1. New Pyle PHE300 Compact DJ/Studio 2-Channel Hum/Noise Destroyer Headphones Amps

Pyle 2-Ch. Hum/Noise Destroyer 2-Channel Hum/Noise Destroyer Removes AC Hum Noise Breaks Ground Loops Safely Maintains Highest Sonic Quality High-Performance Ultra-Compact Design High-Quality Components and Exceptionally Rugged Construction (2) 1/4-Inch TRS Inputs and Outputs for 2-Mono or 1 Stereo Signal Automatically Converts Unbalanced to Balanced Signal Without Any Signal Loss Almost all 60Hz AC hum is caused by ground loops that act like radio antennae (loop antenna). The Hum Eliminator completely eliminates this by breaking the ground loop, making it impossible for the signal lines to pick up the AC hum and noise in the first place. Unbalanced lines are more susceptible to picking up electrical noise and RF interference than balanced lines - the longer the unbalanced cable, the greater the chance of a problem. Using this device to connect two pieces of equipment is one of the most cost-effective ways to convert between unbalanced signals and true balanced signals. Automatically Translates Signal Voltages to Match Difference in Ground Potentials.

REMOVES AC NOISE: The Pyle Hum Eliminator removes 60Hz AC hum caused by ground loops that act like radio antennae (loop antenna). Breaks the ground loop safely making it impossible for the signal lines to pick up the AC noise in the first place. PASSIVE DEVICE: The noise isolator is a passive device which does not require power to operate. Equipped w/ ¼” TRS phone inputs and outputs on 2 channels. Automatically translates signal voltages to match the difference in ground potential. COMPACT DESIGN: This noise filter device features a high performance ultra compact and portable design allowing you to easily bring it anywhere. It has high quality components and rugged construction while maintaining the highest sonic quality. UNBALANCED TO BALANCED SIGNAL: Automatically converts unbalanced to balanced signal without any signal loss and is responsible for breaking the ground loop or the loop antenna that prevents buzz for a clear sound. Accepts mono or stereo connections. This unit is designed to reduce or eliminate hum noise caused by AC 160 HZ Electric hum, or faulty ground loop. It will not solve noise caused by defective components. Connectors: 2 x 1/4" / 6.3 mm TRS Female Inputs. 2 x 1/4" / 6.3 mm TRS Male Outputs.

5. Electro-Harmonix 12AX7EH Preamp Tube

The Electro-Harmonix 12AX7EH is a preamp tube that provides high gain with ultra low noise. The tube's detailed, musical tone rivals the most desirable NOS types. Unique spiral filament eliminates the filament-to-cathode induced hum common on amps that use AC on the filaments.

6. Groove Tubes GT-ECC83-S Preamp Tube

Our highest-gain preamp tube, this tube has a huge amount of gain, with terrific output that makes it a great choice for driving modern, complex high-gain circuits. It has a relatively high quality variance (making Groove Tubes pre-testing procedures especially important in this case), with a tight, strong and relatively bright tone that can really liven up a weak or tired old vintage amp or a new amp with grade-quality tubes.

7. Groove Tubes GT-12AU7 Preamp Tube for Guitar Amplifiers

Groove Tubes GT-12AU7 Preamp Tube for Guitar Amplifiers

Guitarists both yesterday and today can be linked by one piece of equipment: The tube amp. With all the strides in transistor amp technology, guitarists still prefer tube amps. Why do tube amp designs sound and feel differently from solid-state? Simply, tubes work differently. These are commonly used as phase inverters in McIntosh Hi-Fi amps, some Ampeg amps, and will yield the most clean headroom in many amps. In the latest Fender Pro Series amps such as the Pro Reverb, Concert, and Twin, this tube in V2 (or a 12AY7), will drop the gain of the gain channel where some feel the tone is of a less intense or “buzzy” character. This will then allow a much wider range in the sweep of the volume and gain controls of this channel.

10. Studio Projects SPM5 500-Series Mic Preamp

Designed by the creator of Tonelux, the Studio Projects SPM5 is a unique high quality microphone/instrument preamp with an added 'radiance' feature, which provides adjustable high end 2nd harmonic content to your signal without boosting overall output. This is useful for adding clarity and presence to your signal source. The input circuitry is discrete, while the output is transformer balanced. The preamp provides a clean, low-noise 60dB of gain. The front panel features a combo jack for plugging in directly and there is an impedance switch, which can be useful when employing certain microphones, such as ribbon, or dynamic type. Radiance The radiance control, located just above the multi-jack on the front panel, is used to add 'sparkle', or 'clarity' to the input source signal. This effect can be used sparingly,or heavily, depending on the how far clockwise the radiance control is adjusted. Polarity The "POL" switch reverses the polarity of the microphone signal. It can correct for the wiring of older, non-AES equipment, change the character of the sound from guitar mics and, when using two mics for "Mid and Side" stereo recording, invert the phase of one of them. High Pass Filter ('HPF') This helps remove stage rumble, handling noise and low frequency resonances. The cut frequencies are continuously variable from 25Hz to 200Hz. Adjust the control so that the unwanted sounds are removed but required sounds do not lose their bass content. Use the HPF 'ON' switch to make comparisons between filtered and unfiltered sound. Gain and Noise All preamplifiers inevitably generate some noise due to the electronics they require. As long as this is low compared with what you are trying to record, the signal will hide the noise. In fact the SPM5 electronics are extremely quiet, such that almost all the noise is due to the source impedance of the microphone. However, you might still hear some "hiss" during the gaps in the vocal or music. Bearing in mind the amount of gain in a typical monitoring system, it is generally a good idea not to use preamp gains greater than 40dB or 50dB. With careful microphone placement, it should rarely be necessary to do so. So try to place the microphone as close to the sound source as you can without overloading it, so as to get as much signal out of it as possible. Then set the 'GAIN' control to give only as much gain as is needed to get a decent level on the meter.
