How to use the recording level control on the front section

1Set the recording level control on the front section to maximum (10) position.

2Initially, adjust the recording level using the CH1 recording level control on the side.

The GY-DV500 is provided with the microphone connector on the front section and the two AUDIO INPUT connectors at the rear section for audio input.

On the other hand, two channels of sound can be recorded on the tape in digital PCM format.

Using the AUDIO INPUT switch, select for each channel (CH1 and CH2) whether the sound to be recorded should be the sound from the microphone connector on the front section or the sound from the AUDIO INPUT connectors on the rear section.

Selecting the CH-1 channel input sound

Make the selection using the CH-1 AUDIO INPUT switch. FRONT : The sound from the microphone connector on the

front section is recorded on the CH-1 channel. REAR : The sound from the CH-1 AUDIO INPUT

connector on the rear section is recorded on the CH-1 channel.

Selecting the CH-2 channel input sound

Make the selection using the CH-2 AUDIO INPUT switch. FRONT : The sound from the microphone connector on the

front section is recorded on the CH-2 channel. REAR : The sound from the CH-2 AUDIO INPUT

connector on the rear section is recorded on the CH-2 channel.

Selecting the front section's microphone connector

A microphone (phantom microphone, etc.) requiring +48 V power supply or other type of camera microphone (monaural) can be connected.

•In accordance with the connected microphone, specify the phantom microphone or other type of microphone using the Camera Setup Menu item CAM MIC +48V.

•The reference input level is -60 dBs.

Selection of rear audio input connectors

Select the audio signal input to the AUDIO INPUT connector using the [LINE/MIC] switch. Make settings for the CH-1 and CH-2 AUDIO IN connectors separately.

LINE : Set to this position when connected to audio equipment, etc.

The reference input level is +4 dBs.

MIC : Set to this position when using a monaural microphone.

The reference input level is -60 dBs.

MIC +48 V : Set to this position when a microphone (phantom microphone) requiring +48 V DC power supply is connected.

CAUTION:

When connecting a component that does not require +48 V power supply, make sure that the LINE/MIC switch is not set to MIC +48V.

When using the microphone on the front section, set the Camera SETUP screen item “CAM MIC +48V” to “OFF”. Neglecting this could cause damage to the connected component. ☞ See page 77.

•Set the VCR Setup Menu item No. 246 FRONT VOLUME ENABLE to "ENABLE".

CAUTION:

The recording level controls on the side section work regardless of the setting of the VCR Setup Menu item No. 246 FRONT VOLUME ENABLE. ☞ See page 68.

Manual Adjustment of Recording Level

The recording level can be adjusted manually when the GY- DV500 is in the record, record-pause or stop mode.

1. Set the AUDIO SELECT switch of the channel whose recording level that you want to adjust manually to MANUAL.

2. Rotate the recording level control corresponding to the audio input to be adjusted.

•Adjust so that the peak level does not exceed the -3dB point when a loud sound is input.

•With microphone input, since the limiter circuit is activated, the recording level will not exceed 0 dB even if the recording level control is turned up.

3When a loud sound is input during recording, use the recording level control on the front section to lower the recording level.

CAUTION:

When the AUDIO INPUT LINE/MIC switch on the rear section is set to MIC, be sure to check that the microphone is connected to the AUDIO INPUT connector.
