SPEED DEPENDENT VOLUME CONTROL (MIDLINE SYSTEM AND BOSE SYSTEM)

If activated, the radio output volume will be automatically adjusted to compensate for increased driving noises

at higher driving speeds.
The radio receives a vehicle speed signal from the combination meter, and selects the output volume.

break audio line. J2 input goes to mic pin J1output to radio.
(leave the shielded ground wires disconnected. on audio)
Power use a 1k ohm resistor from 12v dc on pwr switch.
Ground run the ground wire to board ground
test and set echo level.
this will work for any radio. if the echo needs 12v instead of 8v remove the 1k resistor and just use a 1n4001 diode on the power wires . some models require 12v some are 5-8volts.

If I remember right those mics were for relay switching radios and not transistor switching radios like todays models. Also I would bet you would be very disappointed with the results as the ranger radios have an excellent modulation circuit that does not need any help from a power mic. A trustworthy radio shop tech can tune up a Ranger and make it sound excellent without a power mic. I haven't installed one in years. They are a waste of money and time in most cases except for the D104 which can be used with some base stations.

Sounds like something was shorted out while replacing your ignition or you damaged a ground wire. You can try connecting just the 12+vdc switched lead to 12+vdc power and then ground the receiver to a chassis ground somewhere else to see if it is just a grounding issue. The yellow lead (memory) will also need to be connected in higher end units such as Alpine as the audio amp pulls from the memory lead rather than switched lead.

Gday mate,geoff here, now with the speakers ( Green plug) and the microphone ( Pink Plug) there should be on the back of the macine 3 small sockets Blue, green and pink, the blue for auxilary input, alternitively there is a small hatch on the front with these plugs in there, hope this helps, geoff.

Hi elli178...
Redownload and install your audio drivers for windows 7, after installation your audio should be back to normal.
I could not get your driver for you because you did not give the complete model number of your Toshiba l300...
But you can download the driver by doing the following:
Go to the following webpage and put your computer information into the boxes and download your FREE audio driver...
Please take time to rate me

Most micraphones are mono, set the recording channel to mono.

control panel admistrive tools,computer management,device manager scroll down sound and video controllers you should see a yellow question mark? right click to reinstall drivers you might find something there hope this helps

you ony need the green for audio.. the other is for the micraphone..

It is possible that the ground wire for the audio unit is connected the dash illumination wire that lit up the orginal audio unit. It is a ground when the lights are off when checking for a ground but when the lights are turned on it has power on it causing the audio unit not to operate.

I would run a seperate wire for the ground to make sure the audio unit gets a good ground.
