SONY TA-4300F 3-Channel Crossover Dividing Stereo Pre Amplifier Vintage Audio Domo Arigato! Welcome, Thank you for your visit. Description Operation confirmed. The appearance has small scratches, dullness, dirt, etc. due to normal use. For other appearances, please refer to the photo. *The power supply voltage is AC 100V specification in Japan.Please be careful about the voltage in your country.If the power supply voltage is different, you will need a voltage transformer. Overview A dividing preamplifier designed to convert amplifiers such as the TA-3200F, TA-1120F, and TA-3060 into multi-channel systems. It makes extensive use of low-noise, low-distortion audio FETs newly developed by Sony for HiFi applications.The use of these FETs in the signal path results in less distortion and noise than conventional channel dividers. There are six crossover frequencies: 150, 250, 400, 600, 800, and 1000 Hz for the low-mid range, and 1.5, 2.5, 3.5, 4.5, 6, and 8 kHz for the mid-high range.The cutoff characteristic is 18 dB/oct. The low end of the midrange remains unchanged, and the cutoff frequency can be changed in four steps for the low-frequency channel alone. This allows fine-tuning of the sound connection between the low-frequency and mid-frequency speakers, which is especially important.This shift works for each of the crossover frequencies in any position. A low-frequency compensation knob is provided for boosting the low-frequency range.There are five compensation characteristics: 0, 3, 6, 12, and 18 dB at 20 Hz. The turnover frequency is set at 150 Hz and 12 dB/oct by various experiments. A center channel output terminal for 3D is provided.
