Black Lion Audio 1800 W Cuyler Ave., Suite 2 East Chicago, IL 60613 773-549-1885 V1.
WARNING FOR YOUR SAFTEY, PLEASE READ THE FOLLOWING: GROUNDING: For your safety, do not defeat the grounding connection on the power cord. Use the device only when it is properly grounded. WARNING: If the safety ground on the device is defeated, a fault condition in the unit or in the system to which it is connected could result in full line voltage between chassis and earth ground potential. Severe injury or death can result.

I. Overview The analog to digital converter (ADC) is a vital component in any recording or broadcast studio. Limitations of the ADC can compromise the performance of the whole system. Inter-modulation distortion (often referred to as IM or IMD), harmonic distortion (THD), and frequency or phase response anomalies, may manifest themselves as an overall deterioration in the perceived sound quality of the system.
II. Installation / Connections AFTER YOU HAVE UNPACKED THE UNIT Save all the packing materials - they will be handy should it become necessary to transport or ship this device. Please inspect this unit carefully for any signs of damage incurred during transportation. It has undergone thorough inspection and testing prior to packing and was shipped in perfect condition. If, however, there are any signs of damage, notify the transportation company without delay.
III. Inputs and Outputs 1. Power, Power Switch, and Power LED Make sure the voltage selector switch on the IEC connector is set to the appropriate voltage for your locale. Power can be 50Hz or 60Hz, and the voltage selections available are 110V and 240V. The voltage indicator indicates the selected mains voltage. The power switch on the front of the unit applies power to the unit’s internal power supply. A power LED is located on the front panel below the power switch.
Note that at all settings, the actual signal level which will clip the converter (possibly causing unwanted distortion) is typically 15dB over the level set on the front panel. Thus, in the “-10” setting, a peak signal of greater than +5dBV will clip the unit. In the “-3” setting, a signal greater than +12dBV will cause clipping, and so on. To assist in setting the appropriate input level for your application, Signal/Clip LEDs are located on the front panel.
source is selected (and the clock is present), the ADC will detect it on the “Word In” BNC connector on the rear panel. For convenience, when the ADC has detected and synchronized to a valid clock source, internal or external, a “Lock” light (labeled “WC” for word clock. will illuminate on the front panel of the unit. In the case of an external clock source, this light indicates that the clock signal is being received successfully.
termination of a transmission line (like a clock distribution line, for instance) is as follows: A proper termination tells the signal to stop! Black Lion Audio clocks are terminated at the source (the clock output) with a 75 Ohm termination. This is done to properly drive a 75 Ohm cable and has the effect of “killing” any reflections that come back from the line. Reflections are most commonly caused by unterminated “stubs” on the line, like an unterminated clock input for instance.
