If the speaker is lo be placed on a hard
floor, apply the enclosed fell disks to the under
side of each bottom section.
Place a lower section In the first position
that you have decided to try. Fit the upper sec
tion on the lower, lining up the pegs with the
holes. If yon are not bi-amplifying, connect the
jumper cable between the jacks marked “to
woofer" on the upper section to the jacks marked
“woofer input” on the lower section, checking
that the red striped pin o( the plugs are inserted
in the red jacks. See figure 3. Make sure that a
shorting plug is inserted in the jack in the bottom
section labeled “Short for normal mode“. II Ihe
speaker is to be bi-amplified, refer to Ihe section
on bi-amplification below.
Repeal Ihe process with the oilier speaker.
The connectors at the rear of the top sec-
lions marked “input 4 ohms" will accept bare
wire, spade lugs or various “double" banana
connectors such as the Pomona MDP, Ihe
banana connectors having the advantage of
easiest connection arid removal.
The length and type of speaker cable used
in your system will have an audible effect. Under
no circumstances should 'wire of gauge higher
(thinner) than /Mb be used. In general, the longer
the lenglh used, the greater the necessity of a
lower gauge, and the lower Ihe gauge, the better
Ihe sound, with diminishing returns setting in
around #10 or #12«
A variety of speaker cables are now avail
able whose manufacturers claim better perfor
mance than with standard heavy gauge wire. We
have verified this in some cases, and the im
provements available are ollen more noticeable
than the differences between wires of different
gauge. The differences vary with Ihe amplifier
and speakers used, and il should be noted that
some can damage some amplifiers.
We would also recommend, if possible, that
short runs of speaker cable connect the power
amplifier(s) and speakers and that long inter
connect cables of high quality be used to con
nect the preamplifier and power amplifier. This
of course results in the power amplifiers being
close to the speakers, which may be practically
or cosmetically difficult, but if the lenglh of Ihe
speaker cables can be reduced to a few meters,
sonic advantages may be obtained. The effects
of cables may somelimes be masked il the
equipment is not of the highest quality
Your Typo A's should be wired in phase with
each other. All speaker cables are marked so that
it is possible to distinguish between strands by
color of wire or insulation or by a white stripe or
raised ridge along one strand. H vou are using
one stereo power amplifier (or two mono ampli
tiers) as opposed lo bi-amplifying, conned one
strand to the left channel of your amplifier's
black (or ground) terminal and Ihe other end of
that strand to the black terminal on Ihe rear of
your lull Type A marked “input 4 ohms". Connect
the other strand of that cable lo the other termi
nal (usually red) on the left channel of your
amplifier and to the red terminal on your left
speaker. Connect the other cable between the
right channel on your amplifier and the right
loudspeaker in exactly the same fashion. Should
you be interested in the absolute phase of your
system, a positive voltage at Ihe red terminal on
the Type A will cause all drivers tu move
outward.
Very tight and positive connections are
necessary. If you are using a heavy gauge wire be
careful that as much as possible comes in contact
with the amplifier and speaker terminals.
Save the boxes and all packing, including the
plastic bags. If the speaker should evei require
repair, they will need to he shipped lo the factory
in 1 heir original cartons, using all the packing, or
serious damage will he likely.
Associated Equipment: Proper Selection
and Use
The extraordinary accuracy and transparency
of the Type A allows il to fully reveal Ihe strengths
and weaknesses of the associated audio equip
ment and source material. While the Typo A will
bring to life the sonic delights of state-of-the-art
components, it will with equal clarity bring out any
system flaws. This does not mean that expensive
equipment is a prerequisite to good sound from
the Type A, but rather that Hie equipment must be
wisely selected, and setup with care. The rewards
will be well worth Ihe effort
The phono cartridge is second only to tho
speaker in the extent of its effect on the sound of
Ihe system. The alignment of the cartridge is ex-
tremcly critical. Many of the protractors and guides
supplied by turntable and arm manufacturers are
inadequate or incorrect. Consult your dealer for a
chart relating proper overhang, of (set angle and
the pivot to stylus distance of your arm. Experi
ment with vertical tracking angle and lone arm
damping. Tone arm-cartridge compatibility will
also affect the results you obtain.
Tfie low frequency response of tfie Type A
allows turntable rumble to be mercilessly revealed.
Audible rumble in your turntable (not recorded in
the source) should not be tolerated.
Record warps are reproduced in an audio sys
tem as extreme low frequency Vibrations which
will occasionally overtax a power amplifier or
damage a woofer. If you must play a severely
warped record, Ihe use of a subsonic filler is re
commended. although I hey are not usually sw Ili-
ciently sleep so as to eliminate the problem. Under
other circumstances the audible effects of almost
all subsonic filters make their use inadvisable in a
good system.
A turntable should not be placed so near to
the Type A that vibrations are passed back through
