DynaBlock 400 Bass Guitar Amplifier
DynaBlock400H/112/115/210
Thank you for choosing the DynaBlock 400. You will discover that this bass amplifier has
the ability to sound “right” with a minimum amount of knob twirling and delivers great tone
making it perfect for your any performance. Best of all its lightweight, compact design will
make setups/teardowns a great deal easier.
When you need the extras, they’re all here:
• Dual Inputs are provided for standard Passive pickups (0 dB) and extra-hot or
Active pickups (-9 dB).
• The power on light will illuminates much brighter RED if the input signal is too hot
from your bass.
• Gain and Master controls let you dial-in the perfect amount of clarity, warmth or even
overdrive at the right level.
• The Low expander control lets you tailor your sound precisely and uniquely by extending
the lows while reducing the midrange.
• Active Bass, Low-Mid, Hi-Mid and Treble tone controls provide up to 15dB of cut or boost
• A separate Tuner Out jack lets you keep your tuner connected without affecting your signal
quality. This also makes tuning convenient since it’s always available for quick reference
and adjustments. Using the Mute button ensures that the audience doesn’t hear you tuning.
• The balanced XLR Line Out is selectable via rear-panel pushbutton between Pre-EQ
(dry) or Post-EQ (wet).
• Two Speakon™ combo jacks Speaker Outputs are provided for your convenience. All
jacks are in parallel and the overall minimum load is 4 ohms.
• The Phones jack permits connecting headphones for silent practicing, or
monitoring yourself in the studio
• Balanced ¼-inch Efx Send and Return jacks
• A full-range speaker system with acoustically matched and precisely crossed-over low
and high-frequency drivers (DynaBlock combos only)
• A Tweeter Defeat/Active switch on the back of the cabinet allows you to pre-set the
DynaBlock 400 for higher note definition or a softer vintage sound (DynaBlock Combos only)
