Many of our readers have written and requested that we review some affordable, yet high quality, receivers. We chose the Yamaha RX-V592 because not only is it inexpensive, but it has a full set of 5.1 pre-in jacks and pre-out jacks so that users can connect decoded 5.1 signals, such as DD and DTS. The 592 has 75 watts each to the front left/center/right and 35 watts each to the rear left/right. Although this is fine for a starter system, the pre-out jacks are immediately available for connection to an outboard five-channel power amplifier. One nice feature here, is that the 5.1 inputs include a subwoofer input that is the 0.1 channel or LFE (Low Frequency Effects) channel input missing from previous receivers.

Yamaha RX-V592 Rear PanelThe rear of the 592 has the 5.1 pre-ins and pre-outs nicely arranged by themselves (in the photo, they are the six jacks on the upper left and upper mid-right of the rear panel). It is almost as if Yamaha expects you to use them right away, and that is exactly what we did. Besides the ubiquitous phono preamp inputs, there are audio inputs for CD, tape (with loop), DVD/LD, TV/DBS, and VCR. Video inputs (coaxial only, no S-Video) include DVD/LD, TV/DBS, and VCR. There is a monitor out jack and VCR out jack (coaxial). The speaker terminals consist of binding posts for the front left and right, while for the center and rear left/right, spring clips are used. These spring clips are too small for banana plugs, but bare wire or small spades will fit. An impedance selector allows using 4 or 8 Ohm speakers, and the 4 Ohm selection limits voltage so the amplifier won't go into orbit. Two switched AC outlets are useful for turning on small components, and we used one of them to trigger an AC Power Conditioner that turns on a power amplifier and subwoofer on a timed basis.

yamaha592remotelarge.jpgThe illuminated remote control for the 592 is much like the other remotes for the latest Yamaha receivers, and is very basic, yet allows learning from other remote controls, and is programmable with macros. You can select the input, control VCRs and DVD players (circular arranged buttons at the top left of the remote control photo), select DSP sound fields (Pro Logic Enhanced, Concert Video, Mono Movie, Stadium, Disco, Rock, and Hall. When using the 5.1 pre-ins, DSP modes are not available. The 592 in that case becomes a volume control center for the DD or DTS analog input signals. Master volume is controlled with the circular buttons shown at the bottom right of the control in the photo at the right. You then use the buttons above the master volume, also arranged in a circle, to adjust center and rear channel volume. As we have mentioned several times, we prefer going direct from the video source to the TV, especially with DVD, where the signal is greatly improved by using the S-Video output from the player rather than the composite video output.

The FM/AM tuner has 24 presets for the FM section, and 16 for the AM section. It performs modestly, and is fine for a small system. There is a test tone function, for setting the volume of the various channels. A bass extension button on the front provides + 6 dB at 50 Hz, and the treble and bass controls give ± 10 dB at 20 kHz and 50 Hz, respectively. Although the front channel amplifiers are rated at 75 watts rms, 20 Hz - 20 kHz, 0.04% THD, the center channel is rated at 75 watts rms, 20 Hz - 20 kHz, 0.07% THD, and the rear left/right are 35 watts rms, 1 kHz, 0.3% THD. Thus, the center has slightly less performance than the front left/right, even though they are 75 watts, and the rear is not rated at full spectrum, and so, probably delivers about 25 watts, 20 Hz - 20 Kz. Again however, this is an entry level system.

The front panel display is uncomplicated, and indicates basic information, such as shown below.Display with DVD Input For use with 5.1 inputs, you have to select the DVD/LD input and then switch to the 6 channel mode (5.1 is actually 6 channels, including the LFE or subwoofer). None of the DSP sound fields are available with 5.1, and only the volume control is active (tone controls active to front channels), but many of the DVD players emerging now have the ability to adjust several facets of DD sound, and that should be sufficient in a small system. Display with VCR InputWhen using a VCR and Pro Logic, the display shows the input and the fact that Pro Logic is the decoding method.

We tested the 592 with a Yamaha DVD-S700 DVD Player, Krix Speakers, and Nordost Cables. The Krix are 8 Ohm loads with modest sensitivity. The sound from the built-in amplifiers is typical of mid-priced mass market products. It is OK as long as you don't turn the volume up very loud. Since this is an entry level receiver, the performance was about as expected (I got 80 dB SPL when using only the front left/right channels, before clipping began to set in). However, the real selling point of the 592 is that it is capable of being connected to outboard 5.1 processors and outboard power amplifiers. We used the 5.1 analog outputs of the DVD-S700 to send decoded DD sound from DVD movies, as well as the analog outputs from a Millennium 5.1 DTS decoder for DTS signals from DTS CDs, and the 592 worked very well for this. When I put in a Carver AV-705x five channel power amplifier, the system really opened up, and I was able to get a great deal more impact to the digital surround sound. In the meantime, the 592 will handle movie sound tracks pretty well, until the time you can afford the more powerful amplifier.

592 Square Wave ResponseSquare wave response of the 592 at 10 kHz, ± 10 Volts, shows no ringing or overshoot. However, the speaker output bandwidth is limited to 62 kHz (the point at which the sine wave response was down 3 dB from where it was at 10 kHz). The photo shows the response through the left speaker output. Bandwidth appears to be a little higher using the 5.1 pre-outs (69 kHz). DC offset at the speaker output was - 3.4 millivolts, and very close to 0 using the 5.1 pre-out jacks.

In summary, the Yamaha RX-V592 is an attractive receiver for those consumers who want to get into home theater, and who want to be able to upgrade to digital surround later, without setting aside what they already have. The 5.1 pre-ins and 5.1 pre-outs allow connecting any outboard digital decoder as well as any five channel outboard power amplifier for a complete and up-to-date digital surround sound system. It is an uncomplicated, easy to use, and nicely featured unit that is well worth a look.
