AC Power connection 240V / 230V / 220V / 115V / 100V AC dependent on country.
Digital output Phono/RCA
Unbalanced vacuum tube outputs Phono/RCA right/left
Balanced signal outputs XLR right/left

We recommend to connect signal cables to the CD-player when the CD-player and all the
other units of the audio system is switched off.

The CD-player has two types of analog audio outputs: unbalanced (vacuum tube) audio
signal with RCA plugs (phono plugs) and true balanced audio signal with XLR plugs (pin 2 is
positive phase, pin 3 is negative phase and pin 1 is chassis earth).

The CD-player has got one RCA standard SPDIF digital audio output. Digital signal level is

0.5Vpp when terminated in 75 ohm load. This is the standard load impedance of external
DAC's and other recording equipment.

CONSONANCE REMOTE CONTROL

The Consonance Reference CD-2.2MK II can be controlled by remote control. Like other Hi­End products, the number of buttons on the remote is kept to a minimum. The remote
control uses two 1.5-volt LR03 AAA batteries.

USE & PLACEMENT

The Consonance Reference CD-2.2MK II should be placed on a flat, hard surface for proper
isolation against vibrations. The CD-player performs best after being switched on for about
30 minutes for heating upage A certain space is required for air circulation above and below
the CD-player. The CD-player must never be placed on a carpet or similar surface that
obstructs air circulation through the component. Nor must it be covered while in use or
placed on a narrow shelf or in another confined space.

CLEANING

The top cover are made of cherry wood, while the front panel, side panels are made of
brushed / blasted and anodized aluminum. Fingerprints or stains on the front panel, knobs
or top cover can be removed with a cloth moistened with warm water.

We wish you good luck in setting up and connecting your new CD-player and hope that it
will give you many years of joyful natural sounding music experiences!
