Last week I bought a second hand Panasonic AG-7500 SVHS Hi-Fi Video Cassette Recorder. It is a professional machine with many video and audio options. I feared it would be a huge quest to find a manual. I was delighted when I found owner-manuals.com. After payment I received the file to download the next day already. The quality is great. I am very happy. Thanks!
The owner's manual/operating instructions that I purchased was the original factory document and it was in at least three and maybe more languages. I no longer have it because I sold the tape recorder and included the owner's manual/operating instructions and a service/repair manual that I bought on ebay for the new owner.
Turns out this was not the manual i was looking for. The concertmate 670 keyboard i have is a "Realistic" model made for Radio Shack and none of the diagrams on the owners manual i received matches up. HOWEVER, I must say the service Owners Manual provides was fast and efficient by being available online. The manual was in good readable condition and easily downloaded.

Section 3. Using effects
Mid Level -80 � +6 (dB) Sets the volume level of the midrange after the signal passes through the compressor. Hi Level -80 � +6 (dB) Sets the volume level of the upper range after the signal passes through the compressor.
Input
This divides the original sound into three frequency ranges: low, mid, and high. Gain -24 � +12 (dB) Sets the overall volume level before the signal passes through the compressor. Delay Time 0�10 (ms) This sets the amount of time by which the source input sound is delayed. Split Freq L 20 � 800 (Hz) This sets the frequency (in the lower range) at which the source sound is split into three separate ranges. Split Freq H 1.6 � 16.0 (kHz) This sets the frequency (in the upper range) at which the source sound is split into three separate ranges.
Noise Suppressor
This effect reduces the noise and hum. Since it suppresses the noise in synchronization with the envelope of the sound (the way in which the sound decays over time), it has very little effect on the sound, and does not harm the natural character of the sound. On/Off on/off. Threshold OFF, ON This parameter turns the noise suppressor effect 0 � 100
Adjust this parameter as appropriate for the volume of the noise. If the noise level is high, a higher setting is appropriate. If the noise level is low, a lower setting is appropriate. Adjust this value until the decay of the sound is as natural as possible.
* High settings for the Threshold parameter may result in there being no sound when you play with your instruments volume turned down.
Limiter
This suppresses high-level signals to prevent distortion. On/Off Sets the limiter to ON or OFF. Thres OFF, ON -24 � 0 (dB)
Adjust this as appropriate for the input signal from your bass. Attack 0 � 100 (ms) This sets the time it takes for the limiter to go into effect once the input level exceeds the threshold level. Release 50 � 5000 (ms) Adjusts the time until when the limiter will turn off after the input level falls below the threshold level.
Release 0 � 100 Adjusts the time from when the noise suppressor begins to function until volume reaches �0.�
Output
This makes settings that affect the overall output. Level -80 � +6 (dB) Sets the volume level of the overall sound after the signal passes through the limiter.
Section 3
Mixer
Adjusts the volume of each frequency band. Lo Level -80 � +6 (dB) Sets the volume level of the lower range after the signal passes through the compressor.
Phaser
By adding varied-phase portions to the direct sound, the phaser effect gives a whooshing, swirling character to the sound.
* This effect can be used when the FX �Type� parameter is set to �PHASER.�
