Subject:

Audible tone on output

Applicability:

XTi, CDi, Dsi series amp. Date Code range: Prior August 2006 (0086)

Conditions:

After power up an audible tone may be heard in the speakers.

Part Description:

R809: C.P.N.: A11368-49910 4.99K 1% 0603 SMT Resistor

R810: C.P.N.: A11368-10020 10K 1% 0603 SMT Resistor

R814: C.P.N.: A11368-40220 40.2K 1% 0603 SMT Resistor

Procedure:

1) Place amplifier on bench and remove the top cover using a Torx 15 bit.

2) Locate and replace resistors R809, R810, and R814 with the values listed above.
See Figure 1 below showing the location of the resistors.
