parts inside. However, there are a few precautions you would be well-advised to take because they will extend the life of your amp tremendously:

• Make sure all peripheral devices, cords and cablesare in a state of good repair!• Defective speaker cables (shorted cables, looseconnections) are by far the most common cause ofpower amp failure. • Low-quality patch cords lack adequate shielding;they are noisy and often the source of annoying hum.• Ensure plenty of air can circulate around your amp'sventilation areas (that is, the back of the amp‘schassis) at all times.• Definitely avoid exposure to mechanical shocks andextreme heat, dust and particularly moisture.• Be picky about the kind of peripheral devices thatyou connect to your amp and always check out theirspecs before you plug them in. Never connectdevices with high output signal levels (e.g. poweramps) to your amp's input.• Be sure the AC power source delivers the current thatyour amp is designed to handle before you plug it in.When in doubt about the local rating, ask the venue'ssound technician or a stage hand.• Refrain from DIY repairs! Be sure to take your to anexperienced technician when internal fuses needreplacing.Use a soft damp cloth to clean the exterior surface ofthe WARP 7™.

6.0 POSSIBLE ERROR SOURCES/

• It‘s not getting AC power. Check the mains cable to see if it‘s connected properly!

• The mains fuse is defective. Replace it another fuse bearing the identical rating. If another defect occurs, please get in touch with your local HUGHES & KETTNER dealer.

• One or several GAIN or MASTER controls is/are turned all the way down. Dial in a higher setting.

• Your guitar cord may be defective; try another cord.

• A short circuit in the speaker signal chain may have tripped an internal fuse. Make sure none of the connections are shorted out and have a qualified service technician replace the fuse.

6.3 Your footswitch will not switch channels:

• The footswitch cord’s plug is not inserted pro- perly into the jack,

• Check if you connected a suitable footswitch. We recommend the FS-1, another great product of the HUGHES & KETTNER

range of accessories.

• An electrical or magnetic field is causing inter- ference. Use cables of a higher quality or rearrange the cables you are using to reduce interference to a minimum. If this still doesn't improve the situation, use a DI box.

• The connected devices’ ground circuit may be causing a ground loop. At least one device’s connection must be galvanically using a DI box or transformer. CAUTION: Under no circumstances should you sever the ground of the connected devices!

6.5 The signal is totally distorted when you

connect an FX device (even when you dial in a clean sound).

• The effector’s input is being overdriven. Decrease the processor‘s input sensitivity by backing off its input or gain knob.

6.6 The output signal level drops considerably

when you connect an effect device.

• The FX processor's output level is set to too low a level. Turn it up
