5. Configuració

5.1 Vacuum Tube Installation

  1. Carefully unpack the vacuum tubes from their protective packaging.
  2. Identify the correct sockets for each tube (one 6N1 tube and two 6L6 tubes). The sockets are designed for specific tube types.
  3. Align the pins of each vacuum tube with the corresponding holes in the socket. Note that the pins are keyed, meaning they will only fit in one orientation. Do not force the tubes.
  4. Gently push each tube firmly into its socket until it is fully seated. Ensure there is no poor contact.

Precaució: Incorrect tube insertion can damage the amplifier or prevent sound output. Always ensure tubes are correctly oriented and fully inserted.

5.2 Connexió de fonts d'àudio

The Nobsound F5 has two stereo RCA inputs (CD and AUX).

  1. Connect your audio source (e.g., CD player, smartphone, computer) to either the "CD" or "AUX" RCA input jacks on the rear panel using appropriate RCA cables.
  2. Ensure the left and right channels are connected correctly (red for right, white for left).

5.3 Connectar altaveus

Connect your passive speakers to the speaker output terminals on the rear panel.

  1. Identify the impedance of your speakers (typically 4Ω or 8Ω).
  2. Connect the positive (+) terminal of your left speaker to the corresponding 8Ω or 4Ω terminal for the left channel (L) on the ampmés viu.
  3. Connect the negative (-) terminal of your left speaker to the 0Ω (common ground) terminal for the left channel (L).
  4. Repeat the process for the right speaker (R) using the right channel terminals.
  5. Ensure all speaker wire connections are secure and there are no stray strands that could cause a short circuit.

5.4 Connexió d'alimentació

  1. Connect the included power cord to the AC power input on the rear panel of the ampmés viu.
  2. Connecteu l'altre extrem del cable d'alimentació a una presa de corrent adequada.

6. Instruccions de funcionament

6.1 Engegada/apagada

  1. Per encendre el amplifier, turn the power switch on the front panel to the "ON" position. The vacuum tubes will begin to glow. Allow a few moments for the tubes to warm up before expecting full sound quality.
  2. To power off, turn the power switch to the "OFF" position.

6.2 Selecció d'entrada

Press the input selector button on the rear panel to switch between the "CD" and "AUX" audio inputs.
