The PMBL is a 2 channel passive line level merge box. Each channel has 2 balanced XLR/f inputs. The input signal is merged via a resistor network to a XLR/m output.The top side input is transformer isolated. Possible applications might be the routing of two mixing desks to one power amp or mixing a stereo signal down to mono.

Studio level line isolating and split transformer. Inputs and outputs work with balanced and unbalanced lines. Electrostatic shieldig, mu-metal shielding on request. PCB mount, PCB for 2 x PMT-06 available (#PCB-06). Technical specifications: Ratio 1 : 1 + 1 Nominal impedance input and outputs: 600 ohms Frequency range: 30 Hz - 20 kHz, +/- 0,5 dB Level: + 20 dB max. Dimensions: (without pins):

All inputs and outputs are balanced transformer isolated
Extremely reliable: Should one output be shorted, the other outputs remain unaffected
Line input and outputs
Adjustable input gain (-8 to +25dB)
Level meter
Headphone output to monitor the input level, headphone volume adjustable
Individual ground lift switches for each output
Ground Lift switch for the input
Expandable setup thanks

A stereo version of the PPB20 is also available. Instead of having one microphone and one line input the stereo version has two line inputs.

The first input is split on to the upper row of outputs i.e. on to the odd channels whereas the second line input is split on to the lower row of outputs, i.e. the even channels.
