Page 5: Important Notes Concerning Emc
To ensure continued compliance with the EMC directive the following precautions should be observed : • For connections to the line-inputs of the ARGOS, use standard coaxial cinch cables. • When it's necessary to extend the microphone cable, use standard coaxial microphone cable. -
Page 6: Important Safety Notes
Important safety notes. The Apex ARGOS was designed and manufactured to meet strict quality and safety standards. There are, however, some installation and operation precautions which you should be particularly aware of : READ AND RETAIN INSTRUCTIONS - All the safety and operating instructions should be read before the appliance is operated and retained for future reference. - Page 7 The cord must consist of a minimum 18 AWG and a grounding type attachment plug, rated 15A, 250V. • In case the ARGOS contains a mains supply for use in the UK : 100V/120V, use an UL listed cord set consisting of a minimum 18 AWG, type SVT or SJT three conductor cord, a maxi- mum of 15 feet in length and a parallel blade, grounding type attachment plug, rated 15A, 125V.

Page 8: Installation And Precautions
INSTALLATION • The ARGOS may be rack-mounted or free-standing. • The ARGOS will accept voltages from 220 to 240 Vac, 50 / 60 Hz. No voltage regulation setting is necessary. • As with all pieces of precision electronic equipment, follow the next rules when using the ARGOS : - Do not subject the equipment to shocks or vibration. -

Page 11: Introduction
This is the reason why most amplifiers have a loudness-switch to compensate for this effect. In the ARGOS, this sensitivity-difference of the human ear is taken into account in the measurement of the sound pressure level. An “A”-weighted filter in the measuring chain passes the mid-frequencies and attenuates the low and high frequencies. - Page 12 If one uses an active system (separate amplifiers for different frequency ranges), the output of the ARGOS should be connected to the input of the electronic cross-over. See the figures below on how to connect the ARGOS in the audio chain for the 3 different opera- tion modes :...

Page 13: Operation Modes
This Line operation mode is particularly suited in those cases where the maximum allowed SPL is low (<80dBA). If the ARGOS is used to protect an installation from damage or if it is used as a sound leveler, this is also the best solution. -
Page 14: Hold Mode
HOLD mode Hold Mode By means of the "MODE" pushbutton (7), ARGOS can be put in hold mode. The purpose of the hold-mode is to prevent a decrease in gain reduction when no signal is available at the input com- ing from the source (mixing desk). -

( 18 ) Loudspeaker input : When the mode selection switch is set to LS, the ARGOS will base its limiting operation on the level measured on both loudspeaker-inputs. So if LS-operation is desired, the LS-outputs of the power amplifier should be con- nected to these inputs. -
Page 19: Installation Instructions
• Connect the LINE- or MASTER-output of the pre-amplifier or the mixing desk to the LINE- input of the ARGOS. • Connect the LINE-output of the ARGOS to the input of the power amplifier or if an active amplification system is used, to the input of the electronic crossover. - Page 20 • When more then 1 amplifier is used and if the maximum admissible sound level is < 80dBA • In these cases where the use of a microphone is not desired. • When the ARGOS is used in mobile installations to protect the speakers from overload. • When the ARGOS is used as a sound leveler.

ARGOS. Dirt on components acts as an insulating blanket, preventing efficient heat dissipation. It also provides an electrical conduction path that could result in failure, especially under high-humidity conditions. Normally, internal cleaning of the ARGOS is not necessary when the cover is left in place. ARGOS - USER MANUAL... -
