Page 3: Important Remark
1. IMPORTANT REMARK The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the appliance. - Page 4 8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. 9. Do not defeat the safety purpose of the polarized or grounding type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong.

Page 7: High-Pass Filter
Each input connector (INPUT CH1, INPUT CH2, etc., depending on the model) has an adjacent STACK link connector (same signal available in INPUT), enabled to connect the same input signal to several inputs or devices. 5.4 High-pass filter Each input channel has a switch which activates (ON) or deactivates (OFF) its high pass filter: 3 order Butterworth with cut-off frequency at 75 Hz. -
Page 8: Indicators
6.3 Indicators eHSA amplifiers include a simple yet effective indication system. PROT indicators show the absence of loudspeaker output signal. These indicators may light up for following reasons: During start-up, until the boot time time has passed. This time period is needed for the internal operating voltages to settle. -
