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 re-
sult 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. Using equipment that is not capable of 
handling the output wattage may lead to permanent damage.  

 

NOTE: Stewart Audio will not be held responsible for 

damage to your IntraSound System or connected equip-
ment if the instructions in this manual are not followed.

 

 

 

4.2 Indicators and Controls 
 

4.2.1 Indicators and Controls on IS-HUB4 

 
The IS-HUB4 accepts all inputs and power and sends it down Cat5 ca-
ble to the amplifier nodes. All power and system volume can be con-
trolled on the IS-HUB4. 
 
Two LED indicators on the left-hand side of the IS-HUB4 will illuminate 
when power is supplied (Power LED - blue) and when signal is detect-
ed on either input (Sig LED - green). If the nodes are not outputting any 
audio, first check to make sure that both of these LEDs are illuminated. 
 

Note - When the IS-HUB4 goes into sleep mode due to no signal, 
the LED will turn OFF. To turn the IS-HUB4 back on, make sure 
that signal is being sent to the IS-HUB4. 
 

The system volume can be set using the recessed knob on the left-
hand side of the unit. To turn this, insert a small screwdriver into the 
slot and turn clockwise to turn the volume up.

 

4.2.2 Indicators and Controls on IS-AmpNode-10 

 
The IS-AmpNode-10 has an amber LED on the top of the node which 
will illuminate when power is supplied to the node from the hub. 
 

Note - When the IS-HUB4 is in sleep mode, the amber LED indica-
tors on the top of the amplifier nodes will turn off.

 

 
To control the wattage of the amplifier, refer to 

section 3.2.2.
