It offers adjustable treble, midrange, and bass tone controls with a wide frequency response and a high-performance NE5532 op-amp chip. Ideal for experienced hobbyists, this kit delivers professional audio quality with easy assembly and mod-friendly design, making it a top choice for custom audio projects. ## Description Product description Description High quality filter power supply. The four pins of rectifier respectively in parallel connect with decoupling capacitor, which can effectively eliminate the high frequency interference of AC power grid. Two 2200UF25V electrolytic capacitor filter the negative power supply, then stabilize voltage with 7815 and 7915 double DC power supply. Now the clutter interference of power grid is very small and the voltage is quite stable. So the item has better performance.The chip has high conversion rate and strong drive ability. The frequency band is wide and noise is very small. Specifications Note 1, The amplifier board can not use 12 V battery or DC directly as power supply. Power supply should be positive and negative double DC power sources, or special AC 12 V transformer power supply. 2, This item need a power amplifier to drive speaker. 3, Please allow 1-3 mm error due to manual measurement. Thanks for your understanding. 4, Monitors are not calibrated same, item color displayed in photos may be showing slightly different from the real object. Please take the real one as standard. Working Voltage: AC double 15 V (10 W) Audio Input: RCA sockets Audio Output: 3P terminal Input Voltage: 3P terminal Size: 110 mm x 54 mm x 22 mm Package includes: 1 x Pre-amplifier Board DIY Set I built this as part of my home-build 200 watt amp system. I haven't installed it yet, as the build is on hold for additional parts. Once I do installed it I will write another review as to its performance. The way I use these types of products is that I start with a 19 inch rack mount 2U or 3U chassis and I’ll stuff a toroidal transformer, a full wave bridge rectifier and filter cap board, an input selector board (+15vdc), a speaker protection circuit board (+12vdc), a blue tooth receiver board (+5vdc), this preamp/tone board (+/-12vac**), a low pass filter/subwoofer summing preamp (+/-18vac), a dual channel VU meter driver board (+12vdc), a dual channel fixed gain current amplifier that drives the L/R speakers w/200w @8ohms (+56vdc) and finally a single channel/mono current amplifier the drives a passive subwoofer w/500w @4ohms (+48vdc). And sometimes the person who commissions the custom built amp wants to play some vinyl, I will add a RIAA phono preamp (+15vdc) I build professional quality products using a modular approach. I chose this preamplifier because it was a do it yourself kit, and uses a very popular and very stable operational amplifier (op-amp) that provides good gain, A very good signal to noise ratio, acceptable harmonic distortion, good input impedance and with a 400-600mV input signal this will easily drive β€˜any’ amp board you choose. Review: quality components, very well designed, easy assembly. - Quality components, very nice board, well designed. Easy to assemble for most experienced hobbyists. The circuit is easy to modify the shelving frequencies of the bass, mid, and treble to suite other applications such as musical, vocal, pa applications. This is accomplished by scaling down the bass caps (0.047uF) and scaling up the treble caps (2n2) by an equal amount. The mid may also be moved too in whatever direction desired. The center frequencies are approximately 20khZ, 800hZ, 20hZ as the kit comes. The overall gain is 10 and that too can be changed by the resistors around the first 5532 op-amp. Further mods are with power supply. You can eliminate the bridge rectifier and jumper + to ac terminal and - to other ac terminal if you already have DC power from somewhere else that is at least +20 volts AND -20 volts (not to exceed +35, -35 volts) plus a ground (neutral), it must be bipolar! The circuit will operate on lower voltages but will require you to put jumpers in place of the voltage regulator I.C.'s and lower voltages will reduce signal swing and hot signals may cause overload (clipping). No need to install the 2200uF caps since the 100uF and 0.022 caps are adequate for decoupling the supply and it could cause power-up surge issues somewhere else. Excellent value for the price. Board is very high quality as are the pots and components. Parts alone would well exceed the price of the kit alone. Built, modified and tested my own kit with 100% success! Very satisfied and highly recommend. Please note there are no instructions or documentation of any kind, so this kit is for more experienced builders. Review: Nice Clean Preamp - This was a fun, easy kit, no schematics or guess work. It sounded so good I bought another one for my other system. The only part that required any skull sweat was the enclosure I put it in. I have the first one rack mounted on 1/8 aluminum rack panel. The panel needed to be thinned out the allow the threads on the potentiometers enough room the accept the nuts and washers. The maximum thickness is about .065 inches. The pot shafts fit in 9/32" holes and the spacing in about .932 inches. A hair under an inch. Have fun!!! ## Features - Power supply circuit adopts full bridge rectifier, the four pins of rectifier is respectively in parallel connected with decoupling capacitor, effectively eliminate the high frequency interference of AC power grid - The chip has high conversion rate and strong drive ability, which will greatly help your project - Small clutter interference of power grid, stable and performance - Wide frequency band and small noise, easy to use - Pay attention that it can not use 12V battery or DC directly as power supply ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B075RZG9HT | | Best Sellers Rank | #98,850 in Electronics ( See Top 100 in Electronics ) #614 in Audio Component Amplifiers | | Brand | Walfront | | Brand Name | Walfront | | Customer Reviews | 3.9 out of 5 stars 82 Reviews | | Item Dimensions | 43.31 x 21.26 x 8.66 inches | | Item Weight | 0.07 Kilograms | | Item dimensions L x W x H | 43.31 x 21.26 x 8.66 inches | | Manufacturer | Walfront | | Material Type | Printed Circuit Board (Pcb) | | Maximum Supply Voltage | 15 Volts (AC) | | Minimum Supply Voltage | 15 Volts (AC) | | Model | Walfrontt5sq06xcz3 | | Mounting Type | Surface Mount | | Number of Channels | 2 | | Output Power | 10 Watts | | Package Type Name | Cardboard Box | | Part Number | Walfrontt5sq06xcz3 | | UPC | 663862207798 | ## Product Details - **Item dimensions L x W x H:** 43.31 x 21.26 x 8.66 inches - **Manufacturer:** Walfront - **Maximum Supply Voltage:** 15 Volts (AC) - **Minimum Supply Voltage:** 15 Volts (AC) - **Mounting Type:** Surface Mount ## Images ![NE5532 Amplifier Kit Stereo Preamplifier Volume Control Board with Treble Midrange and Bass Tone Controls DIY Kit Preamp Module - Image 1](https://m.media-amazon.com/images/I/5118EW+RXuL.jpg) ![NE5532 Amplifier Kit Stereo Preamplifier Volume Control Board with Treble Midrange and Bass Tone Controls DIY Kit Preamp Module - Image 2](https://m.media-amazon.com/images/I/51Ze4hG-vkL.jpg) ![NE5532 Amplifier Kit Stereo Preamplifier Volume Control Board with Treble Midrange and Bass Tone Controls DIY Kit Preamp Module - Image 3](https://m.media-amazon.com/images/I/41kihtnrbDL.jpg) ![NE5532 Amplifier Kit Stereo Preamplifier Volume Control Board with Treble Midrange and Bass Tone Controls DIY Kit Preamp Module - Image 4](https://m.media-amazon.com/images/I/41CLbxKtOfL.jpg) ![NE5532 Amplifier Kit Stereo Preamplifier Volume Control Board with Treble Midrange and Bass Tone Controls DIY Kit Preamp Module - Image 5](https://m.media-amazon.com/images/I/411jIVjyuEL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ quality components, very well designed, easy assembly. *by S***N on March 20, 2023* Quality components, very nice board, well designed.
