7. Do not operate the amplifier near heat producing devices such as radiators, heat registers, stoves or other apparatus that produce heat. 8. Always operate the unit with the chassis ground wire connected to the electrical safety earth. Do not defeat the safety purpose of a grounding-type plug. A g...

4. Vhf protect indicator this indicator illuminates if signals above 12 khz are continuously present at full power at the output terminals. If this occurs the input signal is muted, and the process cycles until the vhf signal is no longer present. (see page 16 ) 5. Clip/limit indicator this indicato...

7. Link/bridge switch two of the switches in the dip switch are used for link and bridge operation. (see page 6 ) 8. Gain switch channel a three of the switches in the dip switch selects the maximum gain of the channel to be either 20, 23, 26, 29, 32, 35, 38 or 41db. (see page 6 ) 9. Ac power cable ...

Rknkp= léíáçåë= as the dip switch is recessed, one may put a sticker across the bay to prevent from unauthorized changes. Another option is to completely remove the dip switch. This should be done by authorized service personnel only! It corresponds to all switches set to “off”, i.E. 32db gain and s...

Rkpkq= _êáÇÖÉ=ãçåç=ãçÇÉ= the bridge mono mode is used to deliver both channels' power to a single load. The nominal impedance of the load must be more than 3 ohms. Set the link switches to the “on” position and use one of the input connectors. You may use the remaining input connectors to carry the ...

Mls tm settings can be different for each channel, and a variety of combinations can be achieved – see table 2. Table 2 provides the simplest way to find the best mls tm settings for your application. There is no risk to damage the amplifier since it is very well protected (even down to 0.3 ohms). T...

Long-term current draw. Read more about the afs limiter under “protection” on page 16 . There is also a technical note on our website www.Labgruppen.Com : afs limiting and power consumption. It is more useful to state the current draw in different loads and output power levels. These figures can be ...
