Chandler Germanium Tone Control EQ - Pair #000911/12 (Used)

The Chandler Germanium Tone Control EQ uses active and passive EQ circuits in combination with the Germanium amplifier developed for the Germanium Pre and incorporates the versatile Feedback and Drive controls as well.

All bands use inductors for the fattest smoothest tone possible.  The passive low frequency section is selectable between "Pultec/Lang" interactive curves and more standard low frequency with pass filter for maximum flexibility while the Treble and Presence bands are active and designed to sound like your favorite British eq’s from yesteryear.  The Tone Control continues the Germanium tradition of undeniable sound with maximum flexibility at a reasonable price.  Fans of the Pre are sure to love it!

Chandler PSU-1 is needed to power unit.

GAIN/GERMANIUM DRIVE - A gain switch in 3 dB steps, this is your standard input level type control. The actual amount of overall gain, however, is affected by feedback control. With gain at 0 and feedback at zero, overall gain is -30 dB. Moving the feedback to 10 overall gain becomes -8 dB with all the tonal changes described under the feedback control.

Available gain of the unit is -30 db with Gain and Feebdack at 0 to +25 dB with the Germanium Drive and Feedback at full. Using different combinations of feedback and input gain is essential if you want to take advantage of all the available tones from the Germanium preamp.

FEEDBACK - The Feedback control is essential to the sound and function of this EQ’s amplifier. Audio amplifiers incorporate some amount of negative feedback which is where the output signal of the amplifier is fed back to its input. This affects the sound and function of the amplifier in many ways.

THD, frequency response, gain and amplifier stabilization change considerably with varying feedback. Please refer to the section about unity gain for the tone variations available by using Gain and Feedback combinations.

BYPASS - You may bypass the passive Thick or low frequency section and the active Presence and Treble sections of the Tone Control separately for maximum flexibility. To bypass both at the same time, simply place the passive and active pushbuttons in the out position.

INTERACTIVE/INDEPENDENT - As one of the important controls for flexibility, this switch affects how the Thick boost and cut interact to create variations of the EQ curves. In INTERACTIVE mode the boost and cut work in a similar manner to Pultec and Lang EQs whereby boosting and cutting at the same time makes the curves "interact" to create cool variations.

For example, by boosting at 70 Hz and cutting at 240 Hz you get a drop near 350 Hz and a peak at 70 Hz. Boosting at 70 Hz and cutting at 320 Hz will give you a drop at 450 Hz and a peak at 70 Hz. Please note that different frequency choices will create different boost/cut curves. For example, when cutting at 320hz you will get a lower cut point by lowering the boost point.

To illustrate the effect of INTERACTIVE further, if you were to do similar settings on a standard console EQ you would simply get the cut at 240 Hz or 320 Hz because the cut would take precedence over the boost. INTERACTIVE allows you to use both together to create normally unattainable equalizer responses.
