Audio Inputs, Levels, and Meters
(Headphone, faders, bus selectors,)
These Audio Input Channel Selectors and Level pots are the first stage in the audio signal path. Each
channel carries the audio associated with a video input. Analog audio comes in through the RCA connectors
on the rear panel; audio from the DV input is converted to analog and passed to this bus.
Audio Input Level Calibration Procedure
The first step in setting up the audio for a session with your SE-800 consists of adjusting the levels on each
channel you will be using. To do this, first make sure A+V is not selected. If it is, you will only be able to
adjust the audio for whichever channel is selected on the Main Video Source bus. Set the Audio Bus
Selectors (see below) to both “Video” and “Master” (LED is lit), and push the Master fader to 9 or Max, and
set the other faders to 6 or Unity. Then, select a channel (A, B, C, D) and while listening to the audio and
watching the Audio Level Meters (see below), set the level with the rotary pot so that the sound is
consistently at b3 dB (green LED) and +6 dB (yellow LED) and jusT-Barely peaks occasionally to
+9 dB (red LED). The idea is to avoid any audible distortion (clipping), caused by making the signal level too
high at this stage.
The audio (A, B, C, D) selected at this bus is fed to the main Audio Bus at the Video channel below.
Above three selectors on the left are the inputs (Aux-1, Aux-2, Video), which determine what signals are
present at the Main Output. “Master” button controls the Main Audio Output, if the Master button is not
selected, there will be no audio heard at the output.
