2. CONTROL ELEMENTS
3 The 4-digit INPUT LEVEL display shows the input level over a range from -24 to +12 dBu. The ON LED
lights up when you switch on the HA4600.
4 The HEADPHONE OUT socket is connected in parallel with the output sockets on the rear panel and
provides an additional means of listening to the individual channels. This function is particularly useful
when the equipment has been permanently installed in a rack.
5 A further input signal can be mixed in to the MAIN or the DIRECT IN-Signal via the AUX IN-input.
6 The L MUTE switch mutes the left input signal.
7 The R MUTE switch mutes the right input signal.
8 The MONO switch can be used to switch each of the amplifiers from stereo to mono operation.
9 The BASS control can be used to increase or decrease the lower frequencies (+/-15 dB).
10 The TREBLE control can be used to increase or decrease the higher frequencies (+/-15 dB).
11 The BALANCE control sets the ratio level between the MAIN or DIRECT IN signal and the input signal,
which was applied to the AUX input.
12 The OUTPUT LEVEL control is used to set the sound level of each individual amplifier. At the same time
it also controls the left and right channels.
13 The 8-digit OUTPUT LEVEL display monitors the output level of each individual channel over the range
from -24 to +12 dBu. If the Clip-LED lights up, please reduce the gain of the current channel, otherwise
distortion may result.
