[. . . ] Do not attempt to service the unit yourself. Refer all servicing to qualified personnel. Opening the chassis for any reason will void the manufacturer's warranty. If liquid is spilled on the unit, shut it off immediately and take it to a dealer for service. [. . . ] Connect the AC power cord to the AC power receptacle on the back of the unit. Route the AC power cord to a convenient power outlet away from audio lines. The unit may be turned on and off from the rear panel power switch or from a master equipment power switch. 2. 2 Connection to a Mixing Console 1). Connect your mic cable to the Mic input of the E-800 NOTE: If you are using a mic with a separate power supply, such as a tube microphone, make sure that you are not sending two sources of +48V phantom power to the mic. Use the +48V from the mic's power supply. Use the +48V Phantom Power switch on the E-800 for all other microphones which require phantom power. 2). Set the front panel of the E-800 to the desired settings, including phantom power, 20 dB pad, phase, etc. Connect the line output of the E-800 to the console's LINE INPUT, and ensure that the console's input selection switch is set to LINE, and the console's gain control is set appropriately low. ® 8 3E-800 User Manual E-800 Analog Applications Section 2 3). Turn the E-800's DRIVE control to the minimum position. Turn the OUTPUT LEVEL control to the 12 o'clock position, and apply power to the E-800. Make sure your console's gain fader is at the nominal level and begin to slowly increase the gain of the E-800 using the DRIVE control.

NOTE: Although digital information is coming out of both XLR and RCA jacks simultaneously, the correct format will only appear at the output for the format type selected. For example, if you have AES/EBU format selected, an AES/EBU formatted signal will appear at the output of both the XLR and the RCA connector. Or, if you have S/PDIF format selected, an S/PDIF formatted signal will appear at the output of both the RCA and XLR connectors. Sync In and Out Connectors BNC connectors are provided for both word clock in and out functions. The E-800's clock chips are dbx custom VCXO chips, designed for low-jitter performance. You may use the E-800 as a master clock source, having other equipment slave to the E-800, or you may slave the E-800's clock to any other word clock source. 3. 3 Sync Input Sample Rate Selection When connecting an incoming or master device to the sync input of the E-800, the E-800 will automatically lock to the sample rate of the master device. The sample rate will then be indicated in the SAMPLE RATE select button. Note that when the master device is disconnected from the Sync Input connection, the SAMPLE RATE select button will flash until an internal sample rate is selected. ® E-800 User Manual 13 Section 3 Digital Applications E-800 3. 4 Direct Connection to a DAW (CPU) S/PDIF Rear Panel Connections · · Connect the source to the desired 1/4" TRS or XLR input.

[. . . ] Another advantage of the logarithmic mapping of our dbx Type IVTM Conversion System is that it preserves the highfrequency detail of the signal in the overload region. 3a through 3d illustrate what happens when you overload an A/D converter without Type IVTM. 3a shows an input signal having both low-frequency and high-frequency components. When the signal overloads, or clips, (Fig. [. . . ]
