CONDENSED OPERATING INSTRUCTIONS Preamp Module • LEVEL CONTROL: The level sets the of signal that is sent to the Main Preamp Unit. The level is adjustable from ‘off’ to maximum. • GAIN CONTROL: The gain control is a screwdriver-adjustable trim control that sets the amount the guitar pickup output is amplified by the Preamp Module. -

FOUR BAND PARAMETRIC EQUALIZER • ON: Depressing the EQ pushbutton illuminates the red 'on' LED and puts the parametric equalizer into the signal path. Each of the four bands of the equalizer has three controls: • FREQUENCY: The Frequency control (left hand side) sets the center frequency the band acts on. The frequency ranges are: 35 - 400 Hz HI - MID: 800 - 8800 Hz... - Page 4 'mix' feature that blends the effect with the dry sound inside the effect unit (e.g. a multi-effects processor). Introduction The HZ-10SE is the first professional-quality preamp system designed specifically for acoustic instrument pickups. It consists of a 'front-end' instrument preamp (Preamp Module), a rack mountable Main...
- Page 5 When used with the current generation of high impedance transducers, magnetic pickups and/or mini-mics, the HZ-10SE Preamp System makes it possible to get clean, natural, balanced sound from your instrument - sound you thought could only be obtained in the studio.
- Page 6 In doing this, we also gain a few 'extras': • Portability: You can have all the benefits of an implanted preamp without modifying your instrument, and you can use it with all your acoustic instruments. • Level Control: By putting a volume/gain control within easy reach, the preamp module can be optimized for any pickup output, and allows you to adjust the instrument volume at your playing position.

First and foremost however, we made sure that each segment of the signal path was designed for exceptional audio performance, to insure that the HZ-10SE is as 'at home' in the studio as it is on stage. We think that paying attention to the details makes a big difference - one that you'll be able to hear each time you pick up your instrument. - Page 8 Unit: • As you strum your guitar, turn up the Input control on the front panel of the HZ-10SE until the 'signal' LED begins to flash. This indicates the signal level is at the lower limit of the normal operating range...
- Page 9 Using the Four Band Parametric Equalizer Why have we chosen to use a parametric equalizer in the HZ-10SE? Well, regardless of which pickup system you use, or how they're installed, certain overtones will be exaggerated at the expense of others. Only a parametric equalizer has the flexibility that is essential for restoring the natural harmonic balance of your acoustic guitar.
- Page 10 The HZ-10SE's parametric has four bands: LO, LO-MID, HI-MID, and HI. Within each band there are three controls; the FREQuency control (left hand side) sets the center frequency band is acting upon; the bandwidth control (center) determines how wide (...
- Page 11 (like your living room or home studio). This is the best way to judge the effect that various control setting are having on your sound. If you're planning to use the HZ-10SE onstage with a sound reinforcement system, setting up this way first is important: it will help you distinguish problems with the sound from your guitar and pickup system from deficiencies in the sound system.
- Page 12 • Lack of 'Clarity' Often, because of the pickup's response or placement, the guitar's lower midrange overtones get exaggerated. This causes your guitar to sound 'muddy' and lack definition. Use the LO-MID band (with a fairly wide bandwidth) to cut a few dB in the 400-1000 Hz frequency range. •...
- Page 13 Here's a quick way to test the shielding on your pickup: • Set up the HZ-10SE to hear your guitar at normal listening level with the EQ off. • Put the area of your guitar where the pickup is mounted about 12" from a fluorescent light (an ideal broadband noise source).
- Page 14 HZ-10SE. Be aware, however, that the quality of the 'dry' sound passed through the effect is often not as good as when the signal is passed directly through the HZ-10SE. If this is the case, turn the 'mix' control to output the only the 'effect' signals and use the HZ-10SE's MIX feature.
- Page 15 (or the front panel LEDs turned on) until the instrument ON switch is also depressed. This is done so the L and R Outputs of the HZ-10SE are muted completely when the Instrument switch is 'off'.
- Page 16 Although the best sound quality is achieved when using the phantom-powered Preamp Module and connecting cable, the HZ-10SE may also be used with a wireless system. Hooking up the HZ-10SE Main Preamp Unit to the wireless is done as follows: •...
