OPERATING PROCEDURE

Every control on this receiver serves ci 

specific useful function and is

 

important for the

 proper 

operation of your stereo system.

We 

recommend 

that you read the following section carefully so you

 may

 

take full advantage of the performance capabilities of your receiver.

VOLUME CONTROL

The  VOLUME  control  adjusts  the  signal  level  of  any  program  material  con­

nected  to  your  stereo  receiver.  It  is  a  two  section  control  which  simultaneously 

adjusts  both  channels,  and  its  close  tracking  specifications  insure  that  the  relative 

volume level of each channel will be identical.

BALANCE CONTROL

The  nature  of  stereo  reproduction  is  such  that  it  requires  two  identical 

channels  to  attain  the  highest  degree  of  faithfulness  and  spatial  distribution. 

Any  variation  in  the  efficiency  of  one  channel  as  compared  to  the  other  will 
disturb  this  relationship.  Since  there  may  be  slight  differences  between  the  two 
speakers,  the  tape  heads,  etc.,  your  receiver  includes  a  control  to  balance  one 

channel  against  the  other.  Sufficient  range  is  covered  by  this  control  to  permit 

rebalancing  of  the  overall  system  even  in  cases  where  major  unbalance  exists. 
This  control  may  be  set  anywhere  within  its  range  to  attain  system  balance.  It 

does not necessarily have to be set in the exact vertical position.

When  the  BALANCE  control  is  properly  set,  the  apparent  sound  source  will 

lie  in  a  broad  area  between  the  two  speakers.  When  the  BALANCE  control  is 
rotated  to  the  right  the  sound  will  move  to  the  right  and  when  the  control  is 

rotated to the left, the sound will move to the left.

BASS AND TREBLE CONTROLS

The  BASS  and  TREBLE  controls  on  your  receiver  provide  the  full  range 

of  tonal  adjustment  necessary  for  stereo  high  fidelity  listening.  The  tone  control 
range  is  considerable  and  can  adequately  adjust  the  low  and  high  frequencies 
in  accordance  with  your  listening  preference,  speaker  characteristics  and  room 

acoustics.

You may adjust both the BASS and TREBLE for each channel simultaneously 

or  individually.  The  outer  knob  adjusts  the  LEFT  channel  and  the  inner  knob 
adjust  the  RIGHT  channel.  In  order  to  adjust  both  channels  turn  either  knob.  In 

order to adjust one channel only simply hold one knob while adjusting the other.

MODE SWITCH

The  MODE  switch  selects  between  stereophonic  and  monophonic  operation 

depending upon the program source. The switch has five positions as follows:

1)  REV......................... To  reverse left and right channels for your listening

preference

2)  STEREO ............... Normal stereo operation

3)  L & R...................... Combined left plus right channels

4) L .................. ..........  Left channel signal to L & R channel

51 R ......................... . Right channel signal to L & R channel

FUNCTION SWITCH

The  FUNCTION  switch  has  six  positions  and  is  used  to  select  the  desired 

type of program source.

1 ) PHONO 1 (with RIAA equalization)

2)  PHONO 2 (with RIAA equalization)

3)  AM

4)  FM

5)  AUX 1

6)  AUX 2

There  are  eleven  remaining 

switches  on  the  front

  panel  of 

your

  receiver.

 

The switches used are all of the PUSH/PUSH type; that is push in to

 activate

 

the circuit and push again to

 release 

or de-activate the circuit. In describing

 

these  switches  we  will  consider  the

 “

IN”  position  to  be “ON”  and the

 

“OUT” position to be “OFF”.

POWER SWITCH

The  POWER  switch  performs  the  function  as  its  name  denotes.  It  supplies 

power  to  the  receiver  and  to  the  switched  AC  convenience  outlet.  When  the 

switch is ON, function indicator lights will be illuminated.

If  the  function  switch  is  in  either  the  AM  or  FM  position,  the  dial  scale  and 

tuning meters will also be illuminated.
