Rocktron Blue Thunder - Manual (Page 4)

1. Introduction
Congratulations on your purchase of the Rocktron Blue Thunder ™ bass Preamp and effects processor! The Blue
Thunder has been specifically designed and voiced for bass. The Blue Thunder is a live and studio tool that is a “must
have” for all bass players. 24-bit DSP processing via a Motorola DSP engine provides a host of high quality digital
effects.
• Selectable Hi Pass Filter Section - The Blue Thunder has a built-in Hi-Pass filter section before the effects
processing chain allows the user to choose one of four frequency (80Hz, 160Hz and 240Hz, 320Hz) cutoff points.
This allows lush effect mixing while maintaining everything below the selected cutoff point to be left un-effected.
The result is effects that leave the bottom end tight and punchy.
Example - when 160Hz Hi-Pass is selected, all signal content above 160Hz is passed into the effect processing
chain. When the direct (original) signal is mixed back in with the effected signal using the Blue Thunder’s mixer
section, the frequencies below 160Hz will remain virtually un-effected.
• Built-in Distortion - The Blue Thunder has built-in distortion that has been custom voiced for bass. The advance
processing power of the Blue Thunder allows you to dial in just the right amount of distortion without effecting
your overall clean tone.
• Run up to 10 effects at once - The advanced processing power of the Blue Thunder will allow you to run up to 10
high quality effects at the same time.
• High quality digital effects include - Distortion, multi-voiced delay and chorus, tremolo, flanger, reverb, phaser,
HUSH, compressor, speaker simulator, speaker modeling and mic position modeling
• Ultra transparent processing - the cleanest and most clear effects around. Rocktron’s direct signal routing allows
for mixing the direct signal with the effected signal to reached the desired effect.
• Pre-loaded with 128 professional presets custom designed for bass. Presets 1-64 are meant for live situations.
Presets 65-128 are designed for recording or direct connection situations. However, all presets can be used in any
situations and are completely user definable.
• Preset Spillover allows for reverb and delays from a current preset to carry over into the next preset and continue
decaying when a new preset has been selected.
• Real Time Control of delay times and modulation rates through tap tempo and rate parameters. Delay times and
modulation rates can be changed instantly by tapping the tap switch on the front panel or through the use of the
Rocktron All Access or MIDI Mate footcontrollers.
• HUSH ® noise reduction operates only on incoming preamp noise, and does not affect the digital effects - which are
already ultra quiet.
• Rocktron’s SIMBiotic ™ EQ - is a custom designed EQ circuit providing the ultimate tool for tonal shaping of your
sounds. It includes four band full parametric EQ and complete mixing capabilities.
• Speaker Exciter - Adds a completely new dimension to your sound and tone in live and recording situations. It
enables you to modify the characteristics of your exisiting speaker cabinet allowing you to emulate different size
speakers and tonal response.
• Cabinet SIM - Allows you to record direct or plug directly into a PA system - eliminating the need to carry a heavy
amplifier to the gig! The Cabinet SIM is a special fequency response curve that re-creates the natural average
frequency response curve found with Bass speaker cabinets. Using the Speaker Exciter along with the Cabinet SIM
is the ultimate sound shaping tool for direct, live and recording situations.
