User manual MARSHALL MG50DFX

[. . . ] For example, the power amp section of your new combo boasts FDD (Frequency Dependent Damping) ­ a radical new feature that is exclusive to Marshall Amplification and accurately mimics the way our all-valve amplifiers interact with a loudspeaker. As a direct result of FDD, your new MG50DFX/MG250DFX will give you a sound and feel never before thought possible in such an affordable, non-valve amp. The DFX (Digital Effects) featured in both the MG50DFX and MG250DFX have been custom voiced by our in-house digital effects experts. Each one of the five effect types on offer (Chorus/Delay, Delay, Chorus, Flange and Reverb) have been designed to emulate the much sought after warmth and feel of analogue effects, but in a highly flexible digital format. [. . . ] This behaviour is exactly what a good all-valve amplifier does and is a result of our proprietary FDD circuitry. 7. OD LED When illuminated, this LED indicates that the Overdrive Channel has been selected by either the Channel Select switch (6) or the supplied two-way footswitch. 2. Clean Channel GAIN control When the Clean Channel is selected, this control adjusts its volume. At low settings the sound will be very clean with a pleasing, bell-like ring. Turning this control above half way will introduce a desirable, bluesy distortion as the power amplifier stage is driven into `crunch mode'. 13. Digital FX PRESET / ADJUST control This control serves a dual purpose. Not only does it allow you to select one of the four types of effects on offer (Chorus / Delay (CHR/DLY), Delay (DLY), Chorus (CHR) or Flange (FLG)), it also allows you to adjust a parameter as you sweep it through each of the four effect segments. The parameter you can adjust for each of the four effect segments is shown below: 8. Overdrive Channel GAIN control Turning up the Gain control will increase the amount of preamp distortion generated in the Overdrive Channel. Low Gain control settings will produce classic rock and blues tones. Crank this control for fat and aggressive sounds that are perfect for soloing or hard rock and nu-metal riffing. 3. Clean Channel BASS control Turning up the Bass control will add warmth and low-end depth to your clean sound. The Bass control can be used in conjunction with the FDD switch (17) to produce deep sounding, valve-like clean tones that are well defined yet still full and round. Effect Chorus and Delay (CHR/DLY) Adjustable Parameter Delay Time (from short to long as you turn the Preset/Adjust control clockwise through the CHR/DLY segment) Delay Time (from short to long as you turn the Preset/Adjust control clockwise through the DLY segment) Speed (from slow to fast as you turn the Preset/Adjust control clockwise through the CHR segment) Speed (from slow to fast as you turn the Preset/Adjust control clockwise through the FLG segment) Description This multi-effect combines a lush, fixed speed Chorus with a variable time Delay. 9. Overdrive Channel BASS control Turning up this control will add extra low-end `thump' to high gain riffs and a warm, natural sounding depth to lower gain crunch tones. Using the Bass control in conjunction with the FDD switch (17) will allow you to dial in the exact amount of low-end `thump' and tightness you are looking for. 4. Clean Channel MIDDLE control Adjusting the middle frequencies in your clean channel will vary the amount of body to your sound. Attenuating (decreasing) the middle by turning this control anticlockwise will yield a more hollow sound with the bass and treble frequencies appearing to be more accentuated. Conversely, increasing the middle will add body to the Clean Channel's sound. Delay (DLY) 10. Overdrive Channel CONTOUR control This highly effective tone control works by radically modifying the mid-range (body) of your sound. The tone can vary from traditional and woody sounding (control set at 0), to balls-to-thewall (control set midway), to aggressive, `scooped' and modern (turned up to 10) and all points inbetween. Chorus (CHR) Short Delay Times will have less repeats for `groovy' surf and rockabilly tones. Increasing the Delay Time increases the number of repeats for a much more atmospheric, `stadium' effect. 5. [. . . ] So after setting-up the relative volume of Channels 1 & 2 the overall level can be adjusted without affecting your all-important Clean/Overdrive balance. 19. POWER Switch & LED The power switch turns your amplifier on and off. The LED will be lit when your amplifier is on and will not be lit when the amplifier is switched off.
