1. Fuse holder - Holds a 5A/250V fuse for 115 volt operation or a 2.5A/250V fuse for
230 volt operation
2. AC input - Connect the supplied standard 3-pin "IEC" plug here.
3. Send Pre - Use this 1/4" unbalanced jack to send signal to a professional outboard
effects processor.* Output level is approximately 0 dB to +4 dB and is pre-EQ and
pre-Shape but post-Volume control.
4. Return Pre - Use this 1/4" unbalanced jack to return signal from a professional
outboard effects processor.* Signal is returned before the EQ and Shape controls but
after the Volume control.
5. Send Post - Use this 1/4" unbalanced jack to send signal to a professional outboard
effects processor.* Output level is approximately 0 dB to +4 dB and is post-EQ,
post-Shape, and post-Volume control.
6. Return Post- Use this 1/4" unbalanced jack to return signal from a professional
outboard effects processor.* Signal is returned after the EQ, Shape and Volume controls.
7. Line Out - This standard unbalanced 1/4" jack provides a line-level (+4 dBu) post-EQ,
post-Shape and post-Volume output signal from the HA3000. You'll usually use this to
connect the HA3000 to additional slave amplifiers.
8. Preamp Out - This standard balanced XLR jack provides a -20 dBu level post-EQ,
post-Shape and post-Volume output signal from the HA3000. This is generally used to
send the sound of the HA3000 (that is, the equalized, shaped signal) to a PA system or
recording mixing console.
9. Ground Lift switch - Used to reduce any hum or buzz that may be present in the
Direct Out and Preamp Out signals (see #6 on page 3 and #8 above). When set to the
right, "Float" position, chassis ground is removed from XLR pin 1.
10. Speaker outputs - Connect any 4, 8, or 16 ohm bass cabinet(s) to these standard
unbalanced 1/4" jacks. WARNING: Because of the high power levels and low
frequency content of the signal generated by the HA3000, use only appropriately
rated speaker cabinets (at least 300 watts at 4 ohms) that are specifically designed
for bass instruments. The minimum impedance of all connected speakers must not
go below 4 ohms (i.e., don't plug in two 4-ohm cabinets!).
11. Fan - This variable speed fan provides vital cooling to your HA3000 (the hotter the
amp gets, the faster the fan blows!). Make sure that it is kept free of all obstructions and
that cool, fresh air is accessible at all times. Also, try to ensure that the HA3000 is used in
a dust-free environment.
* In-line effects (such as footpedals) intended for low signal levels should be placed
between your bass and the front panel HA3000 Input and not connected with the rear
panel Send/Return jacks.
