We will recommend using the balanced XLR outputs from the CD-player, as these will have the
absolute highest level of sound quality.
The CD-player has got one balanced transformer coupled 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.
AUDIO OUTPUT LOW PASS FILTER
The audio low pass filter in the Hegel CDP4A is factory set for a slow roll of to preserve a highest
possible accuracy of timing information without excessive ringing in the time domain. In normal use
Hegel recommend to use the output filter in the slow roll off factory setting mode. However if the user
has a special requirement there is a possibility to change the setting of the low pass filter to a fast roll
off mode by moving a jumper on the DAC-board inside the player. For information about changing the
HEGEL REMOTE CONTROL RC2
The Hegel CDP4A can be controlled by the included Hegel RC2 system remote control. Like other
Hegel products, the number of buttons on the remote is kept to a minimum.
The Hegel system remote control will also control other Hegel products like amplifiers and
preamplifiers, avoiding the need of several different remote control devices.
The remote control uses two standard 1.5-volt LR03 AAA batteries. To insert the batteries please use a
normal type cross head screwdriver to gently remove the four screws in the bottom of the remote
control. Be careful and use a normal cross head screwdriver to remove the four Philips cross head
screws. Do not use a Pozidrive cross head screwdriver, it can damage the head of the screws.
Be sure to insert the batteries with the correct polarity with + sign and – sign as shown inside the
battery holder, and be careful when inserting the batteries to not damage the battery holder.
Be careful when inserting the screws after fitting the batteries. Please turn the screws gently by hand
first to avoid damaging the threads in the remote control body. The threads are made in a soft metal
and can be damaged if screws are inserted by force. Do not tighten the screws to hard, as this also can
damage the screws and the soft metal body of the remote control.
Please do not drop the remote control hard down in the floor, as this can damage internal parts of the
remote control and the battery holder.
To avoid damage to the remote control by leakage from the batteries during transport and storage, the
remote control is supplied without batteries from Hegel.
