- Page 9 WHAT CAN THE HG-2 DO? Add Harmonics and Saturation (in multiple ways) The main signal path of the HG-2 travels from the input transformers to the Pentode amplification stage, on to the Triode amplification stage and finally to a passive output attenuation before hitting a pair of Cinemag output transformers.
- Page 10 INTRODUCTION Increase RMS of your signal The same controls that allow you to enhance your signal with harmonics, also allow you to increase the RMS of your signal by pushing the tubes into saturation and natural compression. Each tube stage is specifically setup to have a range that goes from clean reproduction of the signal to full saturation where the peaks are compressed and the average level is increased.

Page 11: Getting Started
GETTING STARTED WHAT SETTING SHOULD I START WITH? When setting up the HG-2, start with a neutral setting that closely matches the original signal. To match, use the bypass to switch back and forth as you make adjustments. Pentode: 12 o’clock NEUTRAL SETTING* Triode: 10-11 o’clock... - Page 12 GETTING STARTED Shaping tone In addition to the harmonic and saturation control, the HG-2 also allows the user to shape tone via the “tilt” selector and the “air” switch. The “Sat. Freq.” selector The 3 position “Sat. Freq. ” selector is a simple yet powerful feature that allows the user to choose what are present in the parallel saturation circuit.
