Bogner Helios Eclipse - Channel Descriptions; Channel 1; Channel 2 & 3; Channel Select

BOGNER AMPLIFICATION 2
channel 1
This is a simple clean channel with just a volume control and a 3 position mode switch. Please note the
presence and bottom control on the back panel also affect the channel.
volume 1
Sets desired clean level, loudness.
mode switch
The middle position, “N” is the neutral setting, when toggled to the left, “B” will give you a brighter tone
and to the right, “S” a mid scooped sound, reminiscent of the 60’s blackface amplifiers.
channel 2 & 3
These are your two dirty channels; each one can be set via its own set of voicing switches for a variety of
medium to high gain overdriven tones. The channels are very similar, with channel 3 having a slight bass
cut for a more focused, tighter sound. It’s best to use ch3 for the highest gain settings.
gain 2 & 3
Here you individually control the amount of overdrive for each channel.
pre eq switch 2 & 3
These 3 position switches work in conjunction with their designated gain control, the middle is a neutral
position much like the dark channel on a plexi. Toggled to the left, you have the bright channel of a plexi,
and towards the right you have just a slightly brighter, more open sound. The higher the gain control is
set, the switch becomes less effective.
Hot / 80’s / Eclipse (+) voicing switch
Hot is considered the standard mode, which gives you the “hot” input, second channel of the original
Helios. Set to 80’s, the preamp gets more compression, which can also result in a volume drop,
depending on the overall level. If necessary adjust the volume to compensate. On channel 2, the “eclipse”
mode adds two more gain stages. For channel 3 you have the “eclipse +” mode, which adds the two gain
stages, with the addition of the 80’s mode compression circuit, this is the maximum gain you can achieve.
bass, middle and treble
These are your typical 3 band eq controls which are shared by both dirty channels and control the
frequency as labeled.
volume 2 & 3
Sets the individual loudness of each of the two overdrive channels.
channel select – back panel
This momentary push button switch lets you step through each channel. The default at power up is
channel 3, sequence from there on is 1, 2 and back to 3. The switch does not lose it’s function with the
foot-controller connected.
fx loop switch – back panel
This momentary push button switch lets you engage the fx loop. The switch does not lose it’s function
with the foot-controller connected.
