How do I calibrate elevation grade for treadmill?


Hey there, sorry to hear you're having an issue with your elevation motor. I would be happy to help you solve the problem.
Since you already installed your motor you can go straight into diagnostic mode.

To get into Diagnostic Mode on your L8
Make sure to turn off your treadmill.

-ET's - Press Menu and Start at the same time
-CT's - Press Manual (or Display^) and Start at the same time
-All other L SERIES mills - Press Display (or display and Start at the same time

SideNote-
-*CT's that were manufactured after 09/2003 - Press Display and start at the same time.




Few things you want to do, if you haven't already.

A. Align the motor with the clevis mount and install the motor mounting pin.

B. Insert hitch pin.

C. Reconnect the elevation harness to the lower board

D. Set the lowest limit switch by holding the UP elevation button for 5 seconds. Then press and hold the DN elevation button one more time to make sure you only hear a click.

E. For L7/L8 machines; Thread the elevation nut to where its flush with the threads on the "worm' shaft.

F. Mount the elevation nut to the leg assembly by lining up the holes on the leg assembly. You may have to move the leg assembly so that the holes on the elevation nut line up. Then slide the two elevation pins through the elevation assembly and into the elevation nut. then secure the pins with the 2 set screws.




To calibrate your potentiometer you can try to adjust while it is installed but for best results you must calibrate it before its in your motor housing.







G. Calibrate the elevation potentiometer and to do so you must;
1st: Visually confirm treadmill is leveled. (0% grade)
2nd: Adjust the settings as follows;
All L SERIES millls should read 0.0
3rd: If the setting is incorrect, follow these steps.
Step 1: Turn the post of the potentiometer all the way
CLOCKWISE.
Step 2: SLOWLY turn the potentiometer COUNTER
CLOCKWISE until the setting is correct.

H. Carefully install potentiometer into the motor housing
*NOTE: The setting may vary when inserting the potentiometer
into the motor. As long as the change is minimal, fine
adjustment can be achieved by rotating the meter
while inside the elevation motor.

I. Press OFF to turn treadmill off. Then restart the machine in manual mode to TEST elevation after resetting your potentiometer. As long as the change is minimal, fine adjustment can be achieved by rotating the potentiometer while inside the elevation motor.


For more Diagnostic features and possibly further detail, I will be attaching a Link to your machines service manual. I hope this helps, always hear to help. SportSmith.

How do you adjust the tone arm on a Denon DP-47F turntable? Thanks Cosmicharlie


Basically, like almost any other turntable.

Look up the recommended tracking force for your cartridge/stylus.

Unplug the power to the turntable.
Using the tonearm elevation control, raise the tonearm.
Manually move the tonearm in toward the platter.
Manually rotate the platter ClockWise a few turns to disengage any cueing mechanisms.
Set the Tracking and Anti-skating controls to 0.
Disengage the tonearm elevation control. The tonearm will either float or drop. This is why we have no power, just in case it hits the platter.
Adjust the counterweight until the tonearm floats exactly horizontal. Use the flat portion of the tonarm rest as a gauge.
Return the tonearm to its rest.
Dial in the prescribed tracking force and anti-skating. Play records.

How to set the the bluetube dp


Setting of the DP2 depends on what type of input signal used. If the input is a strong line level,source such as the output of a keyboard or a synth module you may want to engage the Pad button and then set the gain knob to bring the average signal to 0 on the VU meter.
If you are using a condenser microphone the 48v button must be engaged and again set the gain control for an average of 0 on the VU meter.
If using a dynamic microphone, the 48v button does not need to be engaged,but it doesn't matter if it is on.
When using inputs plugged into XLR the signal can be inverted by depressing the I/O button, this will reverse the signal phase going to your multitrack (used for signal phase problems)
The 80hz button can be used to minimize annoying low frequencies (A/C rumble)present in the signal.
The tube drive knob is used to direct the signal to a 12ax7 tube drive circuit in conjunction with the main gain knob and as usual you want to keep the signal close to 0.
The clip light should not be illuminated when a signal is present,slight flickering is ok but total illumination means the signal is distorting.
This is a two channel unit so chn 2 is an exact copy of chn 1 and all controls are the same.
Most important, use your ears and listen closely to the results.

Ultra Linear UL600HC gain pot broken off of board


No, open the system, check the switch in questions, get a soldering iron and desolderer to remove the switch, do it carefully, when you have the switch in your hand go to maplins or somewhere like it, find an exact replacement(wont be hard to do) and get someone confident with a soldering iron to solder it back in.

Total elevation gain consistently way too high (20+ percent)


I have the same garmin, and have the same problem.
The high changes even during flat runs so when added you have this overamount of climbing.
I just reduce the points of the track and then the addition is more accurate.
My problem now is that the GPS stops working during runs (turns itself off). Awful!!!

Which is a better tuning setup for good quality bass ?


The KAC-8401 has a bass boost switch. Be sure that is on +6dB setting.
Secondly, LPF (low pass filter) should be selected, with the crossover cutoff set to 60Hz.


Follow the instructions on this site for accurate tuning....

There is so much bad information and VOODOO going around the internet about how to set car audio amplifier gain controls that I thought I better write this. Gain controls on an amplifier are basically just small potentiometers (variable resistors) or volume controls if you will, that allow you to adjust the incoming signal to the amplifier so the amplifier works well with your headunit of choice or to match the level of other amplifiers in your system.
Its not rocket science to set the gains. Gains are like little volume controls, (I don't know why so many installers are taught that gains are NOT volume controls, when in fact that is EXACTLY what they are!) its super simple to just set them where the level sounds good to you.
With one amplifier its desirable to have a nice swing on your headunits volume control. Let me try to clarify this a little.
If we hook up a head unit with a 8volt (or more) output to an amplifier, then the volume will get loud very fast when we start to turn it up...In other words if our digital volume control goes from 1-30, then a HIGH VOLT output to an amplifier might make the amplifier reach full power at 5 on the volume scale... That kinda sucks cause it would be nice if you had a little more swing in your 1-30 range!
And by the same token a headunit with a LOW VOLT output might have to be turned up all the way to 30 and might still not quite drive the amplifier to full power... That sucks too!
A gain control in this case will allow you to adjust the amplifier so it allows the volume of a headunit to control the amplifier so it will get loud at a desirable point in the 1-30 swing... Usually about 3/4 the way up. We don't want it to get loud too fast as we wont have a good control as music levels differ. And we don't want it to have to be turned up all the way to get loud either, because since different music may be recorded at different levels if we set the gains for max output with one music source it might not get loud with a music source recorded at a lesser level.
So, by setting the gains so 3/4 turn of the headunits volume knob gets it LOUD gives you plenty of control and some extra above the 3/4 mark in case you get some music that's recorded at a lesser level...
To do this its easiest to do it by ear. No need to drag out the TEST TONES and OSCILLOSCOPES! They will do you absolutely no good.
One MYTH is how the gain controls will help to prevent amplifier distortion and amplifier clipping... That's simply not true, UNLESS you set the gains at a level where the headunit cannot possibly drive the amplifier to full power.. And even if you were to find this magic spot for your gain controls then (A) you would have to turn that volume control FULL SWING to get your system loud and (B) since many music sources (or disks) are not all recorded at the same level, its likely that if you have a disk recorded lower then you cant get it loud at all! and if you have a disk recorded louder then you can still surpass your magic spot... So in reality searching for this magic spot is fruitless! Dont waste your time...
In the early 80s when high fidelity car amplifiers were just starting to make the scene I worked with a pretty crazy installer that was kind of legendary around these parts... I wont mention his name but he was pretty highly respected at the time.. Well anyway, this crazy installer had heard that the amplifier gain control was to prevent amplifier clipping.. (still widely heard today).. Well this crazy installer set up EVERY CAR WE DID to the point where the gain control was so LOW that if you turned the head unit all the way up the amplifier WOULD NOT DISTORT.. And of course if you did turn the headunit all the way up the system would just be getting loud...
Customers would find that some cassettes would be recorded at a lower level and the music just wouldn't get loud enough... The Crazy installer would FLIP OUT and tell the customer that a REAL AUDIOPHILE doesn't want his music to distort or be that loud! The customers were NOT HAPPY and came to me to say "Gee Eddie, I don't want to make the other guy mad but can you adjust my system so it sounds good and please dont tell the other guy? Of course I said yes, and some of those customers from back in the early 80s are still my customers and they are sending sending their children to me for work as well.
SO, you see the only way the gains can be used to eliminate clipping or distortion will also limit your top end volume! And for most of us it is NOT DESIRABLE to do so.
As long as this is not done, it is just as possible to turn your system up to FULL power and beyond to clipping no matter where the gains are set....

Hello Shaun123, Phase adjust the amount of lag or lead one signal has in reference to another. Frequency is an adjustment of the number of cycles pers second a signal will produce. Gain refers to the amplification factor of a signal. now in reference to you amplifier by changing phase you can set the delay of a signal (if used right you can make a wicked reverb effect), but setting phase normally will affect the tones Frequency will affect for bass and treble functionality Gain will both preset and provide amplitude adjustment (volume) Take into mind these are more then likely presets. I hope this helps
