Final Positioning
After correctly connecting the Intermezzo 4.1t and verifying that both the subwoofer and main section portions are playing, it is time to optimize the system for your particular listening room. Earlier, you placed the loudspeakers in their general location. Finding the exact location for optimum performance sometimes only involves moving the speakers up to a few inches in any direction. We urge you, therefore, to experiment with placement until your speakers deliver their full potential. When the speakers are moved inward (toward each other) there is generally better focus of instruments and vocalists; however, moving the speakers too close together can reduce the spaciousness of the stage effect and you may need to experiment with the trade-off between focus and imaging. If your listening room is larger than average and your listening position is relatively far from the speakers, wider placement of the speakers may be required.
ADJUST BIAS PROCEDURE
(Mandatory when any output MOSFET transistors Q305, 310, 320, 321, 306, 307, 311, 312 are replaced)
1. Amplifier should be unplugged and OFF.
2. Remove Amp assembly from cabinet; remove rear plastic guard, and detach entire assembly from black plastic cup containing the controls. All wires exiting the assembly can remain connected unless they will prevent you from removing the amplifier or accessing potentiometers on the Linear board PCB in the following steps.
3. Identify the Linear board assembly (PCB with the output transistors).
4. Adjust RP301 and RP302 fully counterclockwise. See diagram below.
5. Apply 120 VAC power to unit; turn power switch ON.
6. Verify that LED lights on the front Gain Control dial, unless you have disconnected the plug.
7. Connect voltmeter set to DC millivolt range to twin pins on terminal J303, on Linear board.
8. Verify initial voltage is less then 0.1mV.
9. Adjust RP301 clockwise until voltmeter reads 0.3mV + the initial current from step #8.
10. Adjust RP302 clockwise until voltmeter now reads 0.6mV + the initial current from step #8.
11. Turn amplifier OFF. Disconnect AC power to unit.
12. Remove voltmeter from terminal J303.
13. Replace assembly to black plastic cup containing the controls (be sure to reattach green ground wire to one screw); replace rear plastic guard, any wires if disconnected, and replace amplifier back into cabinet.

INFINITY TSS -SUB4000 - POWER AMP SCHEMATIC (CIRCUIT DIAGRAM)
The main power transformer (toroid) part: 150-r1107010in the TSS-SUB4000 is not mounted in the amplifier inside the amp cover, but mounted in the cabinet in a separate location. To replace the power transformer, it is necessary to remove the woofer from the cabinet. The mounting bolt and transformer itself is mounted on an internal brace; both are accessible through the woofer opening.
Troubleshooting:
To keep the circuit “live” while exposing the amplifier components, the amplifier cannot completely be removed and powered up outside the cabinet due to the power connections to the externally mounted transformer. Instead, an alternate method is to leave the amp cover in place and remove the four Phillips screws holding the amp ass’y to the amp cover. Then the amplifier can be partially removed for access, while maintaining the power connections. Unplugging the LED connection (red/black wires) at the PCB plug will allow the amp to be removed even further.
