CAUTION : After servicing this appliance and prior to returning to customer, measure the resistance between either primary AC
cord connector pins ( with unit NOT connected to AC mains and its Power switch ON ), and the face or Front Panel of product and
controls and chassis bottom.
Any resistance measurement less than 1 Megohms should cause unit to be repaired or corrected before AC power is applied, and
verified before it is return to the user/customer.

The relation between the selected surround mode and the input signal
The surround mode is selected with the surround mode b uttons of the SR4200 or the remote control unit. However, the sound from the speakers
depend upon the relationship between the selected surround mode and the input signal. They are as follows;

Notes: 1. SDOS, SMUET, DFS, and LOOP pins are ORed with register data if P/S = L
2. The group 1 and 2 can be selected by DZFM2-0 bits fi P/S= L and DZFE= L .
3. This pin becomes OVF pin if OVFE bit is set to 1 at serial control mode.
4. All input pins should not be left floating.
L : Internal ADC output, H : DAUX input
2
L : 3-wire Serial, H : I
When this pin goes to H , soft mute cycle is initialized.
When returning to L , the output mute releases.
L : Normal Speed, H : Double Speed
No internal bonding.
L : mode 7(disable) at parallel mode,
zero detect mode is selectable by DZFM2-0 bits at aerial mode
H : mode 0(DZF1 is AND of all six channels)
When L ,the AK4527B is powered-down and the control registers are reset to default
state. If the state of P/S or CAD0-1 changes, then the AK4527B must be reset by PDN.
This Pin should be connected to DVSS.
No internal bonding.
H : Full-differential input, L : Single-ended input
When the input data of the group 1 folloW total 8192 LRCK cycles with 0 input
data, this pin goes to H .
This pin goes to H if the analog input of Lch or Rch is overflows.
Large external capacitor around 2.2 F is used to reduce power-supply noise.
When the input data of the group 1 follow total 8192 LRCK cycles with 0 input data,
this pin goes to H
L : Serial control mode, H : Parallel control mode
This Pin should be connected to DVDD at I
12C = L : CCLK (3-wire Serial), 12C = H : SDA (I
Enables digital loop-back from ADC to 3 DACs.
12C= L : CDT1 (3-wire Serial), 12C = H : SDA (I
Enables all 3 DAC channels to be input from SDTI1.
