3.1.2 Output Connections 3 System Installation CAUTION: Before installing your system, make sure that you have read the Important Safety Precautions at the beginning of this manual. 3.1. Hub Installation Stewart Audio recommends that the unit is secured in some fashion to prevent movement of the unit if one of the cables is pulled during installation of an amplifier node. 3.1.1 Input Connections The IS-HUB4 accepts an unbalanced stereo input using either RCA or 3.5mm plugs.
3.2.1 Node Input Connections Gain Configuration The IntraSound system utilizies Cat5 to send power as well as a stereo signal to each node on the line. For the initial connection between the IS-HUB4 and an IS-AmpNode-10, a Cat5 cable should connect any port on the hub with either the left or right port of the node. The remaining port of the node can be used to daisy chain it to another node Caution: Do not connect the final node in a line back to the IS-HUB4. Doing so may damage the hub.
4 Operation 4.1 Operating Precautions 1. Before use, your amplifier must be configured for proper operation, including input and output wiring hookup. Improper wiring can result in damage to equipment or potentially harm to the operator. Consult section 3 for setup instructions. 2. Tampering with the circuitry, or making unauthorized changes is not only dangerous but may also violate local regulations. 3. Use care when making connections between the amplifier and the input or output equipment.
5 Troubleshooting 6 Technical Specifications Maximum Output 20Hz - 20kHz Problem: Hub’s Power indicator does not turn on. Procedure: Check that the hub is plugged into a live outlet. After you have ensured that it is not a power issue, check that you have a hot signal going into the inputs. If a signal is not detected, the hub will go into a sleep mode after 5 minutes to comply with Energy Star. Problem: Amplifier Node’s power indicator does not turn on.
