REGA IO - Amplifier Manual

SETTING UP

The io will work well on most surfaces, such as a shelf or table, provided there is sufficient air around the amplifier to prevent overheating. If using a turntable, magnetic interference can be avoided by positioning the amplifier as far away from the cartridge as the tonearm lead will allow. It is recommended not to stack other hi-fi equipment directly on top of the amplifier. Never place it on fabric or carpet.

CASE CAN GET HOT.

CONNECTIVITY

All inputs are made via RCA (phono) connectors:

• Input 1: Phono (turntables)
• Inputs 2 and 3: Line level inputs

GROUNDING

You may need to ground your turntable via the tonearm. For Rega turntables, grounding is achieved via the Phono lead ground; therefore, a separate ground is not necessary. If your tonearm has a separate ground lead, it will need to be connected to the grounding nut located on the back panel of the amplifier. You can use the nut to clamp down onto the grounding wire, but ensure that the turntable and io are as far away as possible whilst ensuring the safety of both products.

LOUDSPEAKERS

The io is capable of driving all normal hi-fi loudspeakers. Rega recommends using loudspeakers with a nominal impedance of 6-8 Ω. It is possible to run speakers as low as 4 Ω, however, such units may cause the case to exceed 40°C above the ambient temperature.
If in the event that the speaker leads are shorted, the fold back short circuit protection will protect the output stage from excessive currents. This protection circuit is not placed in the audio signal path and therefore does not affect sound quality.

ALWAYS TURN OFF THE AMPLIFIER WHEN CHANGING LEADS AND SPEAKER CABLES.

HEADPHONES

The io is capable of driving all standard hi-fi headphones. The headphone output has been characterised to match most commonly used headphones (see specifications for the output levels). When a headphone is inserted into the socket, the speakers will automatically be turned off. However, it is recommended to reduce the volume of the io before connecting any headphones to ensure they are not damaged and prevent any hearing damage.


THE io IS CAPABLE OF GENERATING HIGH SOUND PRESSURE, POSING A HEARING DAMAGE RISK. TO PREVENT POSSIBLE HEARING DAMAGE, DO NOT LISTEN TO HEADPHONES AT HIGH LEVELS FOR LONG PERIODS OF TIME.

BACK PANEL

1. PHONO STAGE INPUT 1 (TURNTABLE)
   This input is a phono stage that can be used with moving magnet (MM) or specifically high output moving coil (MC) cartridges.
2. LINE LEVEL INPUT 2 & 3
   Line inputs enable the connection of any additional sources such as CD players, Blu-ray players, streamers etc.
3. LOUDSPEAKER OUTPUT
   Top row: Left speaker - red and black
   Bottom row: Right speaker - red and black
4. MAINS INPUT
   Only for use with mains supply stated on ratings label.
5. FUSE
   Replace only with specified fuse (see specifications for the fuse rating of your product).
6. GROUNDING NUT
   For grounding third-party tonearms.

INPUT SELECTION

1. ON/OFF BUTTON
   To turn the io on, press the black power button. After a few seconds, you will hear a relay 'click' and the io will be operational.
2. HEADPHONE SOCKET
   3.5 mm stereo headphone jack.
3. INPUT DISPLAY
   To change between inputs, press the small black button located next to the row of input digits to cycle through 1-3. The selected input is highlighted by the number lighting up in red. Input selection can also be changed with the remote.
4. VOLUME CONTROL
   The volume control has a minimum and maximum value which is indicated by the notch. The volume does not reset after each use. Before plugging in headphones, make sure the volume is reduced.
5. MUTE
   Mute on the io is controlled by the remote (see next page).
