SAFETY PRECAUTIONS

The following check should be performed for the continued protection of the customer and service technician.

LEAKAGE CURRENT CHECK

Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis
resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the
power cord is less than 460 kohms, the unit is defective.

CAUTION IN SERVICING

When you have replaced the 1U-3291 Unit, or changed the CPU, DSP, or their peripheral parts, be sure to perform “RESET”
by pressing S803 on the DSP Unit Ass’y in the state of Standby or Power-on.

WIRE ARRANGEMENT

If wire bundles are untied or moved to perform adjustment or parts replacement etc.,be sure to rearrange them neatly as they
were originally bundled or placed afterward.
Otherwise, incorrect arrangement can be a cause of noise generation.

* fs is a sampling frequency of input digital signal.

e.g.: sampling frequency 48 kHz → fs=48 kHz

* 64fs and 256fs are 64 or 256 times the sampling frequency

respectively.
e.g.:sampling frequency 48 kHz

64fs:48kHz x 64 = 3.072MHz
256fs:48kHz x 256 = 12.288MHz

* The sampling frequency for analog input is fixed to 48kHz internally.

* (No.) indicates the pin number of individual IC.

* The arrow indicates the direction of signal flow. As the input terminal

pointed by the arrowhead and the output terminal by the opposite.

ADJUSTMENT

Audio Section

Idling Current (1U-3356-1, 2)

Required measurement equipment : DC Voltmeter

Preparation

(1) Avoid direct blow from an air conditioner or an electric fan, and adjust the unit at normal room tempereture 15 °C ~ 30 °C

(59 °F ~ 86 °F).

(2) Presetting

 POWER (Power source switch) → OFF
 SPEAKER (Speaker terminal) → No load (Do not connect speaker, dummy resistor, etc.)

Adjustment

(1) Remove top cover and set VR101, VR301, VR401 on 1U-3356-1 (Power Amp L unit), VR102, VR202, VR302, VR402 on

1U-3356-2 (Power Amp. R Unit) at fully counterclockwise (

(2) Connect DC Voltmeter to test points (FRONT-Lch: TP101, FRONT-Rch: TP102, CENTER ch: TP202, SURROUND-Lch:

TP301, SURROUND-Rch: TP302, SURROUND BACK-Lch: TP401, SURROUND BACK-Rch: TP402).

(3) Connect power cord to AC Line, and turn power switch "ON".

(4) Presetting. MASTER VOLUME : "---" counterclockwise (

min.)

MODE : 5CH/7CH STEREO
FUNCTION : CD

(5) Within 2 minutes after the power on, turn VR101 clockwise (

) to adjust the TEST POINT voltage to 2 mV ±0.5 mV DC.

(6) After 10 minutes from the preset above, turn VR101 to set the voltage to 2 mV ±0.5 mV DC.
(7) Adjust the Variable Resistors of other channels in the same way.
