with the SOUND SIGNAL cable.
Set the distance between the transmitter and wireless
speaker (right, left)
within 10m.
Notes:
Optimum performance
can be
implemented only
when the transmitter and the wireless
speaker
within distance of 2m
through
10m is used since communication failure
may
occur if
closely approaching
distance between them.
Be sure to match the
speaker
cable to the
appropriate
terminal on the
components:
+ to + and
--
to --. If the cables are
reversed,
the sound will be distorted and will lack base.
Do not remove the front cover of
supplied speaker.
It takes a few seconds
(and may
take
longer)
for the transmitter and wireless
speaker (left, right)
to communicate with each
other.
When the main set is turned
off,
the transmitter is also turned off
automatically
and the wireless
speaker
is in
standby
mode
(red
LED
indicator).
If the wireless
speaker
is turned
off,
the wireless
speaker
will not function.

Description
A Quasi-Resonant Converter (QRC) typically shows
lower EMI and higher power conversion efficiency com-
pared to conventional hard-switched converter with a
fixed switching frequency. Therefore, a QRC is well
suited for noise-sensitive applications, such as color TV
and audio. Each product in the FSCQ-Series contains an
integrated Pulse Width Modulation (PWM) controller and
a SenseFET, and is specifically designed for quasi-
resonant off-line Switch Mode Power Supplies (SMPS)
with minimal external components. The PWM controller
includes an integrated fixed frequency oscillator, under volt-
age lockout, leading edge blanking (LEB), optimized gate
driver, internal soft start, temperature-compensated pre-
cise current sources for a loop compensation, and self
protection circuitry. Compared with a discrete MOSFET
and PWM controller solution, the FSCQ-Series can
reduce total cost, component count, size, and weight, while
simultaneously increasing efficiency, productivity, and sys-
tem reliability.These devices provide a basic platform that
is well suited for cost-effective designs of quasi-resonant
switching flyback converters.

Pin Number Pin Name Pin Function Description
1Drain High voltage power SenseFET drain connection.
2 GND This pin is the control ground and the SenseFET source.
3Vcc This pin is the positive supply input.This pin provides internal operating current for
both start-up and steady-state operation.
4Vfb This pin is internally connected to the inverting input of the PWM comparator.
The collector of an optocoupler is typically tied to this pin. For stable operation,
a capacitor should be placed between this pin and GND. If the voltage of this
pin reaches 7.5V, the over load protection triggers , which results in the FPS
shutting down.
5 Sync This pin is internally connected to the sync detect comparator for quasi-resonant
switching. In normal quasi-resonant operation, the threshold of the sync
comparator is 4.6V/2.6V.Whereas, the sync threshold is changed to 3.0V/1.8V
in an extended quasi-resonant operation.

2 DESCRIPTION
The STA328 is an integrated solution of digital au-
dio processing, digital amplifier control, and DDX-
Power Output Stage, thereby creating a high-pow-
er single-chip DDX® solution comprising of high-
quality, high-efficiency, all digital amplification.
The STA328 power section consists of four inde-
pendent half-bridges. These can be configured via
digital control to operate in different modes. 2.1
channels can be provided by two half-bridges and
a single full-bridge, providing up to 2x40W +
1x80W of power output. 2 Channels can be provid-
ed by two full-bridges, providing up to 2x80W of
power. The IC can also be configured as a single
paralelled full-bridge capable of high-current oper-
ation and 1x160W output.
Also provided in the STA328 are a full assortment
of digital processing features. This includes up to
4 programmable 28-bit biquads (EQ) per channel,

Figure 2. Block Diagram
Figure 3. Channel Signal Flow Diagram through the Digital Core
3.1 EQ Processing
Two channels of input data (re-sampled if necessary) at 96 kHz are provided to the EQ processing block.
In this block, upto 4 user-defined Biquads can be appplied to each of the two channels.
Pre-scaling, dc-blocking high-pass, de-emphasis, bass, and tone control filters can also be applied based
on various configuration parameter settings.
The entire EQ block can be bypassed for all channels simulatneously by setting the DSPB bit to '1'. And
the CxEQBP bits can be used to bypass the EQ functionality on a per channel basis. Figure below shows
the internal signal flow through the EQ block.
