Input Level Sensitivity (RAVE 161 and 188 only)

Input level sensitivity is the rms analog signal level at which a sinusoidal waveform will produce a digital full scale signal in the device.

The available settings are +24dBu, +18dBu, and +12 dBu (reference: 0 dBu = 0.775 volt), which are 12.3, 6.1, and

3.1volts rms, respectively. These correspond to 17.4, 8.7, and 4.4 volts peak. Check the specifications of the audio equipment driving the inputs to determine the correct setting.

Each channel’s sensitivity is independent of the others and must be set individually.

• First, locate the input sensitivity-selection jumper headers, which are in a row of small groups of pins (6 in each group) on the top side of the circuit board, somewhat midway between the front edge of the board and the rear edge. You’ll see a row of 16 headers on a RAVE 161, or eight on a RAVE 188–one for each channel, in other words.

•Determine what the correct setting should be for each channel, and set the jumpers as shown in the illustration.

There is also a legend printed on the circuit board showing the jumper setting options.

Save any unused jumpers for future use.

Output Levels (RAVE 160 and 188 only)

The output level setting determines the absolute rms level of an analog signal produced by a digital full scale sinusoidal signal.

The four selections available are +24dBu, +18dBu, +12dBu, and +6dBu (reference: 0 dBu = 0.775 volt)—12.3 volts,

6.1volts, 3.1 volts, and 1.5 volts rms, respectively. These voltages respectively correspond to 17.4, 8.7, 4.4, and

2.2volts peak..

•As with setting the input level, the output level for each channel is set by

arranging jumpers on the pins of a header. These headers are located near the rear edge of the circuit board, and there is one header for each analog output: eight in the RAVE 188, and 16 in the RAVE 160.

• Arrange jumpers as shown in this illustration. A legend printed on the circuit board also shows the jumper configurations.

Save any unused jumpers for future use.
