ADE-207-198B (Z)

3rd Edition

Jun. 1999

Description

HA12206NT is silicon monolithic bipolar IC providing music sensor system, ALC, REC equalizer system and each electronic control switch in one chip.

Functions

• REC equalizer × 2 channel

• Line Amp. × 2 channel

• ALC (Automatic Level Control)

• MS (Music Sensor)

• Each electronic control switch to change REC equalizer, bias, etc.

• REC mute

Features

• REC equalizer is very small number of extern al parts, built-in 2 types of frequency characteristics.

• Correspondence with normal position (TYPE I) / high position (TYPE II).

• TYPE I / TYPE II and PB equalizer fully electronic control switching built- in.

• Controllable from direct micro-computer output.

• Available to reduce substrate-area because of high integration and small external parts.

Operating Mode Control

HA12206NT provides fully electronic switching circuits. And each operating mode control is controlled by parallel data (DC voltage).

Table 2 shows the control voltage of each control input pin.

PB Equalizer

By switching logical input level of pin17 (for Ain) or pin18 (for Bin), you can equalize corresponding to tape position at play back mode.

Frequency characteristics of high position (TYPE II) depends on capacitor C1 on the block diagram figure.

Figure 3 Frequency Characteristic of MS AMP

Occasion of the external component of figure 2, f1 is 430Hz and f2 is 1.1kHz. As the MS sensitivity is prescribed at 5kHz, this stage’s gain is 7.9dB. But in only one-sided channel input case, this gain is considered as –6dB down, because the other channel input pin is imaginary earth. That is, the gain from RPOUT to MSDET is 1.86dB. As the detection sensitivity at MSDET is fixed 130mVrms, the sensitivity at RPOUT (8 pin or 23 pin) is calculated by the following formula.

130mV

10 ^

1.86 20

= 105mV

Because of RPOUT=580mVrms=0dB, therefore, the MS sensitivity becomes –14.8dB. That is the detection level.

Time Constant of Detection Figure 4 (1) generally shows that detection time is in proportion to value of capacitor C16. But, with

Like the figure 4 (2), Recovery time is variably possible by value of resistor R6. But Attack time gets about fixed value. Attack time has dependence by input level. When a large signal is inputted, Attack time is short tendency.

Music Sensor Output (MSOUT) Because MS out pin is connected to the collector of NPN type directly, it is requested to use pull up resistor

(RL=10k to 22kΩ) Output level is “High” sensing no signal. And output level is “Low” sensing signal. Please take notice of MS Low level voltage (GND+0.9V). The connected supply voltage must be less than V

Automatic Level Control (ALC)

ALC is the input decay rate variable system. It has internal variable resistors of pin6 (pin25) by RECOUT signal that is inputted to pin8 (pin23). The operation is similitude to MS, detected by pin15. The signal input pin is pin5 (pin26). Resistor R1, R2 and capacitor C2, external components, for the input circuit are commended as figure 6. These are requested to use value of the block diagram figure for performance maintenance of S/N, T.H.D. etc. Figure 5 shows the relation with R1 front REC IN point and RPOUT. ALC operation level is 775mVrms {standard level (580mVrms) +2.5dB}. And it is designed to operate from 0dB to +15dB as 775mVrms=0dB. Adopted maximum value circuit, ALC is operated by a large channel of a signal. ALC on/off is linked with REC mu te. When REC mute is on, ALC is off.

REC-Equalizer

REC mute is located at input-part of REC-equalizer. Therefore it has realized low pop noise. But because there is deference DC offset at the each mode of REC-equalizer, it is necessary for a coupling capacitor between EQOUT pin and recording head.
