Dear Musician Friends,
Our tech support pages are literally a "website within a website". We deal with all aspects of how to install or best use our 2mic designs to get the fabulous sound you want, and without feedback problems. And we try to give you this information in a variety of formats - text, videos, illustrated instructions, etc.
Within the support pages of this website, there should be answers to any questions about the 2Mic and how it is best used. But if anyone cannot find the answers they need, please fee free to contact us at MiniFlex - by email, or telephone - (530) 284-1689. We are always happy to help anyone.
The 2mic design is currently only 6 years old, and it is not hype to say that the 2mic represents a huge breakthrough in microphone design. But along with being innovative comes the sober reality of educating musicians how to best use this new technology. Microphones create a much more complex, overtone-rich electronic signal than pickups, which is why mics tend to sound so much more "natural". Within the amplification field there are separate logic processes for putting gear together in an amplification chain using "pickup logic" versus "microphone logic". What works great for a pickup may not work so well for a microphone - and vice-versa.
Then along comes the 2Mic, which can work great with most old and new gear, but is so versatile it really needs its own "2mic" logic" in order to reach the full potential for great tone quality and feedback control. Though using the 2Mic is not "rocket science" - it does involve a refreshing new way of thinking about how to amplify acoustic guitars.
Please let us help you to learn now to unleash the magic acoustic sound of the 2Mic for your acoustic guitar. And remember, at MiniFlex..."we make you sound authentic".
Troubleshooting Output Issues
The following document addresses some of issues regarding the proper installation of the output jack and which is particular relevant to the MiniFlex 2Mic Model 4, Model and Model 7.
Installation and Placement
The following document is probably the most succinct statement made about this subject regarding mic installation and placement and will be of tremendous benefit to
How to Choose the Right 2Mic Model
Most "common knowledge" within the music industry for amplifying acoustic guitars applies to pickups, which have been used to amplify guitars for over 70 years. Using on-board - or close mic installation of microphones is only about 30 years old, so knowledge within the music industry is still catching up to advance of microphone technology represented by the 2Mic design. When "pickup logic" is used to process a 2Mic signal, sometimes the end result can be disappointing. But when "microphone logic" is applied, the 2Mic will perform spectacularly.
This document will provide some basic information about how microphones and pickups operate. More important there is specific information about the 2Mic, so that you can apply "2Mic logic" to how you use your MiniFlex and get fantastic results in every application.
Cutaway Diagram for Model 1 Installation
The photos below, show a cutaway view of an acoustic guitar with a Model 1 end pin mounted 2Mic installed in the body of an acoustic guitar:
Diagram 1 above shows the whole Model 1- 2 Mic assembly. Please note the
• The complete 2mic assembly hangs from the end pin output jack which is attached to the very thick - 20 mm - 3/4 inch, tail block of the guitar.
• No part of the mic assembly touches any part of the guitar except at the tail block. Unlike many pickups, there is no dampening of the natural acoustic tone production of the guitar by installation of any end pin mounted 2Mic.
2. Long Gooseneck
• The Mic on the long gooseneck is mounted in the vicinity of the sound hole with the white dot on the windscreen pointed towards the interior of the guitar.
• The white dot identifies the active face of the mic.
3. Short Gooseneck
• The mic on the short gooseneck is positioned approximately underneath the bridge, approximately 20 mm beneath the sound board, and with the mic pointed slightly "off axis" - at an angle towards the sound board.
• Also note how there is a small bump on the short gooseneck just below the windscreen. This bump acts as a "feel indicator" to determine the direction of the active face for the mic on the short gooseneck while the 2Mic assembly is installed inside the guitar.
4. Alternative Mic Locations
• Either the mic on the long or short gooseneck can be maneuvered into a variety of alternative locations, which will provide different performance for recording tone and rejecting feedback.
5. Battery Life
• Is approximately the shelf life of the batteries installed. The output jack acts as a "switch" to turn the batteries "off or on" when a plug is inserted. We recommend changing batteries every two years, and mainly to prevent possible damage to the terminals on the battery clips from a leaking battery.

There are 12 MiniFlexMic Models to choose from, designed to fit any amplification situation, for live performances or studio recording.
The Model 1
The Model 1 mounts in the tail block of any acoustic guitar - see cutaway photo above, in place of the standard strap button. The Model 1 is powered by two AA batteries mounted to the main barrel of the 2Mic. It is a tail-block mount design clamping solidly to the end of the guitar. Mics are placed approximately underneath the bridge and in the vicinity of the sound-hole. Because every instrument is unique it is recommended that you test alternative mic locations to find your guitars own "Sweet Spot" for best tone and feedback rejection.
We recommend replacing the AA batteries every two years, and primarily to avoid possible damage from a leaking battery. It is best to completely remove the Model 1 from the guitar to change the batteries. The installation tool provided for free with the Model 1 is also good for helping to change the batteries.
The Output Connector - end pin output jack, for our 2mic system is a Mono 1/4" phone jack, using a standard guitar cable. Power is only used when your 2Mic is plugged in, the 1/4" jack acting as an on/off switch.
The Model 1 creates a 3.5K ohm line level signal, and is compatible with most equalizers, effects devices, and DI boxes.
Note: Please see the section entitled: "Line Level signal Compared to Mic level Signals" on page 3 of the support document titled "How to Choose your 2Mic" to learn more about the differences between line level and mic level signal strengths.
The Model 1 will perform best through a high quality P.A. system, or "acoustic" guitar amp. But the Model 1 should also work just fine through most any guitar, bass, or keyboard amplifier. For most PA system and acoustic amps, we recommend using the "XLR mic input" with a standard 1/4" mono guitar cable attached to the 1/4"-XLR adapter provided for free with the Model 1. This can be useful for connecting the Model 1 into the XLR input of a P.A. or acoustic amp.
The Model 2
The Model 2 is a quick mount 2Mic using the same mic elements and electronics as the Model 1, except that the Model 2 is the only 2Mic that has a volume control on board the mic assembly.
For the Model 2, both mic elements are mounted on to a single gooseneck that will attach to the edge of the sound hole along the bass side of the fingerboard, leaving the mic in the center of the gooseneck pointing into the sound hole, and the mic on the end of the gooseneck pointing towards the interior of the guitar.
The Model 2 is an excellent choice for musicians who want to amplify more than one guitar using a single 2Mic model.
The battery and the electronics are located inside a plastic service module that is secured to the guitar using an elastic mount that attaches to the strap button at the heel and tail block of the guitar.
The Model 2 is powered by a single AAA battery located inside the service module. The jack on the service module acts as a switch to turn the battery on when a plug is inserted into the jack.
A 1/4" - XLR adapter (included), permits plugging the 2Mic into low impedance XLR inputs, which may improve performance through some amplifiers and PA systems, and especially when a snake is used.
General Information for both the Model 1 and
the Model 2
On all our battery operated 2Mics, we recommend replacement after two years because that is the normal shelf life of a battery. Power is only used when your 2Mic is plugged in, the 1/4" jack acting as an on/off switch.
The Output Connector for our 2mic system is a Mono 1/4" phone jack, using a standard guitar cable.
A high quality P.A. system, or "acoustic" guitar amp will provide the best possible amplified sound quality and feedback control. For most PA systems, use the "line input" with a standard 1/4" mono guitar cable. Experiment with both 1/4" phone and XLR inputs for acoustic amps.
• EQ-Effects-direct boxes: Model 2 is compatible with most AC or battery operated effects devices & direct boxes.
• Feedback: The Model 2 2Mic will deliver more volume without feedback than any single mic system. But, feedback can sometimes occur when the 2Mic is used in small rooms, through electric guitar & bass amps, or when played at extremely high volumes. All microphones, including the 2Mic love lots of "air", and need a high quality PA system, in a good room to perform at their best.
