High Gain All-In-1 Phono Preamp Microphone Preamp Stereo Preamp
This high gain stereo preamp device incorporates a high gain and accurate
phonograph stage, a microphone stage, and an auxiliary input stage. Gain level or
volume control is adjustable from the front panel.
This all-in-1 pre-amplifier is designed to boost the output
of a low-level audio source such as turntable, vinyl
record player, tape deck, microphone and
virtually any line level audio device such as mp3 player, portable CD player,
computer sound card, instrument preamp, etc. Such boost to increase output sound level is needed in many
applications such as loud speaker setup, audio recording, party, live stage
event for better performance results or for longer cable run between
This device provides handy solutions for applications requiring sound level to
be magnified first when you want to:
- connect a LP player or turntable to stereo
amplifier, audio mixer,
powered speakers, recorder, computers and other
- connect a MP3 player to a receiver or home
- connect microphones to amp or receiver.
- connect auxiliary source or karaoke
player to amp or receiver.
- have an extra volume control mechanism between
the audio source and the amplifier.
- boost the signal level for audio to be
transmitted over long cable wire without loss of quality. A great
necessity when connecting the TV audio output or CD/DVD player in living room to
the stereo system located in family room.
Users can also use this stereo preamp to record
playback of vinyl records from turntables or cassette tapes from tape deck thru
computer sound card and save the digitized files onto hard disc for music
collection as well as
producing CD copies and MP3 songs.
This high-gain low-noise pre-amp
is ideal for both home and professional studio, computer multimedia production,
karaoke and mixer application. External preamp like this unit provides lower
noise floors than those built into consumer-grade stereo receivers.
Bring Vinyl To Life
In the digital music age, your old vinyl and LP collections have new life to turn
with help from this phono amp. This device provides users with a cost effective
solution for boosting the output from the turntables and magnetic
pick-up cartridges with
RIAA equalization to harmonic line level as CD, tape deck, radio tuner, or
auxiliary source before reaching the
amplifier, receiver, mixer or the line-in of computer
sound card for the high-fidelity sound of real vinyl.
This device is also
strongly recommended for the setup if you suddenly come to realize the
superiority of vinyl and LP playing for what natural and real music should sound
would like to get your classic albums off the
shelf and into your MP3 player.
It can also be easily integrated with
those Hi-Fi systems with phono inputs or adding extra phono
input for existing stereo systems and amplifier
Signal Level Enhancement
Applications such as
recording microphone or instrument sound into the computer sound card or
connecting MP3/iPod to home theater system have one big task to tackle, audio signal levels
from these devices are simply too low to record or play. What
to do ?
With the amplification provided
by this unit, the low level output from the portable audio devices and music
instruments can be enhanced to the level needed for recording deck and
sufficient to drive your amplifier, loud speakers or
audio receiver properly with ultra low noise and
outstanding sound performance. No more cranking the master volume control on
The 3.5mm mini stereo input on the front panel for
input provides significant boost of 20dB so music from iPod or any portable CD can
be played smoothly through your home stereo or Hi Fi system. This unit can also be used as
the amplifier for your karaoke players or CD/DVD player to transform your stereo
music to thrilled sound for party or outdoor events.
This ultra-quiet preamp
offers features and performance needed to track great sounding music. It
provides both the playback equalization and the
signal amplification for line-level devices.
Adjustable Gain Level Control
This pre-amplifier provides up to 60dB of gain including 40dB phono stage gain plus
additional 20dB of adjustable gain to drive insensitive
inputs or overcome
signal level losses caused by a long cable run to the amplifier or receiver.
The dial on the front panel of this unit allows
users to progressively control the gain level through 3 major steps of "Attenuate",
"Normal" and "Boost". This dial can also be used as an
external volume control mechanism for
any analog audio device or stereo amplifiers with no output level or volume adjustment
of its own. Users can control the volume level from this
pre-amp directly. No more cranking the master volume control on the receiver or
power amplifier at home or live event.
Multiple Audio Inputs
This rugged pre-amp is
featured with multiple audio inputs in RCA phono jacks, DIN jack, 3.5mm stereo mini jacks and microphone
input for connection with multiple audio sources:
- Phono and DIN input for phono devices
such as record players, MM cartridges.
- Auxiliary input for TV, CD/DVD player,
karaoke player, radio tuner, stereo system, satellite receiver, etc.
- 3.5mm input for iPod, MP3, computer or other
portable music players.
- Dual microphone inputs, also for left and right
Sometimes you need to connect a low-impedance or condenser microphone to
something which does not support it, such as a high-impedance mixer input, a PC
sound card, a powered speaker or possibly an instrument amp. Situations like
this call for a mic preamp like this unit to act as an interface.
This microphone preamp is featured
with two microphone inputs and supports all
dynamic, condenser-type and regular microphones with max gain of 20dB.
Condenser-type microphones are the most
common types of microphones used in studios and require power supply. A
push button is located on the back of this unit for user to choose which type of
mic to be used for input. When pressing
this button to select "Condenser" mode, this preamp will supply the
power needed for your microphone to be used.
This unit is great for
studio and stage applications. A great way of
adding the microphone
inputs to existing amplifiers that do not have one or providing additional mic input for audio
receiver/mixer or stereo amplifier without mic input of its own. The level
control is located on the front panel.
[Note]: When a single microphone is used,
users can simply plug the microphone into the right-channel mic jack on the
front and the microphone sound will come out in stereo from both left and right
Stand Alone Volume Controller
This unit can also be used to provide an external way of volume control
mechanism for any audio source device or power amplifiers that do not have
output level adjustment of its own. A volume control dial for variable line
level output is located on the front panel. Users can control the volume level
from this pre-amp directly. No more cranking the master volume control on the
receiver or power amplifier at home or live event.
