• Remote Powering the PM351

A very useful feature of the PM351 is the ability to send the

12-15VDC power to the unit via the LINE INPUT ring con-

nection. Make sure the Mono/Stereo switch is in the MONO

position. Connect the 12-15VDC to the Ring of the TRS plug

as shown here.

ROLLS WILL NOT BE HELD RESPONSIBLE FOR DAMAGE

DONE TO THE PM351 AS A RESULT OF IMPROPER USE OF

THIS FEATURE. IF YOU ARE NOT SURE HOW TO DO THIS COR-

RECTLY, CONTACT A QUALIFIED SERVICE TECHNICIAN.

NOTE: This unit cannot be powered by standard 48 Volt

Phantom Power supplied by mixers, phantom power adapt-

ers etc. The current (amperes) is insucient to power the

PM351. Also, any voltage greater than 16 VDC will damage

the unit.

CONNECTION

• The LINE INPUT connects to either a 1/4" stereo or mono plug.

If this plug is Tip-Ring-Sleeve stereo and you're sending a stereo

signal to this jack, select the STEREO setting of the Mono/Stereo

switch. If the plug is Tip-Sleeve mono, select the MONO setting

of the Mono/Stereo switch. The MONO setting is also the proper

selection if you are phantom powering the PM351.

• The MIC INPUT connects to either a dynamic or condenser micro-

phone via a standard XLR cable. If you are using a condenser type

mic, you will need to power it via phantom power from the mixer

which connects to the MIC THRU jack. This jack will pass the phan-

tom power from a mixer on to the microphone.

• Connect the MIC THRU jack to the mixer or snake as necessary.

• The INSTRUMENT INPUT connects to a guitar preamp output,

keyboard, or any stereo or mono instrument level signal. Again,

select stereo or mono.

• The INSTRUMENT OUTPUTS are transformer isolated and con-

verts the high impedance INSTRUMENT INPUT signal to low im-

pedance so it can be sent down a balanced line. These signals may

then be plugged into an XLR input on a mixer or snake. Note that

the level of this signal may be too high for a mixer's microphone

input - you may experience distortion. In this event, turn down

the instrument connected to the PM351 INSTRUMENT INPUT, pad

the input to the mixer's mic input, or trim down the mic input.

Connect your headphones to the proper Headphone Output.

PM351 is designed for performers who want to

monitor their own sounds, such as their vocals

and instruments, with the main mix via head-

phones. It’s very popular with drummers who

need to mix a click track with a monitor signal.

Church choir singers love the PM351 to monitor

their voices over the musicians.

PWR: LED for in-

dicating power

is applied to the

PM351.

DC IN 9 - 15 VDC: For

connection to the

external Rolls PS27

power adapter.

MIC THRU: XLR

jack paralleled

(hard-wired)

to the MIC

INPUT jack for

pass-through

to a mixer or

other micro-

phone level

input device.

LINE INPUT: 1/4”

TRS stereo jack for

connection to a line

level source such as a

mixer monitor/auxil-

iary output, cassette

player output, CD

player output etc.

HEADPHONE OUT-

PUTS: 1/4” Stereo

jack, and 1/8” stereo

jack for connection to

stereo headphones or

earphones.

MONO/STEREO

SWITCH: Selects

whether the LINE

INPUT jack is mono

or stereo.

NOTE: When in

MONO mode, the

ring of the jack

may be used to

“phantom power”

the PM351. See

the next page for

details.

LEFT/RIGHT OUTPUTS:

Transformer balanced XLR

outputs from the Instru-

ment Input.

LINE LEVEL: Adjusts the level of signal from the LINE

INPUT to the headphone mix.

MIC LEVEL: Adjusts the level of signal from the MIC

INPUT to the headphone mix.

INST. LEVEL: Adjusts the level of signal from the INST.

INPUT to the headphone mix.

MIC INPUT:

XLR balanced

jack for con-

nection to a

condenser

or dynamic

microphone.

INSTRUMENT INPUT: 1/4”

TRS stereo jack for connec-

tion to an instrument or line

level signal such as a guitar

processor, keyboard, or

instrument preamp output.

MONO/STEREO

SWITCH: Selects

whether the INST.

INPUT jack is

mono or stereo.

GROUND LIFT: Switch for

disconnecting chassis

ground from pin 1 of the

Mic Input and Mic Thru.

GROUND LIFT: Switch

for disconnecting

chassis ground from

the XLR instrument

output jacks.

GROUND LIFT

The Mic Input and Mic Thru have a ground lift switch provided to lift the XLR pin 1 from chassis ground. The XLR Instrument Outputs also have

this feature. If you experience a "hum" on the microphone or instrument outputs, lifting the ground may elliminate the problem.

Setting the Mono/Stereo switch;

If the input to the LINE INPUT or INSTRUMENT INPUT is a Tip-Ring-Sleeve stereo signal, set the Mono/Stereo jumper for stereo operation.

If the signal to the LINE INPUT or INSTRUMENT INPUT is Tip-Sleeve mono, move the switch to connect the "mono".
