STRIPPED BARE WIRE
up to 3 gauge can be inserted through the hole in the binding post and held in place by
tightening the post knob. Additional tightening pressure can be achieved using the wrench provided in the slots
of the knob. Do not over tighten or the binding post may become damaged. Note that copper wire is malleable
and should not be initially over-tightened or the connection may eventually become lose and require further tight-
ening.

EXTERNAL ZONE MUTE CONNECTOR:
When any or all of the 4 zone mute pins (labelled "1", "2", "3" & "4") are connected to the common pin (Labelled "C")
the corresponding Zone will be muted.

STEREO BUS INPUTS:
There are two pair of daisy-chained RCA connectors for single-ended
bus
inputs. An input signal connected to one
Left input will appear at the other Left input connector. Likewise, an input signal connected to either Right Stereo
Bus Input will be present on the other Right Stereo Bus Input. This input has 20K Ohms input impedance.
REMOTE POWER TURN-ON
(LOCAL/EXTERNAL SWITCH)
To power-up the D65/130/250Z using an external control voltage supply a 4v to
12v AC or DC control voltage (at approximately 2mA minimum) to the ‘IN’ termi-
nals of the “Power-Up” connector. The front panel ‘Power’ switch needs to be off
for remote operation.
Use paired wire of 22 gauge to 18 gauge between the source device and the
D65/130/250Z. The amplifier will now power-up when the control voltage is pres-
ent.
Immediately following power up, the control voltage will appear at the ’OUT’ termi-
nals of the “Power-Up” connector for the control of other equipment.
Removal of the control voltage causes the D65/130/250Z to turn ‘off’ and the con-
trol voltage at the ‘OUT’ terminals is interrupted.
NOTE:
The ‘OUT’ terminals of the “Power-Up” connector are connected to the ‘IN’ terminals once the D65/130/250Z
has powered-up.
NOTE:
Each channel normally mutes momentarily during power up and power down sequences.
AC POWER INPUT
This is a high current plug for the power cord receptacle. Check that the voltage rating at the right of the connector con-
forms with your locality. With the front panel power switch in the off position, insert the power cord into the D65/130/250Z,
then plug the other end to an appropriate A/C power outlet.
The control current across the “OUT” terminals is determined by the
source
equipment. The carrying current of the
‘OUT’ relay is 2 amps. The D65/130/250Z itself draws less than 3 mA from the control current when operating. The
D65/130/250Z channel LED, when unlit, indicates no A/C mains power is present at the channel. If all channel LED
indicaors are unlit the D65/130/250Z probably needs only to be powered on. A group of 4 LEDs not lighting possibly indi-
cates a blown group fuse. When checking fuses, unplug the power cord. Use on the specified fuses for your operating
voltage.
