INTRODUCTION
Laney are the first amplifier brand to develop a REAL solution for players using a digital rig, providing
players with a stylish and imposing sound presence on stage.
As that market has grown, so too has the LFR’s reputation as the market leader in powered full range,
flat response (FRFR) guitar cabinets.
Following the huge success of our LFR-112 and LFR-212 powered cabinets, we’ve decided to offer up
the World’s first 4x12 dedicated FRFR guitar cabinet. The LFR-412
The LFR-412 offers you an incredible 2600 Watts, an industry leading and best in class powered
cabinet filled with output options. Ensuring the perfect partnership for whichever profiler you choose
to pair it with.
The LFR-412 features LA⋅IR (Laney Advance Impulse Response) technology that uses 56bit FIR filters
to provide stunning cabinet emulations. The LFR-412 ships with two IRs (Impulse Responses)
designed and used by the legendary guitarist Devin Townsend. The USB connectivity allows you to
load your own IRs, and the LA⋅IR LFR app allows for further adjustment. Housing the IR in the cabinet
frees up processing power within your digital rig, allowing for greater creativity and reliability. In
short; the LFR-412 does the heavy lifting.
The LFR-412 joins a range of Laney LFR powered cabinets that all feature tailor-made drivers,
designed and engineered by HH Acoustics to deliver power, precision and importantly a response
that gives you the feeling of a real guitar cabinet by your side. Why is this so? Well, with over 55 years
of amplification and cabinet design experience, we understand the thrill of feeling the air move to
you, the player, and your amp and cab. The LFR-412 offers an authentic response that feels familiar to
you in comparison to other options on the market.
These FRFR powered cabinets are raising the bar and redefining the standards that you expect from
your digital rig, all in an aesthetic package that guarantees to turn heads.

CONTROLS
1. VOLUME CONTROL
Volume attenuator for signal input to the LFR-412. Will mute at 0, and should be turned down if the
SIGNAL LED is lit red. Note that the aux input bypasses this volume control.
2. 3.5mm STEREO AUX INPUT SOCKET
Audio input socket intended for adding backing tracks to your playing. Bypasses the volume control
and any loaded IRs and EQ.
3. POWER AND SIGNAL LEDS
-Power LED will light green whenever the LFR-412 is plugged in and powered on.
-Signal LED will light green whenever the LFR-412 detects a signal present at the input socket.
This will turn red when a signal begins clipping at the preamp stage. Avoid this ever turning
red by turning down the volume or input level.
-Clip LED will light red when the internal amplifier is clipping. This is ok for a short while but
should be avoided over longer periods of time.

4. INPUT SOCKET
A balanced XLR / 6.3mm jack combi socket for your main audio signal input. Ideally use with a
balanced audio line, especially over long cable distances, to avoid noise interference. The LFR-412
features HDR technology to accommodate for a range of line input levels.
5. HF TRIM CONTROL
Tailor the cabinets high frequency response to your environment. A HF shelving filter set at 3kHz,
increase or decrease the high end of your signal quickly and easily.
6. LINK OUT W/ GROUND LIFT
Link out XLR socket that directly returns your input signal with no alteration whatsoever. Link to
another active cab to extend your system further. A ground lift switch is included to potentially reduce
any ground hum.
7. USB TYPE B SOCKET
Connect the provided USB-B to USB-A cable to a Windows or Mac PC to access the LFR-412’s IR
presets and cabinet EQ via the downloadable LA∙IR LFR app.
8. FRONT LED STRIP SWITCH
Turn on and off the LED downlight strip found on the front panel of the LFR-412 cabinet.

CONNECTING THE LFR-412
CONNECTING THE INPUTS
The Laney LFR-412 has two input sockets. An XLR / 6.3mm combi jack for your balanced guitar signal
input as well as a 3.5mm aux in to connect a backing track via a media player such as your mobile
phone. The aux in is post volume, user EQ and IR emulation so will not be affected by any tone
changes.
Thanks to the LFR-412’s high dynamic range, the input can accept hot and cold line level signals. Just
make sure the signal LED doesn’t turn red as this indicates the front end is clipping, which can cause
long term damage to the LFR-412.
CONNECTING THE DI OUT
The XLR DI-out provides a balanced line level output to connect to your PA, front of house or in ear
monitors. Unaffected by the volume or trim controls, the DI out has it’s own cabinet emulation and
user loaded EQ that applies separately to the cabinet EQ/IR’s.

Page 6
CONNECT TWO LFR-412
Two LFR-412’s can be connected together via the link out provided. An XLR socket direct from the
input, connect this to another LFR-412’s input socket. Note that the LFR-412 is stackable, allowing two
units to be placed on top of one another
CONNECT TO PC VIA USB
Connect to a Windows or Mac computer via the USB Type-B socket. A Type-B to Type-A cable is
provided as well as a Type-A to Type-C adapter depending on your computer’s USB ports.
From here you can download the LA⋅IR LFR app provided by Laney, to load your own IRs and tweak
the 8 band EQ for both the cabinet itself and the DI-out. Change these on the fly whilst playing to
hear your changes live and save these for later use when gigging or practicing.

SAFETY AND WARNINGS
In order to take full advantage of your new product and enjoy long and trouble-free performance, please read this owner's manual carefully,
and keep it in a safe place for future reference.
1) Unpacking: On unpacking your product please check carefully for any signs of damage that may have occurred whilst in transit from the
Laney factory to your dealer. In the unlikely event that there has been damage, please re-pack your unit in its original carton and consult
your dealer. We strongly advise you to keep your original transit carton, since in the unlikely event that your unit should develop a fault,
you will be able to return it to you dealer for rectification securely packed.
2) Amplifier Connection: In order to avoid damage, Generally it is advisable to establish and follow a pattern for turning on and off your
system. With all system parts connected, turn on source equipment, mixers, effects processors etc, BEFORE turning on your amplifier.
Many products have large transient surges at turn on and off which can cause damage to your speakers. By turning on your amplifier
LAST and making sure its level control is set to a minimum, any transients from other equipment should not reach your loud speakers.
Wait till all system parts have stabilised, usually a couple of seconds. Similarly when turning off your system always turn down the level
controls on your amplifier and then turn off its power before turning off other equipment.
3) Cables: Never use shielded or microphone cable for any speaker connections as this will not be substantial enough to handle the
amplifier load and could cause damage to your complete system. Use good quality shielded cables everywhere else.
4) Servicing: The user should not attempt to service these products. Refer all servicing to qualified service personnel.
5) Heed all warnings.

place objects containing liquids, such as vases, upon the apparatus.
21) Exposure to extremely high noise levels may cause a permanent hearing loss. Individuals vary considerably in
susceptibility to noise-induced hearing loss, but nearly everyone will lose some hearing if exposed to
sufficiently intense noise for a sufficient time. The U.S. Government’s Occupational Safety and Health
Administration (OSHA) has specified the following permissible noise level exposures: According to OSHA, any
exposure in excess of the above permissible limits could result in some hearing loss. Earplugs or protectors to
the ear canals or over the ears must be worn when operating this amplification system in order to prevent a permanent hearing loss, if
exposure is in excess of the limits as set forth above. To ensure against potentially dangerous exposure to high sound pressure levels, it
is recommended that all persons exposed to equipment capable of producing high sound pressure levels such as this amplification
system be protected by hearing protectors while this unit is in operation.
22) If your appliance features a tilting mechanism or a kickback style cabinet, please use this design feature with caution. Due to the ease
with which the amplifier can be moved between straight and tilted back positions, only use the amplifier on a level, stable surface. DO
NOT operate the amplifier on a desk, table, shelf or otherwise unsuitable non-stable platform.
