A 2 x 50 watt hi-fi stereo Power Amplifier. With a high-voltage, high-current output stage enabling it to deliver well above its rated power to handle musical transients, and a 'soft clipping' circuit which gently limits the waveform voltage when the amplifier is driven beyond its rated power.
On the rear, Main-In sockets for connection to a pre-amplifier, connectors for two pairs of loudspeakers, switches for Soft Clipping (On/Off), Bridging (On/Off) and a Speakers Impedance switch (Normal/Hi (≥ 8Ω)), the Hi setting can be used where one pair of speakers are connected and their impedance is at least 8Ω, this re-optimizes the amplifier for maximum power. Some models have a switched and an unswitched AC outlet and some a voltage selector.
On the front, switches for Power, Speakers A, B, LED indicators for Power, Protection and Soft Clipping and a jack for headphones.
