Identification: 1. POWER SWITCH 2. POWER - Power indicator 3. BASS - Adjust bass response. Rotate clockwise to increase bass output and anticlockwise to reduce it. 4. TREBLE - Adjust treble response. Rotate clockwise to increase treble output and anticlockwise to reduce it. 5. - Page 6 Inputs Short cables runs improve the sound quality remarkably. Input cables should be short and direct, since high frequencies will mostly be absorbed if the cables are unnecessarily long. Besides that a longer cable may lead to humming and noise problems. If the cable runs are unavoidable, you should use balanced cables.
