1. Input connectors
Connect the input source to these electronic balanced connectors using either XLR or
1/4” TRS plugs. The 1/4” TRS and XLR plug configured as follows : Pin 2 (Tip) hot, Pin
3 (Ring) cold, and Pin 1 (Sleeve) ground. We recommend the use of balanced three-
con- ductor cabling wherever possible. Unbalanced two-conductor 1/4” plugs can
also be inserted into these inputs, but you will get better signal quality and less outside
noise and hum if you use balanced lines. Stereo signal should be connected to both
the Channel 1 and Channel 2 input jacks , however , when operating the Ei Series in
Bridged Mono or Parallel modes, use the Channel 1 input jack only.
2. 5-way Binding Post
Connect each channel of the Ei Series to 4 ohms or 8 ohms loudspeakers.Two pairs of
5-way binding posts are provided for each.channel, so that paralleling of speakers is
pos- sible.Connection to the binding posts can be made with bare wire, banana plugs,
or spade lug terminations.
3. Speakon output connectors
You can use these to connect each channel of Ei Series to 8 ohms or 4 ohms loud-
speakers.
4. Circuit breaker
AC BREAKER RESET
If the amplifier shuts off after a long burst of power, turn off the AC switch and check
the circuit breaker.The button can be pressed back in after a 30 second cool-down
period.If the breaker trips repeatedly,the amplifier may need servicing.
5. AC input
( E3i / E5i / E7i)
IEC connector for AC power cable. Con-
nect the supplied heavy-gauge 3-pin IEC power cable.
6.Fan
This is a variable speed cooling fan. Cooling air enters the amplifier through the air
ports located on front of the amplifier chassis, Be sure not to block these
ports when installing the amplifier or other associated equipment.
