2. Place the speakers in the center of the room.
3. Depress the MONO pushswitch and playa re-
cord (or radio or tape) with strong bass tones
at a low volume level. Center the BALANCE
control.
4. Position the speakers about six inches apart,
face-to-face. Listen, particularly to the appar-
ent loudness of the bass tones.
5. Next, turn off all power, but do not disturb the
VOLUME or BALANCE settings. Reverse the
connections on the right speaker only. Turn on
the power and listen again. If the bass tones
now seem louder than in (3), you have correct-
ed the phasing between the speakers. If the
bass notes now sound softer, turn off the
power and reconnect the speakers as they had
been originally.
6. If an additional pair of speakers is used along
with the main speaker system, check phasing
between the remote speakers and the main
speakers. Use the BALANCE control to play
only two speakers at once, and invert the
wiring on the remote speakers as necessary.
Do not change the connections on the main
speaker system.
7. Once having phased all speakers, you need not
repeat this procedure in the future if you now
mark the speaker connections and/or cables.
Any method of coding is satisfactory, provided
it enables you, in the future, to duplicate your
now-correct hookup b~tween speakers and am-
plifier.
Use caution when connecting your Model 2252 to
~ a loudspeaker with built-in power supply such as
'an electrostatic loudspeaker. The "common"
connection terminal of such a speaker may' be
capacitively coupled to ground through its own
power supply. To protect the Model 2252 from
distortion and possible overload, make sure the
(-) terminals of the Model 2252 are connected to
the "common" terminals of such a loudspeaker
system.
CAUTION: NEVER DIRECTLY CONNECT THE
LOUDSPEAKER TERMINALS OF
ONE CHANNEL IN PARALLEL
WITH THOSE OF ANY OTHER.
ANY RESULTING DAMAGE IS NOT
COVERED UNDER WARRANTY.
NOTE: Do not use 4 ohm speakers if main and
remote speakers are to be uSed simu
1-
taneously. Use 8 or 16 ohm speakers
only.
CONNECTION TO AC OUTLET
With the front panel POWER pushswitch "OUT",
plug the line cord into an electrical outlet supply-
ing the proper voltage.
CAUTION: DO NOT PLUG YOUR MODEL
2252 INTO A DC OUTLET, AS
SERIOUS DAMAGE WI LL OCCUR.
CONVENIENCE OUTLETS
One UNSWITCHED and one SWITCHED AC
OUTLET are provided on the rear panel for pow-
ering associated components of your system (tape
recorder, record player, etc.).
AC PROTECTOR FUSE
This feature automatically disconnects AC power
in the event of a power source or circuit overload.
If the POWER pushswitch is activated and the
front panel fails to illuminate and no sound is
heard through the speakers, turn off the power
and unscrew the fuse holder on the rear panel and
visually inspect the fuse to see if the internal con-
ducting filament has opened. If so, replace the
fuse with one having the same specifications. See
"Fuse Replacement", page 11.
