Sherwood RX-4105 2-Channel 100-Watt Stereo Receiver Review

Average Reviews:

(More customer reviews)This Sherwood (noted brand years ago, now mysterious) might be a decent bargain for twice the money. It's stripped down by present standards -- two channels only, no phonograph input. It's dead quiet and extremely clean sounding. I can't hear any emphases or dead spots in the frequencies. The tuner is exceptionally good; I am surprised at the success I'm having with it in a poor reception area, with only the antennas that are supplied. Appearance and quality are fine: nice black steel case, solid buttons, one big old volume knob. It was all I needed, so I'm very pleased. Going to get another for a computer amp.

Sherwood's incredibly affordable RX-4105 offers integrated preamplification and amplification, inputs for numerous audio source components, and advanced radio tuning and station access. The receiver delivers 100 watts RMS per channel x 2 for strong, clear sound across the audible spectrum--even at low listening levels. The company has lowered the amplifier's distortion relative to the previous model (the RX-4105), to less than 0.08 percent, while also giving the receiver a new layout borrowed from its higher-end components.The RX-4105 uses totally discrete amplifiers for all channels (TDAS) to maintain its high power and low distortion. Use the receiver's A and B clip-type speaker outputs to power 2 different rooms, or to biwire a pair of speakers for more efficient amplification (with A outputs driving the woofers, for instance, and the B outputs driving the tweeters--make sure your speakers are compatible if this is a key feature for you).The receiver also offers a handy 25-key remote control and switching for 2 pair of loudspeakers. Audio inputs switch between and amplify up to 4 additional components, including 2 requiring both inputs and outputs (such as a cassette deck and a VCR). The built-in AM/FM tuner features 30 station presets and auto station setup.Other features include bass and treble tone controls, a dimmable fluorescent display, and a .25-inch headphone jack for private listening.What's in the Box Sherwood RX-4105 receiver, remote control, AC power supply cord, FM indoor antenna, AM loop antenna set, and owner's manual.

AudioSource Amp 200 High-Current Stereo Amplifier (80 Watts x 2) Review

Average Reviews:

(More customer reviews)My first impression on unpacking the AMP200 was its weight for an amplifier of this size, 11 kgs (just over 24 pounds) !
The front panel is black brushed metal, and has three sets of push buttons on the left hand side (power on/off, speakers A on/off, and speakers B on/off). On the right hand side there are two controls, one for adjusting the left/right balance, and one for adjusting the volume trim (-12 dB/+6 dB). Each of these controls clicks into the center (unadjusted) position. In the center of the front panel is an indicator light which glows a bright blue when the amplifier is operational or red when the amplifier is in standby mode.
On the back of the amplifier are various connectors, switches, and small adjustment knobs, as well as the connector for the detachable power cord. The speaker binding posts accept either bare wire cable or banana plugs (not spades).
I would highly recommend reading the five page Owner's Manual before setting up the unit, as the controls on the back of the amplifier are not readily accessible once it has been installed into a rack !
For my purposes, I'm using a single stereo source into RCA inputs (when using only one signal source you need to use the Line 2 inputs rather than Line 1). The power mode of the unit is also configurable via a three position switch for either normal power operation using the front panel on/off button, to be remotely controlled by a DC trigger, or by means of automatically sensing the input signal. I opted for the latter, and the amplifier comes out of standby mode within a few seconds of sensing a signal and goes back into standby mode if no signal is received for approximately three and a half minutes.
At less than $ 250, I'd rate this as a nice quality amplifier with good sound.

A terrific choice for a remarkably affordable system upgrade or building block, the AudioSource Amp 200 high-current stereo power amplifier offers 80 watts RMS per channel x 2 or, in bridged mono mode, up to 250 watts x 1 (into 8-ohm speakers in both cases). Now you can scale your listening to match your budget: use either 1 amplifier or 2 for stereo sound or 5 or more in concert for full-blown home-theater excitement--perfect for your DVDs, multichannel DTV broadcasts, or high-resolution audio formats like DVD-Audio and SACD.Keep in mind that this is an amplifier only, with no volume control or onboard surround processing (though it does offer independent adjustable output controls for each channel). It's designed for use with a stereo preamplifier or a surround receiver offering preamplifier outputs.Making the move from 5.1- to 6.1- or 7.1-channel surround sound? If your receiver has preamp outputs for all channels, there's no need to replace your 5.1 surround receiver. Just feed the additional center or surround signals to a strategically positioned Amp 200.Connections consist of a choice of RCA (line-level) or clip-type (speaker-level) inputs and banana-plug-friendly binding-post speaker terminals for outputs. There's also set of stereo (left/right) RCA passthrough jacks for use in a daisy-chain setup.The amp works with 12-volt power-on/-off circuitry and also features a signal-sensing circuit for automatic power-on/-off, making it as ideal for custom installers as for end users. Its A and B speaker outputs let you power speakers in your main room, a second room, or both rooms simultaneously. The amplifier's toroidal power supply keeps distortion extremely low (less than 0.04 percent).
