Installation of multiple units of  

The Director

May you stack units of The Director on top of each 

other without an air space in between?

The Director is a very energy efficient amplifier and emits 

little heat so air spaces between units, while always helpful, 

are not mandatory for a background music system. In addi

-

tion, the slots on the bottom of The Director coupled with 
those on the top produce a chimney effect for moving air.

May you daisy chain or y-cord audio and power trigger 

connections?

If you are using Bus #1, daisy chaining audio is easy as 

there are two sets of jacks, one of which can be used to drive 

the next amplifier. Also the impedances internal to The Di

-

rector on the other RCA jacks allow for using audio Y-cords. 

For power control, the easiest is to have an Ethernet con

-

nection to each unit. The 12 volt mini jacks are powered to 

turn on another unit when the main unit is on (not standby). 

If you need more than 15 milliamps current on the 12 volt 

output, use a relay to prevent over loading The Director. (The 
Director itself only takes 1 milliamp to turn on.)

What are the power requirements and BTU outputs of 

The Director?

There is more detailed information in the specifications 

section of this manual. In general, we feel a conservative, but 

real life design criteria is 1/8th power. This will be a quite 

loud listening level for most rooms and assumes all zones 

driven at the same time. You will be amazed at how cool The 

Director is at this level. One rule does not fit all situations, so 

apply your knowledge of the particular circumstances in

-

volved. Also, see the section below on unique rooms and SPL. 

How many units may I put on one 15 amp breaker?

It depends. Since an individual unit of The Director may 

draw a maximum of 1300 watts and you are limited to 1500 
watts per device by most codes, there should be a separate 15 
amp circuit for each. 

The Director Model D4400 will draw even more power 

than the Model D3400. Accordingly, a dedicated 20 amp 
service will allow you to get the most out of your new high 
powered amp under demanding conditions.
