SPEAKERS select ion swi tch to OFF'
@ SPEAKERS SELECTORChange the set t ing of th is swi tch to l is ten through headphones or
in order to choose either of two pairs of connected speakers'
Normal ly , the swi tch should be posi t ioned at A'
OFF . . Use th is set t ing when l is tening through headphones
{no sound comes out of the speakers) '
A . . . . Sound is heard from speakers connected to the A
speaker terminals.
B . . . . Sound is heard from speakers connected to the B
speaker terminals'
@ BASS AND TREBLE CONTROLSUse these controls to adiust the tone. The right one controls treble
and the left one controls bass.
FLAT is the neutra l posi t ion. Turning knob c lockwise accentuates
the bass or t reble, and turning knob counter{ lockwise at tenuates
the bass or treble.
O LouDNEss swlTcHDepress this switch to ON when listening at low volume' Bass and
treble wilt be emphasized to compensate for human listening
characteristics and provide natural listening curve'
@ rape 2/ADAPTOR SWITCHDeoress this switch to ON when using a graphic equalizer or a
second tape deck (or any equipment) connected to the TAPE
2/ADAPTOR terminals.
O TUNER SWITCHPush this switch to listen to an AM or FM broadcast or to record
a radio Program '

@ AUX/vlDEo swlrcHPush this switch to listen to a program source connected to the
AUX/V IDEO te rm ina l s
@ volutvtE CoNTROLTurn this control to adiust the output level of the speakers and
the headphones. Output is minimum at 0 and increases as the
control is turned c lockwise.
C) BALANCE CONTROLThis contro l should normal ly be set to 5. When the output f rom
the left and right speakers or headphones is not the same, adiust
by turning the contro l c lockwise or counterc lockwise'
GD SUBSONIC SWITCHSet th is swi tch to the "15 Hz" posi t ion when l is tening to records'
I t serves 1o at tenuate f requencies lornær than 1 5 Hz and, therefore,
it can be used to suppress the ultra-low-range noise which is
generated by record warp and other factors. When listening to
program sources other than records, set this switch to OFF'
@ MODE SWITCHThis swi tch should normal ly be set to STE REO.
STEREO. Set here lor ordinary stereo l is tening of a stereo-
phonic source.
MONO. Set here to l is ten to a monaural source. The lef t

1. Poner el control de volumen (VOLUME) en suposiciôn de nivel minimo, conectar la alimenta-ciôn y esperar unos 10 minutos.
2. Conectar un voltfmetro de CC a los terminalesTP (canal lzq.; TPl @ y TP2 O , canal Der.;TP4 @ yTPS O )delconjuntoA.F.
3. Comprobar que la tensiôn entre TPl y TP2(canal Izq.) esté dentro del margen de 4,5 mV- 100 mV CC. Luego rcalizar una comprobaciônsimilar para el canal i)er. (entre TP3 y TP4).Si la tensiôn es menor de 4,5 mV, cortar laconexiôn provisional A (canal Lzq.\, y conectarprovisionalmente B (canal Der.). Si la tensiônexcede de 100 mV, comprobar que no hayaninguna averfa en el circuito.
