Description
A few minor minor marks on top and faceplate-see pix One of the pixels on the last digit is out ,seems to be common for these tuners Sounds really good Specifications Type: Mono/Stereo Tuner Tuning Bands: FM, MW Tuning Scale: Digital FM Tuning Range: 88 to 108 MHz Sensitivity: 1.8uV (FM), 300uV (MW) Signal to Noise Ratio: 75dB (FM) Distortion: 0.3% (FM) Selectivity: 70dB (FM), 35dB (MW) Frequency response: 30Hz to 15kHz (FM) Dimensions: 420 x 108 x 380mm Weight: 4.25kg NAD 4130 (1986, $230, photo) search eBay We'll leave this one to our contributor Zeljko: This simple PLL tuner uses a Matsushita front end with the electronic equivalent of 4 gangs, offering good selectivity and decent image rejection - nothing spectacular for the latter but certainly excellent for the price! The tuning system provides 5 presets for each band, frequency, 'tuned' and centering indications. The IF uses matched ceramic filters with amplification in between and, while not cutting off the sidebands to utmost perfection (like some $1,000 tuners!), it offers less distortion and better sound quality for the frequently overmodulated local stations. Although typically NAD no-frills (to the point of being nondescript), this tuner does have an interesting feature that is never seen on such a cheap device: dynamic FM hi-blend noise reduction. Unlike fixed FM blends, or those with steps, this system actually monitors the output signal for HF noise created by FM de-multiplexing and dynamically adjusts the amount of mono-to-stereo blending to cancel out the distortion. This useful feature is also defeatable, when you want to listen to the purest sound from a high signal station. Like most inexpensive digitals, the 4130 tunes in 200 kHz increments. Our panelist Bob adds that the 4130 has a single IF path and uses a quad detector, the LA3380 MPX chip, and an NJM 4023 dual op-amp per channel on the outputs. The ceramic filters are configured as follows: mixer, single-tuned IF t-x, JFET amp, CF1, LA1222 amp, CF2, LA1222 amp, CF3, LA1235 limiter/detector chip. The 4130 can usually be found for $20-50 on eBay

A few minor minor marks on top and faceplate-see pix One of the pixels on the last digit is out ,seems to be common for these tuners Sounds really good Specifications Type: Mono/Stereo Tuner Tuning Bands: FM, MW Tuning Scale: Digital FM Tuning Range: 88 to 108 MHz Sensitivity: 1.8uV (FM), 300uV (MW) Signal to Noise Ratio: 75dB (FM) Distortion: 0.3% (FM) Selectivity: 70dB (FM), 35dB (MW) Frequency response: 30Hz to 15kHz (FM) Dimensions: 420 x 108 x 380mm Weight: 4.25kg NAD 4130 (1986, $230, photo) search eBay We'll leave this one to our contributor Zeljko: This simple PLL tuner uses a Matsushita front end with the electronic equivalent of 4 gangs, offering good selectivity and decent image rejection - nothing spectacular for the latter but certainly excellent for the price! The tuning system provides 5 presets for each band, frequency, 'tuned' and centering indications. The IF uses matched ceramic filters with amplification in between and, while not cutting off the sidebands to utmost perfection (like some $1,000 tuners!), it offers less distortion and better sound quality for the frequently overmodulated local stations. Although typically NAD no-frills (to the point of being nondescript), this tuner does have an interesting feature that is never seen on such a cheap device: dynamic FM hi-blend noise reduction. Unlike fixed FM blends, or those with steps, this system actually monitors the output signal for HF noise created by FM de-multiplexing and dynamically adjusts the amount of mono-to-stereo blending to cancel out the distortion. This useful feature is also defeatable, when you want to listen to the purest sound from a high signal station. Like most inexpensive digitals, the 4130 tunes in 200 kHz increments. Our panelist Bob adds that the 4130 has a single IF path and uses a quad detector, the LA3380 MPX chip, and an NJM 4023 dual op-amp per channel on the outputs. The ceramic filters are configured as follows: mixer, single-tuned IF t-x, JFET amp, CF1, LA1222 amp, CF2, LA1222 amp, CF3, LA1235 limiter/detector chip. The 4130 can usually be found for $20-50 on eBay
