Tractor Pronar 7150 will be appreciated by customers with high hardware requirements, it is excellent both in the field and in transport hard works. Mounted Deutz 6-cylinder turbocharged engine generates 176hp and is a guarantee of reliability and low operating costs. ZF gearbox gives the ability to select the appropriate gear ratio from the available 40 forward gears and 40 reverse gears. With powerful hydraulics with a maximum lifting capacity of 9500 kg and BOSCH EHR control it is ideal for field works with vide range of machines. Comfortable, muted, air-conditioned and safe cabin with additional passenger seat provides comfortable job.
The FM section of the NAD 7150 stereo receiver features the Schotz Variable Bandwidth PLL detector, whose announcement last year aroused much interest in audio circles. The detector of an FM tuner - the circuit that converts the varying frequency of the received FM signal to a varying-voltage audio signal-is one of the tuners more critical elements. Its bandwidth must be sufficient to accommodate the maximum frequency deviation of the broadcast signal (up to at least 75 kHz) without significant nonlinearity (which would result in distortion of the audio signals). However, the noise in the converted signal increases with the detectors bandwidth. The Schotz tuner circuit maintains the detectors bandwidth at the minimum value required by the reception conditions (signal strength, noise level, and amplitude modulation of the FM signal caused by multipath interference) in order to keep the noise level in the detected signal as low as possible.
This automatic bandwidth control is made possib le by the PLL (phase-locked loop) detector, whose internal oscillator locks onto the FM signal and tracks its instantaneous frequency. The low-frequency voltage that controls the PLL internal oscillator is an accurate analog of the demodulated audio program; modifying the characteristics of the PLLs filter with a composite signal-quality voltage (derived from circuits assessing signal strength, noise, and AM content) allows the effective detector bandwidth to be varied without increasing distortion.
