STEREO POWER AMPLIFIER M-700u 1 Precautions Installation place Install this unit in a location where good ventilation and heat radiation is assured. Especially, placing this unit where direct sunlight is present, where the temperature rises excessively high such as close to a heater, or where it is humid or dusty may cause a malfunc- tion even if heat is efficiently released. Ventilation holes Do not block the ventilation holes of the top and bottom pan- els. If the amplifier is installed on a rack or the like, secure ample space for cooling and leave the door open. Do not pile up other things on the amplifier and never put articles on it. Failure to observe this may cause a malfunction. Note: For heat dispersal, do not install this equipment in a confined space such as a book case or similar unit. Precautions in connecting with other components When connecting this product with a control amplifier and such, be sure to turn off the power of this product and all oth- er connected devices. Failure to observe this may generate a strong noise resulting in speaker damage or a malfunction. The pin-plug to be inserted in each input terminal of this unit shall be pushed in firmly. If the grounding terminal is inade- quately connected, noises including hum may be generated, resulting in an adverse S/N ratio. Cautions in connecting speakers When making speaker system connections, exercise extra care not to short-circuit between /œ and /š of the speaker terminals and speaker input terminals of this unit. If a large signal is applied to the amplifier with its circuit left short-circuited, a large current may be passed through the output circuit and cause a malfunction. The sound is not generated shortly after the power supply is turned on. This amplifier is equipped with a time muting circuit in order to separate the output circuit. Therefore, no sound is generated shortly after the power supply is turned on. If the volume control is moved to a high sound level before the time muting circuit is canceled, a large sound is suddenly generated. Please be advised that the volume control of the input device such as a control amplifier shall be set to a low level at first and adjusted according to your taste after sound comes out of the speakers. Protection circuit This product is equipped with a protection circuit that is ac- tivated upon detection of overcurrent, abnormally high tem- perature, and DC drift to protect the amplifier and speakers. When the protection circuit is activated, the output to the speaker terminal is shut off and the standby indicator lights up to show that this product is in the standby state. Please consult your dealer when the protection circuit is sometimes activated even after turning off the switch, disconnecting the power plug from the wall outlet, and connecting it again after a while. Repair and adjustment When repair and adjustments are needed, please ask the dealer where you bought the unit. Cleaning For cleaning, use a piece of soft cloth to wipe the unit such as cleaning cloth. When the dirt is hard to remove, use a small amount of neutral detergent to wipe, and then wipe the unit with dry cloth. Do not use a solvent like benzine or thinner because such a substance can often damage the exterior. * Note Wall * * * Exercise extra care when this unit is unpacked, assembled, transported, and installed because this unit is heavy.
