I N S TA L L AT I O N To ensure years of enjoyment from your NADY AUDIO PRM-400 powered mixer console, please read this manual thoroughly before using the unit. 1. INSPECTION Your NADY AUDIO PRM-400 was carefully packed at the factory in packaging designed to protect the units in shipment. Before installing and using your unit, carefully examine the packaging and all contents for any signs of physical damage that may have occurred in transit.
CONTROLS AND CONNECTIONS 1. CHANNEL INPUT SECTION which are usually added to the dry signal, dynamic processing is normally applied across an entire signal. Here an Aux Send would be inappropriate. Instead, the signal is intercepted somewhere along the channel, fed through the dynamics processor and/or EQ, then returned to the console at the same point where it left. The insert point is normalized, i.e., the signal is only interrupted when a plug is plugged into it.
CONTROLS AND CONNECTIONS (7) (5) PAD This control attenuates the input signal -20dB when set to the IN (button depressed) position. The key to successful equalization is to avoid excess. Too much equalization on the input channels will result in a mix that is smeared together with nothing specifically defined. During rehearsals, experiment with the equalizer controls on various instruments, vocals and combinations of these mixed together to become familiar with various equalizer settings.
CONTROLS AND CONNECTIONS 2. MASTER SECTION (13) (16) (17) (12) (14) (18) (15) (22) 7 BAND MASTER MIX GRAPHIC EQUALIZER (25) EQ BYPASS SWITCH (26) AUX/MON SELECT SWITCH (14) STEREO MASTER INSERTS-PRE EQ (15) STEREO MASTER INSERTS-POST EQ The final Master Mix is output directly to the Main Speaker outputs (42). These L/R outputs provide 200W at 4 ohms for powering P.A. speakers rated for this power or more. Channel A and B parallel outputs allow multiple speaker setups.
CONTROLS AND CONNECTIONS The PRM-400 is equipped with a 7band Stereo Graphic Equalizer (22), allowing final tonal adjustments on the Master Mix. This master EQ is post-Stereo Master faders (27A,27B) so you must exercise care in the proper use of these EQs for best overall sound [see also INPUT SECTION, (6) EQ above]. The EQ Bypass switch (25) can be used to add or eliminate the Stereo EQ from the Master Mix (button depressed=EQ bypassed).
CONTROLS AND CONNECTIONS by the Channel faders, and the Right speaker output is the signal controlled by the Channel AUX controls (7). Therefore the Main speakers, for example, can be controlled by the individual Channel faders (11) and the Left Master fader (27A), and the Monitor speakers by the Channel AUX controls (7) and the Right Master fader (27B). In this mode, any Master EQ (22) or Effects (8,28,32) selected on the EFECTS bus will be output on both the Left and Right Speaker outputs.
CONTROLS AND CONNECTIONS (38) (40) (39) (42) (41) BACK PANEL The PRM-400 is fused for your (and its own) protection. If a fuse blows, disconnect the AC cord, and replace the fuse with a 6.0A (5x20mm, 250V) type, available at electronics stores or through your dealer. If the fuse blows continuously upon replacement, unplug the unit and refer to qualified personnel for servicing before further use. and is pre the master AUX send control (30).
