PULSETEK

PULSETEK is a three-band tube-amplified based on Pultec EQP-1A Program Equalizer.

It is sold individually and as part of PROCESSOR Bundle.

The first group adjusts the low frequencies and has three controls: boost, attenuation, and frequency select.

The second group adjusts the high frequencies and has three controls: boost, bandwidth, and frequency select.

The third group also adjusts the highs and has two controls: attenuation amount and attenuation frequency select.

When IN/OUT switch is set to OUT and ON/OFF switch is set to OFF, the signal is truly bypassed.

When IN/OUT switch is set to OUT and ON/OFF switch is set to ON, the signal passes through the amplifier section while the EQ is bypassed.

When IN/OUT switch is set to IN and ON/OFF switch is set to ON , the EQ is fully enabled.

The LOW FREQ switch determines the frequency of the low shelf portion of the equalizer. Four frequencies are available: 20, 30, 60, and 100 CPS.

LF BOOST knob determines the amount of low shelf gain to be applied to the frequency set by the CPS switch.

LF ATTEN knob determines the amount of low shelf cut to be applied to the frequency set by the CPS switch.

The HIGH FREQ switch determines the frequency of the high boost portion of the equalizer. Seven frequencies are available: 3, 4, 5, 8, 10, 12, and 16 KCS.

BANDWIDTH knob sets the proportion of frequencies surrounding the center frequency (determined by the KCS switch) to be affected by the high boost (this is a bandwidth control).

Lower values yield a narrower band and effect fewer frequencies.

HF BOOST knob controls sets the amount of gain for the high frequency portion of the equalizer.

HF ATTEN SEL determines the frequency of the high frequency attenuator. Three frequencies are available: 5, 10, and 20 KCS.

HF ATTEN determines the amount of high shelf cut to be applied to the frequency set by the Attenuation Selector switch.
