CL32(A3032) Alignment procedure
1)
Put the power switch on, and ensure that the pilot lamp lights up.
2)
Check the voltage at the points shown in the attached sheet(page 2)Fig.l and 2
each voltage is within : 201 deviation of the specified value.
3)Set each operation knob and switch as per the following standard condition.

grant Panel
A.Input selector switch at Phone 1.

B.Monitor switch Source
' C.Tape dubbing switch Source
D.Mode switch Stereo
E.Liner Equalizer switch Center
F.Filter switch Defeat
G.Balance control Knob Center
H.Attenuator Switch Normal
I.0utput Selector switch A+B
J.Volume switch Minimum

Rear Panel

A.Input impedance adjustment switch at 50Kohms

B.Input level set volume(tuner) at Max(clockwise to the maximum)

C.Input level set volume(Aux 2) at Max(counter-clockwise to the maximum)

0)

Connect the milivolt meter and oscilloscope to the output terminal A and
gradually turn the volume control in clockwise direction to check residual
noise increase accordingly.

5)
Insert the short-pin plug to the phone 2 input terminal.

6)
Set the input selector to the Phono 2 position.

7)

Ensure that the noise level is within the rated specification.

8)
Set the input selector to AUX 1 and AUX 2 and ensure the noise level is
within the rated specifications respectively.

9)

Set the input selector to the tuner position and ensure the selector switch

to the tuner position and connect an audio signal generator to the tuner

terminal. Then, ensure that the frequency response, distortion and input sensitiviq
and Liner equalizer satisfy the specifications.

11)
Repeat the step (10) on the AUX 1 and AUX 2 terminals.

12)Connect a milivolt meter, oscilloscope and distortion meter to the Rec-out
terminal. Then, ensure that the distortion, frequency response and input
sensitivity of the equalizer stage satisfy the required specifications.
