• Natural negative feedback - The A-5000 DHT applies about -6dB of negative feedback. This is a very complimentary amount of negative feedback that differentiates the Allnic 300B single ended amplifiers from the standard, which have a very coloured and weak speaker driving force. -

Page 6: Cleaning
INITIAL SET-UP LOCATION, LOCATION, LOCATION Like all audio products using tubes, the Allnic Audio A-5000 DHTs need to be placed on a solid stand in a location that provides good air circulation around, above and below the monoblocks. • DO NOT cover the tops of the A-5000 DHTs. -
Page 7: Inputs
Each A-5000 DHT is equipped with one pair of high-quality speaker terminals (See Figure 4). These terminals are located in the middle of the rear panel of the A-5000 DHT chassis, with the red marked terminal for the live connection labelled positive “+” on the right, and with the return connection labeled negative “-”, to the left (facing the chassis rear). -
Page 8: Operation
The illuminated meter on the front of the chassis (see Figure 5) indicates the current supply to the 300B tube in the A-5000 DHT. There is a potentiometer that is used to bias the 300B (Refer to Figure 6 for its location). - Page 9 If the meter’s needle drops to the left limit of the meter’s face during operation and audio output stops, this indicates a failure of the 300B tube. The fuse will have “blown” as well. You must turn off the A-5000 DHT and replace both the fuse (315mA @ 250V, 20mm glass, fast blow type) for the tube and the 300B.
