the 5 Amps RMS current limit. It is not recommended to use loads below
2 n as power dissipation on the heat sink will rise considerably.
When the 1.8 Amps RMS current limit is selected, it does not affect the
voltage limit which remains 15 Volts RMS. Maximum power will therefore
be available with a load of about 8 n. The 1.8 Amps RMS limit can be used
to drive the Mini-Shaker Type 4810 safely at full rating. Fig.4.3 shows the
maximum power
available as a function of load resistance for the two
current limits.

A typical frequency response curve is shown in Fig.4.4. The specified
frequency
range of Type 2706 is 10 Hz to 20 kHz (± 0.5 dB).
