User manual PEAVEY AUTOMIX

[. . . ] Intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. CAUTION: To reduce the risk of electric shock, do not remove cover. WARNING: To prevent electrical shock or fire hazard, do not expose this appliance to rain or moisture. Before using this appliance, read the operating guide for further warnings. [. . . ] If you have to deal with both loud and quiet events, you will need to trade off between natural sounding ambient and background noise. mASTER GAIN TRIM (14) The Master Gain Trim sets the maximum overall system gain. This control should be set with the front panel master gain at maximum (all channels at unity) and external power amps turned up and locked at operational settings. When trimmed to a safe margin below feedback, no combination of user controls can cause feedback. BACK PANEL FEATURES MIC INPUTS (15) For use with low impedance microphones or low level sources. This is a transformer balanced input with an impedance of 2, 000 ohms. LINE INPUTS (Channels 3-8) (16) These allow line level inputs to be used in channels 3-8. This is a transformer balanced input through a 30 dB resistive pad. DIRECT OUTPUTS (17) Each channel has a set of direct output terminals that can be used for recording or anytime the output of an individual channel is required. The level of this signal is independent of "Automix" gain manipulations. MUTE (18) Channels can be muted individually by shorting this terminal to ground. STATUS OUTPUT (19) The status is a DC logic output that is low (0 volts) when the channel is active and high (3. 8 volts) when the channel is not active. This DC voltage can be used to key video cameras or trigger key lights on active microphones. LOOP (Channels 1 and 2) (20) This is a signal loop that allows an external device such as an EQ to be inserted into the signal path of the first two channels. When used without external processing these loops are hardwired. MUTEBUS (21) The Mutebus is a control port that when shorted to ground will mute all channels that are assigned to the mutebus (approximately 45 dB). The channels to be muted must be attached to the mutebus using the internal switch marked OFF/MBUS. REMOTE VOLUME (22) The master level of the mixer can be controlled remotely with a simple connection on the back of the unit. If desired, a control voltage can be inserted to command 0 to 70 dB of attenuation. LINK PORT (23) To increase the number of inputs available, multiple Peavey Automix's can be linked together. linking automixers is a very simple process. [. . . ] Pour obtenir la plus large plage d'atténuation possible par commande à distance, il est nécessaire que la mollette de gain du panneau interne soit tournée à fond dans le sens des aiguilles d'une montre. Réglage initial des commandes : Niveau des canaux (panneau avant) Mollettes de réglage de gain (panneau interne) Priorité (panneau interne) Réglages des filtres coupe-bande (panneau interne) Sur-atténuateur des niveaux bas (panneau interne) Niveau master (panneau avant) Niveau master (panneau interne) Tous les canaux en mode automatique Peavey Electronics Corporation warrants to the original purchaser of this new Architectural Acoustics product that it is free from defects in material and workmanship. " Power supply cords should always be handled carefully. Never walk or place equipment on power supply cords. [. . . ]
