Siege Engine Bass Amplifier
Owner's Guide
Lay siege to your enemies with the successor to the Bass 701 amp. The Siege Engine is a
compact but powerful bass weapon with a TON of o erdri e on tap and massi e flexibility to shape
your tone. The pre amp features a 6 band EQ and o erdri e section that allows you to carefully tailor
the gain and tone. The power amp has 700 watts of power to deli er that tone.
•Input and Pre Gain:
The jfet input amp feeds directly into a Pre Gain control that can be
pushed hard to introduce some dri e or kept clean, which in turn feeds the o erdri e section.
•Overdrive: In the o erdri e section the signal is split into Deep, Bass, Lo Mid, Mid, Hi Mid
and Treble frequency bands. Each band has a Le el control and each band has it’s own Dri e
control except for the Deep band so your low end is kept completely clean and intact. All the
bands are summed back together to form a harmonically rich tone that still maintains the
integrity of all the notes you're playing. There is a wide range of dri e that can be applied to
each frequency band as well as adjusting the indi idual band’s le el.
•Footswitc : Turn the o erdri e section or the effects loop on or off indi idually with the two
button footswitch or the selector rotary switch on the front panel.
•700 Watt Power Amp: The class D power amp can deli er 700 watts of power.
•Balanced Line Output: XLR and unbalanced 1/4” jacks to connect to mixing consoles or
other amplifiers.
•Headp one Output: Connect headphones to use the amp for practice with an aux input.
•Universal Power: Can accept 100 to 240 Volts AC, 50 to 60 Hz.
•Compact Size: 11” x 3” x 8” and comes with a carrying case.
Front Panel
In: 1/4” jack to connect to an instrument.
Standby: In the on position the red LED turns green and all the outputs are acti e. The tuner
output is acti e in either position.
-12dB Pad: In the down position this toggle switch attenuates the input signal by 12dB, for use
with acti e basses or instruments with ery high output le els.
Pre Gain: After the jfet input amp the signal is sent to the Pre Gain control which can be pushed
hard or kept clean, regardless of whether the o erdri e section is on or off. This also sets how hot
the signal being fed to the o erdri e can be, which in turn will affect the tone.
Selector Rotary Switc : You can turn the o erdri e section or the effects loop on or off
indi idually with the two button footswitch or the selector rotary switch on the front panel. The
positions for the selector rotary switch are Dry (no o erdri e or effects loop), OD (o erdri e only), FX
(effects loop only), or OD>FX (the o erdri e section feeds into the effects loop send). When the
footswitch is connected it o errides the selector rotary switch.
Overdrive Section
In the o erdri e section the instrument signal is split into Deep, Bass, Lo Mid, Mid, Hi Mid and Treble
frequency bands. The purple LED indicates when the O erdri e section is engaged.
Deep: This sets the output le el of the Deep band but has no o erdri e so your low end is kept
completely clean and intact.
Bass, Lo Mid, Mid, Hi Mid and Treble: Sets the output le el of each of these frequency bands.
These frequency bands also ha e indi idual Dri e controls which sets how much o erdri e is applied
to that particular frequency range.
Volume: All the bands are then summed back together to form a harmonically rich tone that still
maintains the integrity of all the notes you're playing with the output le el being set by the Volume
control.
Hi Cut: The hi cut controls works on the summed o erdri e signal to tame the possibly huge
amounts of harmonics generated by mixing all the o erdri es together.
Effects Loop
The effects loop comes after the O erdri e section and can be switched on or off by using the
footswitch or the selector rotary switch on the front panel. There is a red LED indicating whether the
effects loop is on or off below the selector rotary switch.
The effects loop Send and Return jacks are on the back panel, along with a Send Le el control, for
adjusting how hot the send to any effects units are.
Master Section
The master section is the final stage before the power amp controlling the master olume and bass
and treble on the output signal.
Bass: Bass shelf control with 15dB of boost or cut. At the noon position there is no change to the
signal. With the treble control this forms a Baxandall type tone stack.
Treble: Treble shelf control with 15dB of boost or cut. At the noon position there is no change to
the signal.
Master Volume: Output olume sent to the power amp only.
Back Panel
Headp ones
Connect headphones to use the amp for practice with an aux line in for playing along to recorded
tracks.
Level: Sets the headphone olume of the bass amp sound.
Aux In: 1/8” jack to connect to a phone or MP3 player, or any other source of pre-recorded music.
You must set the olume for your aux in on whate er de ice is plugged into it.
P ones: Stereo 1/4” jack to connect to headphones.
Line Out
Send a signal out to mixing consoles, PA systems or other amplifiers.
XLR out: Connect a mic cord to send a balanced signal to mixers. DO NOT apply 48V phantom
power to this XLR line.
Unbalanced: Connect to an external amp using an unbalanced 1/4” instrument cable. For a
balanced output use the XLR out.
PRE / POST and GND lift: Rotary switch to select the signal output. In the Pre position the Line
Out signal is taken directly from the input of the amp. In the Post position the Line Out signal is
taken from the Master section which comes after the o erdri e and effects loop, before the Master
Volume but after the Bass and Treble controls.
To engage the ground lift if there is a ground hum issue on the XLR Out, use the third and fourth
positions of the rotary switch: Pre with GND lift, and Post with GND lift.
Tuner
Use this 1/4” jack to connect to a tuner. When the amp is on this output is buffered from the input.
When the amp is on standby it is taken directly from the input jack of the amp for silent tuning.
Effects Send and Return
1/4” jacks to connect to an external effects pedal or signal processor. If nothing is plugged into the
Return jack the signal is passed through from the Send. The Send Le el adjusts the output le el of
the Send jack.
Footswitc
Connect the included footswitch using a 1/4” TRS (stereo) cable, also included. The footswitch
o errides the function of the front panel selector rotary switch when it is attached. The LEDs on the
footswitch indicate whether the O erdri e section and/or the effects loop is engaged.
Speaker Outputs
The 1/4” jack and Speakon jack are wired in parallel to connect to speaker cabinets. The absolute
minimum load is 2.5 ohms but 4 ohms is recommended. The output power is 700 watts at 4 ohms or
350 watts at 8 ohms.
AC Power In
Use a grounded wall socket or power bar and the supplied AC cable to connect to AC power. The
power range can be from 100 to 240 olts AC, 50 to 60Hz. There is a fuse holder with a spare fuse
in the AC jack.
Recommended Settings
As a starting point we recommend setting all the o erdri e section's le els to noon and the dri es to
the same or a consistent lower le el. From there you can experiment with adjusting the pre gain to
quickly add or subtract the total gain, or indi idually adjust the o erdri e channels. To hear what
each o erdri e channel sounds like indi idually you will ha e to turn all the channel's le els down to 0
and then bring one up by itself. It may take a while to find your tone but it will be well worth it.
