Connecting Power
Read and understand the Important Safety Instructions printed at the
start of this guide, and the warnings printed on the rear of the console. Check
that your local mains supply is within the 100-240V operating voltage range
allowed. Check that the correct mains lead with moulded plug has been sup-
plied with your console. Make sure that the IEC mains plug is pressed fully
into the panel socket before switching on.
Grounding
The connection to ground in an audio system is important for two reasons:
1. SAFETY - To protect the operator from high voltage electric shock, and
2. AUDIO PERFORMANCE - To minimise the effect of ground (earth) loops which result in
audible hum and buzz, and to shield the audio signals from interference.
3. For safety it is important that all equipment grounds are connected to mains ground so that
exposed metal parts are prevented from carrying high voltage which can injure or even kill the
operator. Do not disconnect the ground connection in the mains lead. It is recommended that
the system engineer check the continuity of the safety ground from all points in the system
including microphone bodies, turntable chassis, equipment cases, rack metalwork and so on.
Switching the console on and off
It is good practice to turn power amplifiers off before switching the console and any other con-
nected equipment on or off. This prevents any unexpected clicks or thumps when the equip-
ment is powered up.
Turn amplifiers and powered speakers on last and off first.
To turn the console on, press the ON/OFF switch next to the IEC mains input socket. To turn
the console off, press this switch again.
