How do I listen to LP or 45 RPM records?
Connect the components as shown in the diagram using stereo
RCA cables
to interconnect the turntable to the preamplifier and the preamplifier to
the power amplifier. Physically arrange the components in your choice
of rack or stand [see Note 1], and then buy (or use cables you already
have) that are not overly long. That is, its neater to use a 3 foot
cable when a 3 foot cable is long enough.
Then connect the power amplifier output connectors to the loudspeakers
using speaker cables. I agree with others in
the industry who believe speaker cables should be at least eight feet
long for best sound quality. Technically, this does not make good sense
but I agree that it sounds better.
Although you can buy new turntables that will play LPs, 45 and 78 RPM
records, it is better to avoid them if you are interested in only LPs
or 45s. The three-speed 'tables are primarily DJ equipment with short
pickup arms and don't provide the best performance for LPs and 45s.
(If you want to play all three speeds, it's better to get two
turntables.) Thorens, and perhaps some other companies, does build
a very fine three-speed 'table. But I still suggest it's better to use a
separate 'table for 78s. For the reasons and some turntable suggestions,
please visit our page on
buying audio equipment .
With a turntable as the music source, your preamp must boost the signal
from the pickup cartridge and provide "RIAA" equalization to compensate
for the recording method. I'm suggesting you take a look at our phono
preamps as they offer excellent performance at reasonable prices.
TDL® Model 403 Battery-powered RIAA
TDL® Model 4041 Battery or mains-powered
RIAA (rack mount)
TDL® Model 407 Battery-powered universal
TDL® Model 408 Mains-powered universal
TDL® Model 409 Mains-powered RIAA
Plug the cables from the turntable into the "Phono" connectors on the
preamp and set the selection switch to "Phono". (If you are using a TDL®
preamp, connect the cables to the "Input" connectors. Some
turntables provide a separate wire that connects to the 'table frame.
Connecting this wire to the blue binding post usually results in
better performance by lowering the noise that is picked up.) Reading
the Phono section of your preamp User Guide or Owner's Manual is also
a good idea!
Loudspeaker placement is field of study in itself. Sometimes the room
simply dictates where you will have to place the 'speakers but it's
better if you can experiment with placement for best sound quality.
There is a lot of information on the web and I'm listing some sites
that may be useful. Also, if you are technically inclined, CaraCAD
is an example of some inexpensive computer software that can help with
room analysis for best 'speaker placement.

Note 1: Audio Advisor, Inc. has a large variety of audio component racks
and stands. You can call 800-942-0220 to request a copy of their printed
catalog or you can visit them online at
www.audioadvisor.com . Stands
that are all-metal should be avoided because they tend to vibrate which adds
unpleasant sounds to your music! Wood or wood-composition shelves with
wood or metal supports work fine.
