sieakers are capable of handlingextreme power. They are specially
designed,utilizing a high-temperatureexpoxy..However, when using the
ampl-ifier

in conjunction with each other: GAIN- CONTOT
R - BASS DRIVE
16. GAIN Potentiorneter:
to activate this circuit, s:witchon GAINpot (this auto-
matically deactivates CH l). This control by itself only affects volume.
17. CONTOUR: when adding CONTO(R, you will boost different upper frequen-
cies as you rotate the dial.
18. BASS DRIVE:tuming up the BASS DRI\rEadds low-end frequencies to the
sound you will hear as you tum up this control. Remember, these three
controls work as partners, not individually. Once you have the setting you
like, .youcan tum up the GAINto control volume. This SONICCIRC[JIT
is
a separateentity and has nothing to do with CH l. You will hear that this
SONICBASS CIRCUIT
is even warrner than the regular CH I POLYTONE
sound if that is possible!. Don't forget: the MASTER
VOLthrE must be
turned up for the preamp to be active.

CORD: for your safety, we usiea three-wire line with a ground. lt
is not a good idea to rernoye the ground pin under any circumstances. lf
it is necessaryto operate the amp with the old 2 prong plugs, a suitable
adapter sfrould be used. Operating amp with the proper grounding
receptacle reduces hazard of sftock.
5. RJSE: located in the cap of the fuseholder, this sftould be replaced with
one of proper value strouldit fail. In order to keep the guarantee in effect,
you must replace this fuse with the correct rating, otherwise the warranty
will be voided. Should your amplifier repeatedly blow fuses, take it to
your nearest qualified service center for repair. FLrSERATING:
