IMPORTANT SAFETY INSTRUCTIONS
WARNING: When using electric products, basic cautions should always be followed, including the following.
1. Read all safety and operating instructions before using this product
2. The product should be powered by a three pin `grounded (or earthed) plug connected to a power socket with a grounded earth outlet.
3. All safety and operating instructions should be retained for future reference
4. Obey all cautions in the Operating instructions and on the back of the unit
5. All operating instructions should be followed
6. This product should not be used near water, i.e. a bathtub, sink, swimming pool, wet basement, etc.
7. This product should be located so that its position does not interfere with its proper ventilation. It should not be placed flat against a wall or placed in a
built up enclosure that will impede the flow of cooling air.
8. This product should not be placed near a source of heat such as stove, radiator, or another heat producing amplifier.
9. Connect only to a power supply of the type marked on the unit adjacent to the power supply cord.
10.Never break off the ground pin on a power supply cord.
11.Power supply cords should always be handled carefully. Never walk or place equipment on power supply cords. Periodically check cords for cuts or signs of
stress, especially at the plug and the point where the chord exits the unit.
12.The power supply cord should be unplugged when the unit is to be unused for long periods of time.
13.If this product is to be mounted in an equipment rack, rear support should be provided.
14.The user should allow easy access to any mains plug, mains coupler and mains switch used in conjunction with this unit thus making it readily operable.
15.Metal parts can be cleaned with a damp cloth. The vinyl covering used on some units can be cleaned with a damp cloth or ammonia based household
cleaner if necessary. Disconnect the unit from the power supply before cleaning.
16.Care should be taken so that objects do not fall and liquids are not spilled into the unit through any ventilation holes or openings. On no account place
drinks on the unit.
17.A qualified service technician should check the unit if:
18.The user should not attempt to service the equipment. All service work is done by a qualified service
technician.
19. 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 exposure. (See oposite).
According to OSHA, any exposure in excess of the permissible limits could result in some hearing loss. Ear
plugs or protectors in 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 exceeds the limits 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.
!The power cord has been damaged
!Anything has fallen or spilled into the unit
!The unit does not appear to operate correctly

BEFORE SWITCHING ON
After unpacking your amplifier check that it is factory fitted with a
three pin 'grounded' (or earthed) plug. Before plugging into the
power supply ensure you are connecting to a grounded earth
outlet.
If you should wish to change the factory fitted plug yourself, ensure
that the wiring convention applicable to the country where the
amplifier is to be used is strictly conformed to. As an example in the
United Kingdom the cable colour code for connections are as
follows.
NOTE
This manual has been written for easy access of information. The
front and rear panels are graphically illustrated, with each control
and feature numbered. For a description of the function of each
control feature, simply check the number with the explanations
adjacent to each panel.
Your Laney amplifier has undergone a thorough two stage, pre-
delivery inspection, involving actual play testing.
When you first receive your Laney guitar amplifier, follow these
simple procedures:
(i) Ensure that the amplifier is the correct voltage for the country
it is to be used in.
(ii) Connect your instrument with a high quality shielded
instrument cable. You have probably spent considerable money on
your amplifier and guitar - don’t use poor quality cable it won’t do
your gear justice.
Please retain your original carton and packaging so in the unlikely
event that some time in the future your amplifier should require
servicing you will be able to return it to your dealer securely
packed.
Care of your Laney amplifier will prolong it's life.....and yours!

Dear Player,
Thank you very much for purchasing your new Laney product and becoming part of the worldwide Laney family. Each
and every Laney unit is designed and built with the utmost attention to care and detail, so I trust yours will give you
many years of enjoyment.
Laney products have a heritage which stretches back to 1967 when I first began building valve amplifiers in my parent’s
garage.
Since then we have moved on from strength to strength developing an extensive range of guitar, bass, public address
and keyboard amplification products along with a list of Laney endorsees that includes some of the world’s most famous
and respected musicians.
At the same time we believe we have not lost sight of the reason Laney was founded in the first place - a dedication to
building great sounding amplification for working musicians.
Warm Regards,
Lyndon Laney CEO

INTRODUCTION
The LC50-112’s 50W Class A/B output stage oozes classic, warm tube tones: The harder you drive it, the better it sounds.
Plus with enough gain for contemporary tones, it also has a mean, spiteful side to it as well – making it ideal for any style of
playing. Perfect for studio and practice use, but also equally at home or on stage by itself or plugged into a Laney extension
cabinet, the sound will blow you away.
Your LC50-112 should give you years of trouble-free amplification, however please take time to read this manual and familiarise
yourself with the controls as it will allow you to get the best from your amplifier. We hope you enjoy using your LC50-112 as
much as we enjoyed designing and making it.
Best wishes from all at Laney

CHANNEL Switch in to enable the 'Drive' channel. (This switch must be in the disengaged position in order for
the drive to be switched remotely via a foot switch.)
This led will illuminate when the Drive channel is activated with the Drive switch (8) or an optional Laney FS2
remote footswitch.
Sets the level of tube preamplifier drive or how dirty your sound is. This control should be used in conjunction with
the Drive Volume (12) Setting low levels of gain with high levels of volume will give a clean preamplifier sound with tube
output stage overdrive. Setting a medium drive level and medium Drive Volume will give a nice crisp bluesy tone, again with
the ability to drive the output stage at higher Drive Volume settings. Setting a high level on the Drive control and a low
setting on the Drive Volume will give you a punchy hard rock tone, with the ability to again drive the output tubes at higher
Drive volume settings. Having set the Drive and Drive Volume controls to your desired sound try backing off your guitar
volume and tone controls for lots of other cool sounds. Good tube amplifiers have the unique ability to produce a wide
range of sounds by using only your guitar controls, playing weight and style.
MODERN: The modern switch applies a degree of compression & bass lift to the signal, providing massive smooth sustain.
BASS, MIDDLE, TREBLE: These are a traditional set of passive tone controls for the Drive channel and work in the
same way as those for the clean channel.
Sets how loud the 'Drive' channel is
-
The tone control works in a similar fashion to the Tone control you probably have on your guitar except that it
uniquely works at the other end of the amplification chain. This has the ability to not only control the overall top end
response but also reduce upper end harmonics on the output stage and preamplifier overdrive sounds. This will give you
bright cutting sounds at high settings and smooth rounded sounds at lower settings. (Midway (5) is a good starting point)
REVERB: Controls how loud the built in reverb sounds. The reverb in the LC50-112 is a legendary Sound Enhancements
aka ‘Accutronics reverb’ - the only choice for that authentic reverb sound
(Always switch off and disconnect the power
cord when not in use)
STANDBY: Disconnects the main HT voltage from the tubes but keeps the tubes warm so that they are ready to go
instantly. Switch off for short breaks when you don’t want to wait for the tubes to warm up again.
POWER: Main power switch for the unit. Tube amplifiers take between 30 seconds and 2minutes to warm up and be ready
to play after switching on, this is normal. Use in conjunction with the standby switch.

DRIVE VOL: . It is useful to experiment with drive levels and drive volumes. If you
want a very open, warm and semi overdriven sound try reducing the amount of drive and increasing the drive volume. This
reduces pre amp gain but pushes the power amp section and makes it work harder giving you a very desirable level of power
amp distortion which is a very pleasing “retro” style sound.

‘Hi’ stands for high gain. This input is designed for the connection of low output level guitars making it well
suited for guitars with single coiled or low gain humbucker type pickups. Use of high gain pickups in this input may drive the
preamp too hard causing a "mushy" sound. Only use good quality guitar cable.
Lo’ stands for low gain. This input is attenuated down approximately 50% from the Hi input and is designed for
high output level guitars. It is useful in obtaining output that is "tight" not "mushy" from high gain humbucker type pickups
Only use good quality guitar cable.
GAIN Sets the level of tube preamplifier Gain or how dirty your sound is. This control should be used in conjunction with
the Volume control, setting low levels of gain with high levels of volume will give a clean preamplifier sound with tube output
stage overdrive. Setting a medium gain level and medium volume will give a nice crisp bluesy tone, again with the ability to
drive the output stage at higher volume settings. Setting a high level on the gain control and a low setting on the volume will
give you a punchy hard rock tone, with the ability to again drive the output tubes at higher volume settings. Having set the

sounds. Good tube amplifiers have the unique ability to produce a wide range of sounds by using only your guitar controls,

Adds brightness and life to the treble frequencies of your guitar when on the clean channel. The switch has more
effect at low Clean Volume control settings. Use in conjunction with the Treble and Tone controls for optimum performance.
BASS, MIDDLE, TREBLE: These are a traditional set of passive tone controls for the clean channel. Passive controls have
the advantage of always sounding musical at any of their settings mainly due to their unique interactive nature. This gives
players a more natural set of tools to create their ideal sound. (Try them all set at midway (5) as a good starting point).
VOLUME Sets how loud the clean channel is. Try cranking it up a little to drive the power tubes harder for that real retro
sound and feel that only a quality tube amplifier can deliver. Now use your guitar volume to control the amount of distortion.

playing weight and style.
Adds brightness and life to the treble frequencies of your guitar when on the clean channel. The switch has more
effect at low Clean Volume control settings. Use in conjunction with the Treble and Tone controls for optimum performance.
BASS, MIDDLE, TREBLE: These are a traditional set of passive tone controls for the clean channel. Passive controls have
the advantage of always sounding musical at any of their settings mainly due to their unique interactive nature. This gives
players a more natural set of tools to create their ideal sound. (Try them all set at midway (5) as a good starting point).
VOLUME Sets how loud the clean channel is. Try cranking it up a little to drive the power tubes harder for that real retro
sound and feel that only a quality tube amplifier can deliver. Now use your guitar volume to control the amount of distortion.

POWER INLET SOCKET: Connect to your power source. Make sure the specified voltage is correct for your country!
POWER FUSE: This drawer contains the main safety fuse for the unit. The fuse protects the AC power to the amplifier.
USE ONLY THE CORRECT SIZE AND RATING OF FUSE AS SPECIFIED ON THE PANEL. If a fuse blows or fails and a
replacement of the same size and rating is installed and it in turn blows, the amplifier has suffered a malfunction internally and
needs immediate service from a qualified technician. DO NOT TRY USING A FUSE OF HIGHER RATING. Using a fuse that
is too large in current rating may cause serious, irreparable damage to the amplifier and presents a serious fire hazard. The
mains fuse ratings are detailed in the specs section at the rear of this manual
HT FUSE: This fuse protects the DC power to the tubes within the amplifier. USE ONLY THE CORRECT SIZE AND
RATING FUSE AS SPECIFIED ON THE PANEL. If a fuse blows or fails and a replacement of the same size and rating is
installed and it in turn blows, the amplifier has suffered a malfunction, at this point check the output tubes and replace faulty
ones if required. Should tubes not be the problem the amplifier should be checked out by a qualified technician. Do not try
using a fuse of greater value. Using a fuse that is too large in current rating may cause serious, irreparable damage to the
amplifier. Fuses are designed to protect, do not take chances.
SERIAL NO: Displays the model and serial number of the unit.
EFFECTS LOOP: SEND/LINE OUT: Connect the input of your external effect to this socket. All of the signal leaves the
amplifier via the `Send’ socket to be processed and comes back from the effects via the `Return` socket. This socket can also
be used to control another L 5 -112 amplifier connected to this socket via its own return socket. Some Effects are better
suited to being between the guitar and amplifer input - these are foot pedal types / distortion / wah wah pedals etc. Rack
mount effects will work better in the FX loop on the amplifer rear. Stomp boxes are normally designed for small signals such
as a guitar output whereas rack mount FX are designed for the higher signal level obtained from an FX send. This socket can
also be used as a Line Level Out.
C 0
BY-PASS/LEVEL SWITCH: This switch allows the effects loop to be by-passed if not in use, it also gives you the option
of running the FX loop at 0dB (750mV) or at -10dB (250mV) to suit your processor.
EFFECTS LOOP: RETURN: Connect the output from your external effects to this socket. The effects loop allows you to
connect external effects such as tremolo’s, chorus and delays to your amplifier. All of the signal leaves the amplifier via the
`Send’ socket and comes back from the effects via the `Return` socket. Use the output level control on your FX to control
how loud the FX return signal sounds. This is an insert type control, therefore you need to set the Dry/ Wet mix in your FX
processor.
FOOTSWITCH SOCKET: Provided for the connection of a Laney FS2 footswitch (optional) .This allows you to remotely
switch between the clean/drive channel and & switch the built in reverb On/Off.
INTERNAL CABINET: y a ¼” (6.3mm)
the impedance selector 6 L 5 -112
L 5 -112
L 5 -112
EXTENSION CABINET: Use to connect an 8-16 ohm extension cabinet. Please note mismatched impedance will reduce
the amplifiers performance and in some cases may cause damage to your amplifier. Try the L 5 -112 into a Laney extension
cabinet - you will be amazed what this baby cranks out.
The internal loudspeaker is connected b jack to this socket. With no extension
cabinet connected ensure that switch ( ) is set to 8 ohms. In use your C 0 should always have
a speaker connected otherwise you risk damaging the C 0 ’s output transformer.
IMPEDANCE SELECTOR SWITCH: This optimises the C 0 ’s output for 4 or 8-16 ohm loads. When using with
the ‘on board’ speaker set to it 8 ohms. If using an 8-16 ohm extension cabinet at the same time as the onboard speaker, set
the switch to 4 ohms. If you set it wrong it will reduce the life of your output tubes and won’t sound as good.

Amplifier connection In order to avoid damage, it is advisable to establish and follow a pattern for turning on and off your
equipment. With all system parts connected, effects processors etc. BEFORE turning on your guitar amplifier. Many products have
large transient surges at turn on and off which can cause damage to your speakers. By turning on your guitar amplifier LAST and
making sure its Volume controls are set to minimum any transients from other equipment will not reach your loudspeakers. Wait until
• Tube amplifiers; generally sound much warmer/sweeter than solid state transistor amplifiers but they also need a little more
respect due to the fragile glass tubes themselves. The LC50-112 uses top quality tubes, which should give you years of trouble free
service, however like all tube amps; it is important to treat it with a certain amount of care.
• Tubes are fragile glass components; they can easily be damaged if thrown in and out of vehicles,
• Make sure the impedance; of your cabinets matches the setting on your amplifier. Improper impedance matching will result in
reduced output power output and compromised sound at best and amplifier failure/premature tube failure at worst.
• Allow the amplifier; to warm up to room temperature before switching it on, The sudden thermal shock generated can crack
the cold glass tube housing plus any moisture is bad news around high voltage electronics.
• Allow the amplifier; to cool down after playing before moving. Hot tubes are more susceptible to damage than cool ones.Use
good quality loudspeaker leads, cheap leads are often not up to the job of handling the large requirements for loudspeakers and can
often short out.
• don't like running into a circuit. A tubes life expectancy is based upon a number of factors which include
operating temperature, how hard and how often it is played, vibration due to travel etc. Tubes should be changed in your amplifier if
you notice any change in your amplifiers performance etc. They need not be changed at any regular interval.
• Typical problems; with preamp tubes can be a crackly noise, hiss, hum and microphony. The preamp tubes can safely be changed
with no action required if they fail or reduce in performance. Typical output tube problems can be blown HT fuse; sound lacking in
punch, sound lacks extreme highs or lows and low level hum. The Output tubes can be replaced singularly if you replace them with the
exact same type AND grade as factory fitted otherwise they should be replaced as a quad set. See the diagram following to see how
to check the tube grade fitted. Exact replacement preamp tubes and matched sets of output tubes are available from Laney via your
dealer.
• To change a tube; switch off the unit and unplug from the mains supply. Wait for the tubes to cool down. Lay amplifier down on
its front face and remove the protective grille held in place with four screws. You should now be able to access the underside of the
amplifier chassis. Preamp tubes can then be gently pulled out. Take care
when pushing the new tube in to make sure the pins are all aligned properly.
Tube amplifiers; open
have a spring retainer which must be pulled away, the tube
The output tubes have a spring retainer fitted to the tube
socket which grips the base of the tube. The tube must be released from this by pushing the retaining clips down with one hand, whilst
gently rocking and pulling the tube from its socket with the other. Take care when pushing the replacement tube past the retaining
clips to ensure that the rib on the base of the tube is aligned in its locating slot in the socket.
