INTRODUCTION

Thank you for purchasing the BASIS AUDIO 2800 Signature Series turntable. We are

confident that you will come to view your decision to use a BASIS turntable as one of the

most musically rewarding equipment choices in your audio experience.

The incredible precision of the BASIS bearing and platter system will allow you to feel

the emotion of the music’s natural flow. The unequaled effectiveness of the BASIS fluid-

damped suspension will open up your system’s soundstage, letting you hear low-level

details such as echoes deep in the sound field more clearly than you have experienced

before. Each instrument’s natural timbre will be portrayed with uncanny realism, and the

entire presentation will be without the exaggeration and artificial air that the resonances

of lesser designs create. Our goal at BASIS is that this effortlessness and realism allow

you to relax and appreciate the music more than you ever have before.

To realize the potential of your new turntable, and to prevent any damage which would

delay your enjoyment, please carefully read these instructions before attempting to

assemble your 2800. A 2200 Set-up DVD is also provided to show you a very similar

set-up process, and a link to the video can be found at https://www.basisaudio.com/2200

UNPACKING AND SETTING UP YOUR 2800 TURNTABLE

NOTE: You will find some white cotton gloves packed with your turntable. You may

wish to use the gloves while you are handling the acrylic pieces of the turntable to

prevent fingerprinting and scratching of your finely finished Basis turntable.

You will also find a bubble level, which will help you when you are leveling the turntable.

1. Locate the box labeled “2800 Bearing Assembly”.

2. Unpack the bearing.

3. In the accessories box, locate the four 10-32 X 1/2” long bearing screws and the

hex wrench that fits these screws.

4. In the vacuum accessories box locate the hose which has an aluminum “elbow” on

the end. There is a short section of very soft clear hose between the elbow and the

gray hose to further isolate the turntable from any room vibration. Be sure that this

soft hose is not kinked or twisted. Note the rectangular notch or cutout in the

bottom of the bearing housing. Next to the notch is the ground wire connector and

associated screw. Note that the round protrusion on the vacuum elbow has a

rubber sealing ring, or “0-ring”, on it. Also note that at the bottom of the notch in

the bearing is a hole into which the round protrusion on the elbow fits. You will be

fully inserting the elbow into this notch and hole after the bearing has been

mounted into the turntable. We are pointing out these features here as the bearing

is easier to inspect before it is installed in the subchassis, and so that you may

visualize how this elbow fits into the bearing before you get to that step.

5. Unpack the subchassis. CAUTION: take care not to cut into the subchassis when

opening the package. If you use a knife to cut the tape, cut just deep enough to

cut the tape.

6. Fit the bearing into the top of the subchassis. Look at the back side of the bearing

and make sure that the notch for the vacuum elbow points more toward the rear of

the turntable than the front. If not, rotate the entire bearing assembly, and then

note the mounting holes in the bearing and line them up with the holes in the

subchassis. Confirm again that the notch for the elbow points toward the rear. Now

look at the top of the subchassis. Note that the rotating part of the top of the

bearing has a notch that allows you to access each bearing screw location as you

rotate the top of the bearing. Rotate the bearing so that the mounting holes in the

bearing line up with the holes in the subchassis. Align the notch to one of the screw

locations. Install the screw and turn the screw with the wrench until it is just barely

snug. Repeat this with the other 3 screws. CAUTION: DO NOT TOUCH THE

SCREWS ON THE TOP OF THE ROTATING BEARING. TO DO SO WILL RUIN

THE BEARING ALIGNMENT AND IS NOT COVERED BY WARRANTY.

7. After the 4 screws are installed and lightly tightened go back and tighten each

screw snugly using only the short side of the wrench for leverage. THESE

SCREWS DO NOT NEED TO BE SEVERELY TIGHTENED. EXCESS FORCE

COULD STRIP THE THREADS IN THE SUBCHASSIS.

8. Remove the grounding screw and wire from the bottom of the bearing using the

small wrench supplied in the accessories box. Install the vacuum elbow. The elbow

is fully inserted when the bottom surface of the elbow is “flush”, or even, with the

bottom of the bearing. You may have to push the elbow firmly, while “wiggling” it,

to facilitate the compression and insertion of the 0-ring. This 0-ring must fit tightly

to insure a good seal. With enough force, which should be easily accomplished by

hand and without tools, the elbow will press into place, possibly accompanied with

a “snap” as the elbow bottoms out after the 0-ring suddenly complies. Install the

grounding screw and wire. The screw locks the elbow in place in addition to

connecting the ground wire.

9. Locate the “Resonance Annihilator”support pod boxes. Open the 2 boxes and

unwrap the 4 pods. Note that each pod is calibrated and marked for a specific

corner of the turntable: LR for left rear, RR for right rear, LF for left front, and RF for

right front.

10. Using the hex key that is packed in the acessories box unscrew all of the screws in

the top of the pods. WHILE UNSCREWING THE SCREWS KEEP STEADY

PRESSURE ON THE TOP OF THE POD WITH THE OTHER HAND SO THAT

THE POD WILL NOT TRY TO OPEN UNTIL YOU HAVE REMOVED BOTH OF

THE SCREWS.

AFTER REMOVING THE SCREWS, THE PODS MUST BE KEPT UPRIGHT OR

SILICONE DAMPING FLUID WILL SPILL OUT.

11. After removing the screws the tops to the pods will pop up. Pack the shipping

screws and nylon washers in a zip-lock bag and save them. You will need these

screws in the future for packing and shipping the turntable.

NOTE: At this point you may wish to obtain some paper towels to neaten the

appearance of the pods. Note that when the shipping screws are removed and the pods

are extended you can see into the pods from the side. Some silicone fluid may have

been deposited on the top edge of the pod (the surface containing the threaded holes),

as well as on the underside of the pod cover and on the 0-ring area of the pod cover. If

you wipe these surfaces no additional fluid will be deposited on them as long as the

pods are in the open position. For cleaning silicone fluid a commercial cleaner called

“Simple Green”, available at hardware stores and building supply stores, works well.

12. Keeping the pods upright screw all 4 pods into the subchassis. DO NOT TIGHTEN

THE PODS but rather screw them into the subchassis until the bottom of the pod

cap below the black 0-ring is approximately even with the bottom of the

subchassis. This is not a critical alignment, but just a starting point for further

adjustments.

13. Open the platter box. CAUTION: take care not to cut into the platter when opening

the package. If you use a knife to cut the tape, cut just deep enough to cut the

tape.

14. Note that the bottom of the platter has an arrow. Note that the bearing has a notch

in the rotating part that allowed you to insert the bearing mount screws. When

placing the platter on the bearing align the arrow and notch. This orientation

results in the most accurate rotating assembly, with the lowest possible wow and

flutter. CAUTION: WHEN PLACING THE PLATTER ON THE BEARING, IT

MUST BE SLOWLY LOWERED. ANY SHOCK OR IMPACT CAN RUIN THE

BEARING.

15. Open the motor box. Carefully lift the motor out, taking care not to allow any side

force to act on the pulley. ANY SIDE FORCE OR SHOCK ON THE PULLEY CAN

RUIN THE MOTOR BEARINGS.

16. After you have placed the turntable in its final location place the motor to the rear of

the subchassis, centered left-to-right on the centerline of the platter. Space the

motor away from the subchassis by the approximate width of the belt. NOTE: You

may place the motor to the left side of the turntable as an alternate location. In this

case, the motor is centered front to rear, and is spaced the same distance from the

subchassis edge, approximately one belt width.

17. To keep the soft vacuum hose from kinking you can use a cable tie to fasten the

motor cord, the ground wire, and the vacuum hose together at the connection

where the soft hose and gray hose meet.

18. Locate the belt. Loop the belt around the lower, smaller diameter surface of the

pulley and the platter. Guiding the belt at the pulley with one hand to be sure that it

does not jump off the pulley, slowly rotate the platter with your other hand to cause

the belt to find its natural position on the platter.

19. Mount the tonearm following the tonearm manufacturer’s instructions. If your

subchassis is cut for the SuperArm/Vector tonearm with the tall cup, the mounting

hole has a set-screw from the rear face of the subchassis, which locks the tonearm

at the desired VTA.

20. Level the turntable by turning one or more of the adjuster knobs at the corners in

the appropriate direction to raise or lower the corner in question. When turning the

knob to adjust level first lift the subchassis in that corner so that the pod is lifted off

of the turntable stand. Then turn the knob. This will allow the entire pod to turn

while you are turning the knob.

21. Adjust the feet on the motor so that the belt rides 1/8” or more above the bottom of

the platter when the belt is on the lower pulley surface (this surface is the 33 RPM

portion of the pulley.) This will prevent the belt from jumping off the platter if the

turntable is bounced while the platter is rotating. You may find that the pods must

be screwed further into the subchassis than the original position to achieve the

proper belt location on the platter.

Enclosed with your turntable are 12 rubber rings to place over the threads of any

motor feet you have partially unscrewed in your adjustments. You may stack as

many rings as necessary on the threads of the motor feet. Then you may lightly

tighten the feet, slightly compressing the rubber rings, so that the threads are

under tension, thus eliminating any free play or “wobble” between the feet and

motor.

22. To operate the 2800 at 45 RPM it is necessary to move the belt to the upper

portion of the pulley (unless you have the BASIS Synchro-Wave Power Supply,

please see additional instructions for the Synchro-Wave).

23. Connect the bearing ground wire to the ground on your preamplifier or to a true

ground. This wire drains static electricity from the platter/bearing assembly and is

not critical sonically except for performing this task.

24. Please see the additional instructions for the BASIS Vacuum System.

QUESTIONS AND ANSWERS CONCERNING

THE 2800 SIGNATURE SERIES TURNTABLE

Question:

“What are the sonic affects of raising or lowering the subchassis by turning all 4 pods a

certain number of turns?”

Answer:

There are none. This merely adjusts the height of the subchassis, which does not affect

the sound.

Question:

“There is a slight oily residue on the top lip of the spring cup part of the pod where the

threaded holes are. What should I do?”

Answer:

Merely wipe this residue off with a cloth or paper towel. This residue represents

damping fluid wicked to this surface during shipping and setup and represents an

insignificant amount of material, which will not affect the operation of the turntable.

Question:

“What type of turntable stand should I use?”

Answer:

We have not yet found a stand that makes a significant sonic difference. We suggest

using a stand that represents to you the best compromise regarding fit of the turntable,

aesthetics, and cost.

Question:

“Must I disassemble my 2800 to move it?”

Answer:

You should always remove the platter and tonearm when moving the turntable to

prevent damage to the bearing and cartridge. You do not need to remove the

suspension, but remember that the suspension fluid will spill if the turntable is tipped

more than approximately 10 degrees.
