The AUX IN (INPUT 2) line input on a front panel mini-jack connector (6) is summed in
parallel with the same channel from the back panel. It has the following wiring:
L channel > Tip
R channel > Ring
Ground > Sleeve
Stereo LINE inputs accept -10 dBV (0.31 V) line level signals from CD and DVD players,
multimedia devices, iPod
®
, MP3 players, radio tuners, TV receivers, etc. Turntables CAN NOT be
directly connected to this unit, because the PKUB has no RIAA preamp equipped input.
The line MIX INPUT is a direct access to the main mixing "bus". This input with 0dB (1V)
sensitivity is especially useful to interconnect e.g. two PKUB units or a PKUB and a SAM type mixer,
etc., therefore increasing the number of mixing channels and inputs.
5. OUTPUTS
The PKUB has a low impedance main amplified stereo output labelled OUT (20, 21) to
connect loudspeakers: 2 x 50 W RMS @ 4
Ω
.
Use special care when setting the mixer general output level, VOLUME (5), so that CLIP
indicators never remain permanently lit in the upper part of the VU-meters bargraphs (9), but only (and
at the most) at the rhythm of the sound sequence lowest frequencies.
The PKUB has a non amplified stereo auxiliary output labeled SUB/AUX OUT (18) with RCA
connectors. Its output level is proportional to the equipment's general volume setting. Next to this
output, a MONO/ST selector allows to choose for this signal and the amplified outputs a monophonic
format (sum of L and R channels).
The PKUB allows to bridge outputs. In order to do this, simply press the back panel MONO
switch and connect the output as silk printed.
The PKUB incorporates a MUTE (22) remote control that can be activated by an external
potential free contact, affecting all inputs. This control is especially designed to connect fire
detection systems or any other safety device. It is internally selectable as "NO / NC" (normally open
/ normally closed) by means of a jumper. See configuration diagram for more details.
The MUTE front panel red LED indicator lights up whenever the unit is muted by the MUTE
external contact or by the user operating the MUTE control on the front panel or on the remote handset.
