Introduction
The term "Mass Market Receiver" usually invokes images of
something relatively inexpensive, with specs that are not very good.
However, there have always been expensive receivers one
could choose if one wanted to.
I remember when surround sound first became a buzzword,
and I looked at a few in our local stores.
In those days, the new receivers had five channels, but
only Dolby Surround decoding, which then changed to Pro Logic. The two rear
channels were mono, the rear channel amplifiers were actually just
amplifiers on a chip, and the speaker binding posts were often of the spring
clip variety.
The one I wanted was $2,000. Discrete amplifiers in all
five channels and real binding posts for all channels. The power output was
75 watts to the front left and right, 50 watts to the center, and 35 watts
to the rear left and right. It still only had Pro Logic decoding with its
mono rear surround, but it had a bunch of "Modes" that simulated cathedrals,
stadiums, and jazz clubs. It was big and heavy, as most of the new
technology had not been incorporated in single chips yet. I was enthralled,
but could not afford the $2,000 price tag.
Now, even the <$500 receivers have discrete amplifiers
boasting 100 watts per channel, real binding posts, and will decode
everything from Dolby Digital to DTS. Many of them are built in China, and
are actually reasonable quality.
So, when a receiver now comes along that costs $7,000, is
there any motivation to select that over one that costs $1,000, when the
features seem to be the same?
The Lexicon RV-8
Lexicon has been around a long time, and has always stood
for high quality. When someone said they had a Lexicon, it usually meant a
processor, as they built one of the early surround decoders.
These days, they build preamp/processors, like the MC-12,
as well as power amplifiers, receivers like the RV-8, and DVD players
like the RT-20.
All of the Lexicon products cost much more than most
other brands. So, what do you get for your money?
Is it a proprietary design? No, all the manufacturers
have their own special designs and processing techniques.
To me, it is in parts quality, which includes the
materials they are made of along with the tolerance, and the power supply. I
know that sounds simplistic, but it works.
An electronic circuit consists of capacitors, inductors,
resistors, transistors, op amps, switches, and the conductors that connect
them all. The circuit design depends on those components being certain
values (farads, henries, and ohms). If a component's value is off by 5%,
that can cause the signal to deteriorate. If a number of components are off
by 5%, the signal can really deteriorate. Looking at a parts catalog, you
will find that they are offered at various tolerances. Some are 5%, and
others are 1%. The lower that tolerance number, the better the part, but the
higher the cost. When you add up the cost of all the hundreds of parts, the
sum total can be really high, and you multiply that x 4 to come up with what
they have to charge on the dealer shelves.
So, basically, the $199 receiver may have similar "specs"
to the $1,000 receiver, but its parts quality is lower, so the ultimate
performance is not so good.
And, the power supply. This is probably the most
expensive part of any receiver. Big, high quality capacitors, along with a
heavy transformer, really drive up the price. The inexpensive receivers that
tout 100 watts per channel output don't have big caps and transformers, so
that 100 watt output will only work for a few milliseconds, and since action
film special effects usually last much longer than a few milliseconds, the
result is clipping, which sounds like mush.
The chassis is much heavier with this kind of product,
which increases cost. Lastly, since high performance products - with their
high price - are sold in smaller quantities, this adds an ironic number to
the final selling price. They have to do this to make up for the R&D that
went into designing it.
So, obviously, I am building up to stating that the
Lexicon RV-8 has top notch parts and a big power supply (along with a
massive chassis). That is what
constitutes a first rate receiver. I would not call it a mass market
receiver, because that masses can't afford one. That $2,000 receiver I oggled way back when was not mass market either. Too expensive for most of
us, including me at the time.
The Lexicon RV-8 is in a category we should call High
Performance Receivers. High-end is the usual term, but that sounds a bit
snooty. High Performance tells you what it is capable of, not the class of
people who can buy it. Much more descriptive.

Specifically . . .
The RV-8 is a 7.1 receiver. It has seven power amplifiers
rated at 140 watts RMS per channel, all channels driven simultaneously. It
weighs 65 pounds, which speaks to that heavy power supply.
The front panel looks more complicated than most, but it
is actually not. The buttons that are usually hidden by a fold down door at
the bottom in other receivers, are across the entire face of the RV-8.
In the photo, you can see four vertical sections. From
the left are the Main, then Zone 2, followed by Zone 3, and the Tuner. So,
you don't have to open any other panel doors. You just select what you want
across the main panel face. The Main, Zone 2, and Zone 3 panels all allow
you to select the input for that section. The Tuner panel lets you select
the station.
At the bottom are seven LEDs that tell you all seven
power amplifier channels are operating. If one goes out, time to see a
service technician.
The fact that there are two zones besides the main one,
is indicative that the RV-8 is designed to serve your entire house A/V
needs. That is the trend in the big receivers these days. So, you can watch
a movie in the den, and have music in the kitchen as well as on the patio,
all at the same time, all served by the RV-8.
The rear panel has myriad inputs and outputs, like most
modern receivers.

The left and right ends are taken up by the seven sets of
power amplifier output binding posts, four on the left and three on the
right.
There are five composite and S-Video, and three sets of
component video inputs along the top. Underneath that are eight stereo pairs
of analog audio inputs, and one set of audio pre-outs for all channels. Some
of the stereo analog audio pairs can be configured for a second set of
pre-outs if you need two sets.
For outputs, there are two S-Video and one component
video set for the main zone, two composite and two S-Video, along with two
stereo analog audio outputs for Zone 2, and one composite video with one
pair of stereo analog audio outputs for Zone 3.
Digital audio inputs include four RCA and four Toslink.
There are no digital video inputs (DVI or HDMI), but I suspect the blank
panel at the bottom might be used for this in a future upgrade. The two
microphone inputs, also at the bottom, are listed for future use, I imagine
for their Auto EQ functions that they have on the MC-12 Version IV.
The remote control is a standard one now included with a
number of different manufacturers.
It is a universal remote, with backlighting.
To access the RV-8, you simply press the right arrow
button on the round dial in the middle.
This brings you to the Main menu, which has Mode Adjust,
Audio Controls, Tuner Presets, and Setup as submenus.
Using the arrows, you scroll through the selections,
which are shown on the RV-8 front panel, or on the OSD, which is is fed from
one of the S-Video outputs marked on the rear panel.
The Setup menu has Inputs, Speakers, I/O Configuration,
Displays, Volume Controls, Trigger, Tuner, and Lock Options.
The Inputs menu lets you assign which input jack should
be connected to DVD 1, DVD 2, CD, TV, etc.
So, for example, in my tests, I assigned stereo analog
audio pair 1 to the DVD 1 input, and Toslink digital input 1 to DVD 2. I
connected the stereo analog audio outputs of a Yamaha Universal DVD Player
to analog audio pair 1 and the Toslink output from the same player to
Toslink 1. This allowed me to compare the decoding of the DVD player to the
decoding done by the RV-8, in A/B form by just switching inputs during music
playing.
Speaker set-up allows complete small increment time alignment and small
increment volume control for each channel.
The I/O Configuration lets you assign some of the analog inputs to either
stereo or 5.1 such as would be used with DVD-A and SACD. You can configure
two complete sets of 5.1 analog inputs and still have several analog stereo
pair inputs for other sources.
Volume Controls have such features as individual input level settings for each
input, so that you don't get unpleasant surprises when switching inputs.
Most receivers have an AM/FM tuner, and the RV-8 has a good one, with great
flexibility in setting up your favorite stations, Region (USA, Europe,
Japan), Scan Sensitivity (so you won't waste time scanning through weak
stations).
The RV-8 has a ton of options, so once you have everything the way you like
it, you can lock it all down so no one can accidentally change the
configuration.
