RSX-1057

Surround Sound Receiver

An important note about power specifications:

When is 75 watts really 75 watts? In the days of two-chan-

nel audio, it was pretty easy to determine the power of an

amplifier because everyone had to play by the same rules. All

manufacturers were forced to use the following criteria to de-

termine power as mandated by the FTC. All of the amplifier’s

channels must be driven at 8 ohms with a frequency response

of 20 Hz to 20 kHz. The FTC does not have a rule enforcing

the measurement of multi-channel amplifiers.

This test produced a result called RMS (Root Mean Square),

or the continuous average output of the amplifier. This is still

the only proper way to test an amplifier’s capabilities. Today’s

multi-channel receivers and power amplifiers are often having

their power rated (watts per channel) by driving one channel at

1 kHz. This formula will never tell you how that amplifier will

perform under a real-world load because the sound humans

can hear is located across the entire bandwidth of 20 Hz to

20 kHz.

Rotel is an audiophile company and is proud to display the

actual power rating of all channels driven at 8 ohms with a fre-

quency response of 20 Hz to 20 kHz. This is the only way to

show what actual power will be available during real-world use.

Be careful of what appears to be exceptional power ratings for

a given price range and read the specifications carefully. For

mance, read pages four and five in our 2005 - 2006 Product

Surround Sound Receiver

From a quick glance at its specifications, Rotel’s new RSX-

1057 surround sound receiver might seem like just another

entry in this very crowded component category. Yet, the

RSX-1057 distinguishes itself from the competition during

actual use with an overbuilt power supply that delivers the

extreme voltage and current required during those explosive

soundtracks so prevalent in today’s movies.

The high current amplifier section puts a full 75 watts RMS

per channel at your sonic disposal (that’s with all five chan-

nels driven simultaneously from 20 Hz to 20 kHz with no

more than 0.05% THD!). In the real world, this is far more

power than you’ll find in other products that provide only two-

channel ratings. Of course, superb power supply design helps

here as does careful par ts evaluation and selection. But,

that’s simply part of Rotel’s Balanced Design heritage.

Are you concerned about future audio/video needs? The

RSX-1057 is HDMI ready now with two HDMI inputs and one

HDMI output (version 1.1) to connect your A/V components

to the latest generation video displays with 1080P capability.

Will you be moving your system to a larger environment, or

considering an eventual move to full 7.1 surround capability?

The RSX-1057 features an option that provides for the simple

addition of a two-channel amplifier to expand your home the-

ater options to full 7.1 should you desire it.

Rotel hasn’t forgotten convenience either. The RSX-1057

provides analog and digital connections for up to seven addi-

tional components. The RSX-1057 even allows you to re-label

inputs, assign inputs, perform advanced bass management

and equalize channels.

Advanced microprocessors from Cr ystal Semiconductor

handle Dolby Digital, Dolby Digital EX, DTS, DTS ES Discrete

and Matrix, DTS 24/96, DTS Neo:6 and Dolby Pro Logic

II X decoding and provide several music modes for your

enjoyment, too. Three component inputs and internal video

transcoding let you see the best picture possible regardless

of your source.

The RSX-1057 is also for custom installations. There’s an

RS-232 interface, multi-room, multi-source with composite

video, three assignable 12-volt trigger outputs, discrete on/

off remote control command codes, rear panel IR inputs, and

a detachable AC power cord. A fully programmable remote

control is standard.
