QUICK START INSTRUCTIONS
Get your Landmark 300 up and running before reading the entire manual. However,
by not reading the manual, you’ll miss getting the most out of your new investment!
1. Plug the Landmark 300 head into speaker cabinet(s). If you’re not using Tech 21’s
B410s, we recommend cabinets be rated for minimum of 300W RMS at 4Ω or 200W
RMS at 8Ω.
2. Plug the Landmark 300’s AC cord into a wall socket.
3. Plug your instrument into the front panel Input jack (on the left side).
4. Make sure the Level control on each channel is turned down. Then turn on the
Landmark 300 and adjust the Level controls accordingly.
5. Play your guitar and you should hear a sound coming through the amp. If not, check
that your guitar’s volume control is turned up, recheck your connections, and be sure your
cable isn’t faulty. If there is still no sound, refer to factory or qualified technician.

Tech 21, the Company
Landmark 300, an Overview
Tech 21, Inc., was formed by a guitarist possessing the unusual combination
of a trained ear and electronics expertise. In 1989, B. Andrew Barta incorporated Tech 21 and made his unique invention commercially available to players and studios around the world. His highly-acclaimed SansAmp™ pioneered Tube Amplifier Emulation in professional applications for recording
direct and performing live, and created an entirely new category of signal processing. While there have since been many entries into this niche, SansAmp
continues to maintain its reputation as the industry standard.
After developing a full line of SansAmp models, Tech 21 expanded its offerings to include effect pedals; a compact, battery operable MIDI footcontroller,
the MIDI Mouse; as well as “traditional” style amplifiers. Each product is
thoughtfully and respectfully designed by Andrew himself with the player in
mind. Our goal is to provide you with flexible, versatile tools to cultivate, control, refine and redefine your own individual sound. Tech 21 takes great pride
in delivering consistent professional quality sound, studio to studio, club to
club, arena to arena.
The Landmark 300 is a 2-rackspace, 300-watt version of its predecessor, the
Landmark 600. It offers the same truckload of the most desirable vintage and
modern tube amp sounds, including Fender®and SVT®styles, as well as a
variety of overdriven tones --the ones that typically require a complex mass
of effects that aren’t really designed for bass in the first place. The interactive controls give you access to specific tone shaping characteristics to create your own custom sounds as well.
For studio and live applications, our proprietary, 100% analog SansAmp
Tube Amplifier Emulation technology enables you to go straight into the
mixer of a recorder or PA system via the XLR Direct Output.
The Footswitch further expands the Landmark 300’s capabilities. In addition
to being able to remotely change channels, there is a MUTE switch which
allows you to silently tune your instrument, and a MIX function to simultane-
ously engage both channels, yielding 3 footswitchable sounds.
With the Landmark 300, you get a truckload of big amp sounds in a single
cost-effective package.

FRONT PANEL
The Landmark 300 is designed with active controls, which boost and cut, rather than
traditional passive controls which only cut. This effectively doubles many of the control’s capabilities, giving you a much larger range of adjustability and, ultimately,
more variety. It should be noted that you need not necessarily set everything at max
to achieve maximum results. As you experiment and become familiar with the interrelationship of the controls, you’ll easily be able to customize your own sounds.
Channel Selector Switch
Manually switches between channels when there’s no cable plugged into the rear
panel Footswitch jack. To remotely change channels, use any standard passive
footswitch or Tech 21’s Optional Footswitch (Model #BFSWL)
which will override the manual selector switch. (For more
information, refer to page 9.)
Gain
A 10dB gain boost to set up the pre-amp for different pickups.
For example, with lower output passive pickups, you can have
punchier sounds with Gain engaged. Conversely, with higher
output active pickups, you can have a cleaner sound with
Gain disengaged. Of course, you can also obtain over-the-top
distortion by using high output pickups with Gain engaged.
Input Jack
Faithful to the original designs of traditional tube amplifiers, this
1/4" Input is high impedance 1MΩ. The typically additional low sensitivity input, howev-
er, is not needed due to the Gain switch.
Bass and Treble
These active tone controls cut or boost ±12dB from unity gain at 12 o’clock. This
powerful EQ section effectively reduces the need for a fixed frequency mid control
and enables you to achieve an extensive variety of curves, including a “mid-cut” as
well as a “mid-boost.”
Adjusting Mid-Range Content: The mid-range level of Channel 1 is preset.
Boosting Bass and Treble gives you the equivalent of a “mid-cut” @ 750HZ where
the relative mid-range level is lower than the Bass and Treble frequency levels.
Cutting Bass and Treble is the equivalent of a “mid-boost” @ 750HZ where the relative mid-range level is higher than the Bass and Treble frequency levels. NOTE: The
overall output level will change in relation to the adjustments you make with the EQ
controls. You can compensate accordingly with the Level control.
Presence
Brings out the upper harmonic content and attack. For a smoother high end and for
clean settings, decrease to taste.
Blend
Allows you to blend the direct instrument signal with SansAmp Tube Amplifier
Emulation circuitry. In most cases, you will probably have this set at maximum (100%
SansAmp). For certain applications, however, such as an ultra-transparent sound or
for use with piezo pickup-equipped instruments, you may want to blend-in the direct
signal to achieve your desired sound. While the SansAmp Tube Amplifier Emulation
circuitry is bypassed when Blend is at minimum, the Bass, Treble and Level controls
remain active.
Level
Adjusts the volume level of Channel 1.
CHANNEL 1
Channel 1 offers an entire sound spectrum of the most coveted traditional bass amp
rigs, from vintage to modern styles. You can also obtain overdriven sounds without
having to invest in a complex system with multiple rack effects.
Drive
Adjusts the overall amount of gain and overdrive, similar to when the output section
of a tube amp is being pushed.

CHANNEL 2
Channel 2 offers a different approach to sculpting your sound. The parametric EQ
allows you to bring out particular frequencies to get maximum output and dynamics
with natural warmth and presence.
Drive
Adjusts the overall amount of gain and overdrive, similar to when the output section
of a tube amp is being pushed.
Bass and Treble
These active tone controls cut or boost ±12dB from unity gain at 12 o’clock.
Mid Shift and Mid
Sweepable, semi-parametric EQ controls range from 170 Hz to 3.0 kHz, ±16dB,
respectively. With the Mid Shift control, you can select the center frequency of the
mid-range control. With the Mid control, you can then cut or boost that frequency.
Level Selector Switch
Allows you to connect the Landmark 300 via the XLR Output to other equipment with
a variety of signal levels:
0dB position. Line-level output.
-10dB position. Pads down the line-level signal by 10dB.
Ground Lift
Connects or disconnects the ground circuits between the XLR Output of the amp and
the mixer. We recommend starting with the ground lifted. If necessary, connect the
ground by pushing the button in.
Pre-Amp Output
Effects Loop Send.
Power Amp Input
Effects Loop Return.
NOTE: If you set Mid Shift at 1kHz, Mid operates as a traditional mid-range control.
Level
Adjusts the volume level of Channel 2.
REAR PANEL
1/4” Speaker Outputs: Wired in parallel. Total load: 300W RMS @ 4Ω Min.
SansAmp™ XLR Direct Out
For recording, the SansAmp XLR output is like having a built-in direct box. You can
go direct to the board and get the same sound you hear coming out of the speakers
right onto tape or disc. The SansAmp circuitry not only captures the warm, rich, natural harmonics and sweet overdrive characteristics inherent to tube amplifiers, its
speaker emulation encompasses all aspects of multiply-miked tube amp rigs.
For live gigs, you can use this output direct into the PA system and you won’t need a
microphone in front of the amp. And you won’t have to subject the audience to a
sterile, muddy, or boomy bass tone.
Tuner Output
As long as the unit is plugged in, the tuner output provides a constant, unaffected
signal at all times, regardless of the position of the Level controls or the status of the
Mute button on the Optional Footswitch (see next page). This output can also be
used as a buffered out to send a transparent signal to other outboard gear.
USE WITH ACTIVE BASSES
Active electronics have higher output and typically generate more noise. To compensate, we recommend lowering the volume on your bass. Additionally, experiment with
using flat EQ settings and/or decreasing the Drive, Presence (in Channel 1) and
Treble controls.
INSTRUCTIONS FOR RACKMOUNTING
1. Unplug unit. Remove top cover. Install rack ears with provided hardware. Replace
top cover.
2. Considering its weight, we recommend mounting unit on bottom of rack case.
3. If there isn’t enough clearance at the bottom of the rack case, detach the rubber
feet simply by removing the screws.
4. If there’s too much clearance (with or without the rubber feet) and you have a gap,
provide additional support to the rear of the unit (such as larger feet, wooden shims,
etc.).

TRIPLE-FUNCTION FOOTSWITCH
(Model #BFSWL)
The Footswitch further expands the Landmark 300’s capabilities:
•CHANNEL remotely switches between
the two channels.
•MUTE allows you to silently tune your
guitar or change instruments.
•MIX engages both channels simultaneously, giving you three footswitchable
sound options.
Corresponding LED indicators let you know
the status of each switch. The Footswitch is powered via the cable, so batteries are
not required. And, unlike most amps which require a custom multi-pin connector, this
Footswitch is engineered to utilize any standard 1/4” instrument or speaker cable.
You can easily replace the cable should you lose it, or purchase different cable
lengths to suit your particular needs.
