Página 17: Introduction
Introduction SC Amp is the world's only dedicated audio test amplifier. Specifically designed for the audio test market, it incorporates several patented features unique to the needs of audio test and measurement. Unnecessary features found in regular audio amplifiers have been eliminated to keep production line operation simple and error-proof. -

Página 19: Operation
AC power from the power brick for several minutes and then try again. Short Circuit Monitoring The output of SC Amp is protected in case of a short across the amplifier output. It's fast, automatic, and does not trigger the thermal monitor since the internal temperature does not necessarily rise very much during a short circuit condition. -
Página 20: Single Speaker Test Example
8 Ohms in parallel with 8 Ohms equals 4 Ohms. SC_Amp’s performance will vary with loads below 4 Ohms. Impedance Measurement When using SC Amp with SoundCheck, the Impedance Analysis Step should use the AmpConnect/SC Amp circuit model as shown in Figure 7-3. -
Página 21: Bnc Connections
Tip and Ring of a 1/4” TRS male phone plug wired to the Center conductor and Shield of a BNC connector. The TRS Plug connects to the Impedance Interface Output of SC Amp. Since the BNC input is single ended, this connection allows you to connect to the differential output of the Impedance Interface Output which is essential for the correct operation of this circuit. -
Página 22: Use With Dc Connect
Use with DC Connect Voice Coil Offset (DC Offset) SC Amp can be used with external voltage sources in order to apply an offset to the stimulus sent to a speaker under test. The example in Figure 7-6 shows SoundCheck controlling Listen’s DC Connect in order to supply a DC Offset voltage to SC Amp. - Página 23 DC Offset vs Output Voltage Limit As DC Offset is applied, the maximum output voltage (Vp-p) of SC Amp decreases. Positive Voltage Limit Vp-p - Max output voltage before clipping Negative Voltage Limit Figure 7-7: Maximum Voltage Limit Figure 7-7 shows the signal at the full output voltage (Vp-p) of SC Amp.
