Channel Islands Audio E 200S User manual

E•200S Dual Mono Amplifier
Thank you for purchasing the E•200S audio power amplifier.
Our E series amplifiers represent the latest in Class D amplifier technology, and offer many advantages
over traditional amplifier designs:
•Flat frequency response and phase into any conventional speaker load
•Low distortion which is flat vs frequency
•Ultra low output impedance for excellent control of the loudspeaker
•High efficiency, which results in lower power consumption, low operating temperature, and high
reliability
•Compact & light weight package
Handcrafted in USA

Design
•Power
The internal design of the amplifier consists of a power control circuit consuming less than a ½ watt of
power . When turned on, this circuit feeds dual mono switched-mode power supplies… one for each
channel. The on/off function can be controlled by the front panel switch or via the 12V trigger input on
the rear panel.
•Audio Circuit
Input signals are connected via rear panel mounted RCA (single-ended) or XLR (balanced) jacks into
individual differential pre-stage circuits with on-board regulation. Output of this circuit is then coupled
to updated UcD Class D stages. These new & improved output circuits incorporate many advances found
in the Hypex NCore technology.
Amplifier outputs are conveniently located on the rear panel. Speaker connections can be made in a
variety of ways via the insulated 5-way binding posts.
The compact machined aluminum chassis provides heat dissipation for the direct-mounted power
supply and audio output circuits. Due to the high efficiency of the circuits, the chassis will only be warm
to the touch under normal conditions.
•Protection
The E series amplifiers are equipped with a variety of fault protections including DC, over-voltage, and
short-circuit. AC Mains Fuse protection is also provided and easily accessible above the power inlet.

Connection
Before making any connections to the amplifier, find a suitable location which allows air to circulate
around the chassis. Never place directly on top of/or underneath another component.
•Loudspeakers
Always make connections to the loudspeakers first. We suggest using heavy gauge cables to keep the
output impedance low. The 5-way binding post can accept a variety of banana plugs, spades, pins, or
bare wire… hand- tighten only as the use of pliers/tools can damage the insulators.
•Signal Input
The input signals can be connected using balanced (XLR) or single-ended (RCA) sources. When using
balanced, the toggle switches are placed in the “up” position. For RCA the switches are placed in the
“down” position. The switches control grounding for lowest noise and are not “input” switches.
ONLY 1 PAIR OF JACKS CAN USED AT A TIME
•12V Trigger Input
If your source/pre-amplifier has a 12V Trigger Output (such as our PLC-1 Passive Line Controller), you
can connect it to the Trigger Input of E200S using a compatible cable (3.5mm connectors).
This will allow control of the On/Standby function by the trigger source.
For 12V trigger operation, leave the front panel switch in the “off” position.
•AC Mains Power
AC Mains connection should always be made after all other connections. Once the AC has been
connected, turn the source volume to a low level before turning on the amplifier. Once enabled, there
will be a short turn-on delay of 2-3 seconds before the power indicator illuminates and the amplifier is
ready to play music.
Set the desired playback level and enjoy the music!
