ZEN CAN Desktop Headphone Amplifier User Manual

ZEN CAN Desktop Headphone Amplifier

Thank you for purchasing the CAN from ZEN series. The CAN is a balanced audio amplifier.

1. Power switchPress and hold button for two seconds to turn on.

2. Input channel switchUse the button to choose between the following input options: Input 1: RCA Input 2: Single-ended 3.5mm Input 3: Balanced 4.4mm

3. Gain selection: 0dB/6dB/12dB/18dBAlways start from 0dB and then increase the gain level to attain an enjoyable and comfortable level of volume from the headphones.Warning: at the outset do not use excessive gain, otherwise damage to hearing or connected headphones may ensue. AMR/iFi audio is not responsible for any damage/injury from misuse.

4. Analogue Volume ControlAt normal listening levels, the volume control should be around the 12 o’clock position. Increase the gain level to enjoy a higher listening level.

5. Single-ended 6.3mm outputFor connecting single-ended 6.3mm headphones. With single-ended 3.5mm headphones, connect with a 3.5mm to 6.3mm adapter.

6. Balanced 4.4mm analogue outputFor connecting balanced 4.4mm headphones.Tip: As ZEN CAN is balanced, we recommend the 4.4mm output.

7. XBass® LEDXBass® (On/Off ) was uniquely designed to extend bass response to suit different headphones. It is a pure analogue signal circuit.

8. 3D® Matrix LEDThe 3D® Matrix (on/off ) recreates a holographic sound field. It is a pure analogue signal processing circuit designed for listening to headphones as if one was listening to speakers. This addresses the ‘music inside the head’ sensation, which makes for unsettling listening.Tip: Sonically-hindering DSP is NOT used for XBass® nor 3D® Matrix systems. They use the highest-quality discrete components and operate purely in the analogue domain. Hence all the clarity and resolution of the original music is retained.

9. SettingsThis button chooses between:– Off– 3D®– XBass®

10. Balanced 4.4mm analogue inputThis is a balanced analogue input.

11. Single-ended 3.5mm inputFor connecting single-ended 3.5mm input.

12. RCA analogue inputThis is an analogue input.

13. Balanced 4.4mm analogue outputThis is an analogue output via 4.4mm > XLR or other balanced interconnects. You could use this for an active speaker.Tip: As ZEN CAN is balanced, this is the recommended output.

14. DC 5V powerPlease connect ZEN CAN to the enclosed power supply, ZEN CAN must ONLY be powered by 5 volts.

Tip: For best performance upgrade the enclosed power supply to a super-low noise power adapter such as iFi iPower or iPower X.
