The ORBAN OPTICODEC 7600, designed and engineered by our German engineering team in Ludwigsburg, is the next step forward in audio transmission using ISDN - X.21 - V.35 and TCP/IP. The ORBAN OPTICODEC 7600 is the natural successor of one of the most used codecs the MusicTAXI.

The OPTICODEC 7600 is an extremely powerful codec using the latest MOTOROLA DSP (we do not use PC processors). With our unique AUTOMATIC CODEC DETECT function, you do not have to worry about what codec is on the other side.

A few years ago we started our cooperation with AETA France and as a result we offer full AETA 4SB ADPCM compatibility. AETA ADPCM is the perfect codec when transmitting sports-events. The delay is less than 7 ms.

When using OPTICODEC 7600 on a LAN/WAN/ATM/Internet you will appreciate our Windows 2000/XP based NETControl remote control software. NETControl allows you to monitor/configure and connect any ORBAN OPTICODEC connected to your network.

The OPTICODEC comes with up to 3x ISDN (64 - 384 kbps) , 1x X.21/V.35 - 10/100 BaseT - Alarm/Control Interface - Remote Port / Ancillary Data Port over RS232 or USB Full speed - External Sync on BNC - AES/EBU and Analog I/O on XLR.

Features

• Multifunctional Keypad
• Customizable Direct Dial Keys for algorithms
• Cursor Positioning: Up, Down, Left, Right
• Numeric Keypad, Help, Redial, Quick Dial, Hang Up
• Display Contrast and Headphones Loudness Adjustment

We currently support the following algorithms: MPEG 1 Layer II and III - MPEG 2 Layer II and III - Linear 8, 12, 16, 20 and 24 bits - 4SB ADPCM (AETA standard) - G.711 - G.722.

The new 7600 is one of the easiest codecs to work with, whether you are using only the front panel control, or our OPTICODEC-PC remote.

Everything is straight forward. Simplicity comes first!
