INTRODUCTION

Thank you for choosing one of Phonic's many quality compact mixers. The AM1204FX and AM1204FX USBR compact mixers – designed by the ingenious engineers that have created a variety of mixers fantastic in style and performance in the past – displays similar proficiency that previous Phonic products have shown; with more than a few refinements, of course. The AM series features full gain ranges, amazingly low distortion levels, and incredibly wide dynamic ranges, just showing the dominance these small machines will have in the pro audio industry.

AM1204FX and AM1204FX USBR both feature four of Phonic's quality low-noise preamplifiers accepting microphone signals, as well as number of line-level 14 " phone jack inputs across four mono and two stereo channels. The AM1204FX and AM1204FX USBR are both adorned with studio-quality 32-bit digital effect processors that feature 16 unique effects, each of which has its own user-adjustable parameter. Featured solely on the AM1204FX USBR is a stereo USB audio interface, perfect for sending audio directly to any modern OSX or Windows based computer. Stereo audio can also be injected straight into your mix via the USB interface.

We know how eager you are to get started – wanting to get the mixer out and hook it all up is probably your number one priority right now – but before you do, we strongly urge you to take a look through this manual. Inside, you will find important facts and figures on the set up, use and applications of your brand new mixer. If you do happen to be one of the many people who flatly refuse to read user manuals, then we just urge you to at least glance at the Instant Setup section. After glancing at or reading through the manual (we applaud you if you do read the entire manual), please store it in a place that is easy for you to find, because chances are there's something you missed the first time around.

GETTING STARTED

1. Ensure all power is turned off on your mixer. To totally ensure this, the power supply should not be connected to the unit.
2. No input other than the one being set should have any device plugged in. This will ensure the purest signal is used when setting channels.
3. Set the level control of the channel you are setting to the 0 dB mark.
4. Disengaged the Mute button for the channel you wish to set.
5. Ensure the channel has a signal sent to it similar to the signal that will be sent when in common use. For example, if the channel is using a microphone, then you should speak or sing at the same level the performer normally would during a performance; if a guitar is plugged into the channel, then the guitar should also be strummed as it normally would be (and so on). This ensures levels are completely accurate and avoids having to reset them later.
6. Set the gain control on the channel so that the level meter indicates the audio level is around 0 dB.
7. This channel is now ready to be used; you can stop making the audio signal.
8. You can repeat the same process for other channels. Or not, it's your call.

AM1204FX USBR Features

Computer Connection

By simply connecting the USB cable provided along with your AM1204FX USBR to the device and your Personal Computer or Laptop, you are able to send DVD quality (16-bit stereo, with a 48 kHz sampling rate) signal to and from your mixer. By doing this, you are actually turning your AM1204FX USBR into a highly useful plug'n'play soundcard for your computer.

The USB sends an audio stream of the Main Left and Right (record out) signal of your mixer to the computer. You can use almost any dedicated Digital Audio Workstation (DAW) software to record the signal from the AM1204FX USBR mixer. You can also set the mixer as your default audio device.

The USB interface also returns the audio signal from your computer back to the 2T Returns, the signal of which is controlled by the 2T / USB Return control. If there are input signals from both the USBR interface and the 2T Return, the two signals are combined and controlled simultaneously by the 2T return control.

MAKING CONNECTIONS

Inputs and Outputs

1. Mic Inputs

These jacks accept typical 3-pin XLR inputs for balanced and unbalanced signals. They can be used in conjunction with microphones – such as professional condenser, dynamic or ribbon microphones - with standard XLR male connectors, and feature low noise preamplifiers, serving for crystal clear sound replication. The AM1204FX and AM1204FX USBR mixers feature four standard XLR microphone inputs for your convenience.

NB. When these inputs are used with condenser microphones, the Phantom Power should be activated. However, when Phantom Power button is engaged, single ended (unbalanced) microphones and instruments should not be used on the Mic inputs.

2. Line Inputs

This input accepts typical 1/4" TRS or TS inputs, for balanced or unbalanced signals. There are various numbers of these inputs depending which mixer you are using. They can be used in conjunction with

various line level devices, such as keyboards, drum machines, electric guitars, and a variety of other electric instruments.

3. Stereo Channels

AM1204FX and AM1204FX USBR mixers feature two stereo channels thrown in for maximum flexibility. Each of these stereo channels features two 1/4" TRS phone jacks, for the addition of various line level input devices, such as electronic keyboards, guitars and external signal processors or mixers. These stereo channels can also be used as mono channels, where the signal from any 1/4" phone jack plugged into the Left stereo input will cause the signal to be duplicated to the Right input due to the miracle of jack normalizing. This does not work in reverse, however.

4. AUX Returns

These 1/4" TS inputs are for the return of audio to the AM1204FX and AM1204FX USBR mixers, processed by an external signal processor. If really needed, they can also be used as additional stereo input channels. The feed from these inputs can be adjusted using the AUX Return controls on the face of the mixer. When connecting a monaural device to the AUX Return 1 and 2 inputs, simply plug a 1/4" phone jack into the left (mono) input, and the signal will appear in the right as well.

NB. When any device is plugged into AUX Return 2, the mixer's internal digital effect engine is then disabled.

5. AUX Sends

These 1/4" TS outputs may be used to connect to an external digital effect processor, or even to an amplifier and speakers (depending on your desired settings), to the mixer. The signal sent from the AUX outputs are fed from the master AUX send controls which themselves get their signals from the individual AUX controls on input channels.

6. Footswitch Jack

This port is for the addition of a non-latching type footswitch. This can be used to activate the digital effect processor. Tap the foot switch once to activate effects; tap a second time to turn them off once again.

7. Phones Connector

This stereo output port is suited for use with headphones, allowing monitoring of the mix. The audio level of this output is controlled using the Phones / Submix control.

8. Record Out

These outputs will accommodate RCA cables, able to be fed to a variety of recording devices such as digital recorders, tape recorders, and even laptop computers.

9. 2T Return

These RCA stereo inputs are used to connect the mixer with external devices, such as tape and CD players, or even Laptop computers, receiving a signal from another source and feeding it to the Main L-R mixing bus.

Rear Panel

10. Main L and R Outputs

These two ports will output the final stereo balanced line level signal sent from the main mixing bus. The primary purpose of these jacks is to send the main output to external devices, which may include power amplifiers (and in-turn, a pair of speakers), other mixers, as well as a wide range of other possible signal processors (Equalizers, Crossovers, etcetera).

11. Control Room Outputs

These two 1/4" Phone Jack outputs feed the signal altered by the Control Room/Phones level control on the face of the mixer. This output has extensive use, as it can be used to feed the signal from the mixer to an active monitor, for the monitoring of the audio signal from within a booth, among other possible uses.

12. ALT 3-4 Output

These unbalanced outputs are fed from the ALT 3-4 mix and can be used in conjunction with a large array of input devices, including signal processors, recording devices, monitor mixers, and so on. The ALT 3-4 mix is created by muting signals on channels 1 through 8.

13. USB Connector (AM1204FX USBR Only)

This USB connector can be used to connect the AM1204FX USBR to any modern Windows or Mac-based computer. Doing so will allow users to get a stereo signal both to and from the computer.

CONTROLS AND SETTINGS

Back Panel

14. Power Switch and AC Connector

The power switch, located on the rear of the mixer, is used to activate the mixer. But there's no point in activating the mixer if there's no power, therefore an AC power connector has been included to ensure your mixer gets the power it needs. Please use the power cable that is included with this mixer only.

15. Phantom Power Switch

When this switch is in the on position, it activates +48V of phantom power for all microphone inputs, allowing condenser microphones (well, the ones that don't use batteries) to be used on these channels. Activating phantom power will be accompanied by an illuminated LED above the left channel level meter. Before turning Phantom Power on, turn all level controls to a minimum to avoid the possibility of a ghastly popping sound coming from the speakers.

NB. Phantom Power should be used in conjunction with balanced microphones. When Phantom Power is engaged, single ended (unbalanced) microphones and instruments should not be used on the Mic inputs. Phantom Power will not cause damage to most dynamic microphones, however if unsure, the microphone's user manual should be consulted.

Channel Controls

16. Low Cut Filter (75 Hz)

This button, located on channels 1 through to 4, will activate a low-cut / high-pass filter that reduces all frequencies below 75 Hz at 18 dB per octave, helping to remove any unwanted ground noise or stage rumble.

17. Gain Control

These controls, found on each input channel, allow users to adjust the sensitivity of the input signal for the Line/Microphone input. The gain should be adjusted to a level that allows the maximum use of the audio, while still maintaining the quality of the feed. This can be accomplished by adjusting it to a level that will allow the peak indicator occasionally illuminate. All 4 mono channels feature this control.

18. Compressor Controls and Indicators

These control the onboard compressor function on mono channels. Turning this control up towards the 12 o'clock position will adjust the threshold and ratio of the compressor at varying degrees. Once you reach the 12 o'clock position, the control will then adjust the compression settings along with an onboard expander (or, in other words, a "compander"). The LED that accompanies this control will light up when the compressor is triggered. This control and indicator can only be found on mono channels.

19. High Frequency Control

This control is used to give a shelving boost or cut of ±15 dB to high frequency (12 kHz) sounds. This will adjust the amount of treble included in the audio of the channel, adding strength and crispness to sounds such as guitars, cymbals, and synthesizers.

20. Middle Frequency Control

This control is used to provide a peaking style of boost and cut to the level of middle frequency (2.5 kHz) sounds at a range of ±15 dB. Changing middle frequencies of an audio feed can be rather difficult when used in a professional audio mix, as it is usually more desirable to cut middle frequency sounds rather than boost them, thereby soothing overly harsh vocal and instrument sounds in the audio.

21. Low Frequency Control

This control is used to give a shelving boost or cut of ±15 dB to low frequency (80 Hz) sounds. This will adjust the amount of bass included in the audio of the channel, and bring more warmth and punch to drums and bass guitars.

22. AUX / EFX Controls

The AUX 1 and 2 controls allow the user to send the corresponding signal to the AUX 1 and 2 mixes, the final levels of which are controlled by the AUX Send controls on the main mixing panel. These signals are then sent to the corresponding AUX Send Outputs for use with amplifiers and studio or stage monitors, or simply in conjunction with external processors. AUX 1 features a pre-fader, pre-EQ signal, while AUX 2's signal is post-fader, post-EQ. The AUX 2 control doubles EFX control on the AM1204FX and AM1204FX USBR, adjusting the signal that is sent to the built-in Digital Effects Processor.

23. Pan / Balance Control

This alternates the degree or level of audio that the left and right side of the main mix should receive. On mono channels, this control will adjust the level that the left and right should receive (pan), whereas on a stereo channel, adjusting the BAL control will increase the left or right audio signals accordingly (balance).

24. MAIN / ALT3-4 Button

This button turns a mute on the corresponding channel on and off, stopping all audio from the channel input to the Main mix. When a channel is muted, this audio – which would normally be wasted – is redirected to the ALT 3-4 mix.

25. Peak Indicator

This LED indicator will illuminate when the device hits high peaks, 6 dB before overload occurs. It is best to adjust the gain of the channel so that the PEAK indicator lights up on intervals only, if at all. This will ensure a greater dynamic range of audio.

26. Level Control

This 60mm fader will alter the signal level that is sent from the corresponding channel to the main mix.

27. +4 / -10 Switch

This button, located on both stereo channels, is used adjust the input sensitivity of the corresponding channels. This will adapt the channel to external devices that use different operating levels. If the input source is -10 dBV (consumer audio level), it is best to engage the switch, allowing the signal to be heard. The +4 dBu level is suitable for professional audio signals, which are considerably higher than the consumer level. However, if you are unsure of the source's operating level, we suggest leaving the switch disengaged until you test the source's signal. You can then engage if necessary (if the level of the input signal is obviously too low).

USB Player / Recorder (AM1204FX USBR only)

28. USB Port

Connect your USB flash drive to this input. Once a drive is connected, the files will initiate and the main menu will appear on screen. Users are advised to format their USB memory sticks with the FAT-32 file system.

29. LCD Display

This display will display the track number currently being played. It also offers play, pause and record indicators as well as the current play/record time.

30. Play/Pause Button

Push this button to start and stop playback and recording of the currently displayed track. Starting a track after it is paused will resume the track from the point at which it was paused (in both record and playback mode). When in recording mode, push and hold this button to finalize recordings

31. |◀◀ and ▶▶| Back/Next Buttons

Pushing these buttons will allow users to skip back and forwards between tracks. When the menu is activated, these buttons are used to scroll through on screen options.

32. ■/MENU (Stop/Menu Button)

Push this button to stop playback or recording when applicable. Push and hold the button to access the USB recorder/player's main menu.

Digital Effect Section

33. Program Control

This control will allow users to select one of the 16 built-in digital effects of the AM mixer. The effect names that correspond with the numbers can be found on the top of the mixer's face, or in the digital effect table.

34. Parameter Control

Turning this control will adjust the one main parameter of the selected effect. Each effect's adjustable parameter can be found within the digital effect table.

35. Effects On Button and Indicators

Pushing this button will turn the built-in effect processor on and off. When the effect processor is activated, the corresponding LED will light up to indicate so. The uppermost LED is a Peak indicator. This will light up when the EFX signal reaches excessive peaks and should be lowered slightly. Please note that unlike many other buttons on the AM mixer, the EFX ON button will not latch down.

36. AUX Return Controls

These controls adjust the signal level of audio fed through the stereo AUX Return inputs to the main mix. The "To AUX 1" control found on the AUX Return 2 control adjusts the pre-fader level of the signal from the AUX Return to the AUX 1 Send mix. The button that accompanies the AUX 2 Return control allows users to determine whether the signal will be sent to the main stereo mix or the ALT 3-4 mix. When nothing is connected to the AUX 2 Return Input, the AUX 2 Return Control will be used to control the signal from the built-in effects processor.

37. Ctrl Room / Phones Control

This control is used to adjust the audio level of the Control Room feed, which is sent to both the Control Room outputs (for monitoring, acting as side fill or other purposes) and Phones outputs (to be used in conjunction with headphones for monitoring).

38. Control Room Source Buttons

These buttons allow users to select the source signals for the Control Rooms / Phones mix. Users are able to select from the Main mix, ALT 3-4 mix or the 2T Return mix.

39. AUX Send Controls

These controls adjust the final level of their corresponding AUX mixes (as taken from the AUX controls on each channel strip). This audio is then sent to the AUX 1 and 2 Send outputs found on the top of the mixer face.

40. 2T / USB Return Control

This rotary control adjusts the incoming level from the RCA 2T input connectors as sent to the main mix (and Control Room/Phones, if selected in the Control Room Source section). Unique to the AM1204FX USBR, this control is also used as the incoming USB level. All incoming signals through the stereo USB audio interface will be controlled by this control.

41. ALT 3-4 Submix Control

This fader is the final level control used to adjust the ALT 3-4 mix. This mix is created by muting input channels. Instead of simply losing the audio from these channels, it's redirected to the ALT 3-4 mix.

42. Main Fader

This 60mm fader is final level control for the main left and right audio feed, sent to the Main Left and Right outputs.

43. Level Meter

The mixer's stereo 11-segment level meter gives an accurate indication of when audio levels of the MAIN L/R output reach certain levels. It is suggested for the maximum use of audio to set the various levels controls to a level slightly below that which would cause the Peak LED to light up. This will help you get the most out of your audio without causing any distortion.

44. Phantom Power Indicator

This LED indicator will illuminate when the AM mixer's phantom power circuit is turned on.

45. Power Indicator

This LED indicator will light up when the AM mixer is turned on.
