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

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.
