Heres some pics of my XM-2040 from 1991.
Its missing some wires on the molex connector plug. Anyone have a spare connector plug ? https://www.caraudioforumz.com/attac...ine=1360961810 https://www.caraudioforumz.com/attac...ine=1360961810 https://www.caraudioforumz.com/attac...ine=1360961810 https://www.caraudioforumz.com/attac...ine=1360961810 https://www.caraudioforumz.com/attac...ine=1360961810 https://www.caraudioforumz.com/attac...ine=1360961810 https://www.caraudioforumz.com/attac...ine=1360961810 |

Here's my latest NOS (new old stock) amp.
Early 1980's Concord HPA-26 50 watter :) Very tiny amplifier, around the size of my hand. https://www.caraudioforumz.com/attac...ine=1394122293 https://www.caraudioforumz.com/attac...ine=1394122293 https://www.caraudioforumz.com/attac...ine=1394122293 https://www.caraudioforumz.com/attac...ine=1394122293 https://www.caraudioforumz.com/attac...ine=1394122293 https://www.caraudioforumz.com/attac...ine=1394122293 https://www.caraudioforumz.com/attac...ine=1394122293 |
Wow - look at that input impedance. yikes! :eek:

Heres what I read: Input Impedance: The input impedance is the impedance (that the signal source 'sees') from the center conductor to the shield on an unbalanced input circuit. A typical input impedance would be ~10,000 ohms but some amplifiers may have an input impedance of more than 50,000. If the input circuit uses a mini DIN type connector, the input impedance could be measured from one signal terminal to the other or from the signal terminals to the shield ground. Ideally, the impedance should remain constant throughout the audio band. More than a few amplifiers employ some sort of high frequency noise filter which will cause the input impedance to fall slightly at the upper end of the audio spectrum. These filters are designed to reject high frequency noise from the amplifier's switching power supply. It should also remain constant regardless of the position of the gain control. Some amplifiers (especially budget amplifiers) will have varying input impedance when the position of the gain control is changed. Head units (or equalizers, crossovers...) with low output impedance will handle these variations better than standard head units. Generally, a head unit with high output impedance will have reduced high frequency response if the amplifier's input impedance isn't consistent across the audio spectrum. |
