N. A/D DATA CHECK
This menu is used to display the A/D conversion
value of the microprocessor which detects panel
keys of the main unit and protection functions in
using the sub-menu.
When K0/K1 menu is selected, keys become non-
operable due to detection of the values of all keys.
However, it is possible to advance to the next
sub-menu by turning the VOLUME of the main
unit. When using this function, note that turning
the VOLUME more than 1 click would cause the
volume value to change.
During signal processing, the condition before ex-
ecution is maintained.
* The figures in the diagram are given as refer-
ence only.
N1PD: 45DI: 0
PD/DI
PD: PRD (Power amplifier DC protection detection)
The output of power amplifier DC (DC voltage)
is detected.
Normal value: 27 to 89 (Reference volt-
age: 3.3 V=255)
* If PRD is out of the normal value range,
the protection function works to turn off
the power.
DI: DOCK ID (DOCK ID detection)
The output of DOCK ID is detected.
(Reference voltage: 3.3 V=255)
V1/V2
V1: PRV1 (Voltage protection detection)
Voltage detects: ACL, 10V, VP, +6.3H and
+3.3H
Normal value: 68 to 161 (Reference volt-
age: 3.3 V=255)
V2: PRV2 (Voltage protection detection)
Voltage detects: AC2, +12, -12, +5D, +5I,
+5V and -5V
Normal value: 104 to 181 (Reference volt-
age: 3.3 V=255)
* If PRV1 and PRV2 are out of the normal value
range, the protection function works to turn off the
power.
N. A/DDATACHECK
本機パネルキー、プロテクションなどを検出して
いるマイコンのA/D変換値を、サブメニューで表
示します。
K0/K1のメニューにすると、全キーの値を検出す
るためキー操作はできなくなりますが、本機の
VOLUMEを回すことにより、次のサブメニューに
進めることができます。このとき1クリック以上
回すと、ボリューム値が変化するので注意してく
ださい。
信号処理は実行前の状態を維持します。
図中の数値は参考例です。
V1/V2
V1: PRV1(電圧プロテクションの検出1)
検出電圧: ACL、10V、VP、+6.3H、+3.3H
正常値: 68−161(基準電圧:3.3V=255)
V2: PRV1(電圧プロテクションの検出2)
検出電圧: AC2+12-12+5D、+5I
+5V、-5V
正常値: 104−181(基準電圧:3.3V=255)
PRV1、PRV2は正常値を外れるとプロテクション
が働き、電源オフされます。
PD/DI
PD: PRD(パワーアンプDCプロテクションの検出)
パワーアンプDC(直流電圧)出力の検出。
正常値: 27−89(基準電圧:3.3V=255
PRDは正常値を外れるとプロテクション
が働き、電源オフされます。
DI: DOCKID(DOCKIDの検出)
DOCKID出力の検出。
