Note:

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. It is designed to drive difficult loads, particularly the low impedances presented by multiple parallel-connected remote speakers. For convenience in operating multizone systems, the 260x3 has pushbuttons on its front panel for individual activation of its three pairs of speaker outputs. And the stereo line-input jacks on the rear apron are paralleled with a second pair for linking (“daisy-chaining”) additional amplifiers.

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). 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 power supply uses a heavy toroidal transformer with 30,000 microfarads (μF) of filter capacitance. Several protection circuits and a relay safeguard the amplifier against overload, overheating, or output short circuits. The AC-line fuse on the rear apron is readily accessible to the user.

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. It weighs about 16-3/4 pounds. 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.

A somewhat unusual (and useful) feature of the 260x3 is its Auto-On 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. About 2 minutes after all input signals are removed, the amplifier automatically shuts down and returns to its stand-by mode.

The Sonamp 260x3 is rated for outputs of 60, 100, and 125 watts per channel into 8, 4, and 2 ohms, respectively, from 20 to 20,000 Hz at respective distortion levels of 0.05, 0.1, and 0.2 percent. The respective dynamic powers into those impedances are given as 85, 120, and 140 watts per channel. A-weighted signal-to-noise ratio (S/N) is 100 dB referred to rated output. Input sensitivity for rated output is 0.625 volt at maximum gain.
