2-4. Input Level Range Confirmation and Level Setting
Measurement Equipment Audio signal generator Audio distortion meter, BKPF-202 Preparation 1. Connect each equipment. (Refer to Fig.1 in Section 2-1-2.) 2. Turn on the power of the main unit (PFV-D20/D50/D100A/D200A/D300) and warm up for ten minutes. Procedures 1. Provide an analog audio signal of 1 kHz, +4 dBm from an audio signal generator to the ANALOG IN AUDIO 1 connector of BKPF-205. Provide the "L" output signal from BKPF-202 to an audio distortion meter, and read the level.
BKPF-205 ANALOG IN AUDIO Input to "1" Input to "2" Input to "3" Input to "4" BKPF-202 DIGITAL IN AUDIO Provide an output signal from AES/EBU OUT 1 of BKPF-106A Provide an output signal from AES/EBU OUT 1 of BKPF-106A Provide an output signal from AES/EBU OUT 2 of BKPF-106A Provide an output signal from AES/EBU OUT 2 of BKPF-106A BKPF-202 ANALOG OUT AUDIO "L" becomes effective. "R" becomes effective. "L" becomes effective. "R" becomes effective.
2. Turn 1RV102 (A-4) counterclockwise until the clutch is activated and clicks. Confirm that the level is less than 0 dBm. 3. Turn 1RV102 clockwise until the clutch is activated and clicks. Confirm that the level is more than +18 dBm. 4. Turn RV102 so that the audio output level is +4 ± 0.1 dBm. 5. The ANALOG IN AUDIO 2 through 4 connectors are also the same in procedures as described above. Confirm and adjust the volumes below according to steps 1 through 4. . ANALOG IN AUDIO 2 connector : 1RV202 (A-5) . ANALOG IN AUDIO 3 connector : 1RV302 (A-6) . ANALOG IN AUDIO 4 connector : 1RV402 (A-6)
