Introduction

Congratulations on your purchase of the Samson CL7 studio condenser. The

CL7 features a large, 1.1-inch, ultra thin diaphragm capsule which faithfully

reproduces a variety of sound sources including vocals, acoustic instruments

and overhead cymbals, to name a few. The extended frequency and fast tran-

sient response insures an accurate reproduction with linear characteristics from

bottom to top.

In these pages, you’ll find a detailed description of the features of the CL7

Studio Condenser Microphone, as well as step-by-step instructions for its setup

and use, and full specifications. You’ll also find a warranty card enclosed—

please don’t forget to fill it out and mail it in so that you can receive online tech-

nical support and so we can send you updated information about these and

other Samson products in the future.

With proper care, your CL7 will operate trouble free for many years. We recom-

mend you record your serial number in the space provided below for future ref-

erence.

Operating the CL7

Powering the CL7

The CL7 is a condenser microphone and therefore needs to be operated by

connecting a phantom power supply. Phantom power is standard on most quali-

ty mixers, outboard mic-pres and hard disk recorders. If necessary, an external

phantom supply can also be used. The CL7 receives the phantom power direct-

ly from a mic cable when connected to a mixer or other microphone input that

includes a phantom supply. The power is sent OUT of the microphone INPUT,

riding silently along with the audio signal. (Fairly mysterious, eh?) Most mixers

have a switch to engage the phantom power so be sure to check that the phan-

tom power is on.

Setting Up the Signal Level

When connecting the CL7 to a mixer or recorder input, be sure that the input is

of microphone level. Also, be sure that the phantom power is engaged as

explained the previous section “Powering the CL7”. Most mixers and recorders

of reasonable quality will offer a microphone input with mic trim (usual called

Trim or Gain) control. The purpose of the mic trim control is to optimize the

amount of good signal to any noise associated with the mixers electronics. A

good mic pre with trim also will have a PEAK or CLIP LED. To set a good level

on the mic, set the CL7 up in front of the desired sound source and slowly raise

the mic trim control until you see the PEAK LED light up. Then, turn the mix

trim control down until the LED does not light any more. On most mixers, the

ideal setting is that the trim control is turned up as much as possible without

lighting the PEAK LED.

Using the PAD Switch

The CL7 includes a PAD switch, which

you can use to lower the input sensitiv-

ity of the microphone. When the PAD

switch is set to the 0dB position the

PAD is by-passed and there is no

effect on the signal. When the PAD

switch is set to the –10dB position, the

microphone’s input sensitivity will be

lowered by 10dB. You can use the

PAD when you are miking loud sound

sources with a high SPL (Sound

Pressure Level).

Operating the CL7

Using the Hi-Pass Filter

The CL7 offers a user selectable hi-

pass, (or low-cut filter), which you can

use to eliminate any unwanted low fre-

quency reproduction. When the Hi-

pass Filter is set to the “flat” (indicated

by the straight line) position, there is

no effect on the signal. When the Hi-

pass switch is set to the “roll-off” posi-

tion (indicated with the angled line), a

12dB per octave low-cut at 100Hz is

applied to the signal.

This can be extremely useful for

removing low frequency stage rumble,

wind noise during outdoor use, and fil-

tering out lows from drums when used

as overhead cymbal microphone on a

drum kit.

Polar Pattern

The most important characteristic of any microphone is its directionality or “pick-

up pattern”. There are three basic categories of pick up patterns; omni, bi and

uni-directional. Omni mics pick up sound from all directions, bi-directional (fig-

ure 8) mics pick up the sound directly in front and back of the microphone while

rejecting the sound on the left and right sides, and uni-directional (cardioid) mics

pick up the sound in front of the microphone.

While omni and bi-directional microphones are very useful for a variety of appli-

cations, the majority of “miking” situations in recording and live sound require

uni-directional or cardioid microphones. The uni-directional nature allows for

better separation of instruments in the studio and more control over feedback in

live sound reinforcement. When positioned correctly the hyper-cardioid pick-up

pattern allows you to pick up more of the sound you want and less of the sound

you don’t want.

Microphone Placement

In order to maximize the sound quality, you must pay careful attention to the

placement of your CL7 and how it is positioned for the instrument or vocalist

that you are miking. All microphones, especially uni-directional or cardioid

microphones, exhibit a phenomenon known as “proximity effect.” Very simply

put, proximity effect is a resulting change in the frequency response of a micro-

phone based on the position of the mic capsule relative to the sound source.

Generally, you will get a bass boost when miking in close. When you point a

cardioid mic directly at the sound source (on axis) you will get the best frequen-

cy response, however when you start pointing the microphone slightly away (off

axis) you will notice the low frequency response dropping off and the micro-

phone will start to sound thinner.

For most vocal applications you’ll want to position the microphone directly in

front of the artist. The same may be true for miking instruments, however, you

can make some pretty amazing equalization adjustments by slightly changing

the angle of the capsule to the sound source. This can be a very useful tech-

nique in capturing the optimum sound of drum set, acoustic guitar, piano or

other instruments in a live room or sound stage. Experimentation and experi-

ence are the best teachers in getting good sounds, so plug in!

P-Popping

P-Popping is that annoying pop that you can get when the microphone

diaphragm gets a blast of air from a vocalist pronouncing words with the letter

“P” included. There are a few ways to deal with the problem including using an

external pop filter. Some famous engineers have relied on an old nylon stocking

stretched over a bent clothes hanger, which actually works very well. You can

also try placing the microphone slightly off axis (on a slight angle) from the

vocalist. This can often solve the problem without using an external pop filter.

Stand Mounting the CL7

The CL7 can be mounted to a standard microphone stand using the included

swivel mount adapter. If you are using a U.S. 5/8” mic stand, you will need to

remove, by unscrewing, the Euro stand adapter. Simply screw on the swivel

adapter on your mic stand or boom arm. Now, loosen the thumbscrew and

adjust the microphone to the desired angle. Once set, tighten the thumbscrew

to secure the microphone in place.

Operating the CL7

Using the Optional SP01 “Spider” Shock-Mount

Using the Optional SP01 Shock-Mount

For additional isolation the CL7 can be fit-

ted on the optional SP01 “Spider” shock

mount. Follow the steps below to install

the SP01.

•First, screw the SP01 shock mount

onto your mic stand or boom arm. If

you’re using a US 5/8” mic stand or

boom, remove the Euro adapter.

•Remove the CL7 swivel mount by

rotating the threaded collar counter-

clockwise as shown in figure 1.

• Install the CL7 into the SP01 by fitting

the microphone into the center of the

web, positioning the CL7 onto the bot-

tom mounting plate.

•Secure the SP01 by reinstalling the

threaded collar, rotating clockwise

until tight. (Figure 2)

•Now, loosen the thumb screw to

adjust the angle of the microphone

and position the CL7 to the desired

location. Once set, tighten the thumb-

screw to secure the microphone in

place.

Note: Be careful not to cross thread

or over tighten the threaded collar or

thumb screw.
