An excellent example of the Pioneer SG-9800 Graphic Equalizer in a Pioneer wood case. All sliders cleaned with Deoxit F100L Fader Lube, tested & working great. This unit makes a huge difference with digital music like CDs and MP3s. Description The Pioneer SG-9800 is a 2 channel, stereo, 12 element graphic equalizer with tape monitor. The graphic equalizer divides the audio frequency spectrum into 12 segments from 16Hz to 32 kHz, with each segment corresponding to an octave. Individual controls for each segment provide continuous adjustment (from -10dB to +10dB) and allow the sound to be contoured in order to compensate for equipment and speaker characteristics, listening room acoustics or personal preferences. Adjustments can also be performed during recording. Specifications Output Level: 1V (7.5V max) Gain: ± 0dB Frequency response: 5Hz to 100kHz Signal to Noise Ratio: 92dB Total harmonic distortion: 0.02% Control Range: ± 10dB Frequency Bands: 16, 32, 64, 125, 250, 500, 1K, 2K, 4K, 8K, 16K, 32KHz Semiconductors: 27 x IC, 2 x FET, 14 x transistors, 19 x diodes Dimensions: 420 x 150 x 355mm Weight: 7.1kg Year: 1980 ALL ITEMS ARE DESCRIBED AS BEST AS POSSIBLE AND DUE TO THE NATURE OF USED ITEMS ALL SALES ARE FINAL. I am very honest about any issues that exist, just check my feedback. One buyer reviewed me as “Honest, Honest, Honest Seller”. The one recent bad feedback was left by a scammer. I treat buyers like I would expect to be treated. I am a hobbyist that buys items that need help, clean/fix them up, enjoy them for a while and sometimes sell them. I do not work on other peoples equipment. If you need someone to service your equipment, I recommend Just Audio in White Marsh, MD. If you need help hooking up anything you buy from me, just message me and I would be more than happy to assist. Check out the photos. The photos display exactly what this item is. I would like to guarantee this item. However, too many unprincipled buyers that strip parts and then wanted to return electronics as being defective force me to protect myself from this type of abuse. I will pack well and insure the package during shipping. One recent buyer stated that he thought that his unit could have been dropped from a truck at highway speed and still survived intact. Shipping damage has not been an issue for any of my items for many years because of the care I take packing. If the shipping cost seems excessive, eBay seems to overestimate shipping costs so I have been offering to refund anything over the actual shipping cost. I tell them the size and weight and they estimate from there. · Nothing else, no further warranties or guarantees are implied. This vintage item is being listed and sold AS-IS because of parts swappers, people hooking stuff up wrong and scammers. · I video record the unit working, as well as the process of both packing and shipping so that there is concrete evidence that the item I sent is what was listed. I will also have video recordings of returns being opened. I will not only take this evidence to eBay but I will take legal action as Mail Fraud is a Federal offense.
