PioneerVSX-918V A/V Receiver
A large, bright-orange MCACC logo gaudily celebrates Pioneers auto-setup and room-EQ features. I rarely use auto setup. My SPL meter is virtually an extension of my hand, and I need to know how amps sound in their virgin state. But MCACC will get the surround newbie up and running with minimal fuss. If you prefer to tweak your receiver manually, Pioneer recommends that you run the auto setup, then copy the settings to the custom menu and take it from there. The VSX-918V is rated at 95 watts of continuous power times ve (not seven). The 120 watts that Pioneers Website lists uses a more lenient specication method. As always, our test report contains the most credible numbers. This receiver and its two lower-priced siblings include new Pioneer Hybrid Amplifier Technology (PHAT). The name conjures up a very relaxed late-night meeting between engineers and marketers: Duuuude, lets make up a name so that the acronym is PHAT. Awesoooome! According to Pioneer, PHAT includes hand-selected parts, automatic temperature compensation, and power modules that minimize internal and external electromagnetic interference. This receiver sounds noticeably cleaner than the last similarly priced Pioneer receiver I reviewed, so maybe theres something to it. The receiver supports AM, FM, Sirius, and XM Radio, but not
cheap seats at Carnegie Hall. They dont provide best-case performance, but if youre living on a tight budget, youre just happy to be there. A budget A/V receiver can also form the basis of a starter system for the hardheadedly practical person whos dubious about surround sound but doesnt want to be left behind. Pioneer has two receiver lines, the higher-end Elite and a valueoriented line without any special moniker. The Pioneer VSX-918V hails from the value line where it is second from the top. At $349, it wont strain anyones budget. Although it doesnt have onboard decoding for the latest lossless and
other surround codecs, it can accept a high-resolution PCM signal from a Blu-ray player that does its own decoding. As youll see later, that comes in handy. Im going to depart from the norm and tell you my conclusion up front. The VSX-918V outperformed my expectations. This is quite a fine-sounding budget receiver. So keep on reading. The VSX-918V is a black box with a volume knob on the right and a matching source-select knob on the left. The front panel, however, is not entirely flat. It also has an angled panel where the sourceselect buttons reside. With the remote, youve got three, count em, three ways to pick sources.

digital over-the-air HD Radio. The front-panel USB jack accepts an iPod via the Apple-supplied adapter cable. There is no need for a cumbersome extra-cost dock. You can use the receivers onscreen display and remote to operate the iPod. There were a few surprises on the back panel. The HDMI output did not pass the onscreen menus; I used the component video output instead. Five of the seven sets of speaker terminals were like the collared binding posts you see on most receivers. However, the B speaker terminals were wire clips, which emphasizes the fact that they share amps with other channels. The 5.1-channel analog inputs only serve the center, sub, and surround, while the DVD analog inputs serve the front left and right channels. There are no S-video jacks but plenty of composite video. Also, the front-panel mini-jack for the MCACC microphone doubles as an audio input. All of these issues demonstrate the point that, if you want a good receiver at a low price, you live with compromises. The remote is simple but decent for a budget receiver. The control for master volume is a single horizontal rocker that measures a generous 1.4 inches wide. This simple and thoughtful touch made the remote a pleasure to use. Pioneer also made a modest effort to distinguish the other controls by shape. I counted nine distinct button shapes. Although the menu graphics are gray monochrome, its forgivable in a budget receiver. I hooked up the VSX-918V to a quintet of Paradigm Reference Studio 20 v.4 speakers. I set up the speakers to run full range, which is now my standard procedure for receiver reviews. Signal sources included a Pioneer Elite BDP-HD1 Blu-ray player. The player doesnt output a bitstream for Dolby TrueHD and other new surround

codecs, and the receiver has no onboard decoding for them. Still, they got along just ne communicating via high-resolution PCM, a maneuver that allows TrueHD
to live up to its potential. For DVDs, SACDs, and CDs, I used an Integra DPS-10.5 universal disc player. Vinyl ran on a Rega Planar 25 turntable with a Shure V97xE
cartridge and a NAD PP-1 phono preamp. Walk Hard: The Dewey Cox Story is a broad musical satire that lampoons Walk the Line, the Johnny Cash biopic. The VSX-918V beneted hugely from the Blu-ray and Dolby TrueHD treatment. Sure, the live ambience of John C. Reillys musical interludes was faked, but it still had an enveloping feel. Thats one thing Ive noticed about Tr ueH Ds ef fec t on musicit creates a betterdened soundeld. I was pleased to discover that even a modestly priced receiver like this one benefited from the next-gen codec. Lossless surround is for everyone, not just the afuent. My other two movie auditions were in old-style DTS. The setup menu of The Golden Compass noted: Optimized for home theater. No re-equalization required. This is probably true of most releases nowadays, but it was nice to be told. Roaring bears and whizzing witches abound in this semianimated fantasy. However, the soundtracks dominant element is an orchestral score that unceasingly comments on every moment of the action. All movie scores do this, but this one is especially tenacious, and it enhances the already imaginative storytelling. The recording of the orchestra some of it at the legendary Abbey Road Studiosis noticeably diffuse. Theres no attempt to concentrate it in the front channels. A s a result, every time I leaned to one side of
the sofa, I became aware of the string sound coming out of the surrounds. The receiver delivered dialogue beautifully and prevented the more aggressive effects from becoming strident. It was also revealing enough to let me split hairs about the orchestras deployment in the soundeld. If I hadnt already had these two rareed experiences, I might have attributed Aliens vs. Predator: Requiems more opaque sound to the receiver. Still, despite the aggressively roaring effects, I maintained the same volume setting throughout the movie, which indicates to me reasonably low distortion for a budget model. It was fun to discover in the end credits that the all-orchestral score had two titles, The Chopper and Grim Discovery.
Until this point, I knew that the VSX-918V wasnt bad. But was it actually good? A high-decibel session with Led Zeppelins debut LP provided the answeran emphatic yes. I played this title at moderate to loud volumes, and the receiver mustered the kind of buttery-smooth, well-focused sound that I associate with lowdistortion amps. Robert Plants vocal on Babe Im Gonna Leave You was imaged precisely between the left and right channels, even with the center shut down in stereo mode and my head weaving in and out of the sweet spot. With mounting satisfaction, I bumped the volume higher and higher with each track. Guitarist Jan Akkermans untitled albumhis fourth solo

recorddefines his distinctive fusion of rock, jazz, and classical elements with several longtime staples of his stage set. Akkerman recorded the album in 1977, with a string orchestra substituting for his guitar and keyboard synthesizers. The Pioneer brought out the oldfashioned monochromatic string recording, giving it a pleasing retro feel. With the speakers playing full range, the drum kit and congas sounded tight and had a fair amount of impact. This receiver is no substitute for a good outboard muscle amp, but it can still make drums sound like drums. The Garden of Cosmic Speculation is a riot of orchestral color, delivered via multichannel Telarc SACD. Its an exuberant antidote to the pofaced seriousness of much newly commissioned music. Composer Michael Gandol begins with allchannel birdsong and proceeds through a variety of styles, all of them accessible to non-academic listeners. He gleefully quotes music of every era from Gregorian chant to Bach to Stravinsky to Reich. The Pioneer kept pace with the works dynamics. I never needed to turn the volume down to avoid discomfort, or turn it up to catch low-level passages. I tried a few of Pioneers proprietary listening modes, most of which you can access via the remote or front-panel buttons. If youre using two speakers, Front Stage Surround Advance
provides a rich surround sound effect. The sound extends from a point between the front left and right speakers toward the center of the room. Two modes vary the faux-surround width. I tried both with Nick Drakes Five Leaves Left CD. The FSS Focus mode made it sound as though Drakes voice (beautifully recorded by John Wood) was in my head. The FSS Wide mode increased the effect. Overall, FSS produced a bigger sound but not a more focused one. A good recording can hold its own in plain stereo. Dialog Enhancement localizes dialog in the center channel, says the manual. I played the Drake CD in Dolby Pro Logic II Music mode, and this adjustment didnt affect the voice much. It did collapse the laterally wider guitar into the center channel, though. This might help if your center speaker is deficient and
you dont mind giving up some soundstage information. To enhance the ve amp channels, Virtual Surround Back simulates rear-surround speakers through your surrounds. I found it dispensable. Pioneer offers two enhancements for use with portable players. Sound Retriever attempts to compensate for artifacts of lossy audio compression. It seemed to increase the volume and thicken the lower midrange, but not in an unpleasant way. Automatic Level Control evens out the volume levels. It didnt do much for songs that were recorded at a steady level, but it did up the level for a quiet acoustic guitar track. I enjoyed using the Pioneer with the iPod USB connection. It sounded much better than when connected via analog mini-plug. If I owned this receiver, Id use this feature often.

The Pioneer VSX-918V is one very good-sounding budget receiver. No, it wont run power-pig speakers or decode Dolby TrueHD and DTS-HD Master Audio. But it will provide pleasingly clean power to speakers of appropriately high sensitivity. And it accepts Dolby TrueHD and DTS-HD Master Audio from your Blu-ray players built-in decoder via high-resolution PCM. Has Pioneer omitted a few features and connectivity options to keep the price down? Sure. But none of the omissions is fatal. This is the rare budget receiver that can provide pleasure with any kind of music or movie. Pair it with a good sat/sub set or stand-mount speakers from our Top Picks list on page 92, and have yourself some budget home theater fun. * Audio editor Mark Fleischmann is also the author of the annually updated book Practical Home Theater (www.quietriverpress.com).

NOTES : Parts marked by NSP are generally unavailable because they are not in our Master Spare Parts List. The mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation. When ordering resistors, first convert resistance values into code form as shown in the following examples. Ex. 1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J = 5%, and K = 10%). 560 = 1 = 561... RD1/4PU 1 J 47k = 3 = 473.. RD1/4PU 3 J 0.5 = R50... RN2H K 1 = 1R0... RS1P K Ex. 2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k = 1 = 5621..

7. GENERAL INFORMATION

7.1 DIAGNOSIS

7.1.1 Test Mode

When the remote-control code is received, forced analog inputs and 2-channel stereo mode are set for all functions. Speaker setting: All high volume, SW ON When this mode is entered, "SJG:ANA" will be displayed for 5 seconds.

12. STBY mode

" 0 " key
STBY mode is entered when the remote-control code is received.

6. FAN ON/OFF switch

The fan is turned on or off and rotates as follows: Low speed High speed Off.

" 4 " key

7.1.2 Protection of the Amplifier Line
1. Detection of abnormalities in DC circuits
This detection has priority over the overload detection and abnormality detection for the fan and thermistor.
If an abnormality has been detected, AMUTE is on, RELAY is off, and the "AMP ERR" display is flashing.
Does the abnormality continue for 5 seconds or more?

Power is turned off.

No (recovery)
The program restarts from the beginning.

2. Detection of overload

This detection has priority over the abnormality detection of the fan and thermistor. If an abnormality has been detected, AMUTE is on, RELAY is off, and the "OVERLOAD" display is flashing.
Power is turned off even if the unit has achieved recovery.
While the unit is recovering from the abnormality, the "OVERLOAD" display continues flashing.
7.1.3 Operation of the Fan-Control Line
1. Detection of the heat sink
The detection is carried out every other second by taking in the voltage of the thermistor at A/D (PORT 31).
2. According to the temperature detected, the following operation will be executed:
31 pin 0 to 0.1V 0.1V to 2.4V 2.6V to 2.8V 2.8V to 3.4V 3.4V to 4.1V 4.1V <to 122(60C) (70C)134 (75C)145 (90C)174 (115C)pin L L H L L L 25 pin L L L H H H 64,66,67 pin L H H H H L L H H H H L 19 pin
THRMO DCT Set voltage of A/D FAN START FAN MAX SP RELAY AMUTE

Display

"THDCT NG" flashes for 5 seconds.
"HEAT UP" flashes for 5 seconds at 20-sec intervals. "OVERHEAT" flashes.
If you wish to switch FAN START from "H" to "L" and FAN MAX from "L" to "H," first set FAN START to "L," then after 100 s, set FAN MAX to "H." While "OVERHEAT" is flashing, only the POWER key is functional.

3. FAN operation

Once the fan starts rotating, it continues to rotate at the same speed until the temperature falls to 65C. Once the fan starts rotating, it continues to rotate for at least 20 seconds even after the temperature falls to the above-mentioned level.

3. Speaker settings

According to the results of the detection, speaker settings are made as follows: Results of the Detections
Center SP Sub-woofer Connected Connected Connected Not connected Not connected Connected Not connected Not connected Front SP low high low high

Speaker Settings

Center SP Surround SP low low low low Not connected low Not connected low Subwoofer ON OFF ON OFF

4. User's settings

In Setup mode, more detailed speaker settings are available. Once the user's settings are made, those settings have priority. However, if the configuration of connected speakers has changed, then the detection results become valid and have priority over the user's settings until new user's settings are made.
