Marshall DSL100HR Guitar Amplifier Head User Manual
INTRODUCTION
Congratulations on your purchase of this Dual Super Lead (DSL) amplifier from Marshall Amplification. The DSL provides the legendary Marshall tone, allowing you to express your distinct playing style and attitude. Your DSL amplifier has been designed specifically for those who need the full rich tone of a valve amp. This makes the amp ideal for a live environment, studio or at home thanks to the power reduction system. We hope you enjoy performing, practicing and recording with your DSL amplifier
OVERVIEW
- The DSL 100 Head and 40 Combo feature the same functions.
- The DSL features two foot switchable channels: CLASSIC GAIN and ULTRA GAIN. The CLASSIC GAIN channel delivers sparkling clean sounds through to the more aggressive break-up of a Marshall JCM800 amplifier.
- Both channels share a passive three-band EQ, with BASS, MIDDLE and TREBLE controls. The EQ section also features Tone Shift, which when activated reconfigures the pre-amp mid frequencies making DSL ideal for contemporary metal tones, especially when combined with higher gain settings.
- The DSL features professional quality digital REVERB and a series FX LOOP.
- For the most demanding players, the DSL 40 Combo and DSL 100 Head feature MIDI compatibility meaning outboard MIDI equipment can access all the features needed to perform
FRONT/REAR PANEL FUNCTIONS
- INPUT: Input jack socket for your guitar cable. Use a good quality screened/shielded guitar cable to help prevent noise interference.
- GAIN: Controls the gain level for the CLASSIC GAIN channel. As the amount of gain increases, so will the distortion level in your sound.
- MODE STATUS LED: This LED lights green to indicate that CLEAN mode is selected and red to indicate CRUNCH mode is selected.
- VOLUME: Controls the volume level of the CLASSIC GAIN channel.
- CLEAN/CRUNCH: Press to select CLEAN or CRUNCH mode. The CLASSIC GAIN channel’s two modes take your sound from clean to overdriven tones.
- GAIN: Controls the gain level for the ULTRA GAIN channel. As the amount of gain increases, so will the distortion level in your sound.
- MODE STATUS LED: This LED lights green to indicate that OD1 mode is selected and red to indicate OD2 mode is selected.
- VOLUME: Controls the volume level of the ULTRA GAIN channel.
- OD1/OD2: Press to select OD1 or OD2 mode. The ULTRA GAIN channel’s two modes go from an open, high gain overdrive to a mid-boosted tone with even higher gain possibilities.
- TREBLE: Controls the higher frequency content of your sound. Turning clockwise will increase the highs making the sound brighter and more crisp.
- MIDDLE: Controls the middle frequency of your sound. Turning clockwise adds girth.
- BASS: Controls the amount of lower frequency, or bottom-end, in your sound. Turning clockwise will increase the bottom-end making the sound fuller.
- TONE SHIFT: Tone Shift reconfigures the preamp EQ network adding a new dimension to tonal shaping.
- PRESENCE: Controls the amount of higher frequencies of your sound. Turn clockwise to add crispness and bite for a more cutting tone. PRESENCE is a power-stage function and acts independently of the preamp EQ controls.
- RESONANCE: Controls the amount of lower frequencies in your sound. Turning this control clockwise adds a resonant.
- REVERB CLASSIC: Controls the REVERB level of the CLASSIC GAIN Channel.
- REVERB ULTRA: Controls the REVERB level of the ULTRA GAIN Channel.
- MASTER SELECT: This switches between MASTER 1 and MASTER 2.
- MASTER 1: Controls the overall volume level of the amplifier when selected.
- MASTER STATUS LED: This LED lights green to indicate that MASTER 1 is selected and red to indicate MASTER 2 is selected.
- MASTER 2: Controls the overall volume level of the amplifier when selected.
- LOOP STATUS LED: This LED lights red to indicated that the FX LOOP is On.
- LOOP ON/OFF: This switch activates and deactivates the FX LOOP.
- OUTPUT: This three position rocker switch combines STB (standby) and HIGH/ LOW output power functions. The HIGH and LOW output functions allow the user to choose between two configurations of the internal power supply.
- POWER: Mains power ON/OFF switch.
- MAINS INPUT: Connects the amplifier to the mains electricity supply
- MIDI IN: Connect your external MIDI device to the MIDI IN socket.
- FX LOOP RETURN: Connect the output of an external FX pedal or processor.
- FX LOOP SEND: Connect the input of an external FX pedal or processor.
- F/S: Connect the supplied 2-way footswitch or the optional 6-way footswitch here.
- AUDIO IN: Connect an external device here to practice with or to jam along to music.
- EMULATED OUT: Emulated line level output for headphones or connection to a mixer. This ensures that your headphone and output signal from this socket provide the best possible tone for practice or recording
- LOUDSPEAKERS: There are five speaker outputs available.
- 1 x 16 OHM: connect a single 16 Ohm speaker cabinet to this jack.
- 1x 8 OHM or 2 x 16 OHM: connect a single 8 Ohm speaker cabinet or two 16 Ohm speaker cabinets.
- 1 x 4 OHM or 2 x 8 OHM: connect a single 4 Ohm speaker cabinet or two 8 Ohm speaker cabinets.
