400M Power Amplifier Rear Panel Layout Figure 1: Rear panel of Nēo 400M Mono Power Amplifier The rear panel will look similar to Figure 1 (above). Each channel has one balanced (differential) input on an XLR connector and one unbalanced (singleended) input on a RCA connector. There is no switch to toggle from balanced mode to singleended mode. You may operate the amplifier in either mode, but only one mode at one time.
400M Power Amplifier Connecting the 400M Prior to making any connections or removing the XLR jumpers, the power amplifier must be turned off and the AC cable disconnected for at least 1 minute. 1. Connect the input cables running from your preamplifier’s outputs, whether balanced or single-ended, to the amplifier’ s XLR or RCA input, respectively.
400M Power Amplifier Operating the 400M We recommend leaving your Nēo 400M powered up at all times to maintain optimal performance. When you plan on being away for a few days, it may not be a bad idea to power off your amplifier. Please keep in mind that once fully “broken-in”, your 400M requires several hours of operation before reaching optimal performance after powering it up again.
400M Power Amplifier Remote Operation Figure 3: Remote Operation In figure 3 we have a Nēo 350P Preamplifier and a pair of 400M Amplifiers connected together via their respective 12V triggers; The 12V trigger output on the 350P is connected to the 12V trigger input on the top 400M (using a 1/8” mini-jack cable). The 12V trigger output from this 400M connects to the 12V trigger input on the bottom 400M (also using a 1/8” mini-jack cable).
