The response in both modes is very similar, and shows a modest downshelving in the high frequencies that may slightly soften, but not dull, the treble. The output impedance measured 524 ohms in the left channel, 538 ohms in the right.ДЇig.1 shows the frequency response of the 834P, with the MM result displaced up by 1dB. The input impedances for the MC setting were 515 ohms and 516 ohms (L&R). Set to MM, the 834P's input impedance was 49.7k ohms in the left channel, 51k ohms in the right. The corresponding results for the MC configuration were 62dB, 60dB, and 72.2dB, respectively (left channel). 1V output) for the MM setting was 65dB from 22Hz to 22kHz, 61dB from 10Hz to 500kHz (both unweighted), and 74.6dB A-weighted (results are for the right channel, which was noisier). I don't anticipate this high gain to cause any problems, but I'd check to make sure that it won't overload my line preamp. These are very high values, particularly for the MM typically, the gain in MM gain stages is 35вЂ“40dB, and 55вЂ“65dB in MCs. The EAR's voltage gain measured 49.2dB moving-magnet, 68.2dB moving-coil. The measurements below were taken on this latest version. There appear to be some minor changes in parts-particularly regarding the power supply electrolytics-but no radical alterations in the original circuit or its layout. The interior layout was nearly identical, though the main circuit board (screen-printed with a '1996' copyright date as opposed to BJR's sample's '1995') was somewhat larger (with a larger case to accommodate it).

It was slightly different from the original unit: The front-panel level control had been deleted, and the front panel itself was far better finished. EAR sent us a second, more recent sample. Since he'd clearly had no problem with it, we can only assume that it was damaged in shipment. The EAR 834P we received from Bob Reina arrived defective (it had extremely low gain).
