To connect balanced inputs, insert the +, -, and shield into the header as shown at left.

To connect unbalanced inputs, connect the signal conductor to the + terminal and the shield to the - terminal,

with a jumper to the ground/shield terminal, as shown at below left.

The analog RAVE models (RAVE 160, 161, and 188) use normal analog balanced audio inputs and outputs, with

three terminals per channel: Hi (+), Lo (-) and Shield. Channel numbers and connector pinouts are labeled on the

rear of the unit, as shown in the illustration below. The actual channel assignment depends on the model.

RAVE 188

This model features 16 analog channels comprising eight inputs and eight outputs. The inputs are labeled 1

through 8 on the rear of the unit and are to the right of the outputs, labeled 1 through 8.

RAVE 161

This model features 16 analog audio input channels. They are labeled 1 through 16 on the rear of the unit.

RAVE 160

This model features 16 analog audio output channels. They are labeled 1 through 16 on the rear of the unit.

DIGITAL AUDIO CONNECTIONS

The digital RAVE models (RAVE 80, 81, and 88) use input and/or output interfaces that utilize the AES3 (also known

as AES/EBU) digital audio standard.

All digital audio inputs on a RAVE unit are terminated as dictated by the AES3 specification. Thus, you will

generally need a suitable digital distribution amplifier if any single AES3 source will be driving more than one

AES3 input. Also, all AES3 inputs automatically and independently perform digital sample rate conversion. This

allows any source device to run asynchronously to the network and to other sourcing devices.

Each AES3 input or output carries a pair of digital audio channels through a balanced 3-pin XLR connector. Like

analog equipment, outputs use connectors with male pins and inputs use

connectors with female pins, and Pin 1 is used for the cable shield and the signal

ground. Pins 2 and 3 are for the digital signal, and unlike analog connectors, the

relative polarity of the two pins is not important. Channel numbers and

connectors are labeled on the rear of the unit, as the illustration shows. The

actual channel assignment depends on the model.

RAVE 88

This model features eight AES3 channels (16 audio channels): 4 inputs and 4 outputs. The AES3 inputs are labeled

1 through 4 on the rear of the unit and are to the right of the AES3 outputs 1 through 4.
