16-Line Voice Recorder Card

Product Description

VN series recording card contains two types, such as: VN08S/PCI and VN16S/PCI. VN08S/ VN16S provides 8/16-port independent voice channels in a single slot, can use with different recording modules for high-impendence recording and microphone recording to analog line.

Function
1. Support PCI 3.3V and 5V
2. Support multi-channel recording of different format
3. Flexible configuration
High-impedance recording module: High-impedance input interface for line and moving-coil microphone recording
Microphone module: Feed circuit for capacitive microphone recording
4. Voice Monitor Port
Power amplifier voice signal output interface monitors any channel, not take up system channel.
5. Voice Processing Function
Support A-Law\μ -Law\ADPCM\GSM 6.10 voice recording and playback; Support AGC
Support WINDOWS WAV and VOX voice recording and playback
On-board 0#channel integrates analog amplify circuit and output jack for direct connection of earphone and sound box. Voice monitor to appointed channel can be realized via simple function call.
Support DTMF and FSK caller ID function. Driver automatically divides two modules without setting.
6. High-impedance, passive monitoingr. Free configuration
7. Support MP3 CODEC

Feature
1. Unified Vcard Drive Software
Vcard voice card owns intellectual property rights for the high unified driver development platform. The complex call procedures can be analyzed and controlled through simple function call on the driver platform, without having to understand details. It automatically completes the whole process of digital trunk out-dialing call, and rightly recognizes the called party.
2. Unique Hardware Serial Number
The on-board authorization code identification circuit is designed for software safety. A unique Vcard hardware serial number written in firmware to distinguish it from different cards and prevent piracy. The number is available via an easy function call with applications. Users can apply unique authorization code to protect the safety of software.
3. SIMM Jack.
Functional modules connect to main board through SIMM jack. Double contact is more reliable and convenient
4.1000MIPS high performance DSP process capability
5. Level 4 Standard Lightning Resistance Circuit
