Line Input - YORKVILLE Elite EF Series Owner's Manual

4. Clip LED
The red Clip LED indicates that
the signal level is excessive and is
causing distortion. To reduce clipping,
turn down the mixer levels and/or the
Master Level controls.
5. Main In / THRU
(LINK)
The Main In / Thru (Link) connectors
allow additional powered cabinets to
be driven from a single source. You
can Link up to 16 EF-Series powered
cabinets! The Link jacks are also the
correct input to use when driving the
EF-Series powered cabinets with an
external mixer.
Tech Note: The Link jacks operate at line level (+4 dBu) to achieve full power. When operating
from signals that are not as strong, use the Line inputs of the first cabinet in the chain. The
Link jacks are high quality balanced inputs with very good common mode (hum) rejection. To
ensure maximum hum rejection, the proper balanced cables must be used.
User Tip: Jacks marked Link Output are connected in parallel with the Link Inputs and are
provided for convenience to connect downstream cabinets. Link inputs may also be used as
outputs and Link Outputs may be used as Inputs.
Note: A maximum of 3 EF-Series Control Panel mixers can be used when Linking EF-Series
powered cabinets.
6. Mixer On/Off
This switch turns the internal mixer 'on' or 'off.' When the Mic or Line inputs are used, this switch
must be set to the 'on' position. If these inputs are not being used, the mixer should be turned 'off,'
this will help prevent the mixer from contributing noise to the system. The internal mixer should not
be used when a source other than another EF-Series powered cabinet (or similar) is connected
to the LINK jacks. Remember, a maximum of 3 mixers, in a chain of cabinets, should be used! A
much larger number of cabinets may be used with the mixers disabled on the additional cabinets.

7. Line Input

Input
The Line inputs allow line level sources such as digital media players (laptops, tablets or smart
phones) and CD players to be connected. A Combi Jack (XLR + 1/4-inch TRS hybrid) and a 1/8-
inch TRS jack help provide great versatility. The 1/8-inch TRS input (RCA on REV1) is set up to
blend stereo sources into mono. The Line input is also balanced to help reject unwanted hum
(when balanced cables are used).
Note: A microphone may be connected to Channel 1's Combi-Jack but will have lower gain
compared to Channel 2's Mic input (Phantom power is also NOT available for this input).
Tech Note: Unbalanced operation - When connecting an unbalanced source to the balanced
inputs as on an EF-Series powered cabinet, the best chance for hum rejection is made by
running a balanced cable from the source to the input. The return connection should be
connected to ground at the unbalanced plug. The EF-Series powered cabinet does not connect
AC power ground directly to the input signal ground.
Control
The Line control adjusts the input volume level of devices plugged into the Line input.
Note: You can use the Combi-Jack and 1/8-inch (RCA on REV1) Line level inputs
simultaneously but the relative volumes need to be adjusted at the source.
