1,Brief story : Q series was designed to
meet small scale sound system.adopted high efficient Switching mode
power for Class D amplifier modules. Features very compact design
and light weight.Combined with 2 models Q504(4*500W) and
Q502(2*500W) that well matched conference or school sound system
with low budget.2,Feutures:1,Class D 1U rackable design2, Capable

areZhongshan tinboo audio electronics co,.limited(Brand in
Audiopeak,call us audiopeak for short),Located in ZHONGSHAN
CN, was founded in Aug 2009 and is dedicated to providing
"one stop supply" precision amplifier system to ODM and OEM
clients. audiopeak products lines include: Analog
amplifier,Digital amplifier,Self-power module, DSP amplifiers . Now
audiopeak is One of the most professional manufacturers of pro
audio...WHAT we doInnovation By DesignAt AUDIOPEAK, we are driven
by a singular vision - produce great products. It may sound simple,
but it's at the forefront of everything we do.We always strive for
products that ARE easy to install and a pleasure to use. The quest
to be the best is a never ending and sometimes exhaustive road, But
it's a pillar of our success.Battle TestedAll of our products are
"battle tested."We firmly believe that to deliver a great product
one must spend a lot of time not just perfecting the design but
actually using the product. That is why we put a great deal of time
and effort into research, design and testing.Custom MadeOut of the
thousands of amplifiers to choose from, how many are custom
made just for you?At Audiopeak electronics, a big portion of our
business is based on designing & manufacturing custom made products
for both outdoor and indoor AMPLIFICATION.It's what we do and it's
a big part of who we are. How do I match my speakers to
my power amp?A general rule for choosing an amplifier is to select
an amp that provides 1.5-2 times the continuous power rating
of your speaker. This will ensure the speaker has enough power
while leaving yourself 3 dB of headroom. How do STEREO,
PARALLEL, and BRIDGE modes operate?STEREO: Each channel operates
independently. Input signal and attenuator are also separated
between each channel.PARALLEL: Input signal is connected to only a
single channel, and the same output signals are obtained from two
adjacent channels. Attenuator operates independently.BRIDGE: Two
channels of power amp output work as a single channel with doubled
output. Only a single attenuator operates. The voltage gain will be
increased by 6dB, and the minimum load impedance will be doubled.
For details on connecting the speaker output, please refer to the
manual that came with each power amp. What is rated output
power?Rated output power is the RMS (root mean square) or effective
value of electric power that can be delivered continuously for
several ten seconds to few minutes. The unit is W (Watt).It is not
a value that can be output continuously for a long period, but it
would not matter in a practical operation because music signal and
voice speech signal are generally not constant in level. When a
signal like continuous sine wave is continuously driven at the
rated output, the thermal protection circuit will be activated,
which will reduce the output power to around 1/8 (-9dB). What
is input sensitivity?it is the required input signal level to
obtain the rated output when attenuator is in its maximum
(generally 0dB). It also means the output signal will be clipped if
a signal larger than the input sensitivity is being input with the
attenuator at maximum. When the voltage gains are the same, the
larger output model is, the larger its input sensitivity is, too.If
the load impedance is halved, the output power will be almost
doubled since the voltage gain is constant. In this case, however,
the input sensitivity will be a little smaller because the actual
rated outp
