I have a basic question regarding these. There are two types I see. One is an "all digital" that does not have a volume control knob at all but the volume is controlled up and down "digitally". The other has a motor driven potentiometer.

Are the contacts on the motorized pot version "dry"? In other words, is the pot hooked up to the rest of the circuitry on the supplied pcb or does the pcb circuit simply turn back and forth a pot that has no connections to it so that it may be directed connected to your circuit?

I'm hoping for the latter as I want a remote controlled pot to connect internally to a tube preamp circuit. In other words, connect this motor driven pot to the circuit exactly the same as a manually controlled pot.

yes. The kit includes also some relays to switch between different inputs, but they are placed on a different pcb than the pot. So you can use it as a simple "pure" motorized alps pot if you do not connect the relay board.

Hi guys
I bought on eBAY a "MV02 - 4 WAY REMOTE CONTROL" and can't make it work correctly. The seller can't help me so I hope somebody here can.

Motor works fine in 2 ways when +/- VOL or MON on remote is pushed down. Relays operate well with 1, 2, 3, 4, 5 buttons.

Problem : whatever 1, 2, 3, 4, or 5 button is activated, motor keeps turning endless counterclockwise until I push +/- VOL or MON. This also happens at power ON.

I tried all wiring combinations with CODE SWITCH (I don't knowwhat is the exact fonction of this switch) and even without it : same result.

There is 5.12V DC on AT89C51 20-40 pins, as expected. CODE SWITCH looks like a 3 pins rotary attenuator without stopping position.

I don't know how to solve this problem.
Thank's

Default functions

Hi,

as far as I know, there are some functions not controlled by any code switch, but by two resistors - R17 & R18. These instructions should be related to the MV-01.



Operation Mode of the Motorize Volume
R18 not install
Every time the Volume will turn to min. and the signal relay is turn on after a short delay of time after you turn on the power of the MV-01.
R18 installed
Cancel the function
R17 not install
Every time you change the Input Channel the volume will turn to min. and the signal relay is turn on after short delay.
R17 installed
Cancel the function

HTH

Ciao

Paolo

Default R17 - R18

on the schematic of the MV06:

R17 connected between pin 28 of U1 and pin 26 of U1;
R18 connected between pin 27 of U1 and pin 26 of U1


Ciao

Hi to you all!
I would like to ask something about the MV06: does it have 6 stereo channels inputs as claimed?
I am asking because i want to connect 6 sources (CD, radio, pickups, aux, etc.).
If it had 8 inputs, i wouldn't mind.....

Thanks

hey guys, im bumping up this old thread with an interesting qustion - could it be used to control an original motorized alps? meaning i will take out the pot from the circuit and just hook it up to the motor on a different alps pot - would that work?

it should work fine as long it has the same pinout. from what i ca remember the power for the motor only has two pins. the audio part of the pot has eight pins in one row and there are two rows. so if you pot has only 2 sets three pins in a row for audio. just use the power pins to power the motor and wire the audio direct to the pot. hope that help
