1 The crosstalk between TAPE and AUX is measured with a 5.1k external resistor connected to AUXIN1 (Pin 5). In this condition, the crosstalk is approximately -67dB due to the signal leak from MSLPF (Pin 6). In order to improve the crosstalk between TAPE and AUX, AUXIN1 pin should be driven with a low impedance.

Fig. 3. Playback equalizer amplifier block diagram
Fig. 4. Playback equalizer amplifier frequency response
The CXA2509AQ achieves the frequency response of Fig.4 with the circuit configuration shown in Fig. 3. Two systems (FORWARD and REVERSE) of playback head input are provided for each channel. The FORWARD input pin is selected when DRSW (Pin 19) is Low; REVERSE is selected when DRSW is High. The playback equalizer amplifier frequency response can be set in two levels. When TAPESW (Pin 18) is Low, SW2 shown in Fig. 3 is turned OFF; when TAPESW is High, SW2 is turned ON. The external resistance R1 should be adjusted to adjust the playback equalizer amplifier gain. The playback equalizer amplifier frequency response is all determined by the external resistance and capacitance, and it can be obtained with the following equation. G (s) = 1 + {s * C1 * (R1 * R2 + R2 * Rx + Rx * R1) / (R1 + R2)} R1 + R2 * (s = j) 1 + s * C1 * (R2 + Rx) R1
Where, Rx = R3 when TAPESW pin = Low; Rx = R3//R4 when TAPESW pin = High Using the above equation, G1 in Fig. 3 and low-frequency time constant (T1) and high-frequency time constants (T2 and T3) are as follows: G1 = 20log R1 + R2 R1
T1 = C1 * (R2 + Rx) T2, T3 = C1 * (R1 * R2 + R2 * Rx + Rx * R1) R1 + R2

Fig. 5. Music sensor block diagram The signal input from TAPEIN is added and amplified by AMP1. This signal is then input to the LPF (R4 and C1). The LPF cut-off frequency can be adjusted by connecting the external capacitance to MSLPF pin. The cut-off frequency is approximately 23kHz when MSLPF pin is left open. The detection level and HPF cut-off frequency are determined with the external resistance and capacitance connected to G1FB or G2FB at AMP2, and the signal is converted to a current. The signal is full-wave rectified and is converted to a voltage by the internal resistance R5. The full-wave rectified signal is smoothed. The internal resistance (R6) and external capacitance (C4) determine the smoothing response time. The recovery time is determined by the external resistance (R10) and capacitance (C4). The AMP3 comparator detects whether the smoothed signal is greater or smaller than the comparator threshold. The comparator has approximately 2dB hysteresis. The table below shows the example of the constant and characteristics for the external resistance and capacitance connected to G1FB and G2FB.

Notes on Operation 1. Playback equalizer amplifier All playback equalizer amplifier characteristics are determined by the external constants. Use the parts which satisfies the accuracy required for the playback equalizer amplifier. 2. Music sensor The current on DIREF (Pin 25), and the resistance and capacitance connected to G2FB (Pin 10) and G1FB (Pin 11) determine the detection level and the HPF cut-off frequency. The response time is determined by the resistance and capacitance connected to MSTC (Pin 12). Use the parts which satisfies the accuracy required for the music sensor.
