Notes to the characteristics
1. Operation with minimum of 12 dB headroom; system remains functional to 7 V.
2. Attenuation between pins 1 and 3 is 3,5 dB (MPX-filter).
Playback input sensitivity is 45 mV if a switchable MPX-low pass filter is used in playback mode (pins 2 and 3
short-circuited).
3. System headroom is determined by the line output channel in use.
For low supply voltages line output 2 (pin 6) will saturate at high signal levels. Headroom for line output 1 (pin 5)
tracks with record output (pin 21).
4. The equation for REC/PB switch input voltage is:
REC: V24-27 > 0,55 VCC − VBE + 1,5 V,
PB: V24-27 < 0,45 VCC − VBE −1,5 V.
5. The equation for C/B/OFF mode switch input voltage is:
OFF: V25-27 < 0,38 VCC − VBE − 1 V,
B: 0,45 VCC < V25-27 < 0,55 VCC (external voltage),
B: 0,5 VCC (switch in open position),
C: V25-27 > 0,75 VCC − VBE + 1 V.
The voltage drop across the external time constant resistor must be taken in to account.
6. TPL is Test Point Level.
