Front Panel Controls - Laney Ironheat IRT30-112 User Manual

FRONT PANEL CONTROLS

1. INPUT: 1/4" mono jack socket. Connect your guitar here. Use only a good quality instrument cable.
2. PRE-BOOST SWITCH: Switches the input boost circuit on or off. The Pre-Boost circuit increases the input signal to the preamp
tubes, just like placing a boost pedal in your signal path. This drives the first preamp tube harder, resulting in more distortion. This works on
both channels.
3. PRE-BOOST CONTROL: Controls the level of boost applied to the guitar signal.
4. PRE-BOOST LED: This LED will illuminate when the Pre-Boost controls are activated.
5. LEAD GAIN: Controls the level of preamp gain on the Lead channel. Turning this control clockwise will add more distortion to your
guitar signal, ranging from light overdrive, to full on metal. Use this in conjunction with Lead Volume (8) to achieve the correct volume and
distortion level you require.
6. LEAD EQ CONTROLS: These are a traditional set of passive tone controls. Passive controls have the advantage of always sounding
musical at any of their settings, due to their unique interactive nature. This gives the player a more natural set of tools to shape their ideal
sound. Set these to midway (0) as a good starting point.
7. LEAD EQ PULL SWITCHES: Pulling on each of the EQ control knobs will shift the response of each control as follows:
Bass: Deep - This extends the low-end frequency response, resulting in a fuller, heavier sound for lower notes.
Mid: Shift - This lowers the frequency range of the mid control to give a tighter sound.
Treble: Shift - This broadens the Treble control frequency response, to give a rounder sound to higher notes, especially when used with
thin sounding pickups.
8. LEAD VOLUME: Controls the Lead channel volume. Experiment with different combinations of the Gain and Volume controls to
achieve different sounds. Reducing the Gain while increasing the Volume will result in a warm, open, overdriven sound as the power amp
is driven harder, while reducing the Volume and increasing the Gain will give a tighter, more modern sound with more distortion.
