. QUICK STAT This is the fastest way to get something out from your APM Series, if you have a keyboard and a microphone. a. Plug the microphone into Channel MIC IN. b. Turn down AUX and EVE controls on the input channel. c. Put the EQ controls on center position. d. Connect passive cabinets to the rear speaker cabinets. e. Turn on your APM Series. f. Sing or speak into the microphone with normal volume and adjust the channel EVE control of half. g. If you like, you can adjust the EQ at this stage. h. The ED on the Master ED meter should flash only occasionally, otherwise you will hear distortion. If this ED is not active and you still hear distortion, please turn down a little the input EVE control or reduce the output level of your source instrument. i. Connect your stereo keyboard into channel 9/ and repeat the sequence.(for APM) Connect your stereo keyboard into channel /4 and repeat the sequence.(for APM6) Here you are. It is your first gig with your APM Series.

SPOTIGHT 4. CONTO EEMENTS Mono and Stereo Input Channels The MONO MIC/INE Channels Your APM is equipped with ( for APM6) low-noise microphone preamplifiers with optional phantom power, 4 of Gain and over of S/N ratio. You can connect almost any type of microphone. Dynamic microphones do not need phantom power. Use phantom power only with condenser microphones but make sure that the phantom power button is disengaged before connecting the microphone. Phantom power will not damage your dynamic microphones, so make sure to read the microphone instructions manual before engaging phantom power. Use switch (4) to activate/deactivate phantom power. These channels are also equipped with /4" TS balanced/unbalanced INE-IN plugs to connect line-level instruments such as keyboards, drum machines and effect devices. MONO Channel INSET This is where you connect external sound processors such as compressor-limiter, equalizers, etc. The insert point is available on the first MIC ( for APM) channels only. For the other channels you can always insert the processor in between the sound source (such as keyboard or drum machine) and the APM input. The Insert sockets can be used as direct-outs to feed the input of a 4-track tape recorder. MIC INE IN A/UNA INSET STEEO INPUTS These are Channel 9/ and / (Channel/4 and /6 for APM6). They are organised in stereo pair and provided with /4" TS phone sockets. If you connect only the left jack, the input will operate in mono mode, that is the mono signal will appear on both input channels. You can use these inputs with a stereo keyboard, drum machine, etc. 4 +4 Volt Phantom Power It is available only to the X MIC sockets. Never plug in a microphone when phantom power is already on. efore turning phantom power on, make sure that all faders are all the way down. In this way you will protect your stage monitors and main loudspeakers. INE IN 9 EFT INE IN IGHT OFF ON PHANTOM +4V (CH -4) 4
SPOTIGHT 4. CONTO EEMENTS MONO IN GAIN This control is provided with different indications: One is for the MIC and the other for INE levels. When you use a microphone, you shall read the MIC ring (~-4); when you use a line level instrument, you shall read the INE ring (+~-). For optimum operation you shall set this control in a way that the PEAK ED() blinks only occasionally in order to avoid distortion on the input channel. 6 EVE SET ED This ED will help you to detect the input level immediately. In this case the research of the fault will become much faster! 7 OW-CUT utton y pressing this button you will activate a 7 Hz low frequency filter with a slope of per octave. You can use this facility to reduce the hum noise infected by the mains power supply, or the stage rumble while using a microphone. 6 7 6 EVE SET MIC INE -4 + - EVE SET OW CUT 7Hz /Oct + - GAIN GAIN 9/ STEEO IN GAIN When you use a line level instrument, you shall read the ring (+~-).For optimum operation you shall set this control in a way that the PEAK ED() blinks only occasionally in order to avoid distortion on the input channel. EQUAISE There are bands EQ with sweepable MID on all mono input channel- (channel- for APM6): HI, MID and OW band. There are 4 bands fixed frequency EQ on the stereo channel 9- (channel-6 for APM6): HI, HI-MID, MID-OW and OW band. All bands provide up to of boost or cut.

SPOTIGHT 4. CONTO EEMENTS 9HI If you turn this control up, you will boost all the frequencies above khz (shelving filter). You will add transparency to vocals and guitar and also make cymbals crispier. Turn the control down to cut all frequencies above khz. In such way you can reduce Sibilances of human voice or reduce the hiss of a Tape player. MID This is a peaking filter and it will boost/cut frequencies from Hz to khz depending on the position of the MID freq control. This control will affect especially upper male and lower female vocal ranges and also the harmonics of most musical instruments. HI-MID This control gives you up to boost/cut at khz. It is useful for controlling voice. It can accurately polish your performance via adjusting this knob. MID-OW This control gives you up to boost or cut at Hz. OW If you turn this control up, you will boost all frequencies below Hz. You will give more punch to bass drum and bass guitar and make the vocalist more "macho". Turn it down, you will cut all the frequencies below Hz. In this way you can avoid low-frequency vibrations and resonance thus preserving the life of your woofers. 4 AUX SENDS evel Control These four controls are used to adjust the level of the respective signal sent to AUX bus, AUX and AUX can be switched to PE/-FADE via the PE/ button, so, generally, they can be used for monitor application and effects & sound processors Input. AUX and AUX4 are configured as -Faders. In this typical compact unit, excluding sending out the signal directly to the external effect or processor equipment, AUX SEND4 can also be assigned to the internal onboard effect module. 4 AUX - + PE - + PE DFX (EXT) - + 4 4 DFX (INT) - + - + A 6 - + - + - + AUX PE PE DFX (EXT) DFX (INT) A EFT IGHT EFT IGHT MUTE MUTE 7

Keep this control in center position, then the signal will be positioned in the middle of stage. 6 MUTE Switch Each channel is equipped with the MUTE switch. Pressing this switch is equal to turning the fader down, which can mute the corresponding channel output except for the PE AUX sends, channel INSET send. 7 PF (pre-fader listen) Switch Each channel has a PF switch which will send a signal from a post-eq pre-fader location to the PHONES jack. Use this when you wish to use the headphones to monitor only a specific channel. Moreover, you can monitor a channel no matter the channel is lowered or the MUTE switch is on when this PF switch is engaged. This will not affect the signals that are sent to the ST bus and AUX buses. PEAK ED Inside your APM Series the audio signal is monitored in several different stages and then sent to the PEAK ED. When the ED is red illuminated, it warns you that you are reaching signal saturation and possible distortion, then you should reduce the input level for avoiding distortion. 7 - PF PEAK 9 FADE This fader will adjust the overall level of this channel - - - and set the amount of signal sent to the main output. 9 - -4-6 Master Section -TACK IN/OUT - TAPE IN Use the Tape input if you wish to listen to your mix from a Tape ecorder or DAT. - TAPE OUT These CA jacks will route the main mix into a tape recorder. -TACK IN/OUT TAPE IN TAPE OUT

. INSTAATION AND CONNECTION Ok, you have got to this point and you are now in the position to successfully operate your APM Series. However, we advise you to read the following section carefully to be the real master of your own mix. Not paying enough attention to the input signal level, the routing of the signal and the assignment of the signal will result in unwanted distortion, a corrupted signal or no sound at all. So you should follow this procedure for every single channel:. Turn down all Input and output gain controls.. Connect phantom powered microphones before switching on the +4 Volt phantom power switch.. Set the output level of your APM Series or the connected power amplifier at no more than 7%. 4. Position EQ controls on middle position.. Position panoramic (PAN) control on center position. 6. Increase the input gain properly for maintaining the good headroom and ideal dynamic range. 7. Depending on the actual application, turn slowly the input and output level controls for obtaining the maximum gain before distortion.. Now repeat the same sequence for all input channels. The main ED meter could move up into the red section. In this case you can adjust the overall output level through the main mix control. Audio Connections You can connect unbalanced equipment to balanced inputs and outputs. Simply follow these schematics.
