The input circuit for mono or stereo signals (with frequencies lower than 53kHz) is unbalanced with an input impedance of 0. LOW FREQUENCY CIRCUIT (EL08/1-2 boards) MF and ST versions The “low frequency input filter” module is composed of two overlaying boards housed in the rear of the rack in direct contact with the input connectors. DC voltage of -12V. Input levels are normally calibrated for 0dBm. while output which is present also as a VDU on the front panel is set at a fixed level of 6 dBm (1550mVrms). +28V DC Voltages The input is composed of 3 x Rectifier Bridges (RD1.

RD1 bridge.HPT40 MODULES DESCRIPTION POWER SUPPLY (ALSW40 module) This module supplies -12.5V. There is provision to set the various levels of both the single signals and the composite signal. it is possible to insert pre-emphasis and adjust the level of the overmodulation indicator.5V. +12. powered by an 28Vrms secondary of the toroidal transformer. through an appropiate regulation circuit. which allow regulation of the total gain. powered by a 16Vrms secondary. supplies DC voltage of +5V through the 7805 regulator. On the module there is also a circuit to measure the level of the sound signal.2. ELC40 17 . to 40W RF module. stereo.

The three unbalanced inputs for SCA signals accept input frequencies up to 200kHz. powered by an 8V rms secondary of the toroidal transformer. RD3 bridge. DC voltage of +28V-5A. with a level of +6dB for maximum Deviation. LOW FREQUENCY CIRCUIT (BFI board) M version The purpose of this module is to apply sound signals (mono. in addition. at 19kHz attenuation typically exceeds 50dB. After the first two stages. that. From this voltage.1dB. On the right. there is the pre-emphasis circuit by means of which variable time constants can be obtained between 40 and 80 microseconds (factory set at 50µS for CCIR. for reading on the multimeter located on the front panel. It has the task of controlling the various input signals (MPX.3). RD2 bridge. the U5 regulator supplies DC Voltage of +24V. eliminates the harmonics and eventual switching glitches caused by the audio signal clip. If the audio input signal is lower than the threeshold set. its response in amplitude and phase within the 53 KHz is excellent and therefore does not prejudice separation of the left and right channels of the stereophonic signal. this switching function is in relation with the audio level of the audio signal applied to the left and right channels. The intervention threeshold is adjusted by the R1 trimmer. while R57 adj its phase. ELC40 18 . after the integrated circuit U3 has been divided by U3 with its eight “shifted” outputs. the audio input signal is delivered directly to the audio output without any level and phase variation. even if the audio input level will double. is composed of a LIM circuit and it intends to limit the frequency deviation at +/-75KHz.The analog signals are switched by means of very low distortion and noise analog switches. The following low pass filter located at the EL081 board. it makes it possible to build the pilot tone frequency by approximation by means of a weighted sum. The R12 trimmer polarizes the analog switches and adjusts itself for minimum distortion of the decoded signal. which automatically sets the positive and negative values. The amplitude of the 19 KHz pilot tone is adj by R59. If the audio input signal exceeds positively or negatively the threesholds set. STEREO GENERATOR CIRCUIT (EL09 module) S version The audio signals coming from the input boards containing the 15KHz audio filters enter the MPX module (EL09 board) at J1 and J2 respectively. The R8 trimmer is used to balance the two commutation signals and should be adjusted to have maximum suppression of the 38KHz. This circuit delivers three properly switched signals to an amplifier. Since this Bessel filter’s cut-off frequency is over 300KHz. This makes it possible to have the commutation spurious emissions of the multiplex signal at a much greater frequency than the maximum frequency of the stereophonic signal and so they can easily be eliminated with a Bessel filter of the fifth order on the input boards. but the level of these oscillations doesn’t increase the deviation more than 1dB. STEREO LIMITER CIRCUIT (SLIM board) MF/LM and S/LM versions The SLIM board. a negative and positive voltage exactly equal to the threeshold value is then delivered to the audio output. such circuit is inserted between the left and right audio inputs and the relevant 15KHz low pass filters. They are then taken to the level of 2Vrms by U12 and U13 then enter the analog switches that work at a frequency of 608KHz. The 19KHz subcarrier is also generated by the 9728KHz crystal. located between EL081 and EL082 boards. This commutation frequency is a multiple of the pilot tone frequency (19KHz) and it is derived from a crystal oscillator (U3) operating at 9728KHz and from two shift-registers (U5). The precision modulation intensity detector is peak-to-peak and gives error-free response up to and over 100kHz. The group delay of the low pass filter may originate small oscillations on the clip. This function is useful in order to verify the frequency deviation value with “musical” signal.E. peak and semi-peak modulation. whereas the R17 ELC40 19 . the R70 trimmer adj the level of the output signal.

All the stages are in AB Class to ensure an adequate stability even with very low output powers. Infact the choice of use of the “BARGRAF” is necessary in order to have a good response with “music” signal. The trimmer R10 fixes the polarization of the second stage.The multiplex signal is summed with the pilot tone frequency with a suitable weight through the operational amplifiers U15 and U16.

This control is effected by pre-setting 20 dip-switches of the total desired power (2 40W) and. fixed on the internal side of the front panel.2dB.fixes that of the last one. besides showing the direct and reflected power. a rejection of the harmonics better than 70 dB. we find the Directional Coupler module (strip-line configuration) which. The Directional Coupler Insertion Loss is lower than 0. taking into consideration the thermic drift of the detector diodes. provided it is supplied with the suitable directional coupler. is followed by a Low Pass Filter of 9th order which ensures. The amplifier which supplies more than 60W output power on the whole range. of the directed and reflected power. By means of two optoinsulated inputs. The detected voltages. After the Low Pass Filter. has two functions: the acquisition (by means of 5 decimal dip-switches) of the frequency.
