6.8. BOOSTER LINE OUTPUT CONNECTION
This equipment provides two booster output sockets which can be used to drive a booster amplifier
in situations where more power is required. Connection is via RCA phone plug. (See above)
6.9. LOUDSPEAKER CONNECTION
This equipment provides four different types of loudspeaker output, these are 100 V, 70 V, 25 V
line and low impedance, you can only use one of these output at any one time, any attempt to use
two or more of these may result in damage to the amplifier.
6.9.1. 100 V Line
These loudspeakers are most commonly used in the Europe for PA distribution. When the amplifier
is at full output, 100V RMS will be present at the output terminals. Only use 100 V line
loudspeakers with this output. All loudspeakers are wired in parallel and the sum of the power
tapping of each loudspeaker must not exceed the rated output of the amplifier, ideally, due to the
nature of loudspeaker and transformer impedance's. It is advisable not to load the amplifier to
greater than 70 % of its rated output when using music sources.
1 & 2 Zones
In addition to the normal 100 V line output there are two sets of 100 V line terminals for 2
zones which can be selected using the push buttons on the front panel
6.9.2. 70 V & 25 V Line
This system is common in the U.S.A., it operates on exactly the same principals as 100 V line
except that at rated output the amplifier will have 70 V RMS or 25 V RMS on its output terminals.
6.9.3. Low impedance (8 Ω)
This output allows connection of standard low impedance loudspeakers, the minimum load
impedance must be 8 Ω, when two or more loudspeakers are used ensure that they are wired in
such a way that the load impedance is between 8 Ω and 16 Ω.
