* SPEAKER INSTALLATION:
Your Slereo is designed for use with 2 or 4 speokers
ond the besl performonce is oihieved with lhe use of
molched speokers of 8 or 4 ohm impedonce respeclively.
Mixing speokers of dif Ierent ohmoge con couse mismotch
in lhe impedonce. This will result in poor volume ond lone
quolity.
NOTE, The Stereo unit musl be turned off while instoll-
ing speolers in order lo ovoid domoge lo lhe unit
due lo possible shorling of speoker leods during
inslollolion process.
Fi9.3.
You must olwoys insloll o minimum o{ lwo speokers, one on
lhe right side of the cor ond one on the left to get lhe
proper slereoeffeit. For the ultimote in stereo performonce,
instoll o set of 4 or 8 ohm speokers, two in fronl ond lwo
in reor (righl ond left sides of cor).

{Refer to Fi9. l6)
First remove the escutcheons lblock resin ponels) ond
escutcheon ossemblies. Adiust the orrtput by inserting o
smoll insuloted driver into the omplifier output odiustment
screw holes.
Posilion the knobs so thot the treble is moximum, the boss

METHOD OF ADJUSTMENT.
With the volume ond tone both ot o moximum, turn the
