1. SAFETY PRECAUTIONS

PRECAUTIONS:

1. Power supply: This speaker can only use the type of power supply as specified in the instruction manual or marked on the master speaker.
2.Power line protection: Make sure to avoid power line being trampled, pulled or squeezed by heavy objects. In particular, be sure to hold the plug when pulling the power line from the socket. Never pull on the power line. besides, keep the power line away from hot objects.

6. Removing cabinet: In case of speaker failure or problems due to improper use, don't dismantle the unit to repair or check by yourself. Please turn off the power and use after checked by specialists to avoid causing personal accident.

3.Cord polarity: The speaker cord must be correctly connected as per marking on the function panel."+" and "-" Must have correct polarity so maximize the inherent quality of the speaker. Otherwise, normal function and output will be affected.
4. Ventilation: This speaker has good adaptability to the environment, but pay attention to the environmental ventilation during long periods of work.
5. Water and moisture: Keep the sound box 8. away from rain, water spray, water splash and wet environment, such as bath, kitchen, water basin, washing basin, damp basement, swimming pool, etc.

7. Appearance cleaning: Don't use volatile solutions to clean the speaker to avoid damaging the appearance.

8. Please cut off the power: If you don't use the sound system for a long time, please remove the cable wire or disconnect the power to ensure the speaker safety and household safety.

HEF4053B

MSI

Triple 2-channel analogue multiplexer/demultiplexer

DESCRIPTION

The HEF4053B is a triple 2-channel analogue multiplexer/demultiplexer with a common enable input (Ē). Each multiplexer/demultiplexer has two independent inputs/outputs (Y_O and Y₁), a common input/output (Z), and select inputs (S_O). Each also contains two-bidirectional analogue switches, each with one side connected to an independent input/output (Y_O and Y₁) and the other side connected to a common input/output (Z).

With E LOW, one of the two switches is selected (low impedance ON-state) by S_D. With E HIGH, all switches are in the high impedance OFF-state, independent of S_A to S_D.

V_DD and V_SS are the supply voltage connections for the digital control inputs (S_A to S_C and E). The V_DD to V_SS range is 3 to 15 V. The analogue inputs/outputs (Y_O, Y₁ and Z) can swing between V_DD as a positive limit and V_EE as a negative limit. V_DD-V_EE may not exceed 15 V.

For operation as a digital multiplexer/demultiplexer, V_EE is connected to V_SS (typically ground).

1. To avoid drawing V_DD current out of terminal Z, when switch current flows into terminals Y, the voltage drop across the bidirectional switch must not exceed 0,4 V. If the switch current flows into terminal Z, no VDD current will flow out of terminals Y, in this case there is no limit for the voltage drop across the switch, but the voltages at Y and Z may not exceed V_DD or V_EE.

M1875 20W Audlo Power Amplifie

LM1875 20W Audio Power Amplifier

General Description

The LM 1875 is a monolithic power amplifier offering very low distortion and high quality performance for consumer audio applications.

The LM1875 delivers 20 watts into a 40 or 80 load on ±25V supplies. Using an 80 load and ±20V supplies, over 30 watts of power may be delivered. The amplifier is designed to operate with a minimum of external components. Device overload protection consists of both internal current limit and thermal shutdown.

The LM 1875 design takes advantage of advanced drout techniques and processing to achieve extremely low distortion levels even at high output power levels. Other outstanding features induce high gain, fast slew rate and a wide power bandwidth, large output voltage swing, high current capability, and a very wide supply range. The amplifier is internally compensated and stable for gains of 10 or greater.

βlote 2 . Assumes the use of a heat sink having a thermal resistance of 1°CAV and no insulator with an ambient temperature of 25°C. Because the output limiting directivity has a negative temperature coefficient, the maximum output power delivered to a 4Ω load may be slightly reduced when the tab temperature exceeds 55°C.

Functional Description

Transmission Code

The transmission code consists of a leader code, 16-bits custom codes, and 8- bits data codes. The inverse code of the data code is also sent simultaneously. The following diagram shows this one frame construction.

The leader codes consist of a 9 ms carrier waveform followed by a 4.5 ms OFF waveform. It is used as the leader for the following code. Thus, when reception is configured by a microcomputer, the time relationship between the reception detection and other processes can be managed efficiently. The code uses the PPM (Pulse Position Modulation) Method, with "1" and "0" differentiated by the time between pulses. Each code consists of 8 bits, and simultaneous transmission of the inverse code allows configuration of a system with an extremely low error rate.
