Getting Started
READ THIS PAGE!!
Even if you�re one of those people who never reads manuals, all we ask is that you read this page now before you begin using the Onyx 800R. You�ll be glad you did!
Set the Levels
To set the channel GAIN controls, it�s not even necessary to hear what you�re doing at the outputs of the preampli�er. The following steps must be performed one channel at a time. 1. Play something into the selected input. This could be an instrument, a singing or speaking voice, or a line input such as a CD player or tape recorder output. Be sure that the volume of the input source is the same as it would be during normal use. If it isn�t, you might have to readjust these levels later. Adjust the channel�s GAIN control so that the ��20� and �0� LEDs light frequently or continuously, and the �OL� LED doesn�t light at all (or only �ashes occasionally). Repeat for each channel.
Zero the Controls
1. 2. 3. Turn down the channel GAIN controls. Set all push button switches to their �out� positions. Turn the POWER switch off. 2.
Connections
If you already know how you want to connect the Onyx 800R, go ahead and connect the inputs and outputs the way you want them. If you just want to get sound through the preamp, follow these steps: 1. 2. Plug a microphone into channel 1�s MIC input. Connect the analog line outputs to your MDM, HDR, or audio interface for your DAW. This requires either a DB25-to-DB25 audio cable or a DB25 breakout cable to either eight male XLR plugs or eight 1/4" TRS plugs. You can connect the Toslink OPTICAL OUT connectors to your recording equipment if they are equipped with Toslink ADAT optical connectors. All eight channels are always present at the LINE LEVEL OUTPUTS and the OPTICAL OUTs up to 96 kHz sampling (four channels at the OPTICAL OUTs at 176.4/192 kHz). You can connect the DB25 AES/EBU OR S/PDIF OUT connector to your recording equipment if they are so equipped, but we recommend that you �rst read the section on pages 14-15 that describes this output and its associated buttons. Note: When using the OPTICAL OUTs or the AES/EBU OR S/PDIF OUT, make sure your MDM, HDR, or other audio interface is con�gured to clock off the incoming digital source. If you try to use their internal clocks, it�s simply not going to work right. 5. 6. Plug in the detachable linecord, connect it to an AC outlet, and turn on the Onyx 800R�s POWER switch. If the microphone is a dynamic microphone, set the impedance switch on channel 1 to the �D� position (2400 �). If it�s a condenser microphone, set the impedance switch to the �D� position (or to the manufacturers recommended impedance setting) and push in the 48V phantom power button to turn on the phantom power for channel 1. � � 3.
Start Recording
1. You should now see the signals from the Onyx 800R appearing on the meters in your MDM, HDR, or DAW. Start recording and hear the Onyx 800R in stunning crystal clarity.
Other Nuggets of Wisdom
� You can connect the analog outputs from any linelevel source to the LINE LEVEL INPUTS on the Onyx 800R and use its high-quality analog-to-digital converters to get your analog signals to your digital recorder(s). Always turn the Onyx 800R off before making or changing connections. When you shut down your equipment, turn off the ampli�ers �rst. When powering up, turn on the ampli�ers last. Never listen to loud music for prolonged periods. Please see the Safety Instructions on page 2 for information on hearing protection. Save the shipping box! You may need it someday, and you don�t want to have to pay for another one.

That�s it for the �Getting Started� section. Next comes the �Hookup� section that shows you some typical ways that you might use the Onyx 800R in real applications. After that, you can take the grand tour of the Onyx 800R, with descriptions of every knob, button, input, and output. We encourage you to take the time to read all of the feature descriptions, but at least you know it�s there if you have any questions. Owner�s Manual
