Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Acrylic Base/Platter: The
Marantz TT-15S1 Reference Series turntable features a low-resonance,
high-density acrylic chassis and platter. The chassis is 17-5/16" wide x
13-11/16" deep x 3/4" thick. The platter is 11-11/16" in diameter and 1-1/8"
thick. The turntable is supported by three solid aluminum feet. The feet are
adjustable, so the turntable can be leveled.
Assembly Required: The
turntable is packed unassembled in thick foam rubber. The platter, tone arm, and
cartridge must all be mounted to the turntable base before use.
Motor: The TT-15S1's non-servo
controlled AC motor is float-mounted in the left rear corner of the turntable
base. To prevent vibration, the motor actually rests on the table top, and
protrudes through a hole in the base. A silicon band completely isolates the
motor from the turntable base.
Belt Drive: The turntable
features a belt drive system, and comes with 2 endless silicon belts (one is a
spare). The pulley, which slips onto the motor shaft, has two grooves with
different diameters for the two rotating speeds (33-1/3 rpm and 45 rpm). To change the speed, you must manually move the silicon belt from one groove to the other.
Tone Arm: The TT-15S1 features
an anodized aluminum, straight tone arm. The low-coloration tone arm has a
magnetic anti-skating mechanism and a fine adjustable counter weight. It also
has an attached high quality 39" audio and ground cable. The audio cable has
left and right RCA plugs, and the ground cable has a spade connector. The
counter weight is used to set the proper height of the tone arm.
Cartridge: This Marantz
turntable comes with a 6-gram, high quality ClearAudio Virtuoso ebony wood MM
(moving magnet) stereo cartridge and non-replaceable stylus. The cartridge is
attached to the tone arm via a fixed mount. Tools for mounting the cartridge to
the tone arm are included.
Clever Clamp: The turntable
comes with a Clever Clamp record clamp from Souther Engineering. This 65mm
diameter plastic disc slides over and grips the spindle, locking and clamping
records into place. The upturned edges on the clamp allow for easy removal.

TT-15S1 comes with the following accessories:
- Tool Kit: To help you
assemble the turntable, the tool kit includes 3 Allen wrenches and a

of bearing oil is included for regular maintenance of the turntable. It is

- Turntable Sheet: A 1/8"
thick felt pad is included if you prefer not to place your records directly
on the acrylic platter. A small circular piece of felt is included to assist
you in setting the proper tone arm height when the turntable sheet is used.
- White Cotton Gloves: When
changing turntable speeds, it is recommended that you use the white cotton
gloves when handling the silicon belt to avoid damaging the belt.
