Dean Markley UltraSound Acoustic DI Plus
The Dean Markley UltraSound Acoustic DI Plus direct box is a very powerful accessory for any acoustic guitarist. It lets you enhance your acoustic guitar sound for extra clarity and warmth when playing through an amplifier, PA system, or mixing board. It is perfect for gigging and your home studio, to bring out your guitar's personality and true tone.It looks simple, but it's loaded with first class functions and features that give it the versatility and performance you can't find in any other direct box in this price range.
It has features such as active bass and treble controls, to help you maintain your balance when changing from soft to aggressive strumming or picking and back. The Notch filter works well to cancel out any specific frequency that may be causing feedback or overload, and the EFX Loop is a real effects loop that lets you connect additional boxes and devices without degrading your guitar tone. We?ve included a summary of the DI Pluss features below, but the bottom line is the DI Plus lets you control and polish your acoustic guitar tone far beyond the limitations of onboard and EQ.
Features: INSTRUMENT INPUT: for all passive and active type pickup signals. When an instrument cable is plugged in, it switches On the 9V battery.
INSTRUMENT OUTPUT: a "parallel" jack, which can be used to send the "guitar/instrument signal" to an external tuner, guitar amp or other device, which can use an instrument level signal.
EFX LOOP: This is a real world "EFX LOOP". In an effort to save room, most of our competition uses a TRS jack (tip, ring, sleeve) and Y cable type system.
The DI+ is provided with two 1/4" jacks, one for "SEND" and one for "RETURN". Since the EFX LOOP interrupts the signal path it can be used as an insert point for a volume pedal, compressor, or tuner, if the tuner is equipped with a bypass switch.
SEND: The signal on the SEND jack is post-input gain and pre EQ. This means that you can use the SEND signal as an auxiliary unbalanced direct output. This signal is not affected by any of the panel controls with exception of the "INPUT GAIN" control.
RETURN: A plug inserted into the RETURN jack will interrupt the signal path. The signal on the tip of the plug inserted into the RETURN jack will be the signal that the DI Plus will process.
INPUT GAIN: The "INPUT GAIN" is not a volume control, rather this control sets the level of amplification applied to the input signal to boost it to a useable level. The reason this is adjustable is to accommodate a wide range of pickup devices.
BASS: The BASS control is an active control that adjusts the amount of cut or boost in the low frequency (150HZ and lower) range.
TREBLE: This is an active control that adjusts the amount of cut or boost in the high frequency (5kHZ) range.
NOTCH FILTER: ON/OFF - Enables or disables the NOTCH FILTER. FREQ. HZ This control works with the Notch Filter and sets the frequency (100-350HZ) of the 18db cut to control resonant feedback.
SHAPE: ON/OFF This toggle switch enables or disables the SHAPE control. The SHAPE control is a mid-range dip control which reduces the mid frequencies and boosts the high and low frequencies. This enhances the natural tone of an acoustic guitar.
PHASE: IN/OUT Changes the polarity of, or inverts the signal, which affects the way the guitar top is resonates in response to the loudspeakers. When the signals are out of phase with each other, low-end feedback is minimized. If you experience positive acoustic feedback on stage, flip the phase switch from its current setting to see if this will kill the feedback.
XLR LEVEL: This control adjusts the amount of signal sent to the XLR OUT jack.
LINE LEVEL: This control adjusts the amount of signal sent to the LINE OUT jack. 48V : (Phantom Power) This LED lights when there is 48V Phantom Power present on the XLR OUT jack.
POWER: This LED indicates the DI PLUS is ready to operate, and is ON when an instrument cable plug is inserted into the INPUT jack and there is power present from 9 volt battery, a 9 volt AC power adapter, or 48 volt phantom power.
LINE OUT: a standard unbalanced line level output signal. Use the "LINE LEVEL" control to adjust the signal level on this jack. This output can be used simultaneously with the XLR OUT jack for some creative signal routing.It accepts a standard instrument cable to go to a stage monitor amp or unbalanced Mic input on a mixer.
The Dean Markley UltraSund DI Plus gives you the sound enhancement you want for a full and natural acoustic guitar tone though any amp or PA system. It lets your acoustic electric guitar sound right, so you can relax and play at your best.
