PROGRAM EQUALIZER tube based equalization done right

PE 1C The TUBE-TECH PE 1C is a passive tube based program equalizer designed to meet the exacting standards of even the most demanding studio engineers.

Product Description The TUBE-TECH PE 1C Program Equalizer contains a low frequency boost and attenuation section (shelving), and a high frequency boost section (peaking). The high frequency section has variable bandwidth as well as attenuation (shelving).

The filter section is of the the passive type followed by a tube based push-pull amplifier to restore the gain. Input and output are balanced as well as fully floating. Input and output transformers come with a static screen between the primary and secondary wirings.

Product Features

• Passive equalizer • Tube based push-pull amplifier • 4 low frequency boosts: 20, 30, 60 and 100 Hz

TUBE-TECH PE 1C program equalizer DESCRIPTION

The TUBE-TECH program equalizer PE 1C contains a passive filter and a tube (valve) based amplifier to restore the loss from the filter. The filter has a low frequency boost/attenuate section with 4 selective frequencies, a high frequency boost section with a variable bandwidth and 10 selective frequencies and a high frequency attenuation section with 3 selective frequencies. The filter is placed directly after the input transformer therefore eliminating noise from the amplifier when boosting either low- or high frequencies. The amplifier consists of two tubes (valves) in push-pull configuration (one ECC 83 as the pre-amp and phase splitter, and one ECC 82 as the output stage), and an output transformer. Both input and output are balanced and fully floating. The in/out key switches the filter in and out without clicks and changes in level, while the amplifier remain in the signal path. The power supply for the pre-amp and phase splitter are stabilized and the heaters of both tubes (valves) are fed with a stabilized DC voltage. The whole amplifier (including input and output transformer) and the power supplies are placed on one PC-board.

CONTROLS:

LOW FREQUENCY SECTION: The low frequency section consists of a BOOST and ATTENuate control and a LOW FREQUENCY switch located just below.

BOOST:

The BOOST control is continuously variable from 0 dB to +14 dB. It is of the shelving type.

ATTEN:

The ATTENuate control is continuously variable from 0 dB to -18 dB. It is of the shelving type.

LOW FREQUENCY: The LOW FREQUENCY switch determines at which frequency the maximum boosting and attenuation is obtained. There is a choice of 4 frequencies: 20, 30, 60 and 100 Hz.

HIGH FREQUENCY SECTION: The high frequency section consists of two separate circuits: 1. A high frequency boost section, which contains a BOOST control, a BANDWIDTH control and a HIGH FREQUENCY switch. 2. A high frequency attenuate section, which consists of a ATTENuate control and a ATTEN SELECT switch.

BOOST SECTION:

BANDWIDTH: The BANDWIDTH control is continuously variable from SHARP to BROAD. It controls the width of the high frequency boost curve.

BOOST:

The BOOST control is continuously variable and is of the bell type. The gain is depending of the setting of the bandwidth control. When the bandwidth is in the sharp position the gain is from 0 dB to +18dB. When the bandwidth is in the broad position the gain is from 0 dB to +10dB.

HIGH FREQUENCY: The HIGH FREQUENCY switch determines at which frequency the maximum boosting is obtained. There is a choice of 10 frequencies: 1, 1.5, 2, 3, 4, 5, 8, 10, 12 and 16kHz.

ATTENUATE SECTION:

ATTEN:

The ATTENuate control is continuously variable from 0 dB to -18 dB. It is of the shelving type.

ATTEN SEL:

The ATTEN SELect switch determines at which frequency the maximum attenuation is obtained. There is a choice of 3 frequencies: 5, 10 and 20 kHz.

IN/OUT:

This lever switch switches the filter in and out of the signal path. The amplifier remains in the circuit.
