4.3 Ho Hokela Libui

Connect your speakers to the appropriate output terminals on the rear panel (COM, 4Ω, 25V, or 70V). Ensure that the speaker impedance and voltage rating match the amplifier's output to prevent damage. For 25V/70V systems, ensure proper transformer taps are used on the speakers.

4.4 Hokela Mehloli ea Molumo

• Keletso 1: For balanced line-level or microphone sources. Use the terminal block and set the Line/Mic/Phantom Power switch accordingly. If using a condenser microphone, enable phantom power.
• Input 2 (RCA): For unbalanced line-level audio sources. Connect your device (e.g., CD player, media player) using RCA cables.

4.5 Khokelo ea Matla

Connect the supplied AC power cord to the AC Power Inlet on the rear panel and then to a suitable wall outlet. Ensure the power switch on the front panel is in the OFF position before connecting to power.

Gradually increase the Input 1 or Input 2 level control for the active audio source until the desired volume is achieved. Monitor the Signal and Peak indicators:

• The Letshwao indicator should light up when audio is present.
• The Tlhōrō indicator should only flash occasionally during the loudest parts of the audio. If it stays lit constantly, reduce the input level to prevent distortion and potential speaker damage.

5.3 Taolo ea Molumo

Use the Bass and Treble controls to adjust the tonal characteristics of the audio output. Turn clockwise to boost frequencies and counter-clockwise to cut them. Start with the controls at the '0' (center) position for a flat response.
