Yorkville Sound ES700P Hi Frequency Cutoff Control, Subwoofer Level Control, Input Ground Switch

1.Hi Frequency Cutoff Control

This control varies the frequency at which the ES700P rolls off the high frequencies. This provides part of a crossover function. This crossover function also combines with the natural low frequency

roll off inherent of the full range cabinet (when the ES700P is not used with an élite processor). This control should be set to the closest possible frequency to 20 Hz below the crossover point that the full range speakers processor uses as it's crossover point.

This Subwoofer may be driven from Speaker Level		0
or Line Level signals. If an élite processor is used,
this Subwoofer should be plugged into the SUB
output of the processor. The High–Frequency
Cutoff should be set to 150-Hzand the Input Level
should be set to LINE. For Line		-3	dB
Level operation a balanced (Tip
Ring Sleeve) cable should be
used. If the system is being	INPUT GROUND
operated without a processor,	UNGROUNDED
this Subwoofer can be	GROUNDED
connected to the output of the	INPUT LEVEL
power amplifier as shown in the
diagrams and the Input Level	SPEAKER
should be set to SPEAKER. If	LINE
none of the equipment has a U-
ground, the INPUT GROUND
should be set to GROUNDED.
Otherwise the INPUT GROUND
should be set to the position that	LEFT(mono)
best minimizes the hum.		INPUT

the subwoofer gain above +12 is only appropriate at low operating level.

2. Subwoofer Level Control

The subwoofer level control adjusts the amount of bass added to the sound system by the ES700P. This adjusts for the relative sensitivity of the companion full range speakers and the desired system frequency response. This control should be set by listening while operating at a medium level and then not changed. It is not possible to set this control properly at high levels since the limiter is determining the output level. Setting the level too high will over load the circuitry causing a loss of bass dynamics. The level control should not be set above the 9 o’clock position except when operating at low levels. For most applications the control should be set between 0dB and +20dB.

A setting of 0dB on the SUBWOOFER LEVEL control is the correct starting point when setting up a sound system. From there the sound can be adjusted for best sound. The 0 dB mark refers to the setting that will give full power when the line input is used and the input signal is at a level of +4 dBV. This also is the setting to give a sensitivity of 2.83 Vrms (1 watt 8-Ohms) for 100 dB

3. Input Ground Switch

The ES700P expects the source feeding it to be grounded. A system comprised entirely of ungrounded equipment may cause the ES700P to hum or buzz. If you have a buzz or hum problem, try setting the switch to the "GROUNDED" position. The switch should otherwise be left in the "UNGROUNDED" position. Do not use the grounded position with an amplifier operating in bridged mode or when the sleeve of the input signal is live.

4. Input Level Switch

A switch is provided to switch input levels between speaker level and line level. The switch should be set to speaker level when the ES700P is fed from the output of an amplifier or powered mixer. The line level position is for when the ES700P is fed a signal from a processor, electronic crossover or the output of an unpowered mixer. When using the line level mode the use of balanced (Tip, Ring, Sleeve) cables will reduce the sensitivity to hum and buzz.

AT HIGH POWER LEVELS WHEN THE LIMITER IS OPERATING INCREASING THE SUBWOOFER LEVEL CONTROL WILL NOT INCREASE THE OUTPUT. DO NOT INCREASE SETTING WHILE OPERATING AT HIGH LEVELS.
