Laney IronHeart IRT15H Operating Instructions Manual page 9

With molten metal flowing through its circuits, IRONHEART continues the legacy passed on by previous Laney amps such
as KLIPP and AOR, and hits you hard between the eyes like a power hammer from hell.
As a member of the IRONHEART family, the IRT15H has the same ferocious DNA beneath its hard metal chassis, emitting
the familiar dark red glow that warns of the power ready to be unleashed.
The IRT15H is a single channel 15W valve amplifier which features
High and Low power modes, allowing the output to be switched
right down to less than 1 watt output power. It also has the same
foot switchable Pre-Boost function from its bigger brothers, which
works just like kicking in a gain pedal in front of your amp.
Combine your IRONHEART head with an IRT412 or IRT212
speaker cabinet for the ultimate tonal experience.
Forged deep within the Black Country - the metal beating industrial
heartland of the UK - where the sound of metal guitar was born, comes
the IRONHEART.
