Pendulum Audio HZ-10SE Operating Manual Download Page 7

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.

Unpacking

The unit was carefully packaged at the factory to protect against damage in transit.   Nevertheless, be sure

to inspect the unit and shipping carton for any signs of damage that may have occurred during shipment.  If
there is any damage, notify us immediately for further instructions.  It's also a good idea to save the carton
and packing should you ever need to return the unit for repair.

The shipping carton should contain the following items:

• The HZ-10SE Main Preamp Unit

• Dual foot switch

• Preamp Module with connecting cable

• This Operating Manual

Initial Setup

The HZ-10SE's setup is rather straightforward. However, you may find it useful to refer to the block

diagram on page 16 to identify how the controls on the front panel of the Main Preamp Unit affect the signal
flow.

    

Hookup

•  Connect the 3 pin mini-connector end of the 18' cable to the Preamp Module.
•  Connect the male XLR connector end of the cable to the phantom-powered input labeled 'Preamp Module'

on the rear panel of the main unit. 

CAUTION:

   This input should be used only for the preamp module or

other  sources  equipped  to  use  or  block  the  phantom  voltage.  

•  Connect the Main Preamp Unit output via the 1/4" output jack on the rear panel to the method of

amplification you're using : i.e. high level (line) input of sound reinforcement system, studio mixing
console, or high level input of your amplifier, or even your stereo system. Or if you prefer, the main output
can also be used to drive a set of headphones.

Note:  The output jacks (Left, Right) allows either 

unbalanced

 or 

balanced

 line operation:

Unbalanced operation:   1/4" mono phone plug
Balanced line operation:   1/4" stereo (tip-ring-sleeve) phone plug
                                         

Tip = XLR pin 2,  Ring = XLR pin 3,  Sleeve = XLR pin 1.

•  Connect the input of the Preamp Module into the pickup output connector on your instrument.  Depending

on the version of Preamp Module you've selected, you will either plug the Preamp Module directly into
the instrument's 1/4' endpin jack (Endpin Jack version), or use a short cable between the instrument and
Preamp Module (Belt-clip version). Other versions of the Preamp Module, such as the HZ-10(I) implant
or the HZ-10(D) dual pickup module, come with detailed instructions on their installation, hookup and
use.  Refer to the instructions supplied with these modules.
