ote

If there is a strong electromagnetic wave product

nearby, an interference may be occurred.

(Ex : Micro wave oven)

Transmitter

Changing a channel of Transmitter

If there is a similar wireless product nearby, interference

may occur. In this case, change to other channel usingID/CHANNEL (ID./CH.) button of transmitter.

Press the ID/CHANNEL (ID./CH.) button for less

than about 3 seconds.

ote

The wireless speakers may not received the changed channel of

transmitter. In this case set the ID as below.

Setting a ID of Transmitter

When you connect the wireless speaker for the first

time, the blue and red LED indicator of wireless speakerblinks in turn and then the ID will be set automatically.

If an interference is occurred or you use a new wireless

speaker, set the ID.

1. Press the ID/CHANNEL (ID./CH.) button for more

than about 3 seconds.

The blue LED indicator blinks.

2. Turn the transmitter and wireless speaker off and

then turn it on.

Assembling and Connecting to

the Speakers

The front and rear speakers are detached from the

speaker stands. Connect the speaker cords and assem-

ble the front and rear speakers from speaker stands as

illustrated.

Connect the speaker cords to the appropriate termi-

nals on the bottom of each front and rear speaker.After connecting the speaker cords to the appropriateterminals on the bottom of each front and rear speak-er and attach the front and rear speakers to the

speaker stands.

ote

You cannot detach the speaker from the stand after assem-

bling the front and rear speakers.

Speaker Connections

Connect the speakers to the front (right, left) or center speaker connectors.

Connect the subwoofer to the woofer connector.

Connect the power cord of the wireless speaker to the outlet.

Connect the DC IN connector of transmitter and the transmitter connector of rear panel with the DC power cable.

Connect the SOUND SIGNAL connector of transmitter and the rear (right, left) speaker connector of rear panelwith 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 through10m 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 showslower EMI and higher power conversion efficiency com-pared to conventional hard-switched converter with afixed switching frequency. Therefore, a QRC is wellsuited for noise-sensitive applications, such as color TVand audio. Each product in the FSCQ-Series contains anintegrated Pulse Width Modulation (PWM) controller anda SenseFET, and is specifically designed for quasi-resonant off-line Switch Mode Power Supplies (SMPS)with minimal external components. The PWM controllerincludes an integrated fixed frequency oscillator, under volt-age lockout, leading edge blanking (LEB), optimized gatedriver, internal soft start, temperature-compensated pre-cise current sources for a loop compensation, and selfprotection circuitry. Compared with a discrete MOSFETand PWM controller solution, the FSCQ-Series canreduce total cost, component count, size, and weight, whilesimultaneously increasing efficiency, productivity, and sys-tem reliability. These devices provide a basic platform thatis well suited for cost-effective designs of quasi-resonantswitching flyback converters.

Pin Configuration

Figure 3. Pin Configuration (Top View)

Pin Definitions

Pin Number Pin Name Pin Function Description

1 Drain High voltage power SenseFET drain connection.

2 GND This pin is the control ground and the SenseFET source.

3 Vcc This pin is the positive supply input. This pin provides internal operating current for both start-up and steady-state operation.

4 Vfb 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.

Figure 2. Block Diagram

Figure 3. Channel Signal Flow Diagram through the Digital Core

3.1 EQ ProcessingTwo 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 basedon various configuration parameter settings.

The entire EQ block can be bypassed for all channels simulatneously by setting the DSPB bit to '1'. Andthe CxEQBP bits can be used to bypass the EQ functionality on a per channel basis. Figure below showsthe internal signal flow through the EQ block.
