CJMCU-472 TS472低雑音マイクプリアンプモジュールエレクトレットマイク専用ボード
Petit preampli avec gain ajustable et mode standby.
Very good for guitar pre amp.
ok bonne réception
I did some measurements: - Supply voltage 5.5 V - setting '40' connected - Max Uout = 4 Vtt (not bad at all) - frequency range about 50 Hz .. 20 kHz For simplicity I connected the IN- and OUT- to GND, and used IN+ as (unbalanced) input and OUT+ as output. Note: amplification can be pre-set to 10x, 20x, 30x 40x. The 'dB' in 'GAIN (dB)' as shown on the board should be just 'X'.
segnale in uscita abbastanza pulito
professionale. nessun rumore. ingresso bilanciato uscita bilanciata. guadagno in db notevole. quasi totale assenza di rumore di fondo. Soddisfatto!
Works as advertised.
Very good.
OK
