Alternative method for connecting at Low Level from pre amplifier

In some circumstances it is not possible to use the high level method of connection, for

example when using active speakers. Instead of using the attenuator as shown on page 15,

connect as shown below using a “Y” adapter from the left and right pre amplifier outputs and a

single phono to phono interconnect from the “Y” adapter to one of the low level inputs on the

REL.

Only use this method if the pre amplifier has two separate outputs.

In the unlikely event that the second pre amplifier output is only a parallel connection to the

other then this method will cause a mono signal to be sent to the main amplifier(s) or active

speakers.

If in doubt then contact your dealer/distributor or the manufacturer of the pre amplifier for

advice.

If the pre amplifier only has one set of left and right outputs then do not use a “Y” adapter

from each channel to a single “Y” adapter to the REL, this will have the effect of causing a

mono signal to be sent to the main amplifier(s) or active speakers.

If the pre amplifier only has one set of left and right outputs then “Y” adapters can be used to

create a second set of left and right outputs. This extra set of left and right outputs should

then be connected to the REL using the attenuator as shown on page 15.
