Connections and circuit (ideal SPICE model)

Inputs, outputs, power and control as its own documents name them (no RTO-144 sheet for it: pin numbers only where the page gives them). Run the generator, turn the gain, watch the VU.

Pinout & connections

Each contact as its own documents name it: 4 named (4 low confidence). An empty slot is a contact no page names. Hover a contact for its source; the table under the drawing lists them.

4-126 EQUALIZER FILTER AMPL IFIER The 4-126 equalizer filter amplifier printed circuit board utilized as an internal component certain WBS 460 series equalizer modules. The 4-126 comprises three independent state variable filter networks, designed operate the Low Frequency Mid Frequency and High Frequency bands the audio spectrum respectively Each these three filter sections functions pass shaped portion the audio spectrum thus genera ting correction signal be summed with the primary signal passing through the module.

conjunction with components external the 4-126 and part the main module, possible control the different parameters equalization indepen - dently each other such as frequency boost/cut and Each the three filter networks consists three operational ampli- fiers, one which operates the summing mode, with the two others functioning as integrators the summing amplifier, the outputs the two integrators are mixed with the original filter output signal, the compound output turn being fed back the integrating amplifiers.
