USER MANUAL
INTRODUCTION
In the 1700s the first Newcomen Steam Engines were designed and constructed
right here in the heart of England, in the midlands; a 100 years later the
skies were black with smog from burning furnaces, fuelling the legendary
industrial revolution. This was the beginning of the Black Country. As the
fire and brimstone that once scorched the sky began to fade, another type of
metal was born:
Heavy Metal; the beating twisted heart of the Black Country.
The IRONHEART FOUNDRY series is forged from fire and iron right at the heart
of the Black Country, the legendary furnaces rekindled to create a beast. We,
tone blacksmiths of the midlands, have created a monster.
We call it the IRF-DUALTOP, a 60-Watt twin channel amplifier in a compact head
format. It’s soul, from the IRONHEART that resides in the home of industrial
revolution, is designed in the UK by Laney’s dedicated design team.
Set to CLEAN, you get crystal clear cleans with sparkle and bite, while
setting to LEAD is all about the gain. It can deliver Earth shattering power,
from controlled gut punching tones at lower gains to untamed feral roars when
really turned up.
The 3 Band EQ section is the tonal offspring of the legendary IRONHEART valve
heads, capturing all their nuances and flexibility. This traditional passive
tone stack with complex interactivity never sounds bad. As well as the onboard
reverb – based on the BCC-SECRETPATH Spring line algorithm, the DUALTOP also
features a fully transformer isolated FX loop for a pure, noise free, high-
quality signal.
The XLR DI OUT is loaded with two high quality Laney customs IR’s and allows
you to connect directly to your DAW or FOH giving you totally flexibility for
noise free recording and streamlined cab-less stages. You never need to mic a
cabinet again.
An auxiliary input and emulated headphone output makes the DUALTOP ideal for
practising at home or on the move.
And then, if you dare, the last control. If you weren’t already maddened by
the insanity of the DUALTOP, the switchable BOOST is there to tip you over the
limit. Push your drive tones further and feel the very soul of the IRONHEART
scream out.
And yes, it may be small but it’s LOUD, you can choose just how loud this
monster is by the switchable WATTS control on the rear panel, Max, or <1W
ideal for the bedroom.

CONTROLS
FRONT PANEL 
-
INPUT SOCKET
Plug in the input jack from your guitar here, suits any standard 6.3mm mono jack. -
BOOST CONTROL
The boost control is an additional gain setting that acts as a boost pedal in front of your DUALTOP, driving your signal for more distortion. The LED above the control indicates when it is active and will work on both channels simultaneously. Ensure the switch is set to on when using a footswitch to control it. It’s especially pleasing when used to push the clean channel into slight breakup. -
CHANNEL 1 SETTINGS
Gain and volume settings to control your desired level for channel 1. The Gain Character Switch (GCS) can either be clean, asymmetrical or symmetrical, allowing for refined control over the distortion characteristics of the channel.
• CLEAN – Least amount of compression with this setting, more open tone with softer clipping.
• ASYM – Provides asymmetrical wave clipping adding more distortion whilst retaining some clarity and dynamics. Plenty of second harmonics
• SYM – Symmetrical wave clipping giving a more aggressive distortion for a high gain, compressed sound. -
CHANNEL SWITCH
Switch between the two channels. Ensure channel 2 is selected when using the footswitch to control channel. -
CHANNEL 2 SETTINGS
Gain and volume settings to control your desired level for channel 2. Channel 2 has more gain and a voicing switch which can be set to either neutral, bright or dark.
• NEUTRAL – No change to your signal
• BRIGHT – Extends the high frequencies and slightly dulls the low-end.
• DARK – Boosts the low-end frequencies adding some warmth to your tone, whilst reducing the power of the high frequencies. -
EQ SETTINGS
A 3-band passive EQ stack to further modify your sound. The three controls are linked so however you tweak them, the DUALTOP will always provide you with a musical tone.
• BASS – Adjusts the strength of the low-end response, gives a deeper sound when turned clockwise.
• MIDDLE – Adjusts the strength of the mid-range response, giving a fuller sound when turned up.
• TREBLE – Adjusts the strength of the top-end response, boosting the brighter higher notes. -
REVERB CONTROL
Our built-in studio quality spring line reverb effect based on our award- winning Secret Path pedal.
Reverb is evocative of space – a note contains pitch, but reverb contains place and fills out the sound.
Turn the knob clockwise to increase the strength of the effect.
BACK PANEL****
-
DI OUT
**** XLR output to connect to your audio interface or PA. Set the tone on the DUALTOP first then tweak your interface to get the sound you want.
• GROUND LINK – Disconnects the ground from pin 1 of the DI output ONLY. Useful to attempt to reduce ground loop hum when connected up to external devices.
• IR CAB SIMULATION – Choose between a 1×12 or 4×12 emulation added directly to your audio interface. Our own high-quality emulation will give you an authentic loudspeaker sound. -
HEADPHONE JACK
3.5mm jack to connect your headphones for silent practice. The headphone out socket follows whichever IR cabinet emulation setting is applied for the DI out so ensure this is set for the best sound. The loudspeaker socket is muted when headphones are used. -
AUX SOCKET
3.5mm jack to plug in any audio playing device to add a backing mix to your guitar track. This is added in after the FX loop. -
EFFECTS LOOP
6.3mm input and output jacks.
• FX SEND / LINE OUT (TRANSFORMER ISOLATED) – A multi-purpose output that can be used as a line level output or as an FX send to your other gear such as your pedal board or rack.
• FX RETURN – Connect the output for your FX loop gear back to the DUALTOP. All the signal is sent through your external gear when connected, so inserting a jack here will break the signal path. -
REMOTE SOCKET
6.3mm jack to plug in a footswitch to control the pre-boost function and active channel using a dual switch latching controller. The tip of the jack will control the boost, and the ring will toggle the active channel. Ensure the boost control is switched on and Channel 2 selected to allow them to be controlled. Recommended to use a Laney FS2-Mini (not included) -
LOUDSPEAKER OUTPUT
Connect to any 8ohm (minimum) or 16ohm passive speaker cabinet to unleash the power of the DUALTOP.
Do NOT connect to any other gear such as an effects unit or another amplifier input. -
POWER
Plug in the provided 100-240V~ power supply here. On/off switch to isolate the power. We suggest keeping the DUALTOP switched off when not in use. The front grille will light up to indicate the DUALTOP is powered on.
-
HOW TO CONNECT THE DUALTOP
INTO A PASSIVE CAB
Plug directly into a passive cabinet using the loudspeaker out socket. 
WITH AN FX LOOP
Connect your effects pedalboard to the FX loop of the DUALTOP. 
HEADPHONES AND AUX IN
FOR SILENT PRACTICE
The DUALTOP’s high quality headphone output can be connected for silent
practice. It is optimised for high impedance headphones, commonly the 33ohm or
above, though any can be used.
Add a backing track via the 3.5mm AUX connection. Plug in the aux/headphone
output of any media player, control its level on your device.
USING THE DI
OUT
The high quality, IR loaded, speaker emulated DI output can be connected to
any balanced line level input device such as a PA or audio interface to DAW.
Toggle off the cabinet emulation should you want to use your own in the
DAW.
You can
connect the DUALTOP to a passive cabinet as well as a PA system to use both
outputs simultaneously.

trouble-free performance, please read this owner’s manual carefully,
and keep it in a safe place for future reference.
-
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.
-
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. -
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.

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.
-
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.
