AC 9V/1500mA socket used to plug in the power cord. Before connecting the power adaptor, make sure the power switch located on the front panel is turned off. 2. BAANCED MASTE output X sockets connect the mixer to main amplifier using standard cables with X connectors. We recommend using balanced cables if the distance to your amplifier is more than three metres. 3. MASTE output CA sockets also connect to the main amplifier with CA plug cables. 4. ZONE output CA sockets allow the connection with CA plug cables of an additional amplifier to drive audio speakers in another room of the venue. 5. EC output sockets can be used to connect the mixer audio output through CA plug cables to the input of your recording unit (perhaps a laptop or DAT or Minidisc or other type of digital recorder), thus enabling you to record your mix. 6. PHONO / INE convertible CA inputs: The convertible CA inputs for CH2 and CH3 allow phono and line level equipment to be connected to the mixer. 7. PHONO/INE SWITCH: Flick the converter switch up to operate PHONO 1 or PHONO 2. Flick the switch down to operate through INE 2 or INE 4. 8. INE inputs: There are a total of six dedicated CA line inputs for this mixer, one for each of channels 1 to 4, and two for channel 5. 9. MIC 2 and MIC 3 inputs (on the rear panel) accept only 6.35mm (1/4 ) connectors. The microphone inputs accept both balanced and unbalanced microphones. 10. GND: Grounding screw located between the converter switches on the rear panel of the A2554 mixer. Note: The PHONO inputs only accept turntables with a magnetic cartridge. When using turntables, you will need to ground the CA cables by screwing in the grounding fork to the grounding screw GND. The stereo INE inputs only accept line level inputs such as a CD/DVD, DAT, MiniDisc, etc. 3
FIGUE 2. CHANNE INPUT FEATUES AND OUTPUT SECTION CONTOS: 4 2 1 3 14 3. CUE: A push button that sends an input audio signal to the headphones, even while that channel s fader is down. By connecting a set of headphones to the headphone jack, you can monitor any or all channels. When the CUE button is pressed, an ED will illuminate and the audio from that channel (and any others with the CUE button pressed) will be heard in the headphones. 4. Equalizer: Each channel has three EQ control knobs ( HIGH, MID, OW ) to adjust the tone of the input signal, whether MIC/INE/PHONO. 5. Fader: Each channel has a 60mm sliding fader to control that channel s audio volume level. Ideally, the channel GAIN should be set so that when the channel fader is at zero the MASTE VOUME will be set so that the EDs on the MASTE DISPAY VU meter are consistently hitting zero and not much more. OUTPUT CONTOS: 6 5 7 10 8 9 CHANNE INPUT FEATUES AND OUTPUT SECTION CONTOS: 1. Source Selector Switch: Determines which input source is active on that channel. Depending on the channel number, the input could be either a MIC or INE or PHONO input. 2. GAIN: otary control knob that sets the audio volume level gain on each channel. For low level inputs, the GAIN can be boosted as needed. 13 12 11 6. Assign: There are two rotary control ASSIGN switches on the left and right side of the cross-fader, each having five settings, one for each channel on the mixer. The left control allows you to direct channels 1,2,3,4 or 5 through the left side of the cross-fader. The right control allows you to direct channels 1 through 5 to the right side of the cross-fader. Ensure that you assign different channels to each side of the cross-fader. 7. CUE/PGM Fader: By moving the CUE/PGM fader control to the left you will be able to monitor the assigned CUE signal. Moving the control to the right allows you to monitor master program mix (PGM) output. Moving the fader control to the middle allows the headphones to carry a mix of both CUE and PGM signals. 8. CUE VOUME: Use the rotary CUE VOUME control knob beside the headphone socket to adjust the audio level without changing the overall program mix. 9. Headphones: May be plugged into the socket on the front panel, bottom right corner. CUE VOUME controls the audio level in the headphones. 10. ZONE VOUME: This knob determines the output signal level to feed into a second amplifier to drive speakers in a different zone to the main amp and speakers. 11. MASTE VOUME: Once you are comfortable with the sound level of your music mix from various active channels, you may adjust the main volume with the MASTE VOUME control knob. This rotary control determines the output signal strength that flows from the MASTE BAANCED OUTPUT (X) and the MASTE OUTPUT (CA). 12. BAANCE: This rotary control knob adjusts the master audio signal strength across the left ()-right () stereo spectrum. 13. MASTE DISPAY: The dual channel ED VU level meter indicates the program output level in db of the MASTE left and right stereo channels, as determined by the setting of the MASTE VOUME and BAANCE control knob. The cross-fader settings determine which input source reaches the Master output controls. 14. Power switch: Use this to turn the mixer off and on. Once all of your connections have been plugged into the rear panel, turn the mixer on by pressing the power switch. 4

DJ MIC 1: Plug your main DJ microphone into the DJ MIC 1 connection on the front panel, which is a combination X-phone jack input. 2. VOUME: This rotary control knob adjusts the audio level of the DJ MIC 1. 3. HIGH and OW knobs allow you to adjust the EQ or tone of this microphone. 4. COSS-FADE SECTION: The cross-fader allows you to mix from one channel s source to another. The A2554 features an assignable cross-fader which allows you to select which channel will play through either side of the cross-fader. The cross-fader in A2554 is removable, and if the need arises, the module can be easily replaced. Place the cross-fader in the centre and both assigned channels will reach the master output controls. 5. AUTO TAKOVE: The purpose of the AUTO TAKOVE switch is to allow the program playing to be virtually muted so that the DJ MIC 1 may be heard above the program mix PGM audio. The AUTO TAKOVE switch 5 controls DJ MIC 1 with three settings which operate as follows: When the AUTO TAKOVE switch is in the bottom position, DJ MIC 1 and TAKOVE mode are both off. When the AUTO TAKOVE switch is in the centre position, DJ MIC 1 is on and TAKOVE mode is off. The ED indicator glows when DJ MIC 1 is on. When the AUTO TAKOVE switch is in the top position, DJ MIC 1 is on and TAKOVE mode is on, and the volume of all sources except the DJ MIC 1 input is lowered by 16 decibels. 6. CHANNE 1: To bring this channel into the program output (PGM), you must first decide which line will be used. Toggle between INE 1 and MIC 2 on this channel using the line switch. Once you have selected the appropriate input, slowly slide the CHANNE 1 fader to a comfortable level. You can further modify the sound output of this channel by adjusting the rotary GAIN control above the channel fader, and the HIGH, MID, OW equalizer controls located to the left of the CHANNE 1 fader.
7. CHANNE 2: To bring this channel into the program output (PGM), you must first decide which line will be used. Use the line switch to toggle from PHONO 1/INE 2 to INE 3 on this channel. Once you have selected the appropriate input, slowly slide the CHANNE 2 fader to a comfortable level. You can further modify the sound output of this channel by adjusting the rotary GAIN control above the channel fader, and the HIGH, MID, OW equalizer controls located to the left of the CHANNE 2 fader. 8. CHANNE 3: (Similar to Channel 2) To bring this channel into the program output (PGM), you must first decide which line will be used. Use the line switch to toggle from PHONO2/INE 4 to INE 5 on this channel. Once you have selected the appropriate input, slowly slide the CHANNE 3 fader to a comfortable level. You can further modify the sound output of this channel by adjusting the rotary GAIN control above the channel fader, and the HIGH, MID, OW equalizer controls located to the left of the CHANNE 3 fader. 9. CHANNE 4: (Similar to Channel 1) To bring this channel into the program output (PGM), you must first decide which line will be used. Toggle between INE 6 and MIC 3 on this channel using the line switch. Once you have selected the appropriate input, slowly slide the CHANNE 4 fader to a comfortable level. You can further modify the sound output of this channel by adjusting the rotary GAIN control above the channel fader, and the HIGH, MID, OW equalizer controls located to the left of the CHANNE 4 fader. 10. CHANNE 5: See description under section heading CHANNE INPUT FEATUES. This channel operates in a similar manner to all the others, except that it has only INE inputs as sources (INE 7 / INE 8).
