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 | #64,706 in Electronics ( See Top 100 in Electronics ) #378 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 | | 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) ## Customer Reviews ### ⭐⭐⭐⭐⭐ quality components, very well designed, easy assembly. *by S***N on March 20, 2023* Quality components, very nice board, well designed.
