4.0 Audio input and output
The chapter discusses ACE-RIU audio input and output specifications.
4.1 Audio input
The ACE-RIU is capable of receiving audio inputs from a wide variety of devices, such as
microphones (freestanding and headset mics), PC sound cards, VCRs, and tape drives. The
nominal input impedance of each stage is 1 k.
4.1.1 Input gains
To adjust the input gains, you will need to access the ACE-RIU internal board. Go to Section
8.0, "Additional information" on page 18 for instructions. The input gains for each channel
are set using jumper blocks J1 (ChA), J2 (ChB), J3 (ChC) and J4 (ChD). Gain values are: no
jumper = 0 dB (line level input), 20, 30, 40, or 60 dB.
