2. Attenuator (electronics) - Wikipedia

   en.wikipedia.org/wiki/Attenuator_(electronics)

   An attenuator is a passive broadband electronic device that reduces the power of a signal without appreciably distorting its waveform. An attenuator is effectively the opposite of an amplifier, though the two work by different methods. While an amplifier provides gain, an attenuator provides loss, or gain less than unity. An attenuator is often ...

3. Power attenuator (guitar) - Wikipedia

   en.wikipedia.org/wiki/Power_attenuator_(guitar)

   Power attenuator (THD Hot Plate) on Marshall 1959 Super Lead Plexi. A power attenuator, used with a guitar amplifier, is a type of attenuator that diverts and dissipates a portion of the amplifier's power to enable hearing the amplifiers high-volume characteristics at lower volume.

4. T pad - Wikipedia

   en.wikipedia.org/wiki/T_pad

   A T-pad attenuator formed from two symmetrical L sections. Because of the symmetry, R 1 = R 3 in this case. For an attenuator, Z and Y are simple resistors and γ becomes the image parameter attenuation (that is, the attenuation when terminated with the image impedances) in nepers. A T pad can be viewed as being two L sections back-to-back as ...

5. Isolation cabinet (guitar) - Wikipedia

   en.wikipedia.org/wiki/Isolation_cabinet_(guitar)

   "Cranking an amp" means turning up a guitar power amplifier well into the region at which power-tube distortion is produced, generating as much as twice the amplifier's rated non-distorting wattage. Pushing a guitar amp to such an extent can destroy components of an amplifier whether using an isolation cabinet, dummy load, power attenuator, or ...

6. Π pad - Wikipedia

   A Π-pad attenuator formed from two symmetrical L sections. Because of the symmetry, R 1 = R 3 in this case. For an attenuator, Z and Y are simple resistors and γ becomes the image parameter attenuation (that is, the attenuation when terminated with the image impedances) in nepers.

7. Guitar amplifier - Wikipedia

   en.wikipedia.org/wiki/Guitar_amplifier

   The amplifier's master volume control restricts the amount of signal permitted through to the driver stage and the power amplifier. When using a power attenuator with a tube amplifier, the master volume no longer acts as the master volume control. Instead, the power attenuator's attenuation control controls the power delivered to the speaker ...

8. Traveling-wave tube - Wikipedia

   en.wikipedia.org/wiki/Traveling-wave_tube

   Attenuators placed along the RF circuit prevent the reflected wave from traveling back to the cathode. Higher powered helix TWTs usually contain beryllium oxide ceramic as both a helix support rod and in some cases, as an electron collector for the TWT because of its special electrical, mechanical, and thermal properties.

9. Noise gate - Wikipedia

   en.wikipedia.org/wiki/Noise_gate

   An Alesis Micro Gate noise gate. A noise gate or simply gate is an electronic device or software that is used to control the volume of an audio signal.Comparable to a limiter, which attenuates signals above a threshold, such as loud attacks from the start of musical notes, noise gates attenuate signals that register below the threshold.
