ifi MZ99 Headphone Amp Instruction Manual

ifi MZ99 Headphone Amp

Thank you for purchasing the CAN Signature from ZEN series. The CAN Signature MZ99 is a balanced headphone amplifier optimized for Meze headphones.

PRODUCT SPECIFICATION

1. Power switch

2. Input channel switch

   • Input 1: RCA
   • Input 2: Single-ended 3.5mm
   • Input 3: Balanced 4.4mm

3. Power Match selection: OdB/6dB/1 2dB/18dB
   We recommend starting from OdB and then increasing the switchable 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/iFiaudio is not responsible for any damage/injury from misuse.

4. Analogue Volume Control
   At normal istening 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 output
   For 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 output
   For connecting balanced 4.4mm headphones.
   Tip: As the Meze headphones use balanced design, we recommend the 4.4mm balanced output.

7. MZ99 LED
   Headphone corrections optimized for Meze headphones.

8. XSpace Matrix LED

   • The XSpace Matrix(on/off) recreates a holographic sound field.
   • It is a pure analogue signal processing circuit designed for listening to headphones as ifone 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 Meze headphones nor XSpace 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. Settings
   This button chooses between:

   • Off
   • MZ99
   • XSpace

10. Balanced 4.4mm analogue input
    This is a balanced analogue in put.

11. Single-ended 3.5mm analogue input
    For connecting single-ended 3.Smm input.

12. RCA analogue input
    This is an analogue input.

13. Balanced 4.4mm analogue output
    This is an analogue output via 4.4mm> XLR or other balanced interconnects. You could use this for an active speaker.
    Tip: As the ZEN CAN Signature MZ99 is balanced, this is the recommended output.

14. DC 5V power
    Please connect the ZEN CAN Signature MZ99 to the enclosed power supply, the super-silent iPower2. The ZEN CAN Signature MZ99 must ONLY be powered by 5 volts.
