PM3500M Input Modul


1. +48V phantom power switch

2. GAIN: This rotary knob provides 50dB of continuously variable adjustment for the input preamplifier gain. A setting of -70 (full clockwise rotation) provides maximum gain for low-level mic inputs, whereas a setting of -20 provides minimum gain for low-level line inputs or "hot" mics. These settings provide 30dB less overall gain when the 30dB pad [5] is engaged.

3. 30dB (pad switch)

4. PHASE SWITCH

5. EQUALIZER SECTION: The input channel equalizer is devided into four bands, each with sweepable filter frequencies. The high and low bands may be switched between peaking and shelving types, and the high-mid and low-mid are peaking. All bands have adjustable Q, providing fully parametric type equalization. The level (gain) is adjustable with 15dB of cut or boost in each band.

6. EQ SWITCH

7. INSERT: When this switch is engaged, any signal present at the channel's INSERT IN jack will replace the channel signal. The INSERT OUT jack is always "live" and is unaffected by this switch. The main use of this switch is to select or deselect any processing equipment connected to the INSERT jack.

8. HPF (switch and control): The HPF control sets the cutoff frequency of the filter from 20Hz(fully counter- clockwise) to 400Hz(fully-clockwise).

9. AUX SENDS 1 - 8 (AUX ON/OFF and Pre/Post switches, and level controls)

10. GROUP SEND ON/OFF and PRE switches and level controls 11. ST (stereo) controls

12. PEAK, NOMINAL and SIGNAL indicators

13. ON/EDIT switch and CHECK indicator: The ON/EDIT switch illuminates when active. When on, the channel's input is routed to the appropriate master group busses as determined by the Assign switches, the stereo buss (if selected) and any auxiliary busses.
The switch can also be used to edit the configuration of "scenes" prior to storing them into one of the 128 memories available.

14. VCA Group (1 - 8)

15. Fader

16. CUE
