6.BALANCED SIGNAL INPUT JACK (1/4" TRS)

This 1/4" TRS (Tip/Ring/Sleeve) phone jack is wired for balanced input signals (0.775V=0dBm, 15K Ohms) and signal polarity is Tip = Cold (+), Ring = Hot (-), and Sleeve = Ground.

7.BALANCED SIGNAL OUTPUT JACK (1/4" TRS)

This 1/4" TRS jack provides a balanced signal output (600 Ohms) and is wired with the same signal polarity as the Input Jack above.

8.24 VDC TERMINAL

Use this screw terminal to operate the unit with external 24 VDC powering, either from a power supply or a battery. Observe the correct polarity (+ and -) when making connections as marked on the terminal. The power requirement is 250 mA.

9.AC FUSE HOLDERS

This fuse holder contains an AC primary fuse. When this fuse blows, replace it with the same type fuse, size and power rating (120 VAC: 0.315A/250V; 230 VAC: 0.2A/250V). If it continuously blows, stop replacing the fuse and refer servicing to qualified personnel.

CAUTION: After checking the AC supply voltage, be sure that the correct fuse is in the fuse holder.

10.POWER CONNECTOR

The IEC cord connector is used to connect the AC power source to your power amplifier.

CAUTION: DO NOT REMOVE THE CENTER GROUNDING PIN.

11.AC VOLTAGE SELECTOR SWITCH

Before plugging in the power cord, check to see that the unit is set for the proper voltage for your area: ~115V (60Hz) or ~230V (50Hz).
