![]() ![]() About 2 minutes after all input signals are removed, the amplifier automatically shuts down and returns to its stand-by mode. If the small auto-on slide switch on the rear apron is set to on and the red power lamp is lit, the amplifier will turn on automatically within 1.5 seconds after a signal reaches its input connectors, lighting the green LED. The green LED (marked ACTIVE) indicates that the amplifier is switched on and operating.Ī somewhat unusual (and useful) feature of the 260x3 is its Auto-On mode. ON) shows that the amplifier is plugged into a live outlet but not necessarily that it is turned on. In addition to the pushbutton power switch, the front panel has three speaker-selector buttons, two status-indicator lights, and individual channel-level controls that can be adjusted with a screwdriver through small holes in the panel. The Sonamp 260x3, finished in black, measures a compact 16-3/4 inches wide, 12-1/2 inches deep, and 3-1/2 inches high. The AC-line fuse on the rear apron is readily accessible to the user. Several protection circuits and a relay safeguard the amplifier against overload, overheating, or output short circuits. The power supply uses a heavy toroidal transformer with 30,000 microfarads (μF) of filter capacitance. Its discrete output transistors are mounted on heat sinks, convection-cooled by air entering holes in the bottom plate and exiting through holes in the top cover. The Sonamp 260x3 is designed to drive 2-ohm loads without overheating or distortion (three paralleled 8-ohm speakers represent a load of 2.7 ohms). And the stereo line-input jacks on the rear apron are paralleled with a second pair for linking (“daisy-chaining”) additional amplifiers. For convenience in operating multizone systems, the 260x3 has pushbuttons on its front panel for individual activation of its three pairs of speaker outputs. It is designed to drive difficult loads, particularly the low impedances presented by multiple parallel-connected remote speakers. The Sonamp 260x3 is a high-cur-rent, 60-watt-per-channel stereo amplifier with a number of features that make it well suited for custom installations. The amplifiers are marketed under the name Sonamp. Thoughts? Comments? Anything will help, including opinions on the Sonos VP speakers.Sonance, one of the pioneers of in-wall loudspeakers for multiroom installations, also manufactures amplifiers specifically designed for the requirements of such installations but (like the speakers) not limited to those applications. A separate amp will run the Sonos VPSUB (or pair of VPSUB’s). I’m thinking the best setup is to bridge one pair for 100W RO the center channel (Sonos Reference R1), then the other 10 channels run the other 10 speakers. (2) If I don’t use all 12 channels on the Sonamp, will the amp be able to use all 600W over fewer channels? I think I could bridge each L/R pair and have 100W over 6 channels, but what if I used 7 channels, would the amp be able to do 85.7W per channel, or is each channel individually amplified? (1) If the speakers (a mix of Sonance VP48 Rectangles, VP46 Rectangles, VP46R for height) are rated at 5W min and 100W max, is 50W from the Sonamp a good power rating to run the speakers? If the speaker (R1 for the center channel) is rated 5W min to 150W max, can the Sonamp power it efficiently? I’m building a 7.2.4 Atmos system and will get a separate amp for the sub(s), but for the non-sub speakers I’m curious about 2 things. Hi everyone, I’m debating getting an 11-Channel AVR (built-in amp) or getting a pre-pro with pre-amp outs and using a Sonance Sonamp 12-50 to power each speaker. ![]()
