User manual PEAVEY AAM 250 DATASHEET

[. . . ] Refer servicing to qualified service personnel. WARNING: To prevent electrical shock or fire hazard, this apparatus should not be exposed to rain or moisture, and objects filled with liquids, such as vases, should not be placed on this apparatus. Before using this apparatus, read the operating guide for further warnings. Este símbolo tiene el propósito, de alertar al usuario de la presencia de "(voltaje) peligroso" sin aislamiento dentro de la caja del producto y que puede tener una magnitud suficiente como para constituir riesgo de descarga eléctrica. [. . . ] The mic gain can be set by pressing the PFL button (12) and adjusting for ø dB on the output meter. If the clip LED comes on and remains lit, reduce the gain. Stereo Gain This control establishes the nominal operating level for the stereo line inputs (1/4" jacks) of the channel. The Stereo Gain can be adjusted over a sufficient range (- to +20 dB) to accommodate almost any input level. It operates in conjunction with the L/R­CH Switch (16) to route the stereo signal directly to the L/R buses or through the channel strip. Stereo Input Channels ONLY 2 14 17 16 15 15 3 18 16 L/R­CH Switch This switch establishes the routing of the stereo line input (1/4" jacks) signal. When the switch is out, the stereo line input signal is routed directly to the L/R buses, bypassing the channel strip. In this mode, the mic input (XLR) signal is routed through the channel. When the switch is in, the stereo line input signal is routed through the channel and the mic input signal is disconnected. The signal level is controlled via the Stereo Gain control (15). Input Select Stereo-USB Switch This switch selects the input signal that will feed the stereo line input of the second stereo channel. When the switch is out, the signal from the stereo line inputs is routed to the Stereo Gain control (15). When the AFL button is out, the yellow group LED will blink as an indication of signal presence (-30 dBu). Group Fader This control varies the signal level from - to +10 dB and sends the signal from the Group to the Left and/or Right buses and to the Group Output jacks (53). The optimum setting is the ø (unity gain) position. TO AUX 1 & TO AUX 2 Controls These controls determine the level of the respective Effects Return signal that is sent to the respective AUX bus, allowing musicians/singers to hear internal and/or external effects in their monitors. NOTE: Due to the creation of an electronic feedback loop, do not use AUX Sends 1 or 2 as the path to external equipment that is to be sent back to the corresponding AUX mix (1 or 2). BAL This control determines the placement of the Effects Return signal's position with respect to the assigned L/R and Group 1-4 buses. Rotating the control counterclockwise (L) sends more signal to the LEFT output and odd-numbered GROUPS; rotating clockwise (R) sends more signal to the RIGHT output and even-numbered GROUPS. The C position sends equal amounts to each. EFX LEVEL Control This control determines the level of the Effects Return signal being sent to its assigned buses. It functions similarly to the Channel Faders (13). 1/2, 3/4, L/R Bus Assign Switches Like the channel assign switches, these buttons determine the bus assignment of the Effects Return signal. [. . . ] (3) The wire that is colored brown must be connected to the terminal that is marked with the letter L or colored red. 64 Line Fuse (16FXTM mixer only) The fuse is located within the cap of the fuse holder. If the fuse fails, THE FUSE MUST BE REPLACED WITH THE SAME TYPE AND VALUE IN ORDER TO AVOID DAMAGE TO THE EQUIPMENT AND TO PREVENT VOIDING THE WARRANTY. If the mixer repeatedly blows the fuse, it should be taken to a qualified service center for repair. WARNING: The fuse should only be replaced when the power cord has been disconnected from its power source! 19 A B C D LEFT RIGHT GROUP1 GROUP2 GROUP3 GROUP4 AUX1 AUX2 AUX3 AUX4 AUX5/EFX1 AUX6/EFX2 PFL/AFL PFLCTRL GROUPS 1-4 GROUP INSERT GROUP FADER MUTE GROUP OUT AFL SIG/ PFL MUTE/ CLIP MONO CHANNELS L/R EQ ASSIGN +48V PHANTOM PWR FROM SWITCH IN MASTER SECTION FADER MUTE LO MID HI PAN GROUP MIC 3/4 AUX1 LOW +/AUX 1-4 PRE EQ SELECT LOW CUT 1/2 GAIN HI PASS LINE MID +/- F AUX2 RIGHT AUX3 LEFT HI +/- INSERT AUX 1-4 POST EQ SELECT T=OUT R=IN MEDIA INPUT SIG/ PFL MEDIA IN LEVEL AUX5/EFX1 LEFT/ RIGHT/ MONO MONO L/R AUX4 LEFT RIGHT MUTE/ CLIP AUX6/EFX2 PFL STEREO CHANNELS PFL/AFL L/R MEDIA MUTE BALANCE +48V PHANTOM PWR FROM SWITCH IN MASTER SECTION PFL/AFL LOGIC FADER ASSIGN L/R HI +/1/2 LOW CUT EQ MIC HEADPHONE OUT HEADPHONE LEVEL MIC GAIN LO MID HI HI PASS STEREO EQ STEREO USB LOW +/- MID +/- LOGIC PFL/AFL ACTIVE SHORT TO MIX L/R & MEDIA IN REC OUT LEFT REC OUT LEVEL LEFT/ MONO 3/4 LO MID HI CHAN 15/16 ONLY AUX1 AUX 1-4 PRE EQ SELECT STEREO GAIN RIGHT RIGHT STEREO INPUT L/R DIRECT CHANNEL AUX2 UNBAL LEFT FEEDBACK FERRETR Graphic EQ AUX 1-4 POST EQ SELECT LEFT/ MONO FADER BAL LEFT/ MONO OUT AUX3 Block Diagram-16FXTM, AAM 250TM & 32FXTM 20 MUTE/ CLIP SIG/ PFL AUX4 AUX5/EFX1 AUX6/EFX2 PFL EFX1 LEVEL MUTE BALANCE COMPUTER RIGHT FEEDBACK FERRETR Graphic EQ USB INTERFACE RIGHT/ MONO FADER UNBAL MEMORY RIGHT/ MONO OUT BAL AFL/ CLIP AUX 1 ASSIGN L/R AFL AUX1 SEND AUX1 OUT 1/2 AFL/ CLIP AUX1 3/4 LEFT OUTPUTS RIGHT AUX 2 AUX2 SEND AUX2 OUT AFL FROM AUX 5 AUX2 INPUT EFX2 PATCH LEFT OUTPUTS RIGHT EFX 1 PROCESSOR MUTE/ CLIP AFL FROM AUX 6 INT EFX2 RTN EXT PATCH INPUT EFX 2 PROCESSOR AUX 3 & 4 AUX EFX2 PATCH SIG/ AFL AFL/ CLIP AUX SEND T=IN R=OUT EFX2 LEVEL MUTE BALANCE ASSIGN L/R AFL AUX OUT 1/2 EFX2 RETURN 3/4 AUX1 AUX 5 & 6 AUX AUX2 LEFT/ MONO AFL/ CLIP AUX SEND AUX OUT AFL AFL AUX 5 TO EFX 1 AUX 6 TO EFX 2 RIGHT MUTE/ CLIP · · · ·· SIG/ AFL · ···· · · · · · ··· ···· · FX_ D B C D Sheet 2 A FXTM Series Specifications Inputs Function Microphone (150 Ohms) Input Gain (Ohms min) Setting 2. 2k Max Gain (60 dB) Min Gain (0 dB) Input Z Min* -76 dBu -16 dBu -56 dBu +4 dBu -26 dBu -6 dBu -36 dBu -16 dBu Input Levels Nominal** -56 dBu +4 dBu -36 dBu +24 dBu -16 dBu +4 dBu -16 dBu +4 dBu Max -40 dBu Bal/ Unbal Bal Connector XLR Pin 1 Gnd Pin 2 (+) Pin 3 (-) +20 dBu -20 dBu Bal +40 dBu +2 dBu Unbal +22 dBu +2 dBu Unbal +22 dBu 1/4" TS; Tip (+) Sleeve Ground 1/4" TRS; Tip (send) Ring (return) Sleeve Ground 1/4" TRS; Tip (+) Ring (-) Sleeve Ground 1/4" TS; Tip (+) Sleeve Ground 1/4" TRS; Tip (+) Ring (-) Sleeve Ground Line (10 k Ohms) 20k Max Gain (40 dB) Min Gain (-20 dB) Stereo Line (direct to L/R) 10k Max Gain (20 dB) Nominal Gain (0dB) Stereo Line (via channel) 10k Max Gain (20 dB) Nom Gain (0dB) Channel and Group Insert Return 22k N/A (0dB) Max Gain (10 dB) -16 dBu -16 dBu -6 dBu -16 dBu -6 dBu +4 dBu -6 dBu +4 dBu -6 dBu +4 dBu +22 dBu +12 dBu Unbal EFX2 Return 20k Nom gain (0dB) Max Gain (10dB) +22 dBu +10 dBu +20 dBu Bal Unbal RCA Jacks Media In 10k Nom Gain (0db) 0 dBu=0. 775 V (RMS) * Min Input Level (sensitivity) is the smallest signal that will produce nominal output (+4 dBu) with channel and master faders set for maximum gain.
