SHAPE Control Switch
The SHAPE control is a three position mini toggle switch located just below the top rotary knob on the
left side of the channel block. NOTE: Only SHAPE position 2 has effect on the 4110 Instrument Input as
the input transformer is only used for Mic & Line inputs.
Position OFF
This position selects the purest signal path, and is called the
Modern
position; Clean, clear, full
bandwidth that is distortion free.
Position 1
This position selects transformer loading, and is called the
Vintage
position. This setting changes the
loading on the mic/line input transformer to provide more of that “iron” sound popular in vintage
transformer-coupled preamps. This could be described as warmer and more present, with increased
sensitivity to the microphone’s impedance curve
;
A bit of harmonic coloration enhancing mid-
frequency tone and presence, or a more three dimensional character. Higher Gain settings will increase
these characteristics.
Position 2
This position is the same as position 1 with the addition of a soft limiting circuit. We call this position
Saturate
. This setting uses the same transformer loading as Position 1, but also adds additional
loading to the first stage preamp, which is perfect for smoothing out transients without clipping. When
using this position the input signal is naturally lowered. Experiment with higher Gain settings to
achieve greater “saturation” when using this mode.
Power Switch
The Main power switch is located on the far right side of the front panel. The up position applies power
to the preamp and lights a blue jewel lamp located above the switch.
Note: There is a short power cycle before the preamp is enabled. This delay is used to auto-calibrate
the preamp channels.
