Acoustic Magazine

"..more features than you can shake a stick at."
Guitar Buyer

Headway is already a highly respected name for acoustic pickups and acoustic guitar amps. Now their EDB-1 direct blend pre-amp will strengthen their reputation further with acoustic musicians.





Key features

•Premium quality pre-preamplifier for any acoustic instrument, with low noise signal boosting and tonal shaping

•Powerfully effective and musically sympathetic EQ

•Two channel mixing option, via a choice of connectors, ideal for instruments with two separate pickups fitted, or combined pickup and microphone

•Phantom power option to condenser mic., or to active pickup system wired for external powering ( no battery inside instrument. )

•Battery or mains power

Detailed specs

The EDB1 (Sheer Acoustic Equaliser Direct Blend) is a multi-purpose, compact external pre-amplifier box of genuine pro-audio quality.

Players can completely shape their sound with the unit's 5-band interactive EQ, switchable input impedance and 3-way Range Switch, offering acoustic guitar, bass or violin settings, which cut unwanted low end tones, below the useable frequency range of the instrument.

The result is much less body handling noise, unwanted resonance and feedback, and less bowing noise for violinists. Feedback and other resonance problems are further tackled by a very effective, broad ranging tunable notch filter and a Phase Reverse control.

Inputs are Mono Jack, Stereo Jack and XLR, via two channels, which enable the user to blend in an extra pickup, or microphone and to can plug into them via one or two standard mono jack leads, a jack lead plus an XLR, or a stereo jack lead.

The Input Impedance Switches on each channel, allow you to optimise the voicing for any of the major pickup types, while a huge amount of extra levels can be applied via the gain controls and additionally by the master volume.

Phantom power is also available to jack-in and XLR inputs, making the unit friendly for use with quality condenser mics and instruments wired without need for a battery. Active pickups needing powering of course.

Outputs are via a balanced XLR D.I. out and a line out jack. Any earth hum, can be killed by pressing the Earth Lift Switch. The two outputs also allow the user to split the signal, such as between Acoustic Combo amp for stage monitoring and an out-front mixing desk.

Powering is via two 9v PP3 ( 6F22 ) Batteries, or via plug in DC Power supply.

Weight is 500g.







ACOUSWITCH IQ DI


DESCRIPTION:

The Acouswitch IQ DI acoustic guitar preamp opens up a new dimension in acoustic guitar pre-amplification and signal routing, offering an all-in-one solution for acoustic guitar players, whether used in stand-alone mode or as the control centre of a pedal board.

The Acouswitch IQ DI features:
*    an A/B-input switcher
*    a high-end preamp
*    a clean booster
*    a parametric EQ
*    an FX Loop switcher
*    and last but not least. professional quality DI signal routing.
 
German manufacturing and best brand components provide maximum reliability and optimal treatment of the electrical signal from your acoustic instrument, wether from a magnetic or a piezo pickup.

Uncompromising in sound, build quality and flexibility, our high-end acoustic guitar preamp will prepare you for any situation, be it in live performance or recording sessions.

FEATURES:

• A/B input switcher.

The Acouswitch IQ DI offers two high impedance inputs with discrete circuit design. If you connect two instruments to input A and B, the A/B footswitch allows you to toggle between the two. The signal from instrument A is routed to channel A and the signal from instrument B is routed to channel B. If only one instrument is connected to input A, the A/B footswitch routes this signal to channel A or channel B. The “MIX” switch located between input A and B allows you to combine and mix both channels.

•  High-end acoustic guitar preamp with parametric EQ and body contour control

Channel A of the Acouswitch IQ DI features a high-end preamp and a three-band EQ, designed for acoustic instruments, offering bass, semi-parametric mids with a broad frequency range (100 Hz to 6 kHz) and treble controls. The body contour control acts on both channels.

• FX Looper

The Acouswitch IQ DI offers two effect loops: a passive serial loop and a switchable, infinitely variable mixing loop enabling you to go from a completely dry signal, through parallel, on to serial looping. A phase-inverter switch ensures that any out-of-phase signals do not cancel each other out when in parallel mode. And a Tuner Out keeps the tuner out of the signal path.

• Clean booster

A footswitch and a volume control allow you to add a second high-end amplification stage, upstream of the mix loop. This allows you to feed tracking, or overdrive/distortion pedals, with an adequate input signal. If the mix loop is not in use, the booster serves as an extremely clean solo booster.

• DI box

The Acouswitch IQ DI acoustic guitar preamp can be used to send an output signal directly to a mixing console or recording unit. The high-quality components and features of the Acouswitch IQ DI (high-end preamp, ground switch, pre / post signal processing switch, pad for output attenuation) in combination with the Lehle True Sound technology make this acoustic guitar preamp an excellent DI box, whether you’re using it at a live gig or in the studio.

• Line mixer

The Acouswitch IQ DI can also be used as a line mixer. To do this, the return socket of the mix loop is used as the input and the ratio of this signal to the signals coming from inputs A and B is adjusted using the mix control.

Headway EDM-1 and EDB-2 Review



 

by Doug Young

Preamps are a useful, if not essential piece of gear for acoustic guitarists, providing an interface to a PA or amplifier as well as tone-shaping capabilities, and generally acting as a control centre for your sound. While most preamps have similar basic functions, their features vary widely, and guitarists often have varying requirements that may make one preamp or another a better choice. Headway, a UK company known for its pickups, recently introduced two preamps that fill different niches and offer guitarists some new preamp choices. I compared both models, the single-channel EDM-1 and dual-channel EDB-2.

Compact, Impressive Packages

Both preamps are impressively designed, packing most essential functions as well as some extras into extremely portable boxes. The dual-channel EDB-2 fits easily into a guitar-case compartment, while the EDM-1 (at less than half the size of the EDB-2) would practically fit in a shirt pocket. Both units have a robust feel, and are heavy enough to stay in place on a floor or desktop even with a guitar cord tugging on them. Both units can be mounted to mic stands, making it easy to place the controls at your fingertips. The smaller EDM-1 also comes with a belt clip.

The two preamps share some features, but differ in several ways that are important to understand. The EDM-1 is by far the simplest, with basic three-band EQ, volume, and notch filter as the main controls. One nice touch on the EDM-1 is that it can be powered via 48-volt phantom power from a mixing board. The EDM-1 also has three switchable input impedances, from one to 20 megohms, which allows you to match the impedance of the pickup you’re using. Because of its small size, the EDM-1 has a TRS ¼-inch output, but Headway provides an XLR adapter for connecting to a PA. Oddly, the unit is turned on whenever the output is connected (activating the battery when an input is plugged in is more common).

The EDB-2 is far more complex, offering five-band EQ and some flexible dual-input options that can be slightly confusing and require some explanation. Channel 1 is a mono input intended for a typical guitar pickup, although the input can take a TRS cable and optionally provide nine volts of power to the tip or ring (switchable), which is intended to be used to provide power to Headway’s line of pickups, such as the HE-4. The EDM-1 also supports this mechanism, even though it is a mono preamp. Regardless, Channel 1 recognizes a mono signal on the tip of a guitar cable.

The EDB-2 supports a mic via an XLR input for Channel 2, which provides 18 volts of (switchable) phantom power. In addition, there is a stereo input jack that can accept a TRS cable for a stereo dual-source pickup, which routes the tip to Channel 2 and the ring to Channel 1. One source of confusion is the way Headway supports pickup-and-mic systems that require power for a mic. To support such a system, you need to plug into the stereo jack and set the Phantom switch to route power to thetipof Channel 1, which has the side effect of providing power to theringof the stereo input! Headway devotes two entire pages of the manual to the company’s view that internal mics should be avoided at all costs, which may partly explain the convoluted interface. But the bottom line is that the preamp does work with these systems, as well as other dual-source pickup setups that don’t require power. The XLR mic input would also make the EDB-2 a natural choice for use with certain external guitar mics, such as the DPA 4099.

The larger size of the EDB-2 allows Headway to pack in a lot more controls, including an impressive five-band EQ and semiparametric notch filter. One shortcoming is that while you can control the gain of each channel of a dual-source pickup (or the mic input) separately, you have to choose between using EQ on one channel or the other, or on the overall mix. The notch filter can also only be used with one channel. In trying it out at home, I had no problem dialing in some very nice sounds even with this limitation, but on a gig, you would probably want to be able to EQ each source separately.

The EDB-2 also offers more flexible inputs and outputs than its smaller brother. In addition to the input options, the EDB-2 offers a post-EQ auxiliary input that—in a sign of the times—is labeled as an iPod input, but could be used with any additional sound source, such as a drum machine, and has both ¼-inch unbalanced and XLR DI outputs, so you can send one signal to your stage amp and another to a PA. The master volume affects both outputs. Unlike the EDM-1, the EDB-2 cannot be powered by external phantom power, but it does use 18 volts (via a pair of nine-volt batteries), which provides additional headroom.

Crystal-Clear Sound

Most preamps claim to be transparent these days, and the sound quality of these Headway preamps justifies that claim. Both units sound great, delivering crystal-clear sound that neither adds nor subtracts from the pickup sound, with no noise. But both units stand out by virtue of their small size and well-laid-out feature sets, including tone controls and notch filters. The EDM-1’s three simple controls are at musically useful frequencies (120 Hz, 590 Hz, 10 kHz), while the EDB-2 offers controls centered at 120 Hz, 590 Hz, 900 Hz, 2.8 kHz, and 10.5 kHz. The low and high midrange controls should be especially useful at taming most guitar pickups. In addition, the anti-feedback notch filter on the EDB-2 is actually a semiparametric EQ with an adjustable Q width of 0.5–5 and a frequency range from 50 Hz to 6 kHz (cut only). Because the EQ and notch filter have separate channel selectors, you could potentially use the notch-filter EQ to affect one channel, while applying the five-band EQ to the other channel or the overall mix.

I tried both units with a variety of pickups, including soundboard transducers from K&K and McIntyre, an L.R. Baggs Lyric, a Highlander active undersaddle pickup, a Seymour Duncan Woody magnetic pickup, and a custom K&K soundboard transducer plus internal mic setup. All pickups sounded excellent through both units. I appreciated the EDB-2’s more extensive EQ, especially on the magnetic pickup, and having both channel gain and overall master volume was handy for adjusting both the low-output McIntyre Feather and the high-output Highlander. But the simplicity and tiny size of the EDM-1 was also compelling, and its three-band EQ was all I really needed to dial in a good sound. Of course, the EDB-2’s dual channels and ability to provide power were essential for my dual-source setup, and I was able to get a usable sound in spite of not being able to EQ each channel individually. The impedance switches had no discernible effect on the sound of any of the pickups I tried, but it’s a nice option to have, and potentially useful with some setups.

Flexibility and Utility

In spite of a few quirks, both the EDB-2 and EDM-1 are impressive tools, with superb sound and an amazing set of features packed into their tiny boxes. The minuscule EDM-1 might be all many guitarists need, and it has the benefit of being simple and easy to use. The complexity of the EDB-2 introduces a bit of a learning curve, especially if you need to figure out the best way to use the single EQ with a dual-source system, but its extra features provide capabilities and options that rival far larger preamps. With either of these units mounted on a mic stand, you will have full control over your sound at your fingertips.
