Page 32 Chapter : User’s Guide Mounting and ventilation The USB LED, to the left, indicates a number of APx1701 conditions, detailed in the following table. The APx1701 is designed to mount in a standard 19-inch relay rack, and is fitted with integral rack ears. The USB LED Condition APx1701 is two rack units (2 U) in height.
Page 33 Chapter : User’s Guide resistance cable, such as the ground strap provided with the interface. DUT connections (amplifier outputs) Each channel of the two-channel audio power amplifier in the APx1701 has an output source resistance of approxi- mately 0.13 Ω, including the 0.10 Ω current sense resistor. When one channel is in use, the amplifier is rated at 100 W into 8 Ω, or 60 W into 4 Ω.
