Mark Levinson No.326S
Beschrijving / Description
Last version!
The No.326S has three pairs of balanced inputs on XLRs and four single-ended inputs on RCAs. Signals passed through the latter are internally converted to balanced operation before being fed to the two volume-control daughterboards (one for each channel), these also made of Arlon 25. Precision surface-mount resistors, controlled by a front-panel shaft encoder, are used to provide 1dB steps for the bottom 23dB of the volume control's 80dB range, and 0.1dB steps for the top 57dB. The volume control can be bypassed for each input for home-theater use, and the maximum gain for each input can be set from 0dB to 18dB, in three 6dB steps.
The left- and right-channel audio circuits are physically separated, and there are balanced and an unbalanced output jacks at each end of the rear panel. The input jacks are mirror-imaged (ie, input 1 is on the outside and input 7 on the inside
for each channel), and in the center of the rear panel are the control, communication, and tape output jacks and a ground terminal. If the optional phono boards are installed, these take the place of the single-ended line input 7.
Overall, the No.326S's quality of construction is superb, as you'd expect from a preamp of this heritage and price.
