Sound Processors for Home Theater Systems

6.1ch

Sound Processor

BD3816K1,BD3817KS

No.10081EAT06

●Description

The BD3816K1 and BD3817KS are 6.1ch sound processors. Functions required for applications, such as AV receivers and

home theater systems, are integrated into a single chip. A wide dynamic range of 132dB is achieved by utilizing the

BiCMOS process.

●Features

1) Dynamic range: 132dB (Volume Direct Mode, VOL=MUTE, IHF-A)

2) Independent 7 channels for Master Volume (0 to -95 dB, MUTE 1dB/Step)

3) Supporting 2^ndroom entertainment/2^ndsource recording.

4) Low current consumption design achieved by adopting the Bi-CMOS process.

5) Maximum output voltage: 4.2Vrms (VCC=7V, VEE=-7V, RL=10k).

6) Built-in Input Gain Amp useful for amplifying input signals (0-7dB, 1dB/Step).

7) Built-in Output Gain Amp useful for adjusting output signal voltages (0-17dB, 1dB/Step)

8) Built-in mixing circuit for distributing the output signals from Center and Subwoofer channel to Front R/L channels

(0, -3, -4.5dB).

9) 2ch Volume control BD3812F or 6ch Function Switch BD3843FS can be controlled simultaneously

by the serial control bus.

10) REC A output terminal with a REC input/output switch useful for monitoring Equalizer Amp.

(For BD3816K1, available as an input function of the seventh line.)

11) Output mute controlled by either serial data or an external control terminal.

12) 2-wire serial control (For both 3.3V and 5V)

●Applications

AV receivers, home theater systems, and mini-audio systems.

●Line up matrix
