Krell KSA300S set up

[corbelli]

Recently I have bought a Krell KSA300S with a new (changed in service) board control

I need to Know the function of control panel swiches on Krell KSA300S. I have a remote with no function. I suspect this new board need any procedure for the correct use of remote.

Do you have any procedure for syncronice the remote with the control panel?

¿Any Schematics or explanation ?

Switches in panel and remote pictures atacched. Excuse my painfull english.

The first picture isn´t mine. My new control board is the same but in red colour. (I don´t have opened the amp for the picture)

Thanks in advance. Daniel.

I have tested the remote with a infrared remote tester and it´s emiting correct signal.

I´m sure that it have any procedure for syncronize the remote and control board, but I don´t Know

I put my control board picture. The red micro-switch in the upper right of thepicture is for power up option (manual or mains) and the other micro-switchs have an incription:"unit select" , I supposse for master-slave amps control.

Please any idea for sincronize the remote with control board??

HELP!!

I send a mail to Krell service with my problem and they send me this one:

Dear Daniel,
The red faceplate board indicates that the unit is dedicated for 240v operation only.
I would recommend that you remove the AC power for approximately 3 minutes, and reinstall to reset the remote operation.

If this fails to correct the issue. You will need to be in contact with the authorized Krell service center that originally performed the repair. And we will deal directly with them to resolve the issue.

I have reinstallled to reset remote operation but nothing, same problem.

This baby have a 200lbs weight and I don´t like to send newly to technical service in Valencia (Spain-Europe).(1200 Kilometers travel) to pay a bill in shipping cost for a simply procedure to marry board and remote.

Have you any similar problem? Have you any idea?
Something have the service manual of this Krell or similar KSA-S Series?

I might ask for the obvious but are the batteries still in good shape?
If they are, as the Krell mail indicates, this will be a software issue that you probably can't fix yourself.
Either live with it or send the unit in.

Nice amp.

Hi,
is the amplifier powering up anywhere?

Have you read the threads on Krell's grey import defeat circuit?

Could the chip (if you have one ) be detecting the wrong combination of mains voltage and frequency and shutting down because the amp has crossed a border from the importer?

[corbelli]

The amp power up normaly with power switch on amp faceplate.

The remote no function and yes have new batterys.

The amp is for 220 operation. The new board control is for 240 operation. The amp works perfectly except the remote.

[corbelli]

The chip in board control is a Motorola MC68HC705P9 with KSA v3.1 software programation.

The amp is from Spain original Importer "Sarte Audio Elite"

Have you read the threads on Krell's grey import defeat circuit?

I don´t understand very well this. Can you explain me?

Thanks for help me.

Hi,
if the amp is powering up and works manually then grey import is not the problem. Just the remote problem as you described.

Krell have a chip inside their newer models that compares the mains voltage and the mains frequency to a database to ensure the country of official importation matches the current mains supply. If it has moved to a location that does not match, it refuses to start up and the unit has to be returned to an official Krell dealer to be rechipped and the charge includes the lost profit from the grey import. The markup in the European distribution network is enormous.

OK..

The remote should have any proccedure to link with control board.

Surely press the power button in both during one time, or press in faceplate power and display button in adittion to one button in remote or....


Have somebody any experience on this or similar Krell remotes?

Have somebody any KSA, MDA or FPB service manual for remote operation item?
