POTENTIOMETERS
All potentiometers in the Pubmate are manufactured by ALPS and completely sealed, making them very
insensitive for smoke and humidity which is a distinct advantage in locations with a lot of smoking.
INPUT CONNECTORS
Every stereo line input has two Cinch connectors. The stereo line inputs need to be connected as follows.
The left Cinch connector is the left input and the right Cinch connector is the right input.
The shield needs to be connected to the ground. The level needs to be between -10dBu and +10dBu.
The Mic inputs can be connected on the front or on the backpanel via 3 pole female XLR connectors
SPECIAL OPTIONS IN YOUR PUBMATE
Channel 7 and 8 are equipped with a special phono correction amp that needs to be activated when phono
players are connected to these channels.
Before you do this make sure you turn off the Pubmate and remove the mains cable from the mixer.
Just alongside fader 7 and 8 is a small hole labelled “phono” This is the position where the switch is mounted
on the backside of the input PCB. These are the switches that need to be pushed down to activate the RIAA
correction amp. Use a small screwdriver to remove the cover and slowly push down the switch once. If you
need this channel for line level purposes again, just de-activate this switch by bringing it in its up position.
If this is all too difficult for you or you simply do not want to do this, ask your dealer for help.
MASTER SECTION
The Pubmate’s master section is located on the right side of the mixer and houses all the electronics to sum
all the input signals and PFL signals. Also the power supply and the headphone amp are located here.
PEAK LED
The master section has a big two colour LED reading all in and outgoing signals. The attack and release
timeconstants are designed to easily hold peaks a little while longer for easy indentification.
The output of your Pubmate is +4dBu (1.23v) when the LED is green with occasional being red on peaks.
EQUALISATION
The output section has a stereo 3 band equalizer for tonal corrections.
The “High” control can increase or decrease the amount of high frequency content of your signal.
The “MID” control has a special amplifying range with a bell curve, amplifying or attenuating only frequencies
in the mid region of the frequency spectrum.
The “LOW” control also has a special curve called bell. This is a special design that avoids damage to your
loudspeakers when volume is pumped up too high. Below 40 Hz the low frequency contents start to decrease
again even with your LOW control fully turned up. The result is a tight bass without distortion due to overload
of the loudspeakers.
MASTER OUTPUTS
The Pubmate master volume controls A and B seperately control the two stereo outputs of the console
Both outputs have separate XLR connectors and Cinch connectors for easy interfacing with amplifiers.
PHONES
The phones output (located on the frontpanel) has an automatic input selector.
Normally the left/right output is heard until a PFL switch is activated anywhere in the console that inmediately
takes over the left/right signal. We advice you to use headphones with an input impedance not lower than 16
Ohm to avoid distortion. An 8 Ohm headphone will produce lots of distortion when cranking up the level due
to its low impedance load. It is a load equivalent to the load that loudspeakers normally present to power
amps and as you know the Pubmate is no power-amp, sorry.
