pedance is less than 8 ohms, the SE-240 can deliver more power into the lower impedance.
Sound reproduction accuracy is largely a measure of your success in satisfying an illusion of the original. There are few rules for speaker placement. The shape, furnishing and acoustics of the room contribute as much as speaker choice to the overall balance which you will find most satisfying. In general, the two speakers are best placed equally distant from the listener and from each other, either along or just in front of a wall. It is best to have no obstructions between the speaker and the listener. Some- times raising the speakers is beneficial. Sound absorbing materials, such as carpeting, draperies and upholstered furniture help to reduce reflections, and thus improve the sound illusion, but excessive absorption will deaden the effect. Feel free to experiment with controls and furnishing to achieve the overall balance which you like.
OPERATION
The pilot lamp in the power switch will glow whenever power is applied in the SE-240. If it does not light, check for a blown AC line fuse.
The SE-240 is equipped with a unique protection system that constantly monitors the temperature of the output devices and takes corrective action to prevent damage to the amplifier as a result of excessive overheating. Under most conditions, the SE-2403 heatsinks will dissipate the heat required to maintain safe operating temperatures, and the unit will play continuously. If the amplifier is driven at high volumes into speakers with an impedance of less than 8 ohms, and/or there is inadequate ventilation, the heat- sinks could heat to a level that would cause the protection circuitry to shut the unit off for a short time (normally less than 1 minute) to prevent damage. The SE-240 will return to normal operation, and if the overheating condition is still present the cycle will repeat. In this case, check the surroundings of the unit to ensure sufficient air flow around the heatsinks and through the vent holes. Otherwise, check the load impedance connected to the outputs to see if it is far below 8 ohms.
