Hill Audio ZPR-2820, User Manual

Page: 15 / 21

FUNCTIONAL DESCRIPTION
The ZPR-2820 is a zoning mixer which allows to connect up to two microphones and 8 stereo
sources to a total of 6 inputs. The two microphones have a dedicated equalizer and an automatic
talkover function which provides microphone priority over program material; the stereo inputs have
faders and thus allow live mixing of the input signals. One of the stereo inputs is balanced,
specifically catering for connections to the output of a stage mixer, thus making the ZPR-2820 a
perfect centre piece of a small hospitality venue sound system with occasional live music. The
main output is a stereo output carrying the mix of the input channels; an additional stereo zone
output can either carry the same signal as the main output or any of the input signals directly. A
prelistening section completes the user interface, while remote muting and emergency signal
replay facilitate the use in installed sound systems.
1.
AC inlet and fuse holder . Use the supplied AC cord to connect the unit to AC mains. Make
sure voltage and frequency stated and set on the unit comply with your local AC supply. The
fuse can be accessed by the small drawer at the AC inlet. To change the fuse, unplug the AC
cord first, pull out the fuse drawer and replace the fuse ONLY with a fuse of the SAME
voltage and rating. If the fuse blows again after replacement, hand over the unit to qualified
service personnel.
2. AV voltage Selector switch . Switches the AC supply voltage between 110/115V and
220/230V AC. See previous chapter for details.
3. Stereo main output . This is a balanced stereo XLR output carrying the main output signal
controlled by (34)
4. Stereo Main Output . This is an unbalanced RCA output carrying the same signal as output
(3).
5. Stereo Main Output . This is a balanced terminal block output carrying the same signal as
output (3).
6. Maximum level setting for Stereo Main output . This control allows to limit the maximum
level at the output (3) / (4) / (5) in order to match the connected sound system. Adjustment
made on this control will not be displayed by the output level meter (40). Adjustments shall
be made with a small screwdriver. Note that the total angle is 300 degrees; do not apply
excessive force with the screwdriver.
7. Record output . This is an unbalanced stero output carrying the same signal as the main
outputs (3) / (4) / (5), but not influenced by the main volume control (34). This is normally
used for recording the output to an external tape, CD or memory device.
8. Stereo zone output . This si a balanced stereo XLR output carrying the main output signal
controlled by (38).
9. Stereo zone output . This is an unbalanced RCA output carrying the same signal as output
(8).
10. Stereo zone output . This is a balanced terminal block output carrying the same signal as
output (8)
11. Maximum level setting for Stereo Zone output . This control allows to limit the maximum
level at the outputs (8) / (9) / (10) in order to match the connected sound system.
Adjustments made on this control will not be displayed by the output level meter (40).
Adjustments shall be made with a small screwdriver. Note that the total angle is 300 degrees;
do not apply excessive force with the screwdriver.
12. Equalizer for Zone output. This is a 2-band stereo equalizer to adjust the frequency
response of the output. Adjustments shall be made with a small screwdriver. Note that the
total angle is 300 degrees; do not apply excessive force with the screwdriver.
