① VZ THRU Jack (VITALIZER THRU)The input signal is split before being sent to the loop circuit,
and one branch is directly output via the VZ THRU jack after
being processed by the VITALIZER circuit. The low-impedance
output from the VITALIZER circuit is always available at the VZ
THRU jack, regardless of other switch settings. The VZ THRU
jack can be connected to other processing devices or a tuner,
for example.
② VZ IN Jack (VITALIZER INPUT)Signals input via this jack go through the VITALIZER circuit
before being sent to the unit’s main input (IN). When a plug is
plugged into the IN jack (3, below), the VITALIZER circuit is dis-
connected.
③ IN(Non-VITALIZERINPUT)Signals input via this jack go directly to the loop circuitry with-
out passing through the VITALIZER circuit.
④ S-1〜S-3 (SENDS 1〜3)These are the send jacks for loops 1 through 3. These outputs
should be connected to the inputs on your effect units.
⑤ R-1〜R-3 (RETURNS 1〜3)These are the return jacks for loops 1 through 3. The outputs
from your effect units should be connected to these inputs.
⑥ OUTOutput jack for the series loops (loops 1 ~ 3). The signal input
via the buffered (Bu-IN) or non-buffered (IN) input jack reaches
this output jack via the three series loops.
⑦ IN(LOOP4)Input to the separate loop (LOOP 4).
⑧ SND(N.C.)This is the send jack for the separate loop. This output can be
connected to the input of an effect unit. When the separate loop
is turned off the output from the send jack is muted. This jack
also functions as latching N.C. (Normally Closed) switch and
can be connected to an amplifier’s channel-switching control
jack for remote channel switching: when the loop is OFF the
jack is “closed”, and when the loop is ON the jack is “open”.
⑨ RTNThis is the return jack for the separate loop. The output from
your effect unit can be connected to this input.
⑩ OUT(N.O.)Output from the separate loop (LOOP 4). This jack also func-
tions as a latching N.O. (Normally Open) switch and can be
connected to an amplifier’s channel-switching control jack for
remote channel switching: when the loop is OFF the jack is
“open”, and when the loop is ON the jack is “closed”.
⑪ POWER（AC12VIN）The output cable from the supplied AC adaptor should be con-
nected here. Use ONLY the supplied AC adaptor.
⑫ MODESwitchPressing this switch alternately selects the PG (PROGRA )
and DIR (DIRECT) modes.
⑬ STORESwitchThis recessed switch is used to store loop settings when pro-
gramming loop combinations to be instantly recalled in the
PROGRA mode.
⑭ DC9VOUT（Provolt9）These four DC power output jacks (center-minus) provide a
compact, convenient power source for your 9-volt effect units.
It is possible to supply up to 400 mA for each 100 mA. (i.e. the
total power consumption of the connected effect units must be
less than 400 mA).
2. Setup and Operation3TheprocedurebelowsetsupthePEC-4Vforbasic3-series-loopoperation.2-1. Preparation (Making the Connections)[Caution]: Make sure the a plifier’s power is OFF when aking initial connections. The a plifier’s power should be turned on last.
1) Connect the effect units to the PEC-4V loops. The loop send connector (S-1, S-2, or S-3) connects to the effect unit input, and the
effect unit output is connected back to the return connector (R-1, R-2, or R-3) of the same loop. For example: S-2 -> Effect -> R-2.
2) Connect the DC9V outputs from the PEC-4V to the DC power inputs of your effect units as required (refer to section 4-5 “DC9V
Outputs” fordetails and precautions).
3) Connect your instrument to the VZ-IN (VITALIZER INPUT) or IN (DIRECT INPUT) connector.
4) Connect the OUT connector to the amplifier’s input. If you will be using a tuner you can also connect the VZ-THRU (VITALIZER THRU)
output to your tuner’s input.
5) Connect the supplied AC adaptor to the PEC-4V and to a convenient AC outlet to power up the unit: the PG 1/L1 indicator will light.
Turn on any effect units that need to be powered up as well.
6) Turn the amplifier on. Raise the amplifier’s volume a little, then raise the volume control on your guitar or bass and play. If you get no
sound at this point go back and re-check the connections. When you’re getting direct sound, the next step is to check your effect
unit connections.
7) Press the rear-panel ODE switch to select the DIRECT mode. The green DIR LED will light. In this mode you can use the PG 1/L1~
PG 3/L3 switches to individually switch each loop on or off to check operation of the connected effect unit.
Example:
Suppose you have a compressor connected to loop 1, an overdrive pedal connected to loop 2, and a delay effect connected to loop 3. Turn each loop on
and off in sequence and make sure that the corresponding effect is functioning properly. If, for example, you get no sound when you get to the overdrive
pedal connected to loop 2, check the connections carefully in case one of the plugs is not properly inserted.
