NEW LEVEL STUDIO POWER
Expensive-sounding discrete mic preamps and vintage gear emulation
The Antelope Audio Discrete 4 console-grade discrete microphone preamp interface comes with four 6-transistor discrete
preamps, 121dB dynamic range conversion, and rock-solid clocking. Discrete 4 also features the Antelope Audio premier
real time FPGA FX modeling of iconic studio gear from BAE, Lang, Gyraf Audio, FET, and many more.

1. Safety Notes

To reduce the risk of electrical shocks, fire, and related hazards:
Do not remove screws, cover, or cabinet. There are no user serviceable parts inside. Refer servicing to qualified
service personnel.
Do not expose the device to rain, moisture or spillover of liquid of any kind. Should any form of liquid or a foreign
object enter the device, do not use it. Switch off the device and unplug it from the power source.
Do not use the device until the foreign object is removed or the liquid has completely dried and its residues fully
cleaned up. If in doubt, please consult with the manufacturer.
Do not handle the power cables with wet hands! Make sure the device is switched off when plugging and
unplugging it from the power source.
Avoid placing any objects on the cabinet or using the device in a narrow and poorly ventilated place. Doing so
could affect its operation or the operation of other closely located components. If anything goes wrong, turn off the
device first and unplug the power.
Do not attempt to repair the device yourself: consult authorized service personnel or your dealer.
Do not install the unit near any heat sources such as radiators, stoves, or other apparatus (including amplifiers) that
produce heat.
Do not use harsh chemicals to clean your Unit. Clean only with specialized cleaners for electronics equipment.
Connect all your devices before powering your Unit. This unit is connected via its power cord to the mains safety
earth. Never operate the unit without this earth connection.
Power supply cable should be routed so that it is not likely to be walked on or squeezed by items placed upon or
against it.
To completely turn off the device, unplug the power cable first from the outlet and then from the rear panel of the
unit.
