Audio processing for base operation is possible with the use of rack audio processing gear or computer
based processing such as ProTools for PC or Mac along with the companion interface such as the Mbox 2
Mini or newer. The Asymod IIIs is NOT designed to give transceivers more RF power, more swing, or loud
distorted modulation, as many, which are not accustomed to, or appreciate the high fidelity audio
desire.
The Asymod IIIs may be set up in one of the three following configurations:

A- Single MJE3055T transistor (Q2) with a maximum collector current of 10 Amps.

B- Dual MJE3055T transistor (Q2 & Q3) with a maximum collector current of 20 Amps. (Request)

C- Single TIP35C transistor (Q4) with a maximum collector current of 25 Amps. (Request)
Although configuration A will work fine with most 4 watt transceivers, for heavy use, configurations B or
C is recommended which withstand higher duty cycles at lower temperatures and are available upon
request.
NOT FOLLOWING THE INSTRUCTIONS ON THIS MANUAL MAY LEAD TO PERMANENT DAMAGE TO THE
ASYMOD IIIs UNIT!
Make sure to follow the wiring instructions in this manual every time the unit is installed.
Terminal, Component, and Adjustment Locations
IMPORTANT: The modulator’s output transistors, Q2, Q2+Q3 or Q4, whichever combination
used, must be mounted on a reasonable size heatsink to maintain operating temperature to a
minimum. Ventilation is recommended.
