Page 5: Control Functions
CONTROL FUNCTIONS: BALANCED MICROPHONE INPUT XLR, low impedance (2.2 k Ohm), balanced microphone input. Pin 2 is the positive and pin 3 – the negative phase. PAD SWITCH This pad switch attenuates the signal (reduces the sensitivity) on the microphone input with 20 dB. - Page 6 LINE GAIN This Gain control varies the gain of the Line input. The gain ranges from Off, 0 dB (center detent), to +10 dB. LOW EQ A shelving type of active tone control that varies the frequency range below 80 Hz by +/-15 dB. LOW MID A band pass (boost/cut) type of active tone control that varies the signals within the selected low-frequency range with +/-15 dB.
- Page 7 ST LED This bicolor LED is off when the SmarTube ™ circuit is off-line (full CCW position (20) - Off). It starts blinking in green as the amount of tube-effect increases until it reaches nominal level - around the center detent position (N) of 20. The color of this LED gradually turns red as the addition of tube-effect increases and gets closer to maximum (MAX).
- Page 8 LINE INPUT: This is a 1/4" (TRS) balanced line-level, high-impedance (200 k Ohm) input for high and instrument level signals. The tip is the positive phase and the ring – the negative. An unbalanced, (instrument), 1/4" (TS) connection can also be made at this input. This connector duplicates the front panel Line input.
