Marshall DSL100HR Guitar AmpManuale utente della testa lifier

1. Introduzione

Thank you for choosing the Marshall DSL100HR Guitar Amplifier Head. This 100-watt all-valve amplifier head is designed to deliver a wide range of classic Marshall tones, from pristine cleans to high-gain distortion. It features two footswitchable channels, Classic Gain and Ultra Gain, each with two modes, providing four distinct sounds. Additional features include dedicated resonance control, two master volume controls, digital reverb, high and low power settings, and a Softube emulated output for direct recording or silent practice.

This manual provides essential information for the safe and effective operation of your DSL100HR amplifier. Please read it thoroughly before connecting or operating the unit.

2. Istruzioni di sicurezza

To prevent electric shock, fire, or damage to the amplifier, always observe the following safety precautions:

• Alimentazione elettrica: Collegare il amplifier only to an AC power supply of the voltage specified on the rear panel. Ensure the power cable is in good condition and properly grounded.
• Ventilazione: Non bloccare le aperture di ventilazione. Assicurare un flusso d'aria adeguato attorno all' amplifier per evitare il surriscaldamento.
• Umidità: Non esporre il ampProteggere l'unità da pioggia, umidità o umidità eccessiva. Tenere i liquidi lontano dall'unità.
• Manutenzione: Non tentare di riparare il amplifier yourself. Refer all servicing to qualified service personnel. High voltages sono presenti all'interno del amplifier, even when switched off.
• Collegamenti degli altoparlanti: Collega sempre il amplifier to a suitable speaker cabinet with the correct impedance before powering on. Operating without a speaker load can damage the output transformer.
• Tube Heat: Vacuum tubes operate at high temperatures. Avoid touching them and allow sufficient cooling time after use.
• Protezione dell'udito: Questo amplifier can produce high sound pressure levels. Prolonged exposure to high volumes can cause permanent hearing damage. Use appropriate hearing protection.

3. Impostazione

3.1 Disimballaggio

Rimuovere con attenzione il file amplifier from its packaging. Retain all packaging materials for future transport or storage. Inspect the amplifier for any signs of damage incurred during shipping. If damage is found, contact your dealer immediately.

3.2 Connecting to a Speaker Cabinet

The DSL100HR requires connection to an external speaker cabinet. Ensure the speaker cabinet's impedance matches one of the amplifier's output jacks (16 Ohm, 8 Ohm, or 4 Ohm). Use a high-quality speaker cable (not a guitar cable) for this connection.

• For a single 16 Ohm cabinet, connect to the '16 Ohm' jack.
• For a single 8 Ohm cabinet, connect to one of the '8 Ohm' jacks.
• For two 16 Ohm cabinets, connect each to an '8 Ohm' jack.
• For a single 4 Ohm cabinet, connect to one of the '4 Ohm' jacks.
• For two 8 Ohm cabinets, connect each to a '4 Ohm' jack.

Importante: Non azionare mai il amplifier without a speaker load connected to the appropriate output jack.

3.3 Collegamento di alimentazione

Connect the supplied power cable to the IEC inlet on the rear panel of the amplifier and then to a grounded mains power outlet.

3.4 Collegamento di una chitarra

Connect your guitar to the 'INPUT' jack on the front panel using a standard instrument cable.

3.5 Collegamento del pedale

Connect the supplied footswitch to the 'FOOTSWITCH' jack on the rear panel. This allows remote switching between channels and reverb on/off.

4. Istruzioni per l'uso

4.1 Accensione/Spegnimento

1. Assicurarsi che tutti i controlli del volume siano impostati al minimo.
2. Switch the 'POWER' switch to the ON position.
3. Wait approximately 30-60 seconds for the tubes to warm up, then switch the 'STANDBY' switch to the ON position. The amplifier è ora pronto per l'uso.
4. To power off, reverse the sequence: 'STANDBY' to OFF, then 'POWER' to OFF.

4.2 Controlli del pannello frontale

The DSL100HR features a comprehensive set of controls:

• Classic Gain Channel:
  • Volume: Controls the output level of the Classic Gain channel.
  • Guadagno: Regola la quantità di pre-amp gain for the Classic Gain channel.
  • Clean/Crunch Switch: Selects between a clean tone and a crunchy overdrive within the Classic Gain channel.
• Ultra Gain Channel:
  • Volume: Controls the output level of the Ultra Gain channel.
  • Guadagno: Regola la quantità di pre-amp gain for the Ultra Gain channel, from aggressive crunch to searing lead tones.
  • OD1/OD2 Switch: Selects between two different overdrive voicings within the Ultra Gain channel.
• Equalization (Shared):
  • Acuti, Medi, Bassi: Standard tone controls to shape the amplifier's frequency response.
  • Presenza: Adds high-end sparkle and cut to the overall sound.
  • Risonanza: Adjusts the low-end response and depth of the amppiù vivace.
• Cambiamento di tono: A push-button switch that re-configures the amplifier's EQ for a more modern, mid-scooped sound.
• Riverbero: Controlla il livello dell'effetto riverbero digitale incorporato.
• Master Volume 1 & 2: Two independent master volume controls allow for different overall output levels, useful for solos or rhythm sections. These can be switched via the footswitch.
• Interruttore alta/bassa potenza: Reduces the amplifier's output power from 100W to 50W, allowing for lower volume operation while maintaining tube tone.

4.3 Collegamenti del pannello posteriore

• Uscite altoparlanti: Multiple jacks for connecting speaker cabinets with various impedance ratings (16 Ohm, 8 Ohm, 4 Ohm).
• Ciclo FX (Invia/Ritorno): Allows connection of external effects pedals or processors. The FX loop can be bypassed.
• Uscita emulata Softube: A 6.35mm jack providing a direct, cabinet-emulated signal for recording or connecting to a PA system.
• Ingresso MIDI: For external MIDI control of ampfunzioni lifier.
• Interruttore a pedale: Connects the supplied footswitch for remote control of channels and reverb.

5. Manutenzione

5.1 Sostituzione del tubo

The DSL100HR uses 4 x ECC83 preamp tubes and 4 x EL34 power tubes. Tubes have a finite lifespan and will eventually need replacement. Symptoms of worn tubes include loss of volume, reduced tone quality, excessive noise, or intermittent operation. Tube replacement should ideally be performed by a qualified technician, as it involves working with high voltages and proper biasing of new power tubes is crucial for optimal performance and longevity.

5.2 Pulizia

Pulisci il amplifier's exterior with a soft, dry cloth. Do not use abrasive cleaners, solvents, or waxes. Ensure the amplifier sia scollegato prima della pulizia.

5.3 Conservazione

Quando non viene utilizzato per lunghi periodi, conservare il amplifier in a dry, temperature-controlled environment, away from direct sunlight and extreme temperatures. Using a protective cover can help prevent dust accumulation.
